• Windows XP Video Configuration Issues

  - by Matt

  Recently I had my motherboard burn out on me. Needing the machine for work, I purchased a different motherboard and installed that. Generally a reinstall of windows is good at that point but I am not in a position to do that so I just decided I would live with it for now. When I can log-in, everything works fine, what doesn't is getting to the log-in prompt to begin with. Basically when I first installed the new mobo, every time I rebooted the machine, I would not get the windows login prompt. One of the monitors would receive a signal but the screen would be black. Moving the mouse would not show the cursor and hitting the up arrow key and typing my password and hitting enter (which will normally log you in without mouse) wouldn't change anything. I would then change the monitor configuration around (2 lcd's and a crt) and reboot and at least one of the monitors would work and display the login prompt. I could then go into display properties and turn on the other monitors. However if I rebooted again, I would get the black screen on one monitor again. I would then have to change the configuration again to one not used before and I could re-do the manual setup at that point. I think windows saves the configurations so I had to keep giving it new ones. Needless to say I've been trying to not turn off my machine. Early this week I actually got the prompt to come up without playing musical monitors. Thinking everything was getting better, I found no harm in rebooting to install the latest windows updates. Boy was I wrong. Now no matter what I do I can't get a windows log-in prompt to display. I've tried almost every conceivable combination. The new mobo has onboard video so I set that in the bios (yea bios screen always displays fine, its not until windows boots that there is a problem) to be the primary video. Still no luck. I have two other graphics cards in the machine which I'm using. Tried all kinds of configurations between those and on-board but still get this black screen of death. I read somewhere that deleting the video drivers would reset the configurations. I logged into safe mode (which works on one monitor), and uninstalled the display drivers. Still no luck and when I booted back into safe mode, it wanted to install new hardware and the display adapters weren't there as expected. Anyone have any ideas? A fresh install would be a pain and I might be getting my old board back from RMA soon so not sure I want to go through with that just yet. Only thing I can think of is to continue to try other combinations like physically removing the graphics cards. They are both EVGA 8600 cards and the windows boot screen does display fwiw.

• hostapd running on Ubuntu Server 13.04 only allows single station to connect when using wpa

  - by user450688

  Problem Only a single station can connect to hostapd at a time. Any single station can connect (W8, OSX, iOS, Nexus) but when two or more hosts are connected at the same time the first client loses its connectivity. However there are no connectivity issues when WPA is not used.

• XenServer Converting HVM to Paravirtualised

  - by Karl Kloppenborg

  Recently I have been tasked with the daunting process of converting a setup of HVM enabled VMs (running on Citrix XenServer 5.6.0) into PV (paravirtualised) containers. The constraints of the project was that: The operating system must be functionally identical after the migration. minimal modification to the operating system (with exception of kernel / drive mapping) I also was allowed to change the bootloader(ie, grub) in what ever way I see fit. However, I have attempted this, I will firstly like to show you my steps I took. This at the moment is CentOS5.5 specific: Steps: yum install kernel-xen This installed: 2.6.18-194.32.1.el5xen edited: /boot/grub/menu.lst changed my specs to match: title CentOS (2.6.18-194.32.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-194.32.1.el5xen ro root=/dev/VolGroup00/LogVol00 console=xvc0 initrd /initrd-2.6.18-194.32.1.el5xen.img Then I changed my xenserver parameters to match: xe vm-param-set uuid=[vm uuid] PV-bootloader-args="--kernel /vmlinuz-2.6.18-194.32.1.el5xen --ramdisk /initrd-2.6.18-194.32.1.el5xen.img" xe vm-param-set uuid=[vm uuid] HVM-boot-policy="" xe vm-param-set uuid=[vm uuid] PV-bootloader=pygrub xe vbd-param-set uuid==[Virtual Block Device/VBD uuid] bootable=true Some things to note, I am running a VolGroup LVM ;) Anyways, after all these steps (which aren't much!) I boot the VM and it boots initial kernel just fine, however I am presented with this error: Boot Screen: device-mapper: dm-raid45: initialized v0.2594l Waiting for driver initialization. Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... Activating logical volumes Volume group "VolGroup00" not found Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems. Setting up new root fs setuproot: moving /dev failed: No such file or directory no fstab.sys, mounting internal defaults setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory Switching to new root and running init. unmounting old /dev unmounting old /proc unmounting old /sys switchroot: mount failed: No such file or directory Now my hints are that it cannot detect / because of the fact that when you change from HVM mode to PV it does something (not that obvious) When you make a SR (storage) on a HVM, you get it mounted to the guest os as /dev/hda. However in PV mode, this presents itself as /dev/xvda... Could this be the answer? and if so, how the heck to I implement it?? Update: So I have gotten a bit further in my quest, as it now detects the LVM's... To do this, I required to recompile the xen-kernel initrd image. Command: mkinitrd -v --builtin=xen_vbd --preload=xenblk initrd-2.6.18-194.32.1.el5xen.img 2.6.18-194.32.1.el5xen Now when I boot I get this: Boot Screen: Loading dm-raid45.ko module device-mapper: dm-raid45: initialized v0.2594l Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes.

• SNTP, why do you mock me?!

  - by Matthew

  --- SOLVED SEE EDIT 5 --- My w2k3 pdc is configured as an authoritative time server. Other servers on the domain are able to sync with it if I manually specify it in the peer list. By if I try to sync from flags 'domhier', it wont resync; I get the error message The computer did not resync because no time data was available. I can only think that it is not querying the pdc. I also tried setting the registry as shown here (http://support.microsoft.com/kb/193825). But no luck (I have not restarted the server, I am hoping I wont have to since it is the pdc) If you would like any further information on my config, please let me know. Edit 1: I have set the w32time service config AnnouceFlags to 0x05 as documented here www.krr.org/microsoft/authoritative_time_servers.php and a number of other places. The PDC syncs to an external time source (ntp). I can get the stripchart on the client from the pdc no problems. The loginserver for the host I am trying to configure is shown as the pdc. Edit 2: The packet capture has revealed something interesting. The client is contacting the correct server, and getting a valid response but I still get the same error message. Here is the NTP excerpt from the client to the server Flags: 11.. .... = Leap Indicator: alarm condition (clock not synchronized) (3) ..01 1... = Version number: NTP Version 3 (3) .... .011 = Mode: client (3) Peer Clock Stratum: unspecified or unavailable (0) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.015625 sec Root Delay: 0.0000 sec Root Dispersion: 1.0156 sec Reference Clock ID: NULL Reference Clock Update Time: Sep 1, 2010 05:29:39.8170 UTC Originate Time Stamp: NULL Receive Time Stamp: NULL Transmit Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Key ID: DC080000 Here is the reply NTP excerpt from the server to the client Flags: 0x1c 00.. .... = Leap Indicator: no warning (0) ..01 1... = Version number: NTP Version 3 (3) .... .100 = Mode: server (4) Peer Clock Stratum: secondary reference (3) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.00001 sec Root Delay: 0.1484 sec Root Dispersion: 0.1060 sec Reference Clock ID: 192.189.54.17 Reference Clock Update Time: Nov 8,2010 01:18:04.6223 UTC Originate Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Receive Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Transmit Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Key ID: 00000000 Edit 3: dumpreg for paramters on pdc Value Name Value Type Value Data ------------------------------------------------------------------------ ServiceMain REG_SZ SvchostEntry_W32Time ServiceDll REG_EXPAND_SZ C:\WINDOWS\system32\w32time.dll NtpServer REG_SZ bhvmmgt01.domain.com,0x1 Type REG_SZ AllSync and config Value Name Value Type Value Data -------------------------------------------------------------------------- LastClockRate REG_DWORD 156249 MinClockRate REG_DWORD 155860 MaxClockRate REG_DWORD 156640 FrequencyCorrectRate REG_DWORD 4 PollAdjustFactor REG_DWORD 5 LargePhaseOffset REG_DWORD 50000000 SpikeWatchPeriod REG_DWORD 900 HoldPeriod REG_DWORD 5 LocalClockDispersion REG_DWORD 10 EventLogFlags REG_DWORD 2 PhaseCorrectRate REG_DWORD 7 MinPollInterval REG_DWORD 6 MaxPollInterval REG_DWORD 10 UpdateInterval REG_DWORD 100 MaxNegPhaseCorrection REG_DWORD -1 MaxPosPhaseCorrection REG_DWORD -1 AnnounceFlags REG_DWORD 5 MaxAllowedPhaseOffset REG_DWORD 300 FileLogSize REG_DWORD 10000000 FileLogName REG_SZ C:\Windows\Temp\w32time.log FileLogEntries REG_SZ 0-300 Edit 4: Here are some notables from the ntp log file on the pdc.

Ok so I was reading about people with similar problems, some mentioned w32time server settings applied by GPO, but I tested this early on and there were no settings applied to this service by gpo. Others said that the reporting software may not be picking up some old gpo settings applied. So I searched the registry for all w32time instaces. I came across an interesting key that indicated there may be some other ntp software running on the server. Sure enough, I look through the installed software list and there the little F*&%ER is. Uninstalled and now working like a dream. FFFFFFFUUUUUUUUUUUU

• How to setup stunnel so that gmail can use my own smtp server to send messages.

  - by igorhvr

  I am trying to setup gmail to send messages using my own smtp server. I am doing this by using stunnel over a non-ssl enabled server. I am able to use my own smtp client with ssl enabled just fine to my server. Unfortunately, however, gmail seems to be unable to connect to my stunnel port. Gmail seems to be simply closing the connection right after it is established - I get a "SSL socket closed on SSL_read" on my server logs. On gmail, I get a "We are having trouble authenticating with your other mail service. Please try changing your SSL settings.

• ASA 5505 stops local internet when connected to VPN

  - by g18c

  Hi I have a Cisco ASA router running firmware 8.2(5) which hosts an internal LAN on 192.168.30.0/24. I have used the VPN Wizard to setup L2TP access and I can connect in fine from a Windows box and can ping hosts behind the VPN router. However, when connected to the VPN I can no longer ping out to my internet or browse web pages. I would like to be able to access the VPN, and also browse the internet at the same time - I understand this is called split tunneling (have ticked the setting in the wizard but to no effect) and if so how do I do this? Alternatively, if split tunneling is a pain to setup, then making the connected VPN client have internet access from the ASA WAN IP would be OK. Thanks, Chris names ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Vlan1 nameif inside security-level 100 ip address 192.168.30.1 255.255.255.0 ! interface Vlan2 nameif outside security-level 0 ip address 208.74.158.58 255.255.255.252 ! ftp mode passive access-list inside_nat0_outbound extended permit ip any 10.10.10.0 255.255.255.128 access-list inside_nat0_outbound extended permit ip 192.168.30.0 255.255.255.0 192.168.30.192 255.255.255.192 access-list DefaultRAGroup_splitTunnelAcl standard permit 192.168.30.0 255.255.255.0 access-list DefaultRAGroup_splitTunnelAcl_1 standard permit 192.168.30.0 255.255.255.0 pager lines 24 logging asdm informational mtu inside 1500 mtu outside 1500 ip local pool LANVPNPOOL 192.168.30.220-192.168.30.249 mask 255.255.255.0 icmp unreachable rate-limit 1 burst-size 1 no asdm history enable arp timeout 14400 global (outside) 1 interface nat (inside) 0 access-list inside_nat0_outbound nat (inside) 1 192.168.30.0 255.255.255.0 route outside 0.0.0.0 0.0.0.0 208.74.158.57 1 timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00 timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00 timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolute timeout tcp-proxy-reassembly 0:01:00 timeout floating-conn 0:00:00 dynamic-access-policy-record DfltAccessPolicy http server enable http 192.168.30.0 255.255.255.0 inside snmp-server enable traps snmp authentication linkup linkdown coldstart crypto ipsec transform-set ESP-AES-256-MD5 esp-aes-256 esp-md5-hmac crypto ipsec transform-set ESP-DES-SHA esp-des esp-sha-hmac crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac crypto ipsec transform-set ESP-DES-MD5 esp-des esp-md5-hmac crypto ipsec transform-set ESP-AES-192-MD5 esp-aes-192 esp-md5-hmac crypto ipsec transform-set ESP-3DES-MD5 esp-3des esp-md5-hmac crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac crypto ipsec transform-set ESP-AES-128-SHA esp-aes esp-sha-hmac crypto ipsec transform-set ESP-AES-192-SHA esp-aes-192 esp-sha-hmac crypto ipsec transform-set ESP-AES-128-MD5 esp-aes esp-md5-hmac crypto ipsec transform-set TRANS_ESP_3DES_SHA esp-3des esp-sha-hmac crypto ipsec transform-set TRANS_ESP_3DES_SHA mode transport crypto ipsec security-association lifetime seconds 28800 crypto ipsec security-association lifetime kilobytes 4608000 crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set transform-set ESP-AES-128-SHA ESP-AES-128-MD5 ESP-AES-192-SHA ESP-AES-192-MD5 ESP-AES-256-SHA ESP-AES-256-MD5 ESP-3DES-SHA ESP-3DES-MD5 ESP-DES-SHA ESP-DES-MD5 TRANS_ESP_3DES_SHA crypto map outside_map 65535 ipsec-isakmp dynamic SYSTEM_DEFAULT_CRYPTO_MAP crypto map outside_map interface outside crypto isakmp enable outside crypto isakmp policy 10 authentication pre-share encryption 3des hash sha group 2 lifetime 86400 telnet timeout 5 ssh timeout 5 console timeout 0 dhcpd auto_config outside ! threat-detection basic-threat threat-detection statistics access-list no threat-detection statistics tcp-intercept webvpn group-policy DefaultRAGroup internal group-policy DefaultRAGroup attributes dns-server value 192.168.30.3 vpn-tunnel-protocol l2tp-ipsec split-tunnel-policy tunnelspecified split-tunnel-network-list value DefaultRAGroup_splitTunnelAcl_1 username user password Cj7W5X7wERleAewO8ENYtg== nt-encrypted privilege 0 tunnel-group DefaultRAGroup general-attributes address-pool LANVPNPOOL default-group-policy DefaultRAGroup tunnel-group DefaultRAGroup ipsec-attributes pre-shared-key ***** tunnel-group DefaultRAGroup ppp-attributes no authentication chap authentication ms-chap-v2 ! class-map inspection_default match default-inspection-traffic ! ! policy-map type inspect dns preset_dns_map parameters message-length maximum client auto message-length maximum 512 policy-map global_policy class inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect rtsp inspect esmtp inspect sqlnet inspect skinny inspect sunrpc inspect xdmcp inspect sip inspect netbios inspect tftp inspect ip-options ! service-policy global_policy global prompt hostname context : end

• Dell Latitude E6430 Docking Station + Dual Monitor + Laptop Screen Tri-Monitor setup

  - by Larry

  I have a company issued laptop and docking station as well as two monitors The specifications of the hardware are as follows; Laptop: Latitude E6430 BIOS: A02.00 Processor: i7-3720QM CPU @ 2.60 (8 CPUs) Memory: 4096MB RAM Page file: 1825MB used, 4793MB available DirectX 11 Display Driver/Chip: MVIDIA NVS 5200M DAC: Integrated RAMDAC Aprox Total Memory: 2376 (Above 3 details same for both displays) Current Display Mode (Display 1): 1600x900 Current Display Mode (Display 2): 1440x900 the docking station is a Dell Latitude E6420 Docking Station PR03X Port Replicator and I don't think the monitor model is particularly relevant to resolving this issue but they are both Acer V193Ws The story goes like this; the laptop works fine if I VGA one monitor into the laptop through the vga port on the back of the lefthand side of the laptop I can achieve dual monitor display fine (laptop screen + monitor) if I plug the laptop into the docking station and use the vga port in the back of the docking station I can dual monitor fine (laptop screen + monitor) if I plug the laptop into the docking station, the laptop's lefthand side VGA port no longer seems to function at all I've spoken to internal IT about this issue and they're going to get me some kind of VGA splitter or a DVI-VGA adapter to use with the docking station for the second Acer Monitor, but that isn't going to happen for a few days. So I guess what I'm wondering is; is there any way to continue to use the side VGA port on my laptop while using the docking station VGA port? and as a secondary 'followup' pending resolution of the initial issue with getting both monitors up and running (at the moment I have both monitors on my desk but am just using my laptop screen as one of my dual monitor display with one of the monitors [the one connected to dock]), is there any way to CONTINUE to use my laptop monitor to in effect have a triple monitor display (2 monitors + docked laptop)? I am wondering this because internal IT told me that they were aware of some issues with the particular display drivers in my box and triple monitor displays but weren't really going to look TOO much in-depth into that (which is perfectly understandable) since getting the adapter for the dual monitors up and running was the greater priority within their purview. So this is a two parter; Can I dual monitor using two vga cables with 1 docking station vga port and one laptop vga port? is there a setting that can be tweaked somewhere? because plugging the box into the station seems to make the side port stop working and... Is there any reasonably simple and cost-effective work around (e.g. I am find with shelling out maybe a few dollars out of my own pocket for some hardware or software to make my company box tri-display capable) but if this requires some extensive rebuild or new OSs or doing stuff to the BIOS I'd rather have a straight answer about this being untenable as a slight modification to a (once again) company laptop and stop wasting time looking into it Thanks! and please let me know if you guys need any more details (tech specs or something) to answer this question [EDIT] 2/10/2014 Just an update; turned out it really was just a hardware limitation issue. The old laptop just couldn't hack it. Got a new laptop with a better video card and different monitors from my company and am successfully using a triple display currently (2 monitors + laptop screen)

• Do hard drive enclosures fail/is it the HDD or enclosure?

  - by x0a

  I'm having a whole host of problems with an external hard drive that was working just fine a couple of hours ago. I've had this problem before once, and that was about 3 months ago, here's what I documented: So a couple of hours ago I turned off all my computers and shut off the power to all my devices in my room, then went and turned the power off at the main switch so I could change an outlet. A couple hours later, after I've already slowly turned everything back on, I go to my xbox to try and watch a movie and it can't seem to list any of the movies I've got. So I go to my desktop to find that my external hard drive isn't there.. even though it's on and connected. It's also stationary and hidden behind something so there's not a whole lot of tampering/physical wear to that external. I plug it into my laptop to try and see what's going on. It starts making this endless loud screeching noise. None of that clicking that's usually associated with hd damage. It's not listed in my computers, and it shows up in Disk Management as "uninitialized" asking me to choose between two different partition types. After carefully disconnecting it and connecting it back, it asks me to format it, which I cancel. I start googling about my issue, starting to accept the situation, torn as hell and helpless and just about ready to toss the thing. Suddenly the screeching stops, after almost 45 minutes of it going, and Disk Management lists the drive as "Online" and "Healthy". Explorer pops up with all my files! I'm still being really careful with it and weary and treating it as though it's in fragile shape. I've downloaded some S.M.A.R.T. software to read the values and everything is listed as "OK" . No reallocated sectors, no read errors, no seek errors. I also ran a quick self-test, which completed without error. Everything seems fine. It looks to be a perfectly healthy external hard drive. So what the hell was that about? Was it doing some sort of maintenance or self-test? How am I supposed to tell the difference? I would've undoubtedly killed the drive for sure if had it gone on a bit longer. I've got the same problem now, with one exception: it doesn't magically reappear after the screeching stops. Occasionally I manage to get some S.M.A.R.T. diagnostics information, which basically reads everything as fine. The only problem is that my HD isn't initializing (so I can't access anything in it). I'm able to successfully run a quick smart test but not an extended one (I've only tried it once but got conflicting indications as to whether it was actually making any progress or not (was stuck on Random read test). So, final question (if all else fails): Could the hard drive enclosure be failing rather than the HDD? Is this a likely possibility at all? How would I know?

• Installing .NET application on IIS 7.5 issues

  - by Juw

  Really need some help here. I am at a loss. I am trying to install a webservice that some other guy wrote in .NET. I have some basic IIS understanding. The webservice works just fine on my dev computer. But now i try to move the webservice to a production server and bad things happens. The webservice has been located in C:\inetpub\wwwroot\ dir on the dev server. But on this production server it is to be located in D:\services\ I have managed to install an application on the production server and everything seems fine and dandy. But when i "Test Settings" in the initial setup i get "Invalid application path" error. But i can just close it down and still install it. But when i try to access the webservice with: http://myserver.com/webservice/GetData nothing happens. Just a blank page and when i check the response headers...500 error. I don´t know what is going on here or where the problem is. I post the config file here so someone hopefully might notice something odd. Thanx in advance! EDIT: The config file is from my dev server. I just copied it to my production server...but that obviously didn´t work :-) UPDATE: I noticed that my dev server run in an Application pool with Net 4 and in "classic" "mode". On the production server it was in NET 4 but in "integrated" mode. So i changed it to "classic". I still get a blank page. But checking the log will output this: 2012-10-03 14:57:00 ip removed GET /boo/GetData - 80 - ip removed Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:15.0)+Gecko/20100101+Firefox/15.0.1 404 2 1260 203 <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <identity impersonate="true" /> <!-- Impersonate NT AUTHORITY/IUSR --> <compilation targetFramework="4.0"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b7735c561131e089" /> </assemblies> </compilation> <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID" /> </system.web> <system.webServer> <modules runAllManagedModulesForAllRequests="true" /> <httpErrors existingResponse="PassThrough" /> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtocol> <directoryBrowse enabled="false" /> </system.webServer> <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <standardEndpoints> <webHttpEndpoint> <!-- Configure the WCF REST service base address via the global.asax.cs file and the default endpoint via the attributes on the <standardEndpoint> element below --> <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" /> </webHttpEndpoint> </standardEndpoints> </system.serviceModel> <connectionStrings> <add name="Entities" connectionString="metadata=res://*/DataModel.csdl|res://*/DataModel.ssdl|res://*/DataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=someip;initial catalog=db_90;User ID=user1;Password=access2;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> </configuration>

• Clarification On Write-Caching Policy, Its Underlying Options And How It Applies To Hard Drives And Solid-State Drives

  - by Boris_yo

  In last week after doing more research on subject matter, I have been wondering about what I have been neglecting all those years to understand write-caching policy, always leaving it on default setting. Write-caching policy improves writing performance and consists of write-back caching and write-cache buffer flushing. This is how I understand all the above, but correct me if I erred somewhere: Write-through cache / Write-through caching itself is not a part of write caching policy per se and it's when data is written to both cache and storage device so if Windows will need that data later again, it is retrieved from cache and not from storage device which means only improved read performance as there is no need for waiting for storage device to read required data again. Since data is still written to storage device, write performance isn't improved and represents no risk of data loss or corruption in case of power failure or system crash while only data in cache gets lost. This option seems to be enabled by default and is recommended for removable devices with no need to use function of "Safely Remove Hardware" on user's part. Write-back caching is similar to above but without writing data to storage device, periodically releasing data from cache and writing to storage device when it is idle. In my opinion this option improves both read and write performance but represents risk if power failure or system crash occurs with the outcome of not only losing data eventually to be written to storage device, but causing file inconsistencies or corrupted file system. Write-back caching cannot be enabled together with write-through caching and it is not recommended to be enabled if no backup power supply is availabe. Write-cache buffer flushing I reckon is similar to write-back caching but enables immediate release and writing of data from cache to storage device right before power outage occurs but I don't know if it applies also to occasional system crash. This option seem to be complementary to write-back cache reducing or potentially eliminating risk of data loss or corruption of file system. I have questions about relevance of last 2 options to today's modern SSDs in order to get best performance and with less wear on SSDs: I know that traditional hard drives come with onboard cache (I wonder what type of cache that is), but do SSDs also come with cache? Assuming they do, is this cache faster than their NAND flash and system RAM and worth taking the risk of utilizing it by enabling write-back cache? I read somewhere that generally storage device's cache is faster than RAM, but I want to be sure. Additionally I read that write-caching should be enabled since current data that is to be written later to NAND flash is kept for a while in cache and provided there is data that gets modified a lot before finally being written, holding of this data and its periodic release reduces its write times to SSD thereby reducing its wearing. Now regarding to write-cache buffer flushing, I heard that SSD controllers are so fast by themselves that enabling this option is not required, because they manage flushing. However, once again, I don't know if SSDs have their own onboard cache and whether or not it is faster than their NAND flash and system RAM because if it is, keeping this option enabled would make sense. Recently I have posted question about issue with my Intel 330 SSD 120GB which was main reason to do deeper research having suspicion of write-caching policy being the culprit of SSD's freezing issue assuming data being released is what causes freezes. Currently I have write-cache enabled and write-cache buffer flushing disabled because I believe SSD controller's management of write-cache flushing and Windows write-cache buffer flushing are conflicting with each other: Since I want to troubleshoot in small steps to finally determine the source of issue, I have decided to start with write-caching policy and the move to drivers, switching to AHCI later on and finally disabling DIPM (device initiated power management) through registry modification thanks to @TomWijsman

• Vista 64-bit, DISK BOOT FAILURE

  - by weka

  So I have this Acer Aspire AX3200-U3600A with Windows Vista (64-bit). Every night I turn it off and turn it back on in the morning. Around three weeks ago, I did a fresh factory reimage. Good as new. Then around two days ago, when I turned it on, I noticed it was running extremly slow. As in, it would often freeze up while I had multiple applications open when it usually never froze up. So I decided to restart my computer. Big mistake. My computer froze right after I clicked shut-down. I waited a while. Nothing. Waited some minutes. Nope. I decided to shut it down by pressing the power button. Here is where the problems begin. When I turned it back on, I saw the Windows logo and loading bar and then it loaded to black. I turned it off again forcefully by power button and then once more... then I got: AMD Data Change... Update New Data to DMI! then later the screen clears and I get: AHCI Option ROM BIOS Revision: 01.05.92 Date: 02-19-2008 Copyright (c) 2006-2008 Phoenix Technologies, LTD Port 01: Reset Port Error!! Port 02: then the screen clears again but this time, this loads from the bottom: Nvidia Boot Agent 249.0542 (copyright stuff... blah blah) PXE-E61: Media test failure, check cable. PXE-M0F: Exiting Nvidia Boot Agent DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. So I try to go into Safe Mode. Well, first of all it doesn't load as fast. After it loads disk.sys from windows/drivers, it will wait a while (2-3 mins) THEN load. However it loads the Acer eRecovery Management Tool. I have three options: Reset computer to factory default, Restore computer from user's backup, or Exit. However, the top two options are gray and disabled where as the Exit is in blue and definitely clickable. So obviously safe mode is not there... A strong thing to note: In the beginning when all of this started, I did a Boot Windows Normal from pressing f8 and I got to my desktop! It logged me in. I could see the icons on my files. However my desktop was extremely slow as in when I clicked on the Start menu, it would wait a while, then load up the menu with JUST the gradient, no text or icons... so as you can see... it saw my HDD? Also, before anyone says, I have NO USB plugged in. My mouse and keyboard are not USB inputs, I assure you. And this came without a recovery CD AND when I went in BIOS, to change the BOOT ORDER, I did NOT see a CD-ROM option. And when I tried pressing ALT+F10 to get into Acer eRecovery Management, the top two options were disabled as well. But sometimes on start-up, I get: Windows has encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removeable storage is properly connected and then restart your computer. If you continue to receive this error message, contact the hardware manufacturer. Status: 0xc00000e9 Info: An unexpected I/O error has occured. Then I tried Last Known Good Configuration Settings, that gives me a BSOD. What should I do/

• Windows 8.1 Update 1 Disk Usage 100%

  - by Gookjin Jeong

  Background Information / Computer Specs I have a 14-inch Samsung Series 5 Ultra. Core i5 CPU, 750GB HDD, 8GB RAM, Intel HD Graphics 4000. I've had the computer for about 1.5 years with no major problems. Problem The issue appeared at the beginning of April this year, when I updated the OS to Windows 8.1 Update 1 (not from 8 to 8.1). After being on continually (except for at night, when I put it on sleep mode) for about 48 hours, the disk usage as seen by Task Manager hits 100%. When this happens, everything from opening/closing applications to typing and even bringing up the start screen by pressing the Windows key becomes extremely slow. The only way to make the disk usage decrease is to restart the computer. Then the problem repeats. I've used my current laptop (as well as my previous laptops) this way -- putting it on sleep mode at night and restarting it only when Windows needs to install updates -- for a long time. So I know the 100% disk usage is not due to the way I use the computer. The thing that causes the spike varies. Sometimes it's System, sometimes it's one of the various applications I installed (e.g. Chrome, Evernote, Spotify, Wunderlist, iTunes, etc.), and sometimes it's Antimalware Service Executable, etc. Tried Solutions I think I tried almost every solution out there for this problem: Running the check disk command (chkdsk /b /f /v /scan c:) from Admin Command Prompt Running Windows Memory Diagnostic Disabling Superfetch and Windows Search from services.msc Running "Fix problems with Windows Update" from Control Panel -- Troubleshooting Updating and rolling back the graphics driver (Intel HD 4000) Disabling "Use hardware acceleration when available" from Chrome settings Disabling Intel Rapid Storage Technology Running the SFC /SCANNOW command as recommended here Running a quick scan & a full scan from Windows Defender (no threats found) Taking the hard drive out and putting it back Refreshing the computer, from the Update and recovery -- Recovery option in Windows settings NONE of the above worked for me. I was about to give up but then noticed that one of the main culprits of the disk usage spike, as shown in the "Disk Activity" section of the Resource Monitor, was C:\System (pagefile.sys). I googled around and found that one of the recommended solutions was to disable pagefile. I then went to **Control Panel -- System and Security -- System -- Advanced system settings -- Advanced tab -- Performance settings -- Advanced tab -- "Change" under Virtual memory and discovered that the number for "Currently allocated" at the bottom was 1280MB, although the number for "Recommended" was 4533MB. I immediately changed it to 4533MB and checked my family members' computers to see what the numbers were like. All of theirs had a currently allocated space that was only slightly smaller than the recommended space. See screenshot below: This might fix the problem. I'll have to wait a couple more days.But if it doesn't, what in the world should I do next? I'm guessing the hard drive isn't failing because This computer is less than 2 years old; and Speccy says that the status of the HDD is good. Update 5/27/2014 The "4533MB" solution did not work. I had to reboot the computer about 30 minutes ago because the disk usage again hit 100%. When I opened Resource Monitor the C:\System (pagefile.sys) again was shown to be the culprit. I have now disabled pagefile entirely via the same window shown above in the screenshot. The number for "currently allocated" is now 0MB. Will update again in a couple days, or if the problem occurs again, whichever comes sooner.

• Lockdown users on Windows Server 2012

  - by el.severo

  I set up a Active Directory on a server machine with Windows Server 2012 and I'd like to create some users with limitations like Windows Steady State does in Windows XP (locally). Seen already the Windows SteadyState Handbook (with Windows Server 2008), but I'd like to know if anyone has tried this before, the limitations are the following: 1. Prevent locked or roaming user profiles that cannot be found on the computer from logging on 2. Do not cache copies of locked or roaming user profiles for users who have previously logged on to this computer 3. Do not allow Windows to compute and store passwords using LAN Manager Hash values 4. Do not store usernames or passwords used to log on to the Windows Live ID or the domain 5. Prevent users from creating folders and files on drive C:\ 6. Lock profile to prevent the user from making permanent changes 7. Remove the Control Panel, Printer and Network Settings from the Classic Start menu 8. Remove the Favorites icon 9. Remove the My Network Places icon 10. Remove the Frequently Used Program list 11. Remove the Shared documents folder from My Computer 12. Remove control Panel icon 13. Remove the Set Program Access and Defaults icon 14. Remove the Network Connection(Connect To)icon 15. Remove the Printers and Faxes icon 16. Remove the Run icon 17. Prevent access to Windows Explorer features: Folder Options, Customize Toolbar, and the Notification Area 18. Prevent access to the taskbar 19. Prevent access to the command prompt 20. Prevent access to the registry editor 21. Prevent access to the Task Manager 22. Prevent access to Microsoft Management Console utilities 23. Prevent users from adding or removing printers 24. Prevent users from locking the computer 25. Prevent password changes (also requires the Control Panel icon to be removed) 26. Disable System Tools and other management programs 27. Prevent users from saving files to the desktop 28. Hide A Drive 29. Hide B Drive 30. Hide C Drive 31. Prevent changes to Internet Explorer registry settings 32. Empty the Temporary Internet Files folder when Internet Explorer is closed 33. Remove Internet Options 34. Remove General tab in Internet Options 35. Remove Security tab in Internet Options 36. Remove Privacy tab in Internet Options 37. Remove Content tab in Internet Options 38. Remove Connections tab in Internet Options 39. Remove Programs tab in Internet Options 40. Remove Advanced tab in Internet Options 41. Set a home page (Internet Explorer) 42. Restrict the possibility to change desktop image 43. Restrict the possibility to change wallpaper 44. Restrict usb flash drives Any suggestions for this? UPDATE: As @Dan suggested me I'd like to specify that would be applied to a educational scenario where students can login from a computer and want to add some restrictions to them.

• Is there a bug with Apache 2.2 and content filters (and maybe mod_proxy)?

  - by asciiphil

  I'm running Apache 2.2.15-29 on RHEL 6 (actually Scientific Linux 6.4) and I'm trying to set up a reverse proxy with content rewriting so all of the links on the proxied web pages are rewritten to reference the proxy host. I'm running into a problem with some of the content rewriting and I'd like to know if this is a bug or if I'm doing something wrong (and how to do it right, if applicable). I'm proxying a subdirectory on an internal host (internal.example.com/foo) onto the root of an external host (external.example.com). I need to rewrite HTML, CSS, and Javascript content to fix all of the URLs. I'm also hosting some content locally on the external host, which I don't think is a problem but I'm mentioning here for completeness. My httpd.conf looks roughly like this: <VirtualHost *:80> ServerName external.example.com ServerAlias example.com # Serve all local content directly, reverse-proxy all unknown URIs. RewriteEngine On RewriteRule ^(/(index.html?)?)?$ http://internal.example.com/foo/ [P] RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -f [OR] RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -d RewriteRule ^.*$ - [L] RewriteRule ^/~ - [L] RewriteRule ^(.*)$ http://internal.example.com$1 [P] # Standard header rewriting. ProxyPassReverse / http://internal.example.com/foo/ ProxyPassReverseCookieDomain internal.example.com external.example.com ProxyPassReverseCookiePath /foo/ / # Strip any Accept-Encoding: headers from the client so we can process the pages # as plain text. RequestHeader unset Accept-Encoding # Use mod_proxy_html to fix URLs in text/html content. ProxyHTMLEnable On ProxyHTMLURLMap http://internal.example.com/foo/ / ProxyHTMLURLMap http://internal.example.com/foo / ProxyHTMLURLMap /foo/ / ## Use mod_substitute to fix URLs in CSS and Javascript #<Location /> # AddOutputFilterByType SUBSTITUTE text/css # AddOutputFilterByType SUBSTITUTE text/javascript # Substitute "s|http://internal.example.com/foo/|/|nq" #</Location> # Use mod_ext_filter to fix URLs in CSS and Javascript ExtFilterDefine fixurlcss mode=output intype=text/css cmd="/bin/sed -rf /etc/httpd/fixurls" ExtFilterDefine fixurljs mode=output intype=text/javascript cmd="/bin/sed -rf /etc/httpd/fixurls" <Location /> SetOutputFilter fixurlcss;fixurljs </Location> </VirtualHost> The text/html rewriting works just fine. When I use either mod_substitute or mod_ext_filter, the external server sends the pages as Transfer-Encoding: chunked, sends all of the data, and then closes the connection without sending the final, zero-length chunk. Some HTTP clients are unhappy with this. (Chrome won't process any content sent in this way, for example, so the pages don't get CSS applied to them.) Here's a sample wget session: $ wget -O /dev/null -S http://external.example.com/include/jquery.js --2013-11-01 11:36:36-- http://external.example.com/include/jquery.js Resolving external.example.com (external.example.com)... 192.168.0.1 Connecting to external.example.com (external.example.com)|192.168.0.1|:80... connected.

Am I doing something wrong? Am I hitting some sort of Apache bug? What do I need to do to get it working? (Note that I'd prefer solutions that work within RHEL-6-packaged RPMs and upgrading to Apache 2.4 would be a last resort, as we have a lot of infrastructure built around 2.2 on this system at the moment.)

• Integrate SharePoint 2010 with Team Foundation Server 2010

  - by Martin Hinshelwood

  Our client is using a brand new shiny installation of SharePoint 2010, so we need to integrate our upgraded Team Foundation Server 2010 instance into it. In order to do that you need to run the Team Foundation Server 2010 install on the SharePoint 2010 server and choose to install only the “Extensions for SharePoint Products and Technologies”. We want out upgraded Team Project Collection to create any new portal in this SharePoint 2010 server farm. There a number of goodies above and beyond a solution file that requires the install, with the main one being the TFS2010 client API. These goodies allow proper integration with the creation and viewing of Work Items from SharePoint a new feature with TFS 2010. This works in both SharePoint 2007 and SharePoint 2010 with the level of integration dependant on the version of SharePoint that you are running. There are three levels of integration with “SharePoint Services 3.0” or “SharePoint Foundation 2010” being the lowest. This level only offers reporting services framed integration for reporting along with Work Item Integration and document management. The highest is Microsoft Office SharePoint Services (MOSS) Enterprise with Excel Services integration providing some lovely dashboards. Figure: Dashboards take the guessing out of Project Planning and estimation. Plus writing these reports would be boring!   The Extensions that you need are on the same installation media as the main TFS install and the only difference is the options you pick during the install. Figure: Installing the TFS 2010 Extensions for SharePoint Products and Technologies onto SharePoint 2010   Annoyingly you may need to reboot a couple of times, but on this server the process was MUCH smother than on our internal server. I think this was mostly to do with this being a clean install. Once it is installed you need to run the configuration. This will add all of the Solution and Templates that are needed for SharePoint to work properly with TFS. Figure: This is where all the TFS 2010 goodies are added to your SharePoint 2010 server and the TFS 2010 object model is installed.   Figure: All done, you have everything installed, but you still need to configure it Now that we have the TFS 2010 SharePoint Extensions installed on our SharePoint 2010 server we need to configure them both so that they will talk happily to each other. Configuring the SharePoint 2010 Managed path for Team Foundation Server 2010 In order for TFS to automatically create your project portals you need a wildcard managed path setup. This is where TFS will create the portal during the creation of a new Team project. To find the managed paths page for any application you need to first select the “Managed web applications”  link from the SharePoint 2010 Central Administration screen. Figure: Find the “Manage web applications” link under the “Application Management” section. On you are there you will see that the “Managed Paths” are there, they are just greyed out and selecting one of the applications will enable it to be clicked. Figure: You need to select an application for the SharePoint 2010 ribbon to activate.   Figure: You need to select an application before you can get to the Managed Paths for that application. Now we need to add a managed path for TFS 2010 to create its portals under. I have gone for the obvious option of just calling the managed path “TFS02” as the TFS 2010 server is the second TFS server that the client has installed, TFS 2008 being the first. This links the location to the server name, and as you can’t have two projects of the same name in two separate project collections there is unlikely to be any conflicts. Figure: Add a “tfs02” wildcard inclusion path to your SharePoint site. Configure the Team Foundation Server 2010 connection to SharePoint 2010 In order to have you new TFS 2010 Server talk to and create sites in SharePoint 2010 you need to tell the TFS server where to put them. As this TFS 2010 server was installed in out-of-the-box mode it has a SharePoint Services 3.0 (the free one) server running on the same box. But we want to change that so we can use the external SharePoint 2010 instance. Just open the “Team Foundation Server Administration Console” and navigate to the “SharePoint Web Applications” section. Here you click “Add” and enter the details for the Managed path we just created. Figure: If you have special permissions on your SharePoint you may need to add accounts to the “Service Accounts” section.    Before we can se this new SharePoint 2010 instance to be the default for our upgraded Team Project Collection we need to configure SharePoint to take instructions from our TFS server. Configure SharePoint 2010 to connect to Team Foundation Server 2010 On your SharePoint 2010 server open the Team Foundation Server Administration Console and select the “Extensions for SharePoint Products and Technologies” node. Here we need to “grant access” for our TFS 2010 server to create sites. Click the “Grant access” link and  fill out the full URL to the  TFS server, for example http://servername.domain.com:8080/tfs, and if need be restrict the path that TFS sites can be created on. Remember that when the users create a new team project they can change the default and point it anywhere they like as long as it is an authorised SharePoint location. Figure: Grant access for your TFS 2010 server to create sites in SharePoint 2010 Now that we have an authorised location for our team project portals to be created we need to tell our Team Project Collection that this is where it should stick sites by default for any new Team Projects created. Configure the Team Foundation Server 2010 Team Project Collection to create new sites in SharePoint 2010 Back on out TFS 2010 server we need to setup the defaults for our upgraded Team Project Collection to the new SharePoint 2010 integration we have just set up. On the TFS 2010 server open up the “Team Foundation Server Administration Console” again and navigate to the “Team Project Collections” node. Once you are there you will see a list of all of your TPC’s and in our case we have a DefaultCollection as well as out named and Upgraded collection for TFS 2008. If you select the “SharePoint Site” tab we can see that it is not currently configured. Figure: Our new Upgrade TFS2008 Team Project Collection does not have SharePoint configured Select to “Edit Default Site Location” and select the new integration point that we just set up for SharePoint 2010. Once you have selected the “SharePoint Web Application” (the thing we just configured) then it will give you an example based on that configuration point and the name of the Team Project Collection that we are configuring. Figure: Set the default location for new Team Project Portals to be created for this Team Project Collection This is where the reason for configuring the Extensions on the SharePoint 2010 server before doing this last bit becomes apparent. TFS 2010 is going to create a site at our http://sharepointserver/tfs02/ location called http://sharepointserver/tfs02/[TeamProjectCollection], or whatever we had specified, and it would have had difficulty doing this if we had not given it permission first. Figure: If there is no Team Project Collection site at this location the TFS 2010 server is going to create one This will create a nice Team Project Collection parent site to contain the Portals for any new Team Projects that are created. It is with noting that it will not create portals for existing Team Projects as this process is run during the Team Project Creation wizard. Figure: Just a basic parent site to host all of your new Team Project Portals as sub sites   You will need to add all of the users that will be creating Team Projects to be Administrators of this site so that they will not get an error during the Project Creation Wizard. You may also want to customise this as a proper portal to your projects if you are going to be having lots of them, but it is really just a default placeholder so you have a top level site that you can backup and point at. You have now integrated SharePoint 2010 and team Foundation Server 2010! You can now go forth and multiple your Team Projects for this Team Project Collection or you can continue to add portals to your other Collections.   Technorati Tags: TFS 2010,Sharepoint 2010,VS ALM

• Getting Started with Boxee

  - by DigitalGeekery

  Boxee is a free Media PC application that runs on Windows, Mac, and Ubuntu Linux. With Boxee, you can integrate online video, music and pictures, with your own local media and social networking. Today we are going to take a closer look at Boxee and some of it’s features. Note: We used Windows 7 for this tutorial. Your experience on a Mac or Ubuntu Linux build may vary slightly. Hardware Requirements x86 (Intel/AMD processor) based system running at 1.0GHz or greater 512MB system memory (RAM) or more Video card capable of OpenGL 1.4, Direct X 9.0 Software Requirements Mac OS X 10.4+ (Intel based processor) Ubuntu Linux 9.04+ x86 only Windows XP / Vista / 7 (64 bit in Vista or 7) Installing Boxee Before downloading and installing Boxee, you’ll need to register for a free account. (See link below) Once your account is registered and verified, you’ll be able to log in and download the application. Installation is pretty straightforward…just take the defaults. Boxee will open in full screen mode and you’ll be prompted to login with your username and password. Before you login, you may want to take a moment to click on the “Guide” icon and learn a bit about navigating in Boxee. Some basic keyboard navigation is as follows. Move right, left, up, & down with the arrow keys. Hit “Enter” to make a selection, the forward slash key “\” to toggle between full screen and windowed mode, and “Esc” to go back to the previous screen. For Playback, the volume is controlled by plus & minus (+/-) keys, you can Play / Pause using the spacebar, and skip using the arrow keys. Boxee will also work with any infrared remote. If you have an iPhone or iPod Touch you can download software to enable them as a Boxee remote. If you’re using a mouse and keyboard, hover over the username and password boxes to enter your login credentials. If using a a remote, click your OK button and enter credentials with the on screen keyboard. Click “Done” when finished.   When you are ready to login, enter your credentials and click “Login.” On first login, you’ll be prompted to calibrate your screen. If you choose “Skip” you can always calibrate your screen later under Settings > Appearance > Screen. When Boxee opens, you’ll be greeted by the Home screen. To the left will be your Feeds. This will be any recommended content from friends on Boxee, and social networks such as Facebook and Twitter. Although, when you first login, it will mainly be info from the Boxee staff. You’ll have “Featured” content in the center and your Queue on the right. You’ll also have the Menu along the top.   Pop Up Menu The Pop Menu can be accessed by hitting the “Esc” key, or back on your remote. Depending on where you are located in Boxee, you may have to hit it a few time to “back out” to the Pop Up menu. From the Pop Up Menu, you can easily access any of the resources, settings, and favorites. Queue The Queue is your playlist of TV shows, movies, or Internet videos you wish to watch. When you find an offering you’d like to watch, select it and then click “Add to Queue.” The selected item will be added to your Queue and can be accessed at any time from the Menu. TV Show Library The TV Show library can contain files from your local hard drive or streaming content from the Web. Boxee pulls content from a variety of online locations such as Hulu and TV network sites. Click on the show to see which specific episodes are currently available. To search for your favorite shows, click on the yellow arrow to the left, or navigate to the left with your keyboard or remote. Enter your selection into the search box. My Apps By default, the “My Apps” section includes a list of the most popular apps, such as Netflix, Pandora, YouTube, and others. You can remove Apps from “My Apps,” or add new Apps from the Apps Library.   To access all the available Apps, click on the left arrow button, or click on the yellow arrow at the left, then select “App Library.” Choose an App from the Library and click it to open… … and then select “Add to My Apps.” Or, you can click start to play the App if you don’t wish to Add it to your “My Apps.”   Music, Pictures, and Movies Boxee will scan your PC for movies, pictures, and music. You can choose to scan specific folders by clicking on “Scan Media Folders…” … or from the Pop Up Menu, selecting Settings > Media, and then browsing for your media.   Conclusion Boxee to be a great way to integrate your local media with online streaming content. It can be run as an application on your home PC, or as a stand alone media PC. It should also be noted, however, that your access to online content will vary depending on your country.

• Understanding 400 Bad Request Exception

  - by imran_ku07

      Introduction:          Why I am getting this exception? What is the cause of this error. Developers are always curious to know the root cause of an exception, even though they found the solution from elsewhere. So what is the reason of this exception (400 Bad Request).The answer is security. Security is an important feature for any application. ASP.NET try to his best to give you more secure application environment as possible. One important security feature is related to URLs. Because there are various ways a hacker can try to access server resource. Therefore it is important to make your application as secure as possible. Fortunately, ASP.NET provides this security by throwing an exception of Bad Request whenever he feels. In this Article I am try to present when ASP.NET feels to throw this exception. You will also see some new ASP.NET 4 features which gives developers some control on this situation.   Description:   http.sys Restrictions:           It is interesting to note that after deploying your application on windows server that runs IIS 6 or higher, the first receptionist of HTTP request is the kernel mode HTTP driver: http.sys. Therefore for completing your request successfully you need to present your validity to http.sys and must pass the http.sys restriction.           Every http request URL must not contain any character from ASCII range of 0x00 to 0x1F, because they are not printable. These characters are invalid because these are invalid URL characters as defined in RFC 2396 of the IETF. But a question may arise that how it is possible to send unprintable character. The answer is that when you send your request from your application in binary format.           Another restriction is on the size of the request. A request containg protocal, server name, headers, query string information and individual headers sent along with the request must not exceed 16KB. Also individual header should not exceed 16KB.           Any individual path segment (the portion of the URL that does not include protocol, server name, and query string, for example, http://a/b/c?d=e,  here the b and c are individual path) must not contain more than 260 characters. Also http.sys disallows URLs that have more than 255 path segments.           If any of the above rules are not follow then you will get 400 Bad Request Exception. The reason for this restriction is due to hack attacks against web servers involve encoding the URL with different character representations.           You can change the default behavior enforced by http.sys using some Registry switches present at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters    ASP.NET Restrictions:           After passing the restrictions enforced by the kernel mode http.sys then the request is handed off to IIS and then to ASP.NET engine and then again request has to pass some restriction from ASP.NET in order to complete it successfully.           ASP.NET only allows URL path lengths to 260 characters(only paths, for example http://a/b/c/d, here path is from a to d). This means that if you have long paths containing 261 characters then you will get the Bad Request exception. This is due to NTFS file-path limit.           Another restriction is that which characters can be used in URL path portion.You can use any characters except some characters because they are called invalid characters in path. Here are some of these invalid character in the path portion of a URL, <,>,*,%,&,:,\,?. For confirming this just right click on your Solution Explorer and Add New Folder and name this File to any of the above character, you will get the message. Files or folders cannot be empty strings nor they contain only '.' or have any of the following characters.....            For checking the above situation i have created a Web Application and put Default.aspx inside A%A folder (created from windows explorer), then navigate to, http://localhost:1234/A%25A/Default.aspx, what i get response from server is the Bad Request exception. The reason is that %25 is the % character which is invalid URL path character in ASP.NET. However you can use these characters in query string.           The reason for these restrictions are due to security, for example with the help of % you can double encode the URL path portion and : is used to get some specific resource from server.   New ASP.NET 4 Features:           It is worth to discuss the new ASP.NET 4 features that provides some control in the hand of developer. Previously we are restricted to 260 characters path length and restricted to not use some of characters, means these characters cannot become the part of the URL path segment.           You can configure maxRequestPathLength and maxQueryStringLength to allow longer or shorter paths and query strings. You can also customize set of invalid character using requestPathInvalidChars, under httpruntime element. This may be the good news for someone who needs to use some above character in their application which was invalid in previous versions. You can find further detail about new ASP.NET features about URL at here           Note that the above new ASP.NET settings will not effect http.sys. This means that you have pass the restriction of http.sys before ASP.NET ever come in to the action. Note also that previous restriction of http.sys is applied on individual path and maxRequestPathLength is applied on the complete path (the portion of the URL that does not include protocol, server name, and query string). For example, if URL is http://a/b/c/d?e=f, then maxRequestPathLength will takes, a/b/c/d, into account while http.sys will take a, b, c individually.   Summary:           Hopefully this will helps you to know how some of initial security features comes in to play, but i also recommend that you should read (at least first chapter called Initial Phases of a Web Request of) Professional ASP.NET 2.0 Security, Membership, and Role Management by Stefan Schackow. This is really a nice book.

• SQL Azure Reporting Limited CTP Arrived

  - by Shaun

  It’s about 3 months later when I registered the SQL Azure Reporting CTP on the Microsoft Connect after TechED 2010 China. Today when I checked my mailbox I found that the SQL Azure team had just accepted my request and sent the activation code over to me. So let’s have a look on the new SQL Azure Reporting.   Concept The SQL Azure Reporting provides cloud-based reporting as a service, built on SQL Server Reporting Services and SQL Azure technologies. Cloud-based reporting solutions such as SQL Azure Reporting provide many benefits, including rapid provisioning, cost-effective scalability, high availability, and reduced management overhead for report servers; and secure access, viewing, and management of reports. By using the SQL Azure Reporting service, we can do: Embed the Visual Studio Report Viewer ADO.NET Ajax control or Windows Form control to view the reports deployed on SQL Azure Reporting Service in our web or desktop application. Leverage the SQL Azure Reporting SOAP API to manage and retrieve the report content from any kinds of application. Use the SQL Azure Reporting Service Portal to navigate and view the reports deployed on the cloud. Since the SQL Azure Reporting was built based on the SQL Server 2008 R2 Reporting Service, we can use any tools we are familiar with, such as the SQL Server Integration Studio, Visual Studio Report Viewer. The SQL Azure Reporting Service runs as a remote SQL Server Reporting Service just on the cloud rather than on a server besides us.   Establish a New SQL Azure Reporting Let’s move to the windows azure deveploer portal and click the Reporting item from the left side navigation bar. If you don’t have the activation code you can click the Sign Up button to send a requirement to the Microsoft Connect. Since I already recieved the received code mail I clicked the Provision button. Then after agree the terms of the service I will select the subscription for where my SQL Azure Reporting CTP should be provisioned. In this case I selected my free Windows Azure Pass subscription. Then the final step, paste the activation code and enter the password of our SQL Azure Reporting Service. The user name of the SQL Azure Reporting will be generated by SQL Azure automatically. After a while the new SQL Azure Reporting Server will be shown on our developer portal. The Reporting Service URL and the user name will be shown as well. We can reset the password from the toolbar button.   Deploy Report to SQL Azure Reporting If you are familiar with SQL Server Reporting Service you will find this part will be very similar with what you know and what you did before. Firstly we open the SQL Server Business Intelligence Development Studio and create a new Report Server Project. Then we will create a shared data source where the report data will be retrieved from. This data source can be SQL Azure but we can use local SQL Server or other database if it opens the port up. In this case we use a SQL Azure database located in the same data center of our reporting service. In the Credentials tab page we entered the user name and password to this SQL Azure database. The SQL Azure Reporting CTP only available at the North US Data Center now so that the related SQL Server and hosted service might be better to select the same data center to avoid the external data transfer fee. Then we create a very simple report, just retrieve all records from a table named Members and have a table in the report to list them. In the data source selection step we choose the shared data source we created before, then enter the T-SQL to select all records from the Member table, then put all fields into the table columns. The report will be like this as following In order to deploy the report onto the SQL Azure Reporting Service we need to update the project property. Right click the project node from the solution explorer and select the property item. In the Target Server URL item we will specify the reporting server URL of our SQL Azure Reporting. We can go back to the developer portal and select the reporting node from the left side, then copy the Web Service URL and paste here. But notice that we need to append “/reportserver” after pasted. Then just click the Deploy menu item in the context menu of the project, the Visual Studio will compile the report and then upload to the reporting service accordingly. In this step we will be prompted to input the user name and password of our SQL Azure Reporting Service. We can get the user name from the developer portal, just next to the Web Service URL in the SQL Azure Reporting page. And the password is the one we specified when created the reporting service. After about one minute the report will be deployed succeed.   View the Report in Browser SQL Azure Reporting allows us to view the reports which deployed on the cloud from a standard browser. We copied the Web Service URL from the reporting service main page and appended “/reportserver” in HTTPS protocol then we will have the SQL Azure Reporting Service login page. After entered the user name and password of the SQL Azure Reporting Service we can see the directories and reports listed. Click the report will launch the Report Viewer to render the report.   View Report in a Web Role with the Report Viewer The ASP.NET and Windows Form Report Viewer works well with the SQL Azure Reporting Service as well. We can create a ASP.NET Web Role and added the Report Viewer control in the default page. What we need to change to the report viewer are Change the Processing Mode to Remote. Specify the Report Server URL under the Server Remote category to the URL of the SQL Azure Reporting Web Service URL with “/reportserver” appended. Specify the Report Path to the report which we want to display. The report name should NOT include the extension name. For example my report was in the SqlAzureReportingTest project and named MemberList.rdl then the report path should be /SqlAzureReportingTest/MemberList. And the next one is to specify the SQL Azure Reporting Credentials. We can use the following class to wrap the report server credential. 1: private class ReportServerCredentials : IReportServerCredentials 2: { 3: private string _userName; 4: private string _password; 5: private string _domain; 6:  7: public ReportServerCredentials(string userName, string password, string domain) 8: { 9: _userName = userName; 10: _password = password; 11: _domain = domain; 12: } 13:  14: public WindowsIdentity ImpersonationUser 15: { 16: get 17: { 18: return null; 19: } 20: } 21:  22: public ICredentials NetworkCredentials 23: { 24: get 25: { 26: return null; 27: } 28: } 29:  30: public bool GetFormsCredentials(out Cookie authCookie, out string user, out string password, out string authority) 31: { 32: authCookie = null; 33: user = _userName; 34: password = _password; 35: authority = _domain; 36: return true; 37: } 38: } And then in the Page_Load method, pass it to the report viewer. 1: protected void Page_Load(object sender, EventArgs e) 2: { 3: ReportViewer1.ServerReport.ReportServerCredentials = new ReportServerCredentials( 4: "<user name>", 5: "<password>", 6: "<sql azure reporting web service url>"); 7: } Finally deploy it to Windows Azure and enjoy the report.   Summary In this post I introduced the SQL Azure Reporting CTP which had just available. Likes other features in Windows Azure, the SQL Azure Reporting is very similar with the SQL Server Reporting. As you can see in this post we can use the existing and familiar tools to build and deploy the reports and display them on a website. But the SQL Azure Reporting is just in the CTP stage which means It is free. There’s no support for it. Only available at the North US Data Center. You can get more information about the SQL Azure Reporting CTP from the links following SQL Azure Reporting Limited CTP at MSDN SQL Azure Reporting Samples at TechNet Wiki You can download the solutions and the projects used in this post here.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Agile Awakenings and the Rules of Agile

  - by Robert May

  For those that care, you can read my history of management and technology to understand why I think I’m qualified to talk about this at all.  It’s boring, so feel free to skip it. Awakenings I first started to play around with the idea of “agile” in 2004 or 2005.  I found a book on the Rational Unified Process that I thought was good, and attempted to implement parts of it.  I thought I was agile, but really, it wasn’t.   I still didn’t understand the concept of a team.  I still wanted to tell the team what to do and how to get it done.  I still thought I was smarter than the team. After that job, I started work on another project and began helping that team.  The first few months were really rough.  We were implementing Scrum, which was relatively new to everyone on the team, and, quite frankly, I was doing a poor job of it.  I was trying to micro-manage every aspect of the teams work, and we were all miserable. The moment of change came when the senior architect bailed on the project.  His comment to me was: “This isn’t Agile.  Where are the stand-ups?  Where are the stories?”  He was dead on, and I finally woke up.  I finally realized that I was the problem!  I wasn’t trusting the team.  I wasn’t helping the team.  I was being a manager. Like many (most?), I was claiming to be Agile and use Scrum, but I wasn’t in fact following the rules Scrum.  Since then, I’ve done a lot of studying, hands on practice, coaching of many different teams, and other learning around Scrum, and I have discovered that Scrum has some rules that must be followed for success, even though the process is about continuous improvement. I’ve been practicing Scrum right for about 4 years now and have helped multiple teams implement it successfully, so what you’re about to get is based on experience, rather than just theory. The Rules of Scrum In my experience, what I’ve found is that most companies that claim to be doing Scrum or Agile are actually NOT doing either.  This stems largely because they think that they can “adopt the rules of Agile that fit their organization.”  Sadly, many of them think that this means they can adopt iterations (sprints) and not much else.  Either that, or they think they can do whatever they want, or were doing before, and call it Scrum.  This is simply not true. Here are some rules that must be followed for you to really be doing Scrum.  I’ll go into detail on each one of these posts in future blog posts and update links here.  My intent is that this will help other teams implementing scrum to see more success. Agile does not allow you to do whatever you want A Product Owner is required A ScrumMaster is required The team must function as a Team, and QA must be part of the team Support from upper management is required A prioritized product backlog is required A prioritized sprint backlog is required Release planning is required Complete spring planning is required Showcases are required Velocity must be measured Retrospectives are required Daily stand-ups are required Visibility is absolutely required For now, I think that’s enough, although I reserve the right to add more.  If you’re breaking any of these rules, you’re probably not doing Scrum.  There are exceptions to these rules, but until you have practiced Scrum for a while, you don’t know what those exceptions are. Breaking the Rules Many teams break these rules because they are the ones that expose the most pain.  Scrum is not Advil.  It’s not intended to mask the pain, its intended to cure it.  Let me explain that analogy a bit more.  Recently, my 7 year old son broke his arm, quite severely (see the X-Ray to the right).  That caused him a great deal of pain.  We went first to one doctor, and after viewing the X-Ray, they determined that there was no way that they’d cast the arm at their location.  It was simply too bad of a break for them to deal with.  They did, however, give him some Advil for the pain and put a splint on his arm to stabilize the broken bones.  Within minutes, he was feeling much better.  Had we been stupid, we could have gone home and he’d have been just as happy as ever . . . until the pain medication wore off or one of his siblings touched the splint.  Then, all of that pain would come right back to the top.  Sure, he could make it go away by just taking more Advil and moving the splint out of the way, but that wasn’t going to fix the problem permanently. We ended up in an emergency room with a doctor who could fix his arm.  However, we were warned that the fix was going to be VERY painful, and it was.  Even with heavy sedation (Propofol), my son was in enough pain that he squirmed and wiggled trying to get his arm away from the doctor.  He had to endure this pain in order to have a functional arm. But the setting wasn’t the end.  He had to have several casts, had to have it re-broken once, since the first setting didn’t take and finally was given a clean bill of health. Agile implementation is much like this story.  Agile was developed as a result of people recognizing that the development methodologies that were currently in place simply were ineffective.  However, the fix to the broken development that’s been festering for many years is not painless.  Many people start Agile thinking that things will be wonderful.  They won’t!  Agile is about visibility, and often, it brings great pain to surface.  It causes all of the missed deadlines, the cowboy coders, the coasters, the micro-managers, the lazy, and all of the other problems that are really part of your development process now to become painfully visible to EVERYONE.  Many people don’t like this exposure.  Agile will make the pain better, but not if you remove the cast (the rules above) prematurely and start breaking the rules that expose the most pain.  The healing will take time and is not instant (like Advil).  Figuring out what the true source of pain and fixing it is very valuable to you, your team, and your company.  Remember as you’re doing this that Agile isn’t the source of the pain, it’s really just exposing it.  Find the source. My recommendation is that ALL of these rules are followed for a minimum of six months, and preferably for an entire year, before you decide to break any of these rules.  Get a few good releases under your belt.  Figure out what your velocity is and start firing as a team.  Chances are, after you see agile really in action, you won’t want to break the rules because you’ll see their value. More Reading Jean Tabaka recently published a list of 78 Things I Have Learned in 6 Years of Agile Coaching.  Highly recommended. Technorati Tags: Agile,Scrum,Rules

• Remote Desktop to Your Azure Virtual Machine

  - by Shaun

  The Windows Azure Team had just published their new development portal this week and the SDK 1.3. Within this new release there are a lot of cool feature available. The one I’m looking forward to is Remote Desktop Access to your running Windows Azure Virtual Machine.   Configuration Remote Desktop Access It would be very simple to make the azure service enable the remote desktop access. First of all let’s create a new windows azure project from the Visual Studio. In this example I just created a normal MVC 2 web role without any modifications. Then we right-click the azure project node in the solution explorer window and select “Publish”. Then let’s select the “Deploy your Windows Azure project to Windows Azure” on the top radio button. And then select the credential, deployment service/slot, storage and label as susal. You must have the Management API Certificates uploaded to your Windows Azure account, and install the certification on you machine before in order to use this one-click deployment feature. If you are familiar with this dialog you will notice that there’s a linkage named “Configure Remote Desktop connections”. Here is where you need to make this service enable the remote desktop feature. After clicked this link we will set the configuration of the remote desktop access authorization information. There are 4 steps we need to do to configure our access. Certificates: We need either create or select a certificate file in order to encypt the access cerdenticals. In this example I will use the certificate file for my Management API. Username: The remote desktop user name to access the virtual machine. Password: The password for the access. Expiration: The access cerdentals would be expired after 1 month by default but we can amend here. After that we clicked the OK button to back to the publish dialog.   The next step is to back to the new windows azure portal and navigate to the hosted services list. I created a new hosted service and upload the certificate file onto this service. The user name and password access to the azure machine must be encrypted from the local machine, and then send to the windows azure platform, then decrypted on the azure side by the same file. This is why we need to upload the certificate file onto azure. We navigated to the “Hosted Services, Storage Accounts & CDN"” from the left panel and created a new hosted service named “SDK13” and selected the “Certificates” node. Then we clicked the “Add Certificates” button. Then we select the local certificate file and the password to install it into this azure service.   The final step would be back to our Visual Studio and in the pulish dialog just click the OK button. The Visual Studio will upload our package and the configuration into our service with the remote desktop settings.   Remote Desktop Access to Azure Virtual Machine All things had been done, let’s have a look back on the Windows Azure Development Portal. If I selected the web role that I had just published we can see on the toolbar there’s a section named “Remote Access”. In this section the Enable checkbox had been checked which means this role has the Remote Desktop Access feature enabled. If we want to modify the access cerdentals we can simply click the Configure button. Then we can update the user name, password, certificates and the expiration date.   Let’s select the instance node under the web role. In this case I just created one instance for demo. We can see that when we selected the instance node, the Connect button turned enabled. After clicked this button there will be a RDP file downloaded. This is a Remote Desctop configuration file that we can use to access to our azure virtual machine. Let’s download it to our local machine and execute. We input the user name and password we specified when we published our application to azure and then click OK. There might be some certificates warning dislog appeared. This is because the certificates we use to encryption is not signed by a trusted provider. Just select OK in these cases as we know the certificate is safty to us. Finally, the virtual machine of Windows Azure appeared.   A Quick Look into the Azure Virtual Machine Let’s just have a very quick look into our virtual machine. There are 3 disks available for us: C, D and E. Disk C: Store the local resource, diagnosis information, etc. Disk D: System disk which contains the OS, IIS, .NET Frameworks, etc. Disk E: Sotre our application code. The IIS which hosting our webiste on Azure. The IP configuration of the azure virtual machine.   Summary In this post I covered one of the new feature of the Azure SDK 1.3 – Remote Desktop Access. We can set the access per service and all of the instances of this service could be accessed through the remote desktop tool. With this feature we can deep into the virtual machines of our instances to see the inner information such as the system event, IIS log, system information, etc. But we should pay attention to modify the system settings. 2 reasons from what I know for now: 1. If we have more than one instances against our service we should ensure that all system settings we modifed are applied to all instances/virtual machines. Otherwise, as the machines are under the azure load balance proxy our application process may doesn’t work due to the defferent settings between the instances. 2. When the virtual machine encounted some problem and need to be translated to another physical machine all settings we made would be disappeared.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.
