• Change Laptop Wireless Card?

  - by Craig

  I have just bought a new Samsung RV511 Laptop (the i5 Version). Anyway it comes installed with a Broadcom Wifi Card, I have a Super Atheros Mini Wifi Card that I would like to swap for the Broadcom one. I use Atheros for security auditing purposes in Linux that the Broadcom one is not good for. Trouble is I have never got to the barebones of a laptop, although I am a Custom PC Builder, laptops i generally have no concern for. Take a look at this picture, I took one back panel off to reveal some of the components: I believe the Wireless Card is where I marked the arrow pointing too. That little white square thing appears to be a sticker of the Wifi card, it says WLAN. How can I access it to swap it with my Atheros one. Do I need to remove all the outermost screws? There are screws located to the right of where I scribbled in Yellow and next to the HDD, do I just remove those? I dont want to destroy the machine, only just got it today. Appreciate some help thanks.

• Durability of Websockets Server

  - by smitchell360

  I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for.

• Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx)

  - by Finglish

  Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx) I am attempting to use nginx to serve private files from django. For X-Access-Redirect settings I followed the following guide http://www.chicagodjango.com/blog/permission-based-file-serving/ Here is my site config file (/etc/nginx/site-available/sitename): server { listen 80; listen 443 default_server ssl; server_name localhost; client_max_body_size 50M; ssl_certificate /home/user/site.crt; ssl_certificate_key /home/user/site.key; access_log /home/user/nginx/access.log; error_log /home/user/nginx/error.log; location / { access_log /home/user/gunicorn/access.log; error_log /home/user/gunicorn/error.log; alias /path_to/app; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_pass http://127.0.0.1:8000; proxy_connect_timeout 100s; proxy_send_timeout 100s; proxy_read_timeout 100s; } location /protected/ { internal; alias /home/user/protected; } } I then tried using the following in my django view to test the download: response = HttpResponse() response['Content-Type'] = "application/zip" response['X-Accel-Redirect'] = '/protected/test.zip' return response but instead of the file download I get: 403 Forbidden nginx/1.1.19 Please note: I have removed all the personal data from the the config file, so if there are any obvious mistakes not related to my error that is probably why. My nginx error log gives me the following: 2012/09/18 13:44:36 [error] 23705#0: *44 directory index of "/home/user/protected/" is forbidden, client: 80.221.147.225, server: localhost, request: "GET /icbdazzled/tmpdir/ HTTP/1.1", host: "www.icb.fi"

• Prevent Win7 from resuming from hibernation

  - by Tigraine

  Hi Guys, I am running Win7 x64 on my machine and everything is perfect. I actually never turn off my PC completely but rather I always put it into hibernation mode for fast resume once I get back. Hibernation works like a charm, but once every 50 or 100 hibernations something goes wrong and the machine reboots. After that I usually have to reset the system clock in BIOS and Windows is starting up from the hibernation image that somehow got saved to disk (that's really cool). But: This hibernation image recovery is awfully slow, once the machine is up again it takes almost 2 minutes for it to not feel sluggish any more (I suspect this is due to pagefaults on all memory access). I'm looking for a way to tell Windows to NOT recover from the crash but rather just boot fresh, discarding the hibernation since it's faster to just reboot rather than wait for 3+ minutes for the machine to get it's act together. I do see the normal bios startup and also the windows boot afterwards, but hitting F8 like crazy doesn't do anything. In Win2000 and XP a Menu would come up asking me how I do want to boot, but I can't find it on Win7. Thanks in advance!

• Fresh Install of SQL Server 2008 doesn't install managment studio. Help!

  - by Jordan S

  Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do?

• OSX 10.6 goes unresponsive

  - by mjb

  This behavior continues to perplex me. My MBP, running 10.6.7, stops responding to all Apple-based software. Whatever software I have open remains open (Terminal, iTunes, Safari), but if I try to use the F-shortcuts or launch any OSX-based software not already open (System Preferences for example) it just bounces in the dock then never launches. I also cannot reboot without hard rebooting. I left terminal open, so I see the following in /var/log/system.log Jun 25 19:39:02 mjb-2 com.apple.ReportCrash.Root[59432]: 2011-06-25 19:39:02.585 ReportCrash[59432:7f1f] Saved crash report for CoreServicesUIAgent[59576] version ???

• RoboCopy errors on Windows Server 2008

  - by Steve

  I am getting bizarre error with RoboCopy in Server 2008. It will randomly hang with "The specified network name is no longer available." error. Once that happens, it will continue to fail on the retries. But of course the remote server IS still available on the network and can be reached with other tools. I think it must be somehow permission related but I can't figure out what is wrong. Any ideas would be much appreciated. Other info: Options : *.* /S /E /COPY:DAT /NP /R:10 /W:30 If I turn on the /B option it will fail 100% of the time at the very beginning (that's why I think it has to be somehow permission-related) The two servers are standalone and I am doing a NET USE command prior to the robocopy It does not matter what user account on the remote server. Tried both Administrator and another user which was also a member of the local Administrators group UAC is turned off on both sides It is not always the same file that hangs. Sometimes it will get through half or more and sometimes it will fail on the first file

• Apache2.2 not responding on Windows 7 desktop

  - by Adam

  Afternoon! I'm having some trouble with Apache2.2 on Windows 7. For over a year it's been running no problem, but all of a sudden requests have just stopped responding. They don't ever time out, the browser just keeps on waiting for a response, which makes me think it's something blocking communication with Apache. Interestingly though, if I stop Apache the requests fail immediately. The Apache service is running, and using netstat I can see it listening on port 80 as configured: TCP 127.0.0.1:80 0.0.0.0:0 LISTENING If I stop the Apache service, that line disappears. I have an entry within my hosts file for each VHost I'm trying, all pointing to 127.0.0.1. Each VHost is configured to *:80. Nothing however is getting recorded in the access or error (at debug level) log files. I've verified the file paths are correct, even though they were never changed. Neither is anything getting recorded within Windows' Event Log. The problem showed up when I added a new VHost and restarted, however I hadn't been using it for a couple of days prior so I don't believe it's the config change. I have performed a syntax check to be sure, and when starting from the command prompt no errors are reported there. I do have Windows Firewall running, however I've verified the Apache rule is correct and tried turning it off to ensure that wasn't the problem. I've reinstalled Apache, in the hope it might magically fix something using the default config, but still no joy. I've also tried using a different port. I'm completely lost for ideas now. Can anybody help? Cheers Adam

• Can grub and BCD work simultaneously?

  - by wuputah

  Here's my setup. After I installed a new SSD, I have: Original Windows 7 on sdc1 (to be retired) Copy of Windows 7 on sdb2 A Windows system partition on sdb1 Ubuntu 12.04 on sda, /boot and ergo grub is on sda1 Grub is MBR on sda and set to boot from BIOS. I prefer to not change this; grub is much preferable as a boot manager. I've run update-grub from Ubuntu and grub seems to be correctly configured as all options are available: I can boot any of the 3 Windows partitions and Ubuntu. I also ran the repair tool to get Windows to add both installations to BCD. At present, choosing particular options seem to have no effect; the old version of Windows on sdc1 always boots. I don't understand what is causing this, but I can't figure out what. How does grub and BCD play along? I can't find any docs on this. My thought was to only boot Windows off sdb1, and then let BCD do the rest (present a menu to boot between sdb2 and sdc1, but I can't seem to get BCD to boot sdb2), but this has been unsuccessful. My configuration files: BCDEdit output grub.cfg

• Simple options for port forwarding to a different port?

  - by Nick

  I have three network printers at our local office, all of which listen on port 9100. Non of them offer the option of changing the listening port. We have a single public static IP address, and access to our main network is through a Linksys WRT-54G. We need to be able to print to these printers from outside the office. The problem is, with the 54G, I can only forward a port to the SAME port on a particular IP address. What I really need though is a way to forward to an ip address and a DIFFERENT port. I need to do this: In port Destination 9100 192.168.1.1 : 9100 9101 192.168.1.2 : 9100 9102 192.168.1.3 : 9100 So I'm looking for options. I could setup an old computer with two network cards and IPtables I suppose, but that seems like a lot of overhead for something relatively simple. Is there a way a virtual machine (read: one network card) could do the advanced port forwarding? Where I forward all traffic to it, and it forwards it on to the right printer? Or what about those mini Linux distros that replace the WRT-54G's firmware? Do any of those support what I need "out of the box"? I have a spare WRT- could I make it an IP tables router? Recommendations for mini distros? Or is there an off-the-shelf product that does this (cheap/local preferred)? Any advice / options appreciated. Thanks!

• Active Directory Child Domain Replication Problems

  - by MikeR

  Hi, I've recently inherited an Active Directory (all DCs Windows 2003) which has been configured with several child domains that are used as test environments for out CRM software. Two of these child domains have been used for testing using dates in the future (2015), throwing them well outside of the Kerberos tolerance for time, and they're flooding my event logs with replication errors such as the following: Description: The attempt to establish a replication link for the following writable directory partition failed. Directory partition: CN=Schema,CN=Configuration,DC=ad,DC=xxxxxxx,DC=com Source domain controller: CN=NTDS Settings,CN=TESTDC001,CN=Servers,CN=SiteName,CN=Sites,CN=Configuration,DC=ad,DC=xxxxxxx,DC=com Source domain controller address: 38e95b2a-35af-4174-84ba-9ab039528cce._msdcs.ad.xxxxxxx.com Intersite transport (if any): This domain controller will be unable to replicate with the source domain controller until this problem is corrected. User Action Verify if the source domain controller is accessible or network connectivity is available. Additional Data Error value: 5 Access is denied. I'd also like to upgrade to Windows 2008 at some point, but wouldn't want to attempt any schema updates while I'm not 100% confident on the replication. I'm guessing my only real solution will be to get rid of these child domains. The child domains are operating as stand alone domains, the DC is up and running and authenticating test users fine. I'm guessing the best solution to this would be to delete the domains (although I'd be happily told otherwise). The clock forwarding appears to have been happening for several years, so I'm assuming I can't just put the clock right (I'm guessing scope for this would be 180days, the same as the tombstone lifetime) With the replication errors would I be able to dcpromo the child domains DC, select it as the last domain controller in the domain and the child domain would be deleted? Or would I be better off treating the domain as an orphaned domain and use Microsoft's instructions to clear up as such. Any advice would be much appreciated.

• VirtualBox: Can't get Bridged Networking to work (Win7 host)

  - by MikeTheTall

  I'm trying to set up a virtual LAMP server, including sharing files between the guest OS (Ubuntu Server) and the host OS (Windows 7) using samba. I think my problem is that I can't get Bridged (or Host-Only) networking to work in VirtualBox. I can boot the Linux VM just fine with NAT, but then can't access any services on it directly (except after port-forwarding port 80)(my understanding is that port-forwarding works because I'm not running a web server on the host OS, and therefore it can forward traffic to the unused port 80). I don't think that port-forwarding samba traffic (from the host to the guest) will work since I think that the host OS is using those ports. When I turn off NAT and turn bridged networking on I get an error. The VM fails to boot, with a dialog popping up (title: VirtualBox - Error) that says "Failed to open a session for the virtual machine UbuntuServer. Configuration error: Failed to get MAC address (VERR_CFGM_VALUE_NOT_FOUND). I'm hoping that once this is resolved then samba will work ok :) Any advice on this would be great (how to fix it would be wonderful, next steps for troubleshooting would be great, too :) )

• Slow boot for OS and external devices

  - by Derek Van Cuyk

  I have been having this problem intermittently but as of yesterday, it has become more consistent. It originally started when I rebooted my PC at home and the OS (Windows 8) sat in a loop appearing to do nothing while loading. I figured since this was a new installation, that something may have just become corrupted and I decided to reinstall. So I tried to boot off of the thumb drive which had the installation iso and encountered pretty much the same issue. Same with the DVD drive. So, I rebooted once again and left it to load the entire night just to see if it ever would and sure enough this morning, Windows had finally loaded. Authentication had the same roblem albeit not quite as long (took about 5 minutes to authenticate). However, once I was in, everything appeared to be working fine and as quick as normal with the exception of when I tried to scan the C drive for any errors, which ran unbearably slow (45 minutes and before I left for work and was not finished scanning a 64GB SSD drive). I mention that I have had this issue but never when loading the OS. Before it occurred when trying to install windows 7 from a different DVD drive than the one I have now. It took me about 3 hours to do it since I had to wait sometimes 30+ min for each step to finish processing. Does anyone have an idea as to what can cause this? I am assuming it is the motherboard since it is responsible for communication with all the devices I'm having issues with but I cannot find anyone else who has had a problem like this and don't want to drop more money on a MB if it isn't the problem. Hardware: Motherboard: Asus M4A78T-E Socket AM3/ AMD 790GX/ Hybrid CrossFireX Hard Drive: Kingston SSDNow V+180 64GB Micro SATA II 3GB/S 1.8 Inch Solid State Drive SVP180S2/64G Optical Drive: Samsung Blu-Ray Combo Internal 12XReadable and DVD-Writable Drive with Lightscribe SH-B123L/BSBP Thanks, Derek

• Add and remove letterhead in Word document

  - by Daniel Wolf

  Our company has letterheaded paper (pre-printed paper with our logo on it). Whenever we send something out by mail, we print it on that paper. However, when we send the same document via email, we convert it to a PDF file. Now the problem is: when converting a Word document to PDF, it should contain the letterhead. When printing the same document on paper, it should not (or else the letterhead would be printed twice). Currently, we are using two different Word document templates - one with letterhead, one without. So whenever we want to add or remove the letterhead, we have to create a new document with the other template and copy and paste everything over. Nasty solution. What I'm looking for is some simple way to switch the letterhead on and off. What I've tried so far: Switching the template: There does not seem to be a simple way to switch the template for an existing document. Using a picture watermark: Our letterhead goes all the way to the border of the page. (No printer supports this, of course, but it is fine for export to PDF.) Apparently depending on the current default printer, Word will not allow a borderless watermark, instead shifting the image around. Using the page header: When editing the page header, I can insert pictures at arbitrary positions, which is great. However, I could not find a way (short of macros) to enable/disable just the pictures in the header. (The text should remain there.)

• Local DNS and Apache Server Configuration Interferring - example.com / www.example.com

  - by nicorellius

  I have a domain for my site: example.com I am also running local DNS with these lines: www IN CNAME server.<host_provider>.com. dev IN CNAME server.<host_provider>.com. So www.example.com and dev.example.com go to production and development sites, respectively, that are hosted by a host company. In my Apache configuration for the main site, I'm running a rewrite rule like this: RewriteEngine ON RewriteCond %{HTTP_HOST} ^example\.com$|!dev\.example\.com$ [NC] RewriteRule ^(.*)$ http://www\.%{HTTP_HOST}/$1 [R=302,L,NE] This rule seems to work, as when you are off the network and go to example.com in the browser, you get redirected to www.example.com. The problem is when I'm on the network, and I go to example.com I get an error page, saying page can't be found. No server errors; just a page can't be found, as if the local DNS is causing it to stop looking at that point. I'm also using Nettica for DNS service and have this A record in place: example.com Host (A) Default xxx.xx.xxx.xx This handles the external DNS, but my problem seems to be related to my internal DNS. For example, inside my network, I can go to servers on the network with addresses like this: server.example.com server1.example.com server2.example.com These are configured in my local DNS. I'm just not sure how to get past the "empty" subdomain and go to example.com. Adding to this since it might not be clear. If I'm out side the example.com network, on another network, like example123.com, then when I go to example.com I'm redirected to www.example.com as expected, eg, the Apache rewrite rule is working. Thanks in advance for any information.

• How do I remove a USB drive's write protection?

  - by nate

  I have a SanDisk Cruser Blade USB stick that suddenly seems to be write protected. I tried running DiskPart but after I write the command "attributes disk clear readonly" it displays this: Microsoft DiskPart version 5.1.3565 ADD - Add a mirror to a simple volume. ACTIVE - Marks the current basic partition as an active boot partition. ASSIGN - Assign a drive letter or mount point to the selected volume. BREAK - Break a mirror set. CLEAN - Clear the configuration information, or all information, off the disk. CONVERT - Converts between different disk formats. CREATE - Create a volume or partition. DELETE - Delete an object. DETAIL - Provide details about an object. EXIT - Exit DiskPart EXTEND - Extend a volume. HELP - Prints a list of commands. IMPORT - Imports a disk group. LIST - Prints out a list of objects. INACTIVE - Marks the current basic partition as an inactive partition. ONLINE - Online a disk that is currently marked as offline. REM - Does nothing. Used to comment scripts. REMOVE - Remove a drive letter or mount point assignment. REPAIR - Repair a RAID-5 volume. RESCAN - Rescan the computer looking for disks and volumes. RETAIN - Place a retainer partition under a simple volume. SELECT - Move the focus to an object. It's like when you type help at the DiskPart prompt, so how do I get past this? This problem started when I plugged the stick into a laptop which had viruses, if that's any help.

• Apache MaxClients doubt

  - by Milan Babuškov

  I have a busy Apache server serving only dynamic PHP+MySQL pages. It is a prefork Apache, version 2.2.4 with following config: KeepAlive off StartServers 8 MinSpareServers 32 MaxSpareServers 64 ServerLimit 512 MaxClients 512 MaxRequestsPerChild 4000 MaxClients/ServerLimit used to be set to 256, but I got the following error in error_log so I increased it: [error] server reached MaxClients setting, consider raising the MaxClients setting It seems to work now, but I have a doubt. Looking at MySQL log of queries, I have a couple hundred clients per seconds, but "ps ax" only shows 8, 9 or 10 processes running: [root@engine ~]# ps ax | grep http | wc -l 10 I even got this many processes when the above error message was shown in error_log. This made me investigate further. When I run netstat -a, I get something like this: tcp 0 0 engine:http adsl-105-143.teol.net:21453 TIME_WAIT tcp 0 0 engine:http 118-36.static.kds:mck-ivpip TIME_WAIT tcp 0 0 engine:http 118-36.static:oce-snmp-trap TIME_WAIT tcp 0 0 engine:http 118-36.static.kd:unifyadmin TIME_WAIT tcp 0 0 engine:http cable-188-2-25-29.dyna:4906 TIME_WAIT tcp 0 0 engine:http adsl-105-143.teol.net:21458 TIME_WAIT tcp 0 0 engine:http 109-92-83-91.dynamic.:62821 TIME_WAIT tcp 0 0 engine:http cable-89-216-142-192.:63576 TIME_WAIT tcp 0 0 engine:http 109-92-83-91.dynamic.:62819 TIME_WAIT tcp 1081 0 engine:http pttnetadsl38-36.ptt.r:50496 ESTABLISHED tcp 0 0 engine:http cable-188-2-36-196.dyn:4136 TIME_WAIT tcp 0 0 engine:http cable-89-216-142-192.:63580 TIME_WAIT tcp 0 0 engine:http cable-89-216-142-192.:63581 TIME_WAIT etc. When counting those, I get: [root@engine ~]# netstat -a | grep http | wc -l 431 Can anyone tell me what is really going on here and how to make sure my server keeps working, because I only use 50% of available RAM in machine?

• PHP memory_limit local value does not match php.ini value

  - by Buttle Butkus

  CentOS system. Summary: changed memory_limit in master and local php.ini and yet no change in the local value for a particular virtual host. Trying to improve performance, I set the memory_limit to 1024M in /etc/php.ini phpinfo() shows Master and Local values for other virtual hosts on the server as 1024M. Changing the value in /etc/php.ini changes all values, except one. One site is stuck with a local value of 256M. I thought I found the problem: there is a php.ini file (which I didn't know about) in that site's root, and it had memory_limit = 256M I changed it to 1024M. Problem solved? No. And now I don't know where to look. Obviously, I've restarted apache (/etc/init.d/httpd restart), and that usually does the trick. I also turned off APC cache, though I don't think it would cache ini files. And finally, I tried adding this to the virtual host in httpd.conf: php_value memory_limit 536870912 (yes, that would be 5 GB) And that had no effect whatsoever. What else could be the problem? Thanks.

• IIS6 Virtual SMTP server isn't coming back up automatically after a system restart

  - by Julian James

  I've got a virtual server running Win2008 RC2. I've set up IIS6 with a virtual SMTP server on it to be the mail provider for the websites I'm hosting there. It all works great, but if for some reason the server reboots (auto updates are still enabled - I'm trying to make this as little work as possible as we've got a Lot of clients), the IIS6 doesn't restart the SMTP server. The failure causes 500 errors on the current setup, so I'm spending half the day apologising. Any ideas? In Services I've set everything to come back up automatically, but still no dice. As soon as I restart the SMTP, no problems, all the mail gets sent. It's working perfectly, it just won't restart on it's own. I'd really rather not turn auto updates off as we're such a small company I just can't spare the time to be manually updating 15 copies of windows every time MS decide there's a security patch. All advice appreciated! BTW, I am a complete newb to these forums. I searched but couldn't find an answer, so please be nice. But firm. I've got to learn here.

• How to bypass vpn talking to VMWare Guest?

  - by marc esher

  Greetings. Network/VPN n00b question here. I'm running VMWare Workstation with a Guest Windows 2003 Server. It has SQL Server 2000 installed. The sole purpose for this Guest is to house SQL Server... it needn't have internet access or access to any other resources on the network other than the host. When launch Check Point VPN software, the host routes through the company network before it connects to the guest ... i.e. it's no longer a direct connection. I assume this is just how things are supposed to work. However, what's happening is that the connection between my host and the SQL Server instance on the guest intermittently drops. It's not consistent, and some databases on the server will be responsive while others aren't. It appears that the databases with the most traffic on the guest (the ones I'm hitting with load tests) are the ones that become intermittently unresponsive. This problem only manifests when VPN is on; when it's off, I can pound away on this database with no troubles. Thanks for any advice!

• Philips Monitor problems - vertical lines on screen

  - by asdasd

  I have an old CRT Philips Monitor 17'' and it was working well. There were problems with the electrical power and the monitor started to make some sound and a smoke was getting out of it. I quickly switched it off the power, and in the morning when the power was ok i started the monitor and it appeared to be working and it worked for a couple of minutes when i find out some smell was coming from it, and after 5 minutes the screen i was working shut down and on the monitor some vertical lines appeared - and nothing else. I thought it was the OS, so i rebooted the pc and while it was booting i realized the monitor didn't show the bios info etc, but the same vertical lines on the whole screen were on it, sometimes their color was changing and they were blinking, but no screen appeared - only those vertical lines. After a day, the monitor was ok again - i turned it on and no there were no lines, everything was working fine. The same for the next 2 days. My question is: If anyone had ever had the same problem, can you help me ? THe monitor may be ok now but i am afraid it can get back those lines again. I don't know what to do, if you know please tell me whether should i take it to the service or not. Thank you.

• With no password expire notification at logon in Windows 7, how are you configuring password expire

  - by J. L.

  To my understanding, Windows 7 users do not receive password expiration notification during the logon process - it occurs strictly from the system tray. We currently have tray balloon notifications disabled to lessen user distraction, and I expect the password change process is a smoother one during the logon process rather than in an existing session. As a result, users will get prompted to change their passwords at expiration. The users also connect to Terminal Services boxes, but receive the advanced notification for password expiration there. So, Windows 7 is not notifying, but TS/RDS and XP boxes are. Any guidance on configuring this? Personally, I would turn off all expiration notices, but I understand most users would prefer to see the notification. Thoughts? Any GPO or other settings I might be overlooking? The interactive logon setting below is already enabled for our Win7 workstation GPO. My thought is balloon notifications will get turned back on for Windows 7, but I wanted to see if anyone was aware of alternatives. Thanks.

• How do hdparm's -S and -B options interact?

  - by user697683

  These two options seem confusing. For example: according to the man page -B 254 "does not permit spin-down". However, testing with -B 254 -S 1 the drive does spin down after 5 seconds. -B Query/set Advanced Power Management feature, if the drive supports it. A low value means aggressive power management and a high value means better performance. Possible settings range from values 1 through 127 (which permit spin-down), and values 128 through 254 (which do not permit spin-down). The highest degree of power management is attained with a setting of 1, and the highest I/O performance with a setting of 254. A value of 255 tells hdparm to disable Advanced Power Management altogether on the drive (not all drives support disabling it, but most do). -S Put the drive into idle (low-power) mode, and also set the standby (spindown) timeout for the drive. This timeout value is used by the drive to determine how long to wait (with no disk activity) before turning off the spindle motor to save power. Under such circumstances, the drive may take as long as 30 seconds to respond to a subsequent disk access, though most drives are much quicker. The encoding of the timeout value is somewhat peculiar. A value of zero means "timeouts are disabled": the device will not automatically enter standby mode. Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes. A value of 253 sets a vendor-defined timeout period between 8 and 12 hours, and the value 254 is reserved. 255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives may have very different interpretations of these values.

• simple apache2 reverse proxy setup not working

  - by Nick

  I know what proxy is (very high level), it's just I have never set up one, and it feels like I might be missing some big fat point here. My setup: client server (static IP), runs apache on port 80 proxy (has 2 network cards, one is on the clients network, the other one with a static IP on the server network), runs apache on port 80 I am trying to configure these three machines so that when client requests: http://proxy/machine1 It gets served server's pages at server root URL, i.e. http://server/ I can access client pages just fine. However, when I try accessing a page from the client machine, it simply gets redirected to server's IP address, which it clearly can't access since they are not on the same network: ... <meta http-equiv="REFRESH" content="0;url=http://server/machine1"></meta> <title>Redirect</title> ... My apache2 config is: LoadModule proxy_module /modules/mod_proxy.so LoadModule proxy_http_module /modules/mod_proxy_http.so ProxyRequests off <Proxy *> Order Allow,Deny Allow from all </Proxy> ProxyPass /machine1 http://server:80 <Location /machine1> ProxyPassReverse / </Location> What gives? Thanks!
