• VirtualBox - Continuous Integration with Secure virtual server

  - by stacker

  I have a repository on the host machine that I need to expose to the virtual machine but not the the other world (even other computers on the router). On the virtual machine I have a deployed web application that I need to be exposed to my host only. Is that can be achievable?

• Reconciling vmware memory vs windows memory usage

  - by RyanW

  I have a Windows 2008 R2 64 bit virtual machine on ESXi 4.1 host. The host reports that the virtual machine is actively using less than 1 GB of memory. But, in Windows it's reporting the machine is using 7 GB of memory, even though the total of the processes listed in task manager is less than 1 GB. The machine is rather unresponsive and I'm concerned this is impacting other applications (server's purpose is to run ASP.NET state server process, which has been having trouble and led me to spot the memory question). I just noticed High memory usage Windows Server 2008r2 on VMware and will be looking through those documents more, but what is causing this?

• Virsh: Different XML with edit than dumpxml. Why?

  - by Dave Vogt

  I'm trying to fetch the VNC access data from a virtual machine managed by libVirt. However, when I run virsh dumpxml $machine, the vnc passwd is missing: <graphics type='vnc' port='-1' autoport='yes'/> Checking the same using virsh edit $machine, I see the password is actually there: <graphics type='vnc' port='-1' autoport='yes' passwd='asdf'/> Why is this? Is this intentional (what reason?), or could this be a bug?

• Can't ping guest OS from Windows XP SP3 host running VIC.

  - by Vittal

  Hi, I am running VMware ESX Server 3i Version 3.5.0 and accessing this server using VMware Infrastructure Client Version 2.5.0 on a Windows XP SP3 machine. I have enabled the Microsoft TCP/IP version 6 stack and assigned an IPv6 address (using the netsh command) to the network adapter. The guest OS'es running on ESX Server (includes Win7, W2K8, WinXP) also have IPv6 addresses enabled on their adapters. The adapters are configured to be in VM Network (Bridged mode) and hence have connectivity to the Internet. The VMs are able to ping each other using IPv6 addresses and are also able to ping a physical Win7 machine using IPv6 addresses. However, the Windows XP SP3 machine on which the Client is running is not able to ping any hosts running on ESX Server while the VMs are able to ping this host. Whenever I try to ping from WXP box I get the "Invalid source route specified." error. The WinXP machine is not able to ping the Win7 physical machine too (the same error as above is thrown). Can someone help me understand why I am receiving this error and what I need to do to resolve this error? Thanks, Vittal

• Why does not my Windows XP connects to the wireless?

  - by Amitabh

  I have a dell machine with Windows XP. For the past two days its not connecting to the wireless network. I have another machine with Windows 7 and its connects with the same wireless. This started happening since yesterday when I found a Virus (spy-agent.bw.gen!mem) on my machine which I think I managed to remove using Avira.

• About the External Graphics Card and CPU usage

  - by Balaji

  Hi, We are Rendering 16 live Streams at our client machine through one of our applications and the resolution of the video streams are as 4CIF/MPEG4/25FPS/4000Kbits. The configuration fo the client machine is below. HP Desktop Machine: Microsoft Windows XP Intel (R) Core2 Duo CPU E8400 @ 3.00 GHz 2.99 GHz, 1.94 GB of RAM Intel (R) Q45/Q43 Series Express Chipset (Inbuild) The CPU usage of the machine peaks 99% for 16 straems. After some discussion, we had decided to install external graphics card to reduce the CPU usage. So that, we have tried following graphics cards. NVIDIA Quadro NVS 440 - 128 MB Radeon HD 4350 - 512 MB GDDR2 Redeon HD 4350 - 1GB DDR2 ASUS EAH 4350 Silent 1GB DDR2 But the performance wise no difference, even worst. So, what is the pupuse of these external graphics cards? Really it will reduce the CPU usage? What parameters have to check, if we want to reduce the CPU usage? Please do the needful as soon as possible. Regards Balaji

• How do I access my samba drive through several layers of network topology?

  - by stephenmm

  I have a new windows 7 Home Premium machine that is in a different room than my main computer area. As such I have to use a bridge and another router. Everything is working wonderfully except I cannot access the SAMBA drive with the new machine. I know that SAMBA is accessible as an older WinXP machine can access it. A picture of my network would probably be helpfull: To ISP | | +---------------------------+ | WAN | | Cable Modem | | (2WIRE678) | | | | | +---------------------------+ | +---------------------------+ | | (|) (|) +-----------+ | Belkin Router | | | | Wireless | | (F5D) |--+ +--| WinXP | | | |SAMBA USER | | | +-----------+ +---------------------------+ | | | | +------------+ | | Ubuntu | | | Apache + | | |SAMBA Server| | +------------+ | | +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ # # +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ | +---------------------------+ | | | D-Link Router | | (DI-524) | | | | | +---------------------------+ | | | | +-----------+ | | | Win7 | |SAMBA USER?| +-----------+ More interesting data points: 1. I can ping the SAMBA server from the Win7 machine locally (Ie. 192.168.2.2) 2. I can access the webserver from the Win7 machine locally (Ie. 192.168.2.2) 3. I followed the advice to get Win7 and SAMBA to play nice: http://www.tannerwilliamson.com/2009/09/windows-7-seven-network-file-sharing-fix-samba-smb/ Sorry for being so long winded but it is kind of complex and I am really at a loss as to how to fix it. If any of you have some suggestions I would love to hear it!

• Tab Completion In Emacs shell-mode SSH Sessions

  - by Sean M

  My current use pattern of emacs results in my having several shell-mode buffers open, each running an ssh session. I am running into an issue with this, though - when I try to tab-complete file names and other things in my remote session, the shell attempts to use completions available on the local machine instead of on the remote machine. For example, if the file ~/foobar exists on the local machine and ~/frob exists on the remote machine, typing in ~/f and pressing tab results in ~/foobar instead of completing correctly. If I use ssh outside of emacs and try the same thing, I get the correct completion of ~/frob instead. How can I get tab-completion to complete the way it does in normal ssh sessions ?

• Hard Drive that was used before not detected or accessible in Windows 7

  - by Anders

  Hello SU: My PC crashed for some unknown reason, and I am still working on what caused that. However, I pulled my main (windows) drive from my computer and hooked it up to my roommate's machine and was able to pull the data I needed off of it (i.e. the drive is good). I hook up his drives as they were, I had to turn off his machine and unplug his secondary drive to hook mine up, boot his machine and there is no second drive available in windows explorer. I opened Device Manager to see if for some reason it's drive letter got un-assigned, but there is nothing listed in there except his primary hard drive, his optical drive and one other optical drive which I believe is the virtual drive Daemon Tools made. The drive shows up in the BIOS, however after I restarted his machine again it sits on the "Entering setup....." screen at the load window. The only thing I can think of is that may have messed with stuff is I used this tutorial to create a bootable XP install on a USB drive to install XP on my machine (I am 99% certain that the optical drive in my PC is broken) and maybe it used the other hard drive's letter for the USB drive for some reason, which doesn't make much sense since it was recognized it as a different drive letter before I started the process. It is possible that it used the secondary hard drive's letter for it's work, but once again I am uncertain. Where should I go from here? He his bound to wake up within the next several hours and will probably flip a lid if I cannot get some sort of handle on this. Any and all help is greatly appreciated. PS: Anyone who helps me get this situated has a beer or two on me, as long as you are in the greater metro Detroit area, or don't mind traveling a bit!

• Target to browse in order to insert a file

  - by Abid

  I have created an application using PHP and HTML. I insert it in my Linux server. I open it from my windows machine using the browser. I should in this application insert a file. When i click "insert file", instead of i have a window that browse the Linux server , i get a window that browse my local machine. And when i click insert , nothing is copied to the server. The code to insert file is: Filename: <input type="file" name="file" id="file"> So what should i do to force this application to browse the Linux machine when i open it from my local machine?

• mounts aren't case-sensitive

  - by Asi

  I mounted a few drives from Linux boxes in my network, but those mounts aren't case-sensitive. The mount command I used ( from the man mount.cifs, case-sensitive should be the default ): mount //10.0.1.10/remote_folder /local_folder -t cifs -o username=xxxx,password=xxxx but those mounts aren't sensitive. for example doing: ls -l /local_folder/testfile.txt ls -l /local_folder/TESTFILE.TXT give's the same result... instead of 'file not found' Couple of important points: All drives are running on Linux machines. My local machine is running Fedora 18 and it is case-sensitive for ANY folder/file expect the mounted drives. All drive/mounts are case-sensitive when when doing SSH. So if I SSH from my local machine to a remote machine, doing ls -l /local_folder/TESTFILE.TXT will say file not found as it should. So I believe the issue is in my local machine and not in the way I did the mount. but I'm not sure where to look next (I'm new to Linux)

• Unable to access network resources through VPN

  - by fbueckert

  I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.

• Why can't anyone else access my website in IIS on Windows 7?

  - by Rod

  I've got an ASP.NET application that I have in IIS on my Windows 7 Ultimate machine. I've tested it from that machine and it works fine. This machine is in my home network, a simple peer-to-peer network. The strange thing is that no one else in my network can access that website. Why is that? There are other Windows 7 machines here, and they're all in the some homegroup. When I attempt to access the website on my machine from one of the other machines, it fails and that's it. So, what's wrong?

• VMWare Converter recommendations

  - by Tank Szuba

  I have two Ghost 14 backups of my machine. One for the machine fully configured with apps after and XP install and one of the last update before i re-imaged it (it's XP, I re-image about once every six months). I recently wanted to try simply using my initial image in a virtual environment to do my testing that generally causes me to need to re-image. I used the VMWare converter to convert the Ghost images to a virtual machine to use in Virtual box but they fail to properly boot. They get stuck after the bios loads and windows begins loading. If I power down the machine and refire it it will go to the error screen in windows that asks if you would like to boot to a different mode. none selected make any difference. What are some possible errors I should look for in the conversion process or in my settings for the converter?

• How do UEFI and virtual machines relate to each other?

  - by Iterator

  I am trying to get my head around UEFI (Unified Extensible Firmware Interface) and it's not entirely clear to me how this affects virtual machines. Thus, there are three parts to this question: Is UEFI an advance in hardware support for virtualization? All other things being equal, would a machine with UEFI be more likely to run a virtual machine more efficiently than one without, or does UEFI cause any performance hits that negate any speed improvements from a virtual machine? Would the difference in execution be visible to code running in a virtual machine? (In theory, it shouldn't, but in practice?)

• Logon Failure: the target account name is incorrect after making a ghost image of a server

  - by cop1152

  I recently replaced a failing SCSI drive in a Windows 2000 server with an IDE drive. I made an image of the SCSI drive and Ghosted it. The purpose of the machine was to give out DHCP at one location and host a couple of files. When I restarted the machine with the new drive, DHCP appears to be working fine, but I cannot get to any of the shares. Instead, I get the following message when attempting to navigate using Explorer. Logon Failure: the target account name is incorrect It appears that this machine is not communicating with the main domain controller. Changes to user accounts (performed on the domain controller) are not replicated on this machine.

• Setting up squid proxy server to in turn connect using another proxy server [closed]

  - by AnkurVj

  My institute uses the Squid proxy server and authentication mechanism requires username and password to be entered. This means that, I can log in on only one machine at a time and Internet access for me is restricted to that machine. I sometimes require Internet access on multiple machines simultaneously. What previosuly worked for me was the following : On one of my own machines A, I set up a Squid proxy server that allowed all local machines without any username and password. I configured rest of the machines to use this machine A as the proxy server. On machine A I logged into the institute proxy server using my browser. This way, I could access Internet from all my machines, by effectively channeling my requests through the server A. Recently, I lost that machine and configuration and now I tried to set it up again in the same manner. However, I cant seem to remember exactly how I made it work. I keep getting Connection Refused (111) on other machines. My guess is that my squid server isnt able to forward requests from other machines to the actual squid server. I could use any help for debugging this problem. I don't want to use alternatives such as ssh tunneling. This solution has worked for me in the past, I just don't remember how to set it up the same way again.

• Selecting Interface for SSH Port Forwarding

  - by Eric Pruitt

  I have a server that we'll call hub-server.tld with three IP addresses 100.200.130.121, 100.200.130.122, and 100.200.130.123. I have three different machines that are behind a firewall, but I want to use SSH to port forward one machine to each IP address. For example: machine-one should listen for SSH on port 22 on 100.200.130.121, while machine-two should do the same on 100.200.130.122, and so on for different services on ports that may be the same across all of the machines. The SSH man page has -R [bind_address:]port:host:hostport listed I have gateway ports enabled, but when using -R with a specific IP address, server still listens on the port across all interfaces: machine-one: # ssh -NR 100.200.130.121:22:localhost:22 [email protected] hub-server.tld (Listens for SSH on port 2222): # netstat -tan | grep LISTEN tcp 0 0 100.200.130.121:2222 0.0.0.0:* LISTEN tcp 0 0 :::22 :::* LISTEN tcp 0 0 :::80 :::* LISTEN Is there a way to make SSH forward only connections on a specific IP address to machine-one so I can listen to port 22 on the other IP addresses at the same time, or will I have to do something with iptables? Here are all the lines in my ssh config that are not comments / defaults: Port 2222 Protocol 2 SyslogFacility AUTHPRIV PasswordAuthentication yes ChallengeResponseAuthentication no GSSAPIAuthentication no GSSAPICleanupCredentials no UsePAM yes AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT AcceptEnv LC_IDENTIFICATION LC_ALL AllowTcpForwarding yes GatewayPorts yes X11Forwarding yes ClientAliveInterval 30 ClientAliveCountMax 1000000 UseDNS no Subsystem sftp /usr/libexec/openssh/sftp-server

• Configure Postfix to use external MX servers for delivery of local mail if user is unknown

  - by mr.b

  I have a following setup: linux box with postfix configured to be responsible for example.com domain domain's MX servers are configured so that mail sent to example.com is sent to google mail servers several user accounts on linux machine exist (same machine also hosts example.com site) When someone from the outside attempts to send mail to address ending with @example.com, it gets routed to google mail (and there handled appropriately). When linux machine tries to send mail to outside world, mail is delivered correctly, as reverse dns and spf records are configured correctly, so linux machine is valid mail sender for example.com domain (along with google mail servers). However, here's the problem. When php application (hosted at linux box) tries to send mail to [email protected] (and someuser doesn't exist on linux box), it fails, since it doesn't even consult google mail servers, but postfix smtp locally concludes that "someuser" is unknown. So, the question is: how do I tell postfix to relay mails sent to @example.com domain to google mail servers (so, to servers specified in MX records), IF and only if a mailbox is not found locally.

• Ubuntu server hangs on reboot "could not stat resume device file"

  - by matnagel

  Instead of booting into the running system this machine stops and on the terminal I can see a message: could not stat resume device file /dev/sdb5 When I attach a keyboard and press enter the boot continues and the machine comes up like normal. But it's essential that this machine comes up under most circumstancs alone. There never was something like a "resume" on this machine. I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here. There is a software raid running on the box. This is the syslog during boot: http://privatepaste.com/ff0fd0a51c/sdabfjahfgasjkgfu4gfsdzjcgfafasdjfhgasdcjfgauzfgafasgdufzg How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.

• A few tips on deploying Secure Enterprise Search with PeopleSoft

  - by Matthew Haavisto

  Oracle's Secure Enterprise Search is part of PeopleSoft now.  It is provided as part of the Peopltools platform as an appliance, and is used with applications starting with release 9.2.  Secure Enterprise Search is a rich and powerful search product that can enhance search and navigation in PeopleSoft applications.  It also provides useful features like facets and filtering that are common in consumer search engines.Several questions have arisen about the deployment of SES and how to administer it and insure optimum performance.  People have also asked about what versions are supported on various platforms.  To address the most common of these questions, we are posting this list of tips.Platform SupportSES 11.1.2.2 does not support some of the platforms supported by PeopleTools, such as Windows 2012 and AIX 7.1. However, PeopleSoft and SES can use different operating system platforms when SES is deployed on a separate machine.SES 11.2.2.2 will have the required platform support for PT 8.53 in the future. We are planning to certify PT 8.53 once the testing is complete in 8.54 development and all platform support is released for 11.2.2.2.ArchitectureWe recommend running SES on a separate machine (from your apps) for two reasons:1.    SES bundles specific WebLogic, Java, and Oracle DB versions and might need different OS patches at a minimum than PeopleSoft. By having SES run on a different machine, these pre-requisites can be managed better through their lifecycle independenly for PeopleSoft and SES.2.    SES is resource intensive - it runs it's own WebLogic and Oracle database. By having SES run on its own machine, sufficient resources can be allocated to SES and free the PeopleSoft servers from impacts of SES load patterns.We will be providing a comprehensive red paper covering PeopleSoft/SES administration in the near future, but until that is published, we'll post tips on this blog.

• Ubuntu 13.04 under Parallels Desktop - Black Desktop after X Windows Update

  - by Bob Reckhow

  I have been running Ubuntu 13.04 successfully on a MacBook Pro in a virtual machine in Parallels Desktop 9. Today (2013-10-17) after applying today's Ubuntu update, which included updates to X Windows, my Ubuntu 13.04 virtual machine launches, the launcher comes up, but the screen background is solid black, rather than the shaded orange colour of the default desktop background (and my desktop icons are "hidden behind this blackness", as well). I can launch applications from the launcher, and there is a very brief white flash on the screen, and then it returns to black. It's as if there is a "black blanket" covering the entire screen, so there is no way to interact with any application windows using the keyboard or mouse. The icons of the launcher are responsive to the mouse, so I can right-click and quit any application I have launched. But the rest of the screen is non-responsive to keyboard or mouse. This same behaviour happens with two different versions of Parallels Tools, so I am quite sure this is not a Parallels problem per se, although I could believe that it could be a paroblem with the interface between Parallels and this new updated X Windows code. Could anyone tell me what has happened, and how I might be able to fix this problem, so I can continue to use my Ubuntu 13.04 virtual machine? (I do have the option of reverting to a previous version of my virtual machine from before this update, but if possible I would prefer to keep my version of Ubuntu 13.04 up to date with the latest updates.) Thanks, Bob

• Create an AWS AMI for Ubuntu with GUI which automatically launches web browser

  - by Rory MacDonald

  I've got an ubuntu AMI setup with ubuntu desktop installed and Chrome installed and set to boot on load (via the startup programmes menu within the ubuntu desktop) I've created an image of this AMI, but any time I launch a new instance running this, the Ubuntu GUI doesn't seem to load, until I SSH into the machine, enable VNC and then connect via Chicken VNC to the machine. At that point, the desktop appears to load + starts the browser. I really need the machine to boot and the browser to load without having to VNC into the machine.. Any help would be appreciated.
