  • Install virtualization software on a remote linux machine as a non-root user

    - by Cetin Sert
    Hi, 1) Is there a way for me to install VirtualBox as a non root user? I compiled it from the sources but cannot find a way to load the kernel modules it requires? Is there anyway to make it run? 2) Is there any other virtualization software you have ever installed on linux successfully as a non root user, VMWare, Parallels, etc.? The aim is to run Windows as a virtual machine with more than 16GB RAM. Bests, Cetin

  • DNS CNAME - SSL-certificate issue.

    - by Phoibe
    Hey, I have obtained an SSL certificate by Thawte for domain.com Now my infrastructure changed due to heavy load I have mx.domain.com as SMTP relay storage.domain.com as Mail-Storage and domain.com pointing at Web-Server Every server is hosted on another dedicated/virtual server with individual IP. I do not want to put the Web-Server on the Mail-Storage for security reasons but I do want to use my SSL-Certificate for the Mail-Storage(POP3S/IMAPS). Is that possible or how do I solve that issue?

  • How can I troubleshoot Virtualbox port forwarding from Windows guest to OSX host not working?

    - by joe larson
    There are a plethora of questions about virtual box port forwarding problems but none with my specific details. I have a Windows install living in Virtual Box, hosted within OSX. I've got several webservers running on localhost on different ports within the Windows install. I cannot for the life of me get port forwarding to work so I can access those webservers from OSX. My settings look like this (yes I have a NAT adapter): And in my vbox configuration file the relavent portion looks like this: <NAT> <DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/> <Alias logging="false" proxy-only="false" use-same-ports="false"/> <Forwarding name="RLPWeb" proto="1" hostport="7084" guestip="127.0.0.1" guestport="7084"/> <Forwarding name="UtilWeb" proto="1" hostport="4040" guestip="127.0.0.1" guestport="4040"/> <Forwarding name="WCARLP" proto="1" hostport="8084" guestip="127.0.0.1" guestport="8084"/> <Forwarding name="WCAUtil" proto="1" hostport="4848" guestip="127.0.0.1" guestport="4848"/> </NAT> I've turned off the Windows firewall to ensure it is not interfering, and I am not running a firewall on OSX. Anyway, when I attempt to go to for example http://127.0.0.1:4040/ on any of my OSX browsers, it will eventually time out. The log file for this VM shows that it is correctly reading the settings and implying it's doing the right thing here: 00:00:08.286 NAT: set redirect TCP host port 4848 => guest port 4848 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 8084 => guest port 8084 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 4040 => guest port 4040 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 7084 => guest port 7084 @ 127.0.0.1 00:00:08.290 Changing the VM state from 'LOADING' to 'SUSPENDED'. 00:00:08.290 Changing the VM state from 'SUSPENDED' to 'RESUMING'. 00:00:08.290 Changing the VM state from 'RESUMING' to 'RUNNING'. 00:00:08.337 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000012017d000 w=1834 h=929 bpp=32 cbLine=0x1CA8, flags=0x1 00:00:09.139 AIOMgr: Host limits number of active IO requests to 16. Expect a performance impact. 00:00:13.454 NAT: DHCP offered IP address 10.0.2.15 I've tried setting the Host IP to 127.0.0.1, and I've tried setting Guest IP blank and also 10.0.2.15. None of these seem to help. What else can I look at to troubleshoot this issue? Details of setup: OSX 10.6.8 Windows 7 Professional 64bit VirtualBox 4.1.2

  • Antivirus for Windows Server 2008 R2

    - by raja
    I am trying to get a Antivirus server for my Virtual Private Server that has Windows Server 2008 R2 x64 1.5 GB RAM and 40 GB HD. I see people have suggested for NOD32 or Kaspersky but they are not offering Internet security for one server in business edition (it starts with at least 5 PC) and they says I can't install home edition on my VPS as this is for business purpose. Is there any good antivirus/internet security program that I can buy for my single VPS? Any suggestion will help me. Thanks

  • Apache consuming large memory with Apache Mobile Filter

    - by VarunGupta
    I installed and configured Apache Mobile Filter module for Apache to redirect users to mobile version of our website, depending on their user agents. I configured the module to use WURFL. But as soon as I start Apache it hogs a large amount of memory (without any in-coming web requests): Resident Memory: 300 to 400 MB Virtual Memory: 300 to 650 MB Without this module, Apache was consuming much lesser memory (4 to 10 MB). What could be the reason here?

  • Xubuntu 9.10 LiveCD on USB fails with error can't open /dev/sr0: no medium found

    - by EricJLN
    Using Ubuntu's USB Startup Disk Creator (usb-creator-gtk), I created a LiveUSB from the Xubuntu 9.10 LiveCD. When booting, it stalls up with the Xubuntu mouse splash screen displayed. In attempting to troubleshoot, I used Ctrl-Alt-F1 to check out the first virtual terminal. On that screen, I see over and over again the lines: stdin: I/O error stdin: error 0 /init: line 1: can't open /dev/sr0: No medium found

  • DMZ and LAN on the same Windows Storage Server 2008 R2

    - by Sergei
    We are moving from EMC Celerra NS20 to Windows Storage Server 2008 R2. I would like to use deduplication feature in WSS (Single Instance Storage) for hosting data for our external FTP server.The idea is to use NFS server on WSS as datastore for Linux FTP server located in DMZ and CIFS services for servers in LAN. Using Celerra fileserver I was able to create multiple instances of fileservers with multiple virtual interfaces and separate filesystems so all data and networks would be separated. Would it be possible to do something similiar on WSS?

  • Is there Powershell way to re-apply a restored password for the IIS IUSR account?

    - by Philippe Monnet
    On one of our IIS web servers the IUSR account suddenly expired or got corrupted, I recovered the password from the IIS metabase (using Cscript adsutil.vbs get w3svc\anonymoususerpass after switching IsSecureProperty = False). I then reset the password accordingly. Now I have to re-key that password on the Directory Security tab of all virtual directories (for the anonymous account) of all web sites on that server. Is there a way to automate this using Powershell? (I have searched so far in vain)

  • getUserPrincipal() in JCIFS / Lan-Manager authentitation level setting in Windows 2k8

    - by Chris
    I have to find out in which exact format JCIFS stores the user principal in the "getUserPrincipal()" property. Therefor i created a test Environment like this: Windows Server 2008 Domain Controller Domain named "MYDOMAIN" Many Testusers in Active Directory Tomcat Application Server with my Web Application (which simply reads the user Principal and displays its values). The user should be logged in to the web-application with SSO therefor i need the format that jcifs is using to store the user. (For example user@MYDOMAIN or MYDOMAIN\user...) I tested the Authentication with other SSO frameworks with Kerberos Method and it works as expected. I'm now trying to use SSO through the NTLMHttpFilter of JCIFS. When i try to login i get the following error message: jcifs.smb.SmbException: The parameter is incorrect. jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:541) jcifs.smb.SmbTransport.send(SmbTransport.java:641) jcifs.smb.SmbSession.sessionSetup(SmbSession.java:322) jcifs.smb.SmbSession.send(SmbSession.java:224) jcifs.smb.SmbTree.treeConnect(SmbTree.java:176) jcifs.smb.SmbSession.logon(SmbSession.java:153) jcifs.smb.SmbSession.logon(SmbSession.java:146) jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:189) jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:121) Regarding to the documentation i'm using to configure this, this is a know issue with the Group policy. It is stated there, that i have to change the Group policy "Networkaccess: lan-manager authentication level" to respond to NTLMv1 request. I have done this, but it's still not working. So what i also have to configure is the same policy on the client computer. I have to change the policy, so that the client computer sends NTLMv1. But it is always sending NTLMv2 tokens. The problem now is that i'm somehow not able to change this setting. (I already was before) because the dropdown box to choose the authentication method is "greyed out". edit: just to make this clear, this dialog is on the client-side in the "local-security policies" As you can see from this screenshot, the chosen method is "Only send NTLMv2 responses" which is the wrong setting and i'm pretty sure that this is causing the error above. My question is now, why can't i change this setting? Why is it greyd out?

  • Apache heavy load VIRT vs RES memory

    - by pako
    I have a Debian 5 server, which gets a lot of traffic. Right now the server has 4 GB of RAM and no swap memory. I see in top that Apache processes consume roughly 180 MB virtual memory (VIRT) each, and 16 MB of real RAM (RES). So how many Apache threads can I have running at the same time? About 4 GB / 180 MB = 22 or 4 GB / 16 MB = 256?

  • File Not Found error launching Guest OS in a non-administrator user account

    - by ToreTrygg
    Hi, I am running Fusion 2.0.6 (196839) on an iMac running 10.6.2 with 3 user accounts (1 Administrator). I have Fusion set up to share the Guest OS, and it's been working splendidly for nearly a year. Within the Guest OS (Windows XP PRO), there are also 3 user accounts (1 Administrator). Last night I went to back up my VM to an external drive, and to minimize the file size and transfer time, I deleted all Snapshots but the most-recent one. I then backed up the VM externally (28.23 GB). Today, one of my users tried to launch the Guest OS from within her user account, and received the following error message: "File Not Found: Windows XP Pro-000006.vmdk "This file is required to power on this virtual machine. If this file was moved, please provide its new location." My two choices are Cancel and Browse. When I browse, I can locate the Windows XP Pro-000006.vmdk file, which appears to be contained within the VM file (Windows XP Pro.vmwarevm). However, it still won't launch from a non-Admin user account. If I view the package contents of the VM file from the user account, the above file is present and appears to be created upon each launch of the Guest OS. If I go back to my Administrator account on the Mac and then launch Fusion, the Guest OS works perfectly for all 3 user accounts within XP Pro. I have tried to delete the Guest OS from Fusion's Library within the problem user account, then re-connect it to that Library, but the result is the same. The Guest OS data integrity is 100% -- but is accessible only from the OS X Administrator account. This problem only surfaced after deleting several older Snapshots. Again, the data is there, the Guest OS powers up normally in the Mac's Administrator account, but persistently returns the above error when attempting to power on from a non-Admin account on the Mac. I'm not sure how this is affecting the error, but when I look at Hard Disk Settings, the "unable-to-locate" file is the filename of the virtual HD. I don't want to make any changes to my (working) VM without any advice from the knowledgeable people on this forum. Any help will be greatly appreciated, thanks!

  • What is a 'best practice' backup plan for a website?

    - by HollerTrain
    I have a website which is very large and has a large user-base. I am trying to think of a 'best practice' way to create a back up or mirror website, so if something happens on domain.com, I can quickly point the site to backup.domain.com via 401 redirect. This would give me time to troubleshoot domain.com while everyone is viewing backup.domain.com and not knowing the difference. Is my method the ideal method, or have you enacted better methods to creating a backup site? I don't want to have the site go down and then get yelled at every minute while I'm trying to fix it. Ideally I would just 'flip the switch' and it would redirect the user to a backup. Any insight would be greatly appreciated.

  • Do I dare clicking Delete Volume instead of Delete Partition?

    - by Olle
    I have a VMWare machine with one VM. That VM has a virtual disk which in windows is configured with two partitions and then a lot of slack space, as illustrated here: http://piclair.com/q8g5s What I want to do is delete the partition of 639 GB. However, since it's a dynamic disk, the right menu item says "Delete Volume" instead of "Delete Partition" (when I right click the 639GB space). My question is weather I dare to use "Delete Volume". I have read doing stuff like this on a dynamic volume can cause other partitions/volumes to go corrupt.

  • How long should cobbler sync take to run?

    - by Robert V. Bolton
    I have setup a Fedora 13 minimum install inside of a VirtualBox VM, and am following this tutorial to setup Cobbler: PXE virtual network with Virtualbox and Cobbler When I go to run the initial cobbler sync the command seems hang. How long should it take to run this command? Since I did a minimum install of Fedora 13 am I missing a application that would prevent cobbler from executing the sync properly?
