  • How to increase video memory in libvirt/KVM gui?

    - by Dejan
    In the 'Virtual Hardware details', it lists the model as 'cirrus' with 9MB of RAM. The RAM field cannot be changed, but how to increate the video RAM? My host OS is RH6 and gust OS is Fedora16. EDIT: From guest OS, when I run xvinfo it displays 'no adaptors present'. I was trying to play a video using gstreamers xvimagesink plugin (XFree86 video output plugin using Xv extension). The problem is that xvimagesink is using hardware acceleration for video performance and hence the error Could not initialize Xv output. I guess I'll have to configure hardware acceleration for the guest.

  • Samba between Ubuntu server 10.10 and Windows Vista, Windows 7

    - by chepukha
    Hi all, I have a linux box running Linux server ubuntu 10.10. I have installed Samba on this linux box and want to share files with my laptops which run Windows Vista home and Windows 7 home. I have been struggling with the setup for almost a month but couldn't get it right. If I try to access share folder from Windows Vista, I get message "Windows cannot access \\server_ip_address". Error code: 0x80070035. The network path was not found. If I access from Windows 7, then after entering password to login I can see the list of share folders on Linux box. But if I click on a share folder, I get the same error message as above. Tail /var/log/samba/log.windows7-pc I got the following message: [2011/03/16 00:17:41.427238, 0] smbd/service.c:988(make_connection_snum) canonicalize_connect_path failed for service sharemedia, path /root/sharemedia Here is my setting in smb.conf [global] share modes = yes netbios name = Samba workgroup = WORKGROUP wins support = yes encrypt passwords = true [sharemedia] comment = Tesing sharing using Samba path=/root/sharemedia/ public = yes valid users = samba_usr_name ; make sure all files are sensible permissions create mask = 0660 force create mask = 0660 directory mask = 2770 force directory mask = 2770 directory security mask = 0000 ; Normal share parameters read only = no browseable = yes writable = yes guest ok = no

  • How do you monitor SSD wear in Windows when the drives are presented as 'generic' devices?

    - by MikeyB
    Under Linux, we can monitor SSD wear fairly easily with smartmontools whether the drive is presented as a normal block device or a generic device (which happens when the drive has been hardware RAIDed by certain controllers such as the one on the IBM HS22). How can we do the equivalent under Windows? Does anyone actually use smartmontools? Or are there other packages out there? The problem is that SCSI Generic devices just don't show up in Windows. If the drives aren't RAIDed we can see them fine. How I'd do it in Linux: sles11-live:~ # lsscsi -g [1:0:0:0] disk SMART USB-IBM 8989 /dev/sda /dev/sg0 [2:0:0:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg1 [2:0:1:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg2 [2:1:8:0] disk LSILOGIC Logical Volume 3000 /dev/sdb /dev/sg3 sles11-live:~ # smartctl -l ssd /dev/sg1 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 26~ Percentage Used Endurance Indicator |_ ~ normalized value sles11-live:~ # smartctl -l ssd /dev/sg2 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 3~ Percentage Used Endurance Indicator |_ ~ normalized value

  • Getting FC11 to run under VMware Server, converted from physical machine

    - by Kristian
    I have a FC11 installation that I have converted to a VMware disk image to run om my VMware Server. I converted it with qemu-img, as the VMware Converter software apparently only converts Linux hosts to VMware Infrastructure servers. The disk image boots fine (grub is loaded and boots the kernel) but it seems like the disk is not found by the kernel, and the boot process stalls. Hotplugging USB devices work (the kernel prints debug information) and I'm able to press keys (Ctrl-Alt-Delete for instance). The VMware guest OS is set to RedHat Enterprise Linux 5 (32 bit), and I have tried both the LSI Logic, LSI Logic SAS and VMware Accelerated SCSI SCSI controllers, to no avail. I'm able to boot an installer disk and get into rescue mode and mount the filesystem, so my question is, what do I need to do to the guest kernel / initrd image to make it recognize the virtual disk?

  • Cannot connect to Musicbrainz VirtualBox through SSH using Mac

    - by olovholm
    I am trying to connect my mac terminal shell to a VirtualBox running the Musicbrainz server.

  • Using IIS7 as a reverse proxy

    - by Jon
    My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy. http://serverfault.com/questions/55309/using-iis7-as-a-reverse-proxy I need to have IIS the main site and linux (Apache) being the proxied site(s). so I have site1.com (IIS7) site2.com (Linux Apache) they have subdomains of sub1.site1.com sub2.site1.com sub3.site2.com I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how). I can not have it running as Apache doing the proxying as I need IIS exposed directly. any and all advice would be great. EDIT I think this might help me: <rule name="Canonical Host Name" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTP_HOST}" negate="true" pattern="^cto\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="^antoniochagoury\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="www.antoniochagoury\.com$" /> </conditions> <action type="Redirect" url="http://www.cto20.com/{R:1}" redirectType="Permanent" /> </rule> from: http://www.cto20.com/post/Tips-Tricks-3-URL-Rewriting-Rules-Everyone-Should-Use.aspx I will have a look at this when I have access to the IIS7 box. Thanks

  • How to create RPM for 32-bit arch from a 64-bit arch server?

    - by Gnanam
    Our production server is running CentOS5 64-bit arch.

  • Active directory Kerberos OSX problems

    - by Temotodochi
    I'll try to keep this short, but informative. I'm currently unable to bind OSX lion (10.7.4) machines to our AD. OSX kerberos (heimdal) is unable to locate the KDC service. However i can bind linux & windows machines to the AD without any problems in the same network AD controls the domain DNS and all the relevant _kerberos._tcp.x.domain.com and _kpasswd SRV DNS records are there and resolve fine when tried from OSX machines. Defined ports are open for service and manually accessible from OSX. When i try kinit in the OSX, i can get the first auth through (wrong passwords fail instantly), but when supplied with correct password, kinit fails after some waiting with "unable to reach KDC". All machines run NTP and have correct time. During testing, network is not firewalled between the machines Linux and windows machines have no problems whatsoever I have tried with and without /etc/krb5.conf - OSX by default does not need it in the krb5.conf i used a working config from one of our linux machines. dsconfigad fails with simple "connection failed to the directory server" I'm a bit baffled with this. OSX is like the KDC is nowhere to be found and at the same time my test machines with windows 7 and some linux (centos 6 & debian 6) machines have no problems whatsoever. Same network, same configurations. I'm missing some vital piece of configuration somewhere, and i can't find out what it is.

  • How to get gigabit network speeds on Windows XP?

    - by JB
    We've just installed gigabit switches at work, and things on the Linux side are going well. Our linux boxes, which use a Intel Corporation 82566DM-2 Gigabit nic (according to lspci), consistently get over 900 mbits/sec: iperf -c ipserver ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.40.9 port 39823 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.08 GBytes 929 Mbits/sec We have a bunch of Windows XP 64-bit machines that use Broadcom NetXtreme 57xx cards. I spent around a day trying to get equivalent speeds on them, but couldn't get above 200 Mbits/sec. I noticed the Windows iperf tests said that the TCP window size was 8 Kb by default (as opposed to 16 Kb on Linux, so I modified my test to reflect that. Still no love. I went to Broadcom's site, downloaded the latest drivers for the card and installed. Still no love. However, finally, I tried a 64 Kb window size with the new drivers, and finally an improvement! $ iperf -c ipserver -w64k ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [ 3] local 192.168.40.214 port 1848 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 933 MBytes 782 Mbits/sec Much better, but still not really taking advantage of the full capabilities of the network. If the Linux box can reach 950 Mbits/sec consistently, this box should be able to as well. Also, if you're wondering about the medium, this is over the same cable...I'm switching back and forth. Any suggestion or ideas would be really welcome. Thanks!

  • Best practice for system clock sync on KVM host

    - by Tauren
    I have an Ubuntu 9.10 server running as a KVM host with ntpd installed on it. The host system has the correct system time. At the moment I only have a single KVM guest, also Ubuntu 9.10 server. I do not have ntpd installed on it, and I just discovered the clock is about 6 minutes slow. It wasn't that way when it was installed about a month ago. I thought that I only needed to keep the host clock synchronized and that the guests used the host clock. But maybe that is a memory from using OpenVZ. I believe the reasoning was related to only the host could modify the physical system clock. Is running ntpd on both the host and all the guests the correct thing to do? Or is there something else that is preferred? How should I keep the guest clocks in sync?

  • Unable to see a newly added virtual disk in Virtualbox

    - by uswaretech
    I am using virtualbox with Host: Ubuntu 9.10 Guest Win 7 My old virtual disk was filing up so I added a new virtual disk. After I restarted the guest, I can not see it in the My computer. I can see a new disk in the device manager though. The new disk was added as primary slave. What do I need to do to see it? I am guess I need to format the new virtual disk, but since I dont see any drive letter mapped to it, I am not sure of how to do this.

  • Where to get grub files without using grub-install

    - by Jacky
    I am in a particular situation. I have a MacBook Pro with no internal CD drive and both MacOS X (minimal setup) and Linux (my main system) is installed. During a cross-upgrade to Ubuntu 12.04 I messed up grub, so that my /boot/grub directory is basically empty. This means I can't boot Linux on the laptop anymore but only get into grub rescue. Normally this is no issue as you'd just boot from a rescue CD or USB stick, but unfortunately with a MacBook Pro this is not possible (I have reFIT installed and it attempts to boot, but it fails and the manual says that Apple's EFI firmware is not able to handle this situation). From MacOS X, however, I still have write access to the Linux partition. I've now been trying to figure out how to populate the /boot/grub folder with the necessary files, to no avail so far. The ISO image of Ubuntu 12.04 contains an EFI folder which is not what I am looking for, instead I need the normal.mod files for the grub version of Ubuntu 12.04. I do not have any other machine to set up a virtual machine of Ubuntu 12.04 to extract this from after a grub-install, so I am asking for ideas here how to solve this mess. P.S.: I installed the Linux previously when I still had a working internal CD drive. This is gone now.

  • Understanding an Application based on the OS interaction with a Hypervisor

    - by Dewy
    Following I will ask a few specific questions but I will set the stage first. My goal is to monitor Applications in a very odd place - between the OS and a Hypervisor. If you have comments about this probably unachievable goal please do educate me. One good advice or link can save me days of work. Now to my current attempt. I installed on WinXP a VirtualBox (being open-source) and got a guest OS of latest Ubuntu running within. Where should I go next? Can I set the logs to show all memory/CPU/disk instructions of the guest OS? Thanks, Dewy

  • NX Client for Windows 7 Opens Remote Desktop in Multiple Windows

    - by Corey Kennedy
    What I'm trying to do: access my Ubuntu desktop remotely via NX Client on my Windows 7 laptop. My environment: server: Ubuntu 10.10 on AMD 1Ghz/512MB RAM PC client: Windows 7 on ThinkPad sl510 Software: server is running NXServer 3.4.0. Using xfce4 window manager. Laptop is using NXClient for Windows In my NX Client "Desktop" settings I've selected "Unix" and "Custom" for OS and environment. I've also specified "startxfce4" as the application to launch when NX connects. I am able to authenticate an NX session on my laptop. By this I mean, I can start the client on my laptop, enter credentials for my Linux user, and NX establishes a connection to the server and attempts to open a remote desktop window. The problem, though, is that this remote desktop is "fragmented" into many Windows. One window will display the bulk of my desktop (complete with desktop icons for "Home," "File System," and "Trash") while another window will contain the taskbar, and another window will contain the application strip. I can select each of these Windows individually, but I cannot click on any objects within them. I've searched Super User, Ubuntu Forums, NX help, Server Fault, and tried many Google searches - none have turned up another case of this particular problem. I'm stumped. Does anyone have any suggestions for what I might try? I'm guessing the problem has to do with my xfce config files, but I've only just setup this server - it's been a long time since I've used Linux and there's a lot I just don't know. What I am NOT trying to do: use Desktop sharing from Ubuntu, whereby I VNC into a desktop that I've already established on the server. I am trying to configure this Linux box as a headless server that I can stash someplace out-of-the-way in my house, then interact with through my laptop. I don't want to have a monitor or keyboard connected to the Linux box. Thanks for your help!

  • Windows server 2008R2 routing with single NIC

    - by Fabian
    I'm trying to duplicate a Linux server configuration to a windows server 2008R2 box. Basicaly this linux server acts as a router, but it is doing its job with only 1 interface (1 NIC). Here is the network configuration in place (I cannot change it) : INTERNET <== Router (local ip = 194.168.0.3) <== linux Server (ip : 194.168.0.2). The router is configured with a DMZ to 194.168.0.2, and only allow this IP to connect to internet (Cannot change this router configuration). The linux server is configured with a default gateway to 194.168.0.3, with the option : "Act as router". All other computer on the lan have this configuration (given by DHCP) : IP range : 194.168.0.X MASK : 255.255.255.0 Default gateway : 194.168.0.2 And everything is working perfectly. I'm trying to reproduce this way of routing with only one NIC from a windows server 2008R2, but it seems that you cannnot do it with only one NIC (all exemples I see are refering to 2 NIC with 2 different network). Does someone have an idea how to achieved this in Windows server 2008R2 ? Tx you for your help ! Fabian.

  • Sendmail : Mail delivery of same domain to internal or external mail server.

    - by Silkograph
    Its bit difficult to explain but very simple problem. We have internal sendmail server and hosted server. Both are set to same domain name. We have mixed mail accounts. For example we have two user in one office. [email protected] is local only [email protected] is internal plus external. Internal means we create user on local linux box where sendmail is set. External means we create user on local and hosted server. [email protected] can send mails to any internal user created on Linux box where sendmail is installed. But he can not send mail to outside domain and no mail can be sent to him as there is no account created on external hosted server. [email protected] can send mails to internal as well as all other domains through sendmail's smart_host feature, which uses hosted server's smtp. [email protected] can get all external emails internally through Fetchmail on linux box. Now we have third user [email protected] who will be always outstation and can use external server only. So I can not create account on local linux box for [email protected] because his mail will get delivered locally only. I don't want to create alias and send his mails to gmail or yahoo's account. I want to send emails to his external account from any internal user. How this can be done? Thanks in advance.

Full-cone iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source iptables -t nat -A PREROUTING -i eth0 -j DNAT --to-destination Restricted cone iptables -t nat POSTROUTING -o eth1 -p tcp -j SNAT --to-source iptables -t nat POSTROUTING -o eth1 -p udp -j SNAT --to-source iptables -t nat PREROUTING -i eth1 -p tcp -j DNAT --to-destination iptables -t nat PREROUTING -i eth1 -p udp -j DNAT --to-destination iptables -A INPUT -i eth1 -p tcp -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -i eth1 -p udp -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -i eth1 -p tcp -m state --state NEW -j DROP iptables -A INPUT -i eth1 -p udp -m state --state NEW -j DROP Port-restricted cone iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source Symmentric echo "1" /proc/sys/net/ipv4/ip_forward iptables --flush iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE --random iptables -A FORWARD -i eth1 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT What I did : OpenSuse guest with Two Virtual adapters - eth0 and eth1 -- eth1 with address 10.0.3.15 /eth1:1 as 10.0.3.16 -- eth0 with address 10.0.2.15 now running stund(http://sourceforge.net/projects/stun/) client/server : Server eKimchi@linux-6j9k:~/sw/stun/stund ./server -v -h 10.0.3.15 -a 10.0.3.16 Client eKimchi@linux-6j9k:~/sw/stun/stund ./client -v 10.0.3.15 -i 10.0.2.15 On all Four Cases It is giving same results : test I = 1 test II = 1 test III = 1 test I(2) = 1 is nat = 0 mapped IP same = 1 hairpin = 1 preserver port = 1 Primary: Open Return value is 0x000001 Q-1 :Please let me know If any has ever done, It should behave like NAT as per description but nowhere it working as a NAT. Q-2: How NAT Implemented in Home routers (Usually Port Restricted), but those also pre-configured iptables rules and tuned Linux

  • How to share internet connection on Mac os x to Virtualbox vm’s using Host-only

    - by redben
    In one line : is the following possible : Airport <- "osx bridge" - vbox-Host-only - vm's Virtualbox (3.1.4) setup : Host : Mac OS X 10.5 Guest : Ubuntu Linux adapter1 - Bridged (en1: Airport) : To give the vm access to internet and communicate when Airport is connected adapter2 - Host-Only (vboxnet0) : To enable host/guest communication when Airport is not connected I'd like to make it simpler and only keep adapter 2 (host-only) and relying on os x connection sharing/bridging I thought i could just keep the Host only configuration, and on the host go to internet sharing and select "share from airport" to vboxnet0 . Only to find out that vbox's virtual interface doesn't appear in the interfaces list on os x preferences. I know that on a linux host you could install something called bridge-utils and use that to bridge the two insterfaces. Is there any thing like that for Mac ?

  • VMware - Not printing in order

    - by nate
    I am using vmware workstation 7. Guest is Windows XP. The host OS is Windows 7. When I queue the printer with multiple documents, the printer doesn't print in order. It seems to print the smaller size in data of documents first. The printer is an HP printer. This is what I have tried so far: I have tested this on the host machine, and it works fine. I have tested this on other host machines(XP Windows7), and it works fine. I have tested other HP printers I have tested it another another guest OS Windows 7 I have tested different drivers Thanks in advance for any help on this one!

  • Windows server 2008R2 routing with single NIC

    - by Fabian
    I'm trying to duplicate a Linux server configuration to a windows server 2008R2 box. Basicaly this linux server acts as a router, but it is doing its job with only 1 interface (1 NIC). Here is the network configuration in place (I cannot change it) : INTERNET <== Router (local ip = 194.168.0.3) <== linux Server (ip : 194.168.0.2). The router is configured with a DMZ to 194.168.0.2, and only allow this IP to connect to internet (Cannot change this router configuration). The linux server is configured with a default gateway to 194.168.0.3, with the option : "Act as router". All other computer on the lan have this configuration (given by DHCP) : IP range : 194.168.0.X MASK : 255.255.255.0 Default gateway : 194.168.0.2 And everything is working perfectly. I'm trying to reproduce this way of routing with only one NIC from a windows server 2008R2, but it seems that you cannnot do it with only one NIC (all exemples I see are refering to 2 NIC with 2 different network). Does someone have an idea how to achieved this in Windows server 2008R2 ? Tx you for your help ! Fabian.
