  • What Hypervisors support non-homogenous clusters?

    - by edude05
    I've been using Citrx Xenserver for awhile on a few machines that don't support Hardware Virtualization as a test for various small servers. I recently have been experimenting with moving the PV Vms between machines but Xenserver gives me errors that roughly say I need to have homogenous hardware for this to work. Because of this I haven't been able to setup XenMotion or any of the nice features that come with server pooling in Xenserver. I'm considering moving away from XenServer, however I can't seem to find a Hypervisor that explicitly supports non-homogenous clusters. On a side note, we do have a few idenitally configured Dell 1950s that haven't had any VM solution setup on yet, so if we can find a solution that can allow us to move PVs to those as well that would be great. Non free solutions are OK as well. What hypervisor will allow this? Thanks!

  • Limit which processes a user can restart with supervisor?

    - by dvcolgan
    I have used supervisor to manage a Gunicorn process running a Django site, though this question could pertain to anything being managed by supervisor. Previously I was the only person managing and using our server, and supervisor just ran as root and I would use sudo to run supervisorctl restart myapp when needed. Now our server has to support multiple users working on different sites, and each project needs to be able to restart their own gunicorn processes without being able to restart other users' processes. I followed this blog post: http://drumcoder.co.uk/blog/2010/nov/24/running-supervisorctl-non-root/ and was able to allow non-root users to use supervisorctl, but now anyone can restart anyone else's processes. From the looks of it, supervisor doesn't have a way of doing per-user access control. Anyone have any ideas on how to allow users to restart only their own processes without root?

  • Rsyslog stops sending data to remote server after log rotation

    - by Vincent B.
    In my configuration, I have rsyslog who is in charge of following changes of /home/user/my_app/shared/log/unicorn.stderr.log using imfile. The content is sent to another remote logging server using TCP. When the log file rotates, rsyslog stops sending data to the remote server. I tried reloading rsyslog, sending a HUP signal and restarting it altogether, but nothing worked. The only ways I could find that actually worked were dirty: stop the service, delete the rsyslog stat files and start rsyslog again. All that in a postrotate hook in my logrotate file. kill -9 rsyslog and start it over. Is there a proper way for me to do this without touching rsyslog internals? Rsyslog file $ModLoad immark $ModLoad imudp $ModLoad imtcp $ModLoad imuxsock $ModLoad imklog $ModLoad imfile $template WithoutTimeFormat,"[environment] [%syslogtag%] -- %msg%" $WorkDirectory /var/spool/rsyslog $InputFileName /home/user/my_app/shared/log/unicorn.stderr.log $InputFileTag unicorn-stderr $InputFileStateFile stat-unicorn-stderr $InputFileSeverity info $InputFileFacility local8 $InputFilePollInterval 1 $InputFilePersistStateInterval 1 $InputRunFileMonitor # Forward to remote server if $syslogtag contains 'apache-' then @@my_server:5000;WithoutTimeFormat :syslogtag, contains, "apache-" ~ *.* @@my_server:5000;SyslFormat Logrotate file /home/user/shared/log/*.log { daily missingok dateext rotate 30 compress notifempty extension gz copytruncate create 640 user user sharedscripts post-rotate (stop rsyslog && rm /var/spool/rsyslog/stat-* && start rsyslog 2&1) || true endscript } FYI, the file is readable for the rsyslog user, my server is reachable and other log files which do not rotate on the same cycle continue to be tracked properly. I'm running Ubuntu 12.04.

  • More than 3 seconds "Initial Connection" time (webpagetest.org)

    - by George Tasioulis
    I'm having a weird issue with a vBulletin forum, on a 2? Xeon E5645 w/ 16GB RAM, cPanel and LiteSpeed webserver; It takes too long to start loading... When I tested it with webpagetest.org I saw that for every request there's a 3 second "Initial connection" delay, which I don't know why is happening. Here's a screenshot: CPU Load is between 0.03 and 0.05, I've got several GB of free RAM, practical no I/O activity, and this delay can occur even with only one visitor on the forum. Where do you suggest I start searching? What could be the reason for this kind of delay? I don't think it's the webserver, or the forum because there's another website on the server (total 2 sites) which is WordPress based, and has exactly the same issue with the 3 second initial connection delay. I believe it's OS related, but need a clue on where to start looking. Thanks in advance :)

  • Where to set catch-all address in Postfix (virtual mailboxes in affect)

    - by Cem
    I successfully configured Postfix to deliver messages to virtual mailboxes. I can set aliases and pipes inside /etc/postfix/virtual and mailboxes inside /etc/postfix/virtual_mailbox files. However, whenever I set a catch-all domain and point to a remote email address, it overrides all other virtual mailboxes and virtual aliases set in postfix. How can I set a catch-all forwarding to the remote email address when virtual mailbox is enabled? I set catch-all like this: @mydomain.com [email protected] Thanks for your help!

  • using python Paramiko for ssh: sudo: no tty present and no askpass program specified

    - by misteryes
    I want to use paramiko to ssh into a bunch a remote nodes and run some command line with root priviledge I have ssh key in my home directory and so i don't need to input password when I ssh into those remote nodes but when running the following script: def connect(hostname): ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(hostname, username='niky', pkey=paramiko.RSAKey.from_private_key(open('id_rsa'), 'passwd'), timeout = 240.0) return ssh def run(hostname): ssh = connect(hostname) (stdin, stdout, stderr) = ssh.exec_command("sudo ls") res = stderr.readlines() print hostname+': '+''.join(str(elem) for elem in res)+'\n' run(remote.nity.com) I got the following error: remote.nity.com: sudo: no tty present and no askpass program specified if I don't add sudo before ls everything works fine what are potential reasons ? thanks!

  • Ubuntu 10.04 Keyboard and Mouse Freezing Problem

    - by nitbuntu
    I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

  • What's an easy way to install a bunch of OSS apps in my home dir on my company's aging Redhat VNC servers?

    - by subopt
    My company's IT group doesn't want to install lots of common stuff on our VNC servers, which run RHEL 4. The list of stuff i want/need includes graphviz, midnight commander, various python libs, sqlite, netbeans, antlr, jdk1.6, etc. They've hobbled rpm somehow, so i can't do rpm --relocate. And i don't want the RHEL4 compatible revs of this stuff anyway. I've probably got the room to build all this stuff in my home dir, but i don't want to take forever tracking down dependencies. Looking for an easy way to get the apps/tools i need, and nothing (or very little) else. Any suggestions?

  • Why wireless adatper stop to work?

    - by AndreaNobili
    today I correctly installed the driver for the TP-LINK TL-WN725N USB wireless adapter on my RaspBerry Pi (I use RaspBian that is a Debian), then I setted up the wifi using the wpa-supplicant as explained in this tutorial: http://www.maketecheasier.com/setup-wifi-on-raspberry-pi/ This worked fine untill this evening. Then suddenly it stopped to work when I try to connect in SSH and the Raspberry is on the wireless (or rather it should be, as this is not in the list of my router's DHCP connected Client) The strange thing is that the USB wirless adapter blink so I think that this is not a driver problem. If I try to connect it by the ethernet I have no problem. It appear in my router's DHCP connected Client and I can connect to it by SSH. When I connect to it using ethernet if I perform an ifconfig command I obtain: pi@raspberrypi ~ $ ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:2a:9f:b0 inet addr:192.168.1.9 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:48 errors:0 dropped:0 overruns:0 frame:0 TX packets:59 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6006 (5.8 KiB) TX bytes:8268 (8.0 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:8 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1104 (1.0 KiB) TX bytes:1104 (1.0 KiB) wlan0 Link encap:Ethernet HWaddr e8:94:f6:19:80:4c UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So it seems that the wlan0 USB wireless adapter driver is correctly loaded. If I remove the USB wireless adapter and put it again into the USB port, the lasts lines of dmesg log is: [ 20.303172] smsc95xx 1-1.1:1.0 eth0: hardware isn't capable of remote wakeup [ 20.306340] RTL871X: set bssid:00:00:00:00:00:00 [ 20.306726] RTL871X: set ssid [g\xffffffc6isQ\xffffffffJ\xffffffec)\xffffffcd\xffffffba\xffffffba\xffffffab\xfffffff2\xfffffffb\xffffffe3F|\xffffffc2T\xfffffff8\x1b\xffffffe8\xffffffe7\xffffff8dvZ.c3\xffffff9f\xffffffc9\xffffff9a\xffffff9aD\xffffffa7\x1a\xffffffa0\x1a\xffffff8b] fw_state=0x00000008 [ 21.614585] RTL871X: indicate disassoc [ 21.908495] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 [ 25.006282] Adding 102396k swap on /var/swap.

Looking at the adapter status I obtain: pi@raspberrypi ~ $ ip link list dev wlan0 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT qlen 1000 link/ether e8:94:f6:19:80:4c brd ff:ff:ff:ff:ff:ff As you can see the mode is DORMANT but I think that this is normal because now I am connected using ethernet. I tryied to set up the adapter but it seems that I obtain no result, infact: pi@raspberrypi ~ $ sudo ip link set dev wlan0 up pi@raspberrypi ~ $ ip link list dev wlan0 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT qlen 1000 link/ether e8:94:f6:19:80:4c brd ff:ff:ff:ff:ff:ff pi@raspberrypi ~ $ sudo ip link set dev wlan0 up This is my /etc/network/interfaces file content and it is ok: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp and it is the /etc/wpa_supplicant/wpa_supplicant.conf that I think is ok (I did not change it compared to when it worked): ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="MY-NETWORK" psk="mypassword" key_mgmt=WPA-PSK } and infact if I execute a network scan I correctly find MY-NETWORK in the network list,infact: pi@raspberrypi ~ $ sudo iwlist wlan0 scan | grep ESSID ESSID:"TeleTu_74888B0060AD" ESSID:"MY-NETWORK" ESSID:"FASTWEB-1-PT6NtjL4TOSe" ESSID:"DC" So I reboot the system and I remove the ethernet cable but when I try to connect again to my raspberry I obatin the following error message: andrea@andrea-virtual-machine:~$ sudo ssh [email protected] ssh: connect to host 192.168.1.9 port 22: No route to host It seems that it can't connect using wireless. What could be the problem? What am I missing? How can I solve this situation? Tnx

  • Bad I/O scheduler?

    - by user62367
    os: up-to-date Fedora 14. Working as a "normal desktop". It's doing very well, but if i start VirtualBox, and e.g.: install a guest on it, it just "freezez". I mean if there are disk activities on a VirtualBox guest, then the computer becomes unrespondable..even the mouse is laggin for about 50 minutes.. What could be the bottleneck? What could be the problem? If anyone has any tips/howtos to speed it up, please help! It has a normal 2,5" HDD, with 5400 RPM. Does it worth for me if i buy a 2,5" HDD with 7200 RPM? T7200 cpu, 4 GByte RAM, "vm.swappiness = 0". Thank you!

  • What does "link to unknown" mean?

    - by Question Overflow
    I just upgraded my server to Fedora 17 which made a switch of my bootloader from GRUB Legacy to GRUB2. There are two symbolic links in the /etc folder that points to the files grub.conf and grub.cfg in /boot/grub and /boot/grub2 respectively. Though the targets seem correct, the link icons are displaying an X status which seems to indicate that the links are broken. Upon right-clicking the property type, it states "link to unknown". The file size of the link corresponds exactly with the file size of the target file, so, why does the links appear to be broken? The image of the link icons: As requested, the following are the outputs from the commands: $ ls -l /etc/grub.conf lrwxrwxrwx. 1 root root 22 Jul 14 2011 /etc/grub.conf -> ../boot/grub/grub.conf $ ls -l /etc/grub2.cfg lrwxrwxrwx. 1 root root 22 Dec 10 18:57 /etc/grub2.cfg -> ../boot/grub2/grub.cfg

  • /proc/net/dev and /sys/class/net/ bogus network interface names

    - by sfink
    I am constructing a list of network interfaces to monitor based on the contents of /proc/net/dev. But I am getting some bogus interfaces in the list: __tmp1104705027 __tmp974528607 Where do those come from? They also show up in /sys/class/net/: # ls -1 /sys/class/net/ eth0 eth1 eth2 eth3 lo sit0 __tmp1104705027 __tmp974528607 For now, I think I'll just ignore anything starting with __tmp, but I'd like to know what they are and where they come from. This is on a recompiled CentOS 5.3 kernel: 2.6.18-128.7.1.el5.tvh.7PAE #1 SMP PREEMPT

  • Machine check events logged

    - by GoldenNewby
    In /var/log/messages, this error occurred: Sep 19 13:18:15 wdc kernel: [2772302.630416] Machine check events logged Shortly there after, the entire server became unresponsive. This is in the log of the Dom0 for a Xen Server (running the latest version on Debian Squeeze). Can anyone shed some light on what this error means? Should I be ordering new hardware? Edit: Also, it seems to imply it logged something, where can I find that?

  • MegaCLI always returns blank output

    - by JamesHannah
    This server is a Dell R200 running Ubuntu 8.04LTS using a LSI SAS1068E raid card supplied from Dell, I suspect that there might be some kind of RAID issue with the hardware raid built into the motherboard, but I can't seem to get MegaCLi to return any useful output: root@81 $ ./MegaCli -AdpAllInfo -aALL root@81 $ ./MegaCli -PDList -aALL root@81 $ The disks work and AFAIK the raid software is installed correctly. I've seen this issue on RedHat issues also in the past. The RAID was initially setup through the BIOS on this server and appears to be functioning fine apart from this.
