  • query keepalived

    - by tdimmig
    *Note: I have trouble deciding what should go in serverfault and what should go in superuser, if some kindly admin decides this is in the wrong place please move it for me - many thanks. I am implementing a basic HA system with keepalived. I only want to be notified of the failover in the case of hardware failure. I do, however, have the servers switch roles periodically. I have a track_script running on the backup that will vary it's return between 0 and 1 on an interval (once a week, once a month, whatever). Upon returning 0, the priority is raised above that of the master, upon returning 1 the priority is lowered again. This way they trade places on the configured interval. The question: What can I do to tell the difference between a switch caused by my script, and a switch caused because one of the servers died? I certainly want to be notified when there is an actual problem, but not every time the servers change places because of the script. I see that version 1.2.7 has snmp support and I may be able to use it to get some information that could tell me one way or another, but to be honest I've never used snmp before and I don't know how to get the information I want with it (my Google foo failed me).

  • USB webcam just works once and next time I've to reboot

    - by user30262
    I'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb. The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again. Has anyone else noticed this behaviour? Is there some good solution to reset the camera without rebooting to make it work again?

  • disable specific PCI device at boot

    - by Rhymoid
    I've just reinstalled Debian on my Sony VAIO laptop, and my dmesg and virtual consoles all get spammed with the same messages over and over again. [ 59.662381] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 59.901732] usb 1-1.2: new high-speed USB device number 91 using ehci_hcd [ 59.917940] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 60.157256] usb 1-1.2: new high-speed USB device number 92 using ehci_hcd I believe these messages are coming from an internally connected USB device, most likely the webcam (since that's the only thing that doesn't work). The only way I can seem to have it shut up (without killing my actually useful USB ports) is to disable one of the USB host controllers: # echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci_hcd/unbind This also takes down my Bluetooth interface, but I'm fine with that. I would like this setting to persist, so that I can painlessly use my virtual console again in case I need it. I want my operating system (Debian amd64) to never wake it up, but I don't know how to do this. I've tried to blacklist the module alias for the PCI device, but it seems to be ignored: $ cat /sys/bus/pci/devices/0000\:00\:1a.0/modalias pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 $ cat /etc/modprobe.d/blacklist blacklist pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 How do I ensure that this specific PCI device is never automatically activated, without disabling its driver altogether? -edit- The module was renamed recently, now the following works from userland: echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci-pci/unbind Still, I'm looking for a way to stop the kernel from binding that device in the first place.

  • Getting PAM/user info into php - something like Net_Finger instead of a db?

    - by digitaltoast
    I've got a very small user group who just need to login, upload, check and then move specific files to a different area when ready. Right now, I use the nginx PAM auth module to log them in against their unix accounts. As their login is their home directory, I've already got the info to send the uploads to the right area - one line of php and no database needed. But I'm maintaining a separate DB just so PHP can welcome them, grab their email and send them an email when processed. Yes, sure I could use nosql or sqlite instead so as to not need a whole mysql install. But it occurred to me that as I've got all these blank user fields for phone numbers I could populate with any data, that I could use something like php's Net_Finger. Which failed for me with: sudo pear install Net_Finger Starting to download Net_Finger-1.0.1.tgz (1,618 bytes) ....done: 1,618 bytes could not extract the package.xml file from "/build/buildd/php5-5.5.9+dfsg/pear-build-download/Net_Finger-1.0.1.tgz" Download of "pear/Net_Finger" succeeded, but it is not a valid package archive Error: cannot download "pear/Net_Finger" At which point I thought I'd stop, and take a ServerFault reality check - is this a really bad/dangerous/stupid idea just to stop me having to maintain details in two places rather than one? It there a better way? Googling shows that it's not an oft-asked thing, so perhaps with good reason?

  • Confused about setting up subversion

    - by apache
    I've already compiled and installed subversion, now trying to add users to it. And I find two articles on this, but they seem to be going in entire different direction. The 1st is here, which looks very simple, and seems it's not necessary to create a user account(useradd ...) the 2nd is here, which is a lot more complicated, and seems I need to create a user account for each svn user. Which one should I follow?

  • DHCP server can't see other machines

    - by William
    Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

  • I can connect to Samba server but cannot access shares.

    - by jlego
    I'm having trouble getting samba sharing working to access shares. I have setup a stand-alone box running Fedora 16 to use as a file-sharing and web development server. It needs to be able to share files with a Windows 7 PC and a Mac running OSX Snow Leopard. I've setup Samba using the Samba configuration GUI tool on Fedora. Added users to Fedora and connected them as Samba users (which are the same as the Windows and Mac usernames and passwords). The workgroup name is the same as the Windows workgroup. Authentication is set to User. I've allowed Samba and Samba client through the firewall and set the ethernet to a trusted port in the firewall. Both the Windows and Mac machines can connect to the server and view the shares, however when trying to access the shares, Windows throws error: 0x80070035 " Windows cannot access \\SERVERNAME\ShareName." Windows user is not prompted for a username or password when accessing the server (found under "Network Places"). This also happens when connecting with the IP rather than the server name. The Mac can also connect to the server and see the shares but when choosing a share gives the error: The original item for ShareName cannot be found. When connecting via IP, the Mac user is prompted for username and password, which when authenticated gives a list of shares, however when choosing a share to connect to, the error is displayed and the user cannot access the share. Since both machines are acting similarly when trying to access the shares, I assume it is an issue with how Samba is configured. smb.conf: [global] workgroup = workgroup server string = Server log file = /var/log/samba/log.%m max log size = 50 security = user load printers = yes cups options = raw printcap name = lpstat printing = cups [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = yes printable = yes [FileServ] comment = FileShare path = /media/FileServ read only = no browseable = yes valid users = user1, user2 [webdev] comment = Web development path = /var/www/html/webdev read only = no browseable = yes valid users = user1 How do I get samba sharing working? UPDATE: I Figured it out, it was because I was sharing a second hard drive. See checked answer below. Speculation 1: Before this box I had another box with the same version of fedora installed (16) and samba working for these same computers. I started up the old machine and copied the smb.conf file from the old machine to the new one (editing the share definitions for the new shares of course) and I still get the same errors on both client machines. The only difference in environment is the hardware and the router. On the old machine the router received a dynamic public IP and assigned dynamic private IPs to each device on the network while the new machine is connected to a router that has a static public IP (still dynamic internal IPs though.) Could either one of these be affecting Samba? Speculation 2: As the directory I am trying to share is actually an entire internal disk, I have tried these things: 1.) changing the owner of the mounted disk from root to my user (which is the same username as on the Windows machine) 2.) made a share that only included one of the folders on the disk instead of the entire disk with my user again as the owner. Both tests failed giving me the same errors regarding the network address. Speculation 3: Whenever I try to connect to the share on the Windows 7 client I am prompted for my username and password. When I enter the correct credentials I get an access denied message. However I did notice that under the login box "domain: WINDOWS-PC-NAME" is listed. I believe this could very well be the problem. Speculation 4: So I've completely reinstalled Fedora and Samba now. I've created a share on the first harddrive (one fedora is installed on) and I can access that fine from Windows. However when I try to share any data on the second disk, I am receiving the same error. This I believe is the problem. I think I need to change some things in fstab or fdisk or something. Speculation 5: So in fstab I mapped the drive to automount in a folder which works correctly. I also added the samba_share_t SElinux label to the mountpoint directory which now allows me to access the shares on the Windows machine, however I cannot see any of the files in the directory on the windows machine. (They are there, I can see them in the fedora file browser locally)

  • Binding MySQL to run from the public or private LAN IP address - which one is faster

    - by Lamin Barrow
    So we have 2 servers all running at the same web host. We have bind MySQL to listen on the public ip-address of the database server and the web server connects to it from the public ip. Both servers run on the same private network. Currently, the DB connect method from our php script takes about 3ms to connect to the MySQL database server host. My question is, would MySql data interaction from the web server be faster if we bind it to listen on the private lan address on the database server instead of the public IP? or is it the same regardless and it wont make a different.

  • Tool to allow Kerberos Authenticated users to modify Firewall settings

    - by Lars Hanke
    I run a firewall on a central router. Recently, several users want to use Skype. Since firewalling Skype virtually means to switch the firewall off, I consider to allow users to temporarily punch holes for their system. Since the users have no accounts on the router, I consider using Kerberos for authentication and authorization. The router is a Debian Squeeze box, with minimal configuration, i.e. no web-server, database or similar gimmicks. Does anyone know an existing solution, which could be used for that purpose? Or does anybody know easy to use and well documented frameworks in say Perl, Python, C, C++, ... making the set-up of a Kerberos authenticated Client and Server application really simple?

  • VPS stops responding every now and again

    - by Or W
    I have a Linode vps that I use to host some of my websites on. It's Ubuntu based and it's up to date in terms of all packages. I don't have any cron jobs scheduled or any automatic processes. I host a few (up to date) wordpress blogs there that have very little traffic altogether. Every day (at a different time) my server stops responding, I can't SSH to it, web access is getting timed out and it just dies until I reboot it through the Linode manager. On the linode dashboard I can see that the CPU is not very high (2-3%) Incoming/Outgoing traffic is on 0 and the IO count has a spike just before the server stops responding (SWAP IO is at 2k and IO Rate is at 5k). When I reboot the server everything is just fine. I'm trying to figure out a way to analyze what's going on at these random times where the server freezes up. How can I determine the problem?

  • How to serve a .php file locally?

  • Hard Reset USB in Ubuntu 10.04

    - by Cory
    I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: $ sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: $ sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on serverfault as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

  • Better way to quad+ boot operating systems?

    - by Wijagels
    I currently have Windows 7, Ubuntu 12.04, Fedora 17, and open SUSE installed. I currently use BURG boot loader to load up all the systems. However, BURG does not work with windows(I still manage) and it is a little finicky. So, I want to make windows work and have all the other OSes I want all on one boot loader. I already tried easy BCD and for whatever reason Fedora took over and blocked out the other OSes.

  • How do I minimize Evolution to the system tray in Ubuntu?

    - by Jephir
    In Ubuntu some applications can be set to minimize instead of exit on close. For example, Empathy minimizes to the system tray (mail icon) when the close button is pressed in the application window. How do I make Evolution do this as well? Essentially I would like to have Evolution hidden in the system tray instead of having to re-launch it every ten minutes to check for new messages (or leave it open and clutter the taskbar).

  • Ubuntu server users question

    I have read this article: https://help.ubuntu.com/9.04/serverguide/C/user-management.html But it doesn't go into depth with the privileges section. I need to know how to set privileges of me (as a user). I am the only user, but I want access to everything, but I don't want to manage my VPS logged in as root. So I am creating a username. Anybody have a list of privileges, what they mean and how to set them? Thanks

  • Why does everybody have the same MAC address as me?

    - by iblue
    I just bought some consumer-grade McCheap PCI-E NICs (and this was a bad idea). They both have the same MAC address. When I google it, it seems like every card of that company has the same address: 00:50:43:00:45:3e. Shouldn't they be unique? According to lspci it's a Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20). Is there a way to permanently flash a new address?

  • Reading a file from an alternate location

    - by Highstaker
    I have a certain file (data.abc) located in, say, my home folder. I make a copy of it to another location (for example, "/mnt/ramtemp/"). Whenever the file in my home folder is accessed by any process, I want it to be read not from home folder, but from "/mnt/ramtemp/". As you might have guessed from the path of the latter, it is where I mount the ramfs. So, basically, I want a process to access not the file on my HDD (which is slower), but its copy on ramfs (which is way faster). At the same time, I want the file data.abc to remain in my home folder under that name, I don't want to rename or delete it. Is there any way I could guide the system to redirect the processes to read the file from alternative location whenever they try to read it from home folder?
