• cups log kills ubuntu 12.04 and sudoer permissions changed

  - by peterretief

  I am using Ubuntu 12.04 as a desktop and recently had a weird crash with the log file for cups filling up the entire drive and not letting me back in, also what changed was /var/lib/sudo had changed from root to peter (me) I didn't make this change - I checked the history! I set the sudoers back to root and capped the max size for cups log Anyone had a similar experience? It feels like someone is messing around with my settings Is there any way to trace how the error occurred?

Any obvious ideas what can go wrong in this case? The most reasonable thing I can imagine is that the SSD is silently dropping some write requests, which eventually leads to an EXT4 filesystem inconsistency (but no disk I/O errors). How can this happen? Is there a relevant configuration option I should ensure to be set correctly? What tools should I use to diagnose the hardware failures? Would it be possible to diagnose the SSD failure without overwriting data?

• Debian amd64 on Dell Studio 540 reboot hangs

  - by Shcheklein

  Hi, I have Dell Studio 540 desktop and Debian Lenny installed on it: 2.6.26-2-amd64 #1 SMP Tue Mar 9 22:29:32 UTC 2010 x86_64 GNU/Linux The problem is that I can't reboot it.

• Registering publicly Mail server and Web server in a free dns server

  - by Bruno Vieira

  I'm trying to host the e-mails and the site of our company into our private server. I've already followed the Gentoo Virtual Mailhosting System with Postfix Guide and my mail server is working (actually it sends mails for the local users and for external users it goes to spam) and know how to set an Apache 2 server. What I don't know (and I mean really don't) is how to make them public. I did some research and found that I should ask my ISP to change the reverse DNS to my company domain in order to prevent my mails to be marked as spam, they are doing. I already know I have to configure a DNS Server, it seems like my register provider already has one but I don't know how I can configure CNET, A, MX, TXT and all those tags (Is it tags the name?) and If I must do some other configuration on my server. My Server: Linux mail 3.2.21-gentoo #1 SMP My /etc/hosts: 127.0.0.1 mail.example.com.br example example.com.br ::1 mail.example.com.br mail example.com.br My /etc/conf.d/hostname: hostname ="mail" What am I missing? If there's a guide about how to configure I would really be grate. Thanks in advance for the help. Cheers

• "Unable to initialize module" fileinfo php-pecl-Fileinfo.x86_64

  - by Myers Network

  I have a brand new server server that I am trying to get setup up. This is a 64 bit machine that I can not install "fileinfo" or "memcache". I have uninstalled these and reinstalled them using yum and pecl with no luck. Yum install fine "no error" but then get error when running php. pecl from what I can tell is only installing 32bit.

• Redis 2.0.3 would not let go of deleted appendonly.aof file after BGREWRITEAOF

  - by Alexander Gladysh

  Ubuntu 10.04.2, Redis 2.0.3 (more details at the end of the question). My AOF file for Redis is getting too large, to the point where it soon would threaten to take whole free disk space on my small-HDD VPS box: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda 32G 24G 6.7G 78% / $ ls -la total 3866688 drwxr-xr-x 2 redis redis 4096 2011-03-02 00:11 . drwxr-xr-x 29 root root 4096 2011-01-24 15:58 .. -rw-r----- 1 redis redis 3923246988 2011-03-02 00:14 appendonly.aof -rw-rw---- 1 redis redis 32356467 2011-03-02 00:11 dump.rdb When I run BGREWRITEAOF, the AOF file shrinks, but disk space is not freed: $ ls -la total 95440 drwxr-xr-x 2 redis redis 4096 2011-03-02 00:17 . drwxr-xr-x 29 root root 4096 2011-01-24 15:58 .. -rw-rw---- 1 redis redis 65137639 2011-03-02 00:17 appendonly.aof -rw-rw---- 1 redis redis 32476167 2011-03-02 00:17 dump.rdb $ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda 32G 24G 6.7G 78% / Sure enough, Redis is still holding the deleted file: $ sudo lsof -p6916 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME ... redis-ser 6916 redis 7r REG 202,0 3923957317 918129 /var/lib/redis/appendonly.aof (deleted) ... redis-ser 6916 redis 10w REG 202,0 66952615 917507 /var/lib/redis/appendonly.aof ...

• Very slow write performance on Debian 6.0 (AMD64) with DMCRYPT/LVM/RAID1

  - by jdelic

  I'm seeing very strange performance characteristics on one of my servers. This server is running a simple two-disk software-RAID1 setup with LVM spanning /dev/md0. One of the logical volumes /dev/vg0/secure is encrypted using dmcrypt with LUKS and mounted with the sync and noatimes flag. Writing to that volume is incredibly slow at 1.8 MB/s and the CPU usage stays near 0%. There are 8 crpyto/1-8 processes running (it's a Intel Quadcore CPU). I hope that someone on serverfault has seen this before :-(. uname -a 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux Interestingly, when I read from the device I get good performance numbers: reading without encryption: $ dd if=/dev/vg0/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 68.8951 s, 95.1 MB/s reading with encryption: $ dd if=/dev/mapper/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 69.7116 s, 94.0 MB/s However, when I try to write to the device: $ dd if=/dev/zero of=./test bs=64k 8809+0 records in 8809+0 records out 577306624 bytes (577 MB) copied, 321.861 s, 1.8 MB/s Also, when I read I see CPU usage, when I write, the CPU stays at almost 0% usage.

• Duplicity on a ReadyNAS

  - by Jason Swett

  Has anyone here run Duplicity on a ReadyNAS? I'm trying but here's what I get: duplicity full --encrypt-key="ABC123" /home/jason/ scp://[email protected]//gob Invalid SSH password Running 'sftp -oServerAliveInterval=15 -oServerAliveCountMax=2 [email protected]' failed (attempt #1) I've also found this post that says the "Invalid SSH password" message doesn't actually mean invalid SSH password. This would make sense because I'm not using an SSH password; I'm using a public key. I can ssh, ftp, sftp and rsync into my ReadyNAS just fine. (Actually, to be more accurate, I can get past authentication with ssh, ftp and sftp but I can't actually do anything past that. Regardless, that's enough to tell me that "Invalid SSH password" is bogus. Rsync works with no problems.) The post I found says the command will work as soon as the directory at the end of your scp command exists, but I don't know how to check for that. I know the share gob exists on my ReadyNAS and I know it's writable because I'm writing to it with rsync. Also, here is the verbose output: Using archive dir: /home/jason/.cache/duplicity/3bdd353b29468311ffa8485160da6873 Using backup name: 3bdd353b29468311ffa8485160da6873 Import of duplicity.backends.rsyncbackend Succeeded Import of duplicity.backends.sshbackend Succeeded Import of duplicity.backends.localbackend Succeeded Import of duplicity.backends.botobackend Succeeded Import of duplicity.backends.cloudfilesbackend Succeeded Import of duplicity.backends.giobackend Succeeded Import of duplicity.backends.hsibackend Succeeded Import of duplicity.backends.imapbackend Succeeded Import of duplicity.backends.ftpbackend Succeeded Import of duplicity.backends.webdavbackend Succeeded Import of duplicity.backends.tahoebackend Succeeded Main action: full ================================================================================ duplicity 0.6.10 (September 19, 2010) Args: /usr/bin/duplicity full --encrypt-key=ABC123 -v9 /home/jason/ scp://[email protected]//gob Linux gob 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 /usr/bin/python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39) [GCC 4.4.5] ================================================================================ Using temporary directory /tmp/duplicity-cridGi-tempdir Registering (mkstemp) temporary file /tmp/duplicity-cridGi-tempdir/mkstemp-ztuF5P-1 Temp has 86334349312 available, backup will use approx 34078720.

• lm-sensors - always returns 32 degrees (celsius) for temperature

  - by mopoke

  On my VIA EPIA motherboard (using VIA VT8231 ISA bridge), I get strange output for the lm-sensors temperature reading. It always returns 32 degrees (celsius). I have previously had correct output for temperature (my munin graphs show temperatures typically in the range of 50 to 60 degrees. I've tried uninstalling (and purging) the lm-sensors package, have re-run sensors-detect a number of times and rebooted but nothing seems to change the output. I am running Ubuntu Karmic Koala (9.10).

• How do I run a stable Windows XP kvm guest on Ubuntu 10.04?

  - by Jean-Paul Calderone

  I have three Windows XP guests running on a recently upgraded 64-bit Ubuntu 10.04 system. Occasionally (on the order of once every few days), one of the guests will become non-responsive and the kvm process on the host which is running that guest will start consuming 100% CPU. It will continue to do so until it is killed. When restarted, it will be fine for a while, and then the issue repeats. The kvm command line used to run all three guests is this: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1 -name bigdog21vmxp1 \ -uuid ea47ff84-125b-16f7-9a4d-a6d0d8bab46a \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/bigdog21vmxp1.monitor,server,nowait \ -monitor chardev:monitor \ -localtime \ -boot c \ -drive file=/var/lib/libvirt/images/windowsxp-1.qcow2,if=ide,index=0,boot=on,format=qcow2 \ -net nic,macaddr=54:52:00:02:06:0e,vlan=0,name=nic.0 \ -net tap,fd=58,vlan=0,name=tap.0 \ -chardev pty,id=serial0 \ -serial chardev:serial0 \ -parallel none \ -usb \ -usbdevice tablet \ -vnc 127.0.0.1:1 \ -k en-us \ -vga cirrus \ -soundhw es1370 Why do the systems misbehave this way sometimes? And what configuration can I change in order to fix it? Or, if the problem is due to a bug in kvm, what is the process for isolating a kvm failure so that the developers have a chance of fixing it?

• The RTL8111/8168B NIC under Linux and the r8168 driver

  - by nik

  So I've got one of the infamous R8168 Realtek ethernet NIC, which have some problems under Linux. After some research, I found out I had to use the r8168 driver for this card (and not the r8169 which still loads when nothing else is available), which I did. So now everything works fine... Sort of. My download and upload rates are more than halved compared to what I should get. When I test (with eg. speedtest) I get something like 20M (often 15M) in download and 30M in upload, but if I test under Windows (everything is otherwise identical: same ethernet cable, same connection, at the same time of the day (well 5 min apart)...), I get 50M upload/download (which is what I expect). Where can it come from? Here's some info: ~ # lspci [...] 06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Uninstall Perl 5.10 and Install 5.8 on Ubuntu 10.04

  - by user48848

  I was using Ubuntu 8.04 with installed Perl 5.8.8. I had installed Bugzilla 3.4.4 with some custom scripts and it was working fine. I had to upgrade Ubuntu from 8.04 to 10.04 and automatically Perl is also upgraded from Perl 5.8 to 5.10. Now, accessing Bugzilla displays an error message related to Perl module. While trying to run checksetup.pl, I am getting the following error message: root@cvsnew:/var/www/bugzilla-3.4# perl checksetup.pl * This is Bugzilla 3.4.3 on perl 5.10.1 * Running on Linux 2.6.32-24-generic-pae #39-Ubuntu SMP Wed Jul 28 07:39:26 UTC 2010 Checking perl modules...

I explored this issue and found that this issue has come up because upgrading Ubuntu upgrades Perl 5.8 to 5.10 automatically. It seems like Perl 5.10.1 isn't binary compatible with the previous. Now, I want to uninstall Perl 5.10.1 and Install Perl 5.8.8 on my Ubuntu 10.04 box. I will appreciate if someone has already done that or share the required steps/commands to do it.

• PPP kernel module fails to load

  - by Harel

  I am trying to deal with a problem on a server I don't normally deal with. Out of the blue a script using ppp started failing saying that the ppp kernel module is not loaded. When I try to modprobe it it complains about files missing. Note below that the kernel version the server thinks it at, does not match the kernel version directory in /lib/modules. I'm not sure how this could have happened. Could the other maintainers of the server botched a kernel upgrade? My question is how can I fix this discrepancy. Can I simply rename the lib directory and hope for the best? I don't want to break stuff for the people who actually maintain the server but I do need to fix the PPP issue. $ sudo /sbin/modprobe -v ppp FATAL: Could not load /lib/modules/2.6.35.4-rscloud/modules.dep: No such file or directory $ cat /proc/version Linux version 2.6.35.4-rscloud ([email protected]) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #8 SMP Mon Sep 20 15:54:33 UTC 2010 $ ls /lib/modules/ 2.6.33.5-rscloud

• How to fix Apache from crashing with PHP+Curl on an SSH request?

  - by Jason Cohen

  My Apache process segfaults whenever I call curl_exec() from PHP with an "https://" URL. If I use http instead of https as the URL transport, it works perfectly, so I know curl and the other curl options are correct. I can use curl from the command-line on that server using the https version of the URL and it works perfectly, so I know the remote server is responding correctly, the cert isn't expired, etc..

• RPM issues after signing JDK 1.6 64-bit

  - by organicveggie

  I'm trying to sign the Java JDK 1.6u21 64-bit RPM on CentOS 5.5 for use with Spacewalk and I'm running into problems. It seems to sign okay, but then when I check the signature it seems to be missing the key I just used to sign it. Yet RPM shows the key in it's list... # rpm --addsign jdk-6u21-linux-amd64.rpm Enter pass phrase: Pass phrase is good. jdk-6u21-linux-amd64.rpm: gpg: WARNING: standard input reopened gpg: WARNING: standard input reopened # rpm --checksig -v jdk-6u21-linux-amd64.rpm jdk-6u21-linux-amd64.rpm: Header V3 DSA signature: NOKEY, key ID ecfd98a5 MD5 digest: OK (650e0961e20d4a44169b68e8f4a1691b) V3 DSA signature: OK, key ID ecfd98a5 Yet I have the key imported (edited for privacy): # rpm -qa gpg-pubkey* |grep ecfd98a5 gpg-pubkey-ecfd98a5-4caa4a4c # rpm -qi gpg-pubkey-ecfd98a5-4caa4a4c Name : gpg-pubkey Relocations: (not relocatable) Version : ecfd98a5 Vendor: (none) Release : 4caa4a4c Build Date: Mon 04 Oct 2010 10:20:49 PM CDT Install Date: Mon 04 Oct 2010 10:20:49 PM CDT Build Host: localhost Group : Public Keys Source RPM: (none) Size : 0 License: pubkey Signature : (none) Summary : gpg(FirstName LastName <[email protected]>) Description : -----BEGIN PGP PUBLIC KEY BLOCK----- Version: rpm-4.4.2.3 (NSS-3) ...key goes here... =gKjN-----END PGP PUBLIC KEY BLOCK----- And I'm definitely running a 64-bit version of CentOS: # uname -a Linux spacewalk.mycompany.corp 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:04:09 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux Without a valid signature, Spacewalk refuses to install the RPM unless I completely disable signature checking. I have tried this with two different keys and two different users on the same machine without any success. Any bright ideas?

• Debian: Should I add vlan interface into bridge for KVM?

  - by javano

  I am setting up a Debian Squeeze box as a KVM host. I want to add multiple interfaces to each KVM guest so I want them to be on different VLANs. After reading about this, I believe the best method is to add multiple logical VLAN (sub)-interfaces to the physical NICs and then create a bridge adapter for each VLAN interace, and assign each bridge as a NIC for KVM guests. Does this make good sense, or madness? Do I have to use bridged interfaces with KVM like this? Can't I just add eth1.xx and eth1.yy to my interfaces config below and then configure those directly as bridged KVM guest NICs? If so, how should this look in the interfaces config file below? user@host:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # Management Interface auto eth0 iface eth0 inet static address 172.22.0.31 netmask 255.255.255.0 gateway 172.22.0.1 # Interface for guest VMs auto eth1 # Guest1 : Use VLAN 117 auto eth1.117 iface eth1.117 inet manual # Set up br1 for guest 1, bridging with vlan 117 auto br1.117 iface br1.117 inet manual bridge_ports eth1.117 bridge_stp off user@host:~$ uname -a Linux hostname 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux UPDATE I would really like it if someone could clarify the config for me, as I have also seen the above configured with this syntax, so I don't see why one would be preferred over the other; # Interface for guest VMs auto eth1 allow-hotplug eth1 iface eth1 inet static # Vlan 117 for guest 1 auto vlan 117 iface vlan111 inet static vlan_raw_device eth1 # Guest 1 : NIC 1 auto br1.117 iface br1.117 inet manual bridge_ports vlan117 bridge_stp off
