• How to prioritize openvpn traffic?

  - by aditsu

  I have an openvpn server, with one network interface. VPN traffic is extremely slow. I tried to do traffic control with this configuration (currently): qdisc del dev eth0 root qdisc add dev eth0 root handle 1: htb default 12 class add dev eth0 parent 1: classid 1:1 htb rate 900mbit #vpn class add dev eth0 parent 1:1 classid 1:10 htb rate 1500kbit ceil 3000kbit prio 1 #local net class add dev eth0 parent 1:1 classid 1:11 htb rate 10mbit ceil 900mbit prio 2 #other class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 1000kbit prio 2 filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 1194 0xffff flowid 1:10 filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match ip dst 192.168.10.0/24 flowid 1:11 qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 qdisc add dev eth0 parent 1:11 handle 11: sfq perturb 10 qdisc add dev eth0 parent 1:12 handle 12: sfq perturb 10 But it's still extremely slow. I have an imaps connection that keeps transferring data continuously (I successfully limited the rate) but with openvpn I can't seem to get more than about 100kbit/s The internet connection speed is about 3mbit/s (symmetric) What could be the problem? Does the sport filter work for udp?

• How to migrate a running KVM (with full disk copy) to another node?

  - by klipz

  I'm doing tests on KVM, and I'd like to see if I can make a hot migration, I mean the virtual machine won't stop running during the migration (but a few seconds of freeze is ok). I use a small cluster for my test : kvm1, kvm2, and kvmnfs. kvm1 and kvm2 runs the virtual machines kvmnfs is a NFS server, and it's mounted on /KVM on both kvm1 and kvm2 To migrate a VM (only RAM in fact) from kvm1 to kvm2, I run the same kvm command on kvm2 (with -incoming tcp:0:4444) that on kvm1, then I use "migrate -d tcp:kvm2:4444" : It works great, since the VM file is common to both machines. Now, I wan't to make a full migration (RAM + disk) of a local VM file (no more NFS) of kvm1 to kvm2. I tried to create an empty file, with touch, on kvm2 and use the same kvm command line + the "-incoming ..."). Then on kvm1 I use "migrate -d tcp:kvm2:4444" : It copies everything, then... the VM fails (any I/O disk gives an I/O error) ! And my VM file on kvm2, the one I created with touch, as still a size of 0 bytes. What am I doing wrong ? What is the exact command to use on kvm2 ? And what is the command to launch, in the monitoring mode, on kvm1 ?

• Permissions problems with Apache / SVN

  - by Fred Wuerges

  I am installed a SVN server (v1.6) on a VPS contracted with CentOS 5, Apache 2.2 with WHM panel. I installed and configured all necessary modules and am able to create and access repositories via my web browser normally. The problem: I can not commit or import anything, always return permission errors: First error: Can not open file '/var/www/svn/test/db/txn-current-lock': Permission denied After fix the previous error: Can't open '/var/www/svn/test/db/tempfile.tmp': Permission denied And other... (and happends many others) Can't open file '/var/www/svn/test/db/txn-protorevs/0-1m.rev': Permission denied I've read and executed permissions on numerous tutorials regarding this errors, all without success. I've defined the owner as apache or nobody and different permissions for folders and files. I'm using TortoiseSVN to connect to the server. Some information that may find useful: I'm trying to perform commit through an external HTTP connection, like: svn commit http://example.com/svn/test SELinux is disabled. sestatus returns SELinux status: disabled Running the command to see the active processes of Apache, some processes are left with user/group "nobody". I tried changing the settings of Apache to not run with that user/group, but all my websites stopped working, returning this error: Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

• Mounted HDD not having enough permissions from Apache/PHP

  - by Dan

  Piwigo gallery, on apache and php. The root system is a RAID 128GB. /var/www/html is on the root file system. Mounted the 320GB hdd to /var/www/html/320 using defaults, it's an ext4 fs. Put a symlink to it in /var/www/html/galleries which is read by the gallery script so I can upload images to there, then click sync. It gives me the error: [./galleries/] PWG-ERROR-NO-FS (File/directory read error) PWG-ERROR-NO-FS: The file or directory cannot be accessed (either it does not exist or the access is denied) chmod 777 set on /dev/sdb1, /var/www/html, and /var/www/html/320 as well as the symlink galleries too. All recursive. chown apache:apache to everything too. PHP just can't read/write to it. I tried with and without the symlink, I've tried everything I can think of. Nothing. Any ideas how I can give apache/php permission to read/write to this drive? With 777 permissions all around it should already be able to.

• How can I use the shell to make my mp3s a Shoutcast source?

  - by ChasonDehsotel

  I'm looking to stream a directory of mp3s from my audio source (Debian server) to my Shoutcast server. The idea is to have an archive playing in the instance that someone isn't broadcasting live. I'm not sure how to continue. I started with extensive Google-ing, and was unable to come up with a solution. Evan Carroll suggested I try here. I appreciate any insight y'all may have. __ On a side note, "users with less than 100 reputation can't create new tags. The tags 'shoutcast-source shoutcast broadcasting' are new. Try using existing tags instead." -- Who can create these?

• Courier Maildrop error user unknown. Command output: Invalid user specified

  - by cad

  Hello I have a problem with maildrop. I have read dozens of webs/howto/emails but couldnt solve it. My objective is moving automatically spam messages to a spam folder. My email server is working perfectly. It marks spam in subject and headers using spamassasin. My box has: Ubuntu 9.04 Web: Apache2 + Php5 + MySQL MTA: Postfix 2.5.5 + SpamAssasin + virtual users using mysql IMAP: Courier 0.61.2 + Courier AuthLib WebMail: SquirrelMail I have read that I could use Squirrelmail directly (not a good idea), procmail or maildrop. As I already have maildrop in the box (from courier) I have configured the server to use maildrop (added an entry in transport table for a virtual domain). I found this error in email: This is the mail system at host foo.net I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

• Load balancing with rsync

  - by David

  i have 2 server with public ip: SERVER A - 10.10.10.11 SERVER B - 10.10.10.12 both of them are centos 6 in OS, installed nginx with php-fpm, 2 exact same website stored at: /var/www/html. Domain with: myxdomain.com and dns hosted with cloudflare ( since cloudflare do support round robin ) to point the domain to A record of 10.10.10.11 and 10.10.10.12. I know that round robin dns does not cover the failover or fallover, but it does not matter, what i need is: How do i sync the both content of /var/www/html server A and server B to be exactly same? Lets say: 1) user uploaded their file to server A, the file content will be sync to server B as well. 2) user uploaded their file to server B, the file content will be sync to server A as well. rsync will be good choice here? Any example of command line and cronjob time that suitable? thanks

• CentOS default never fsck root partition on start up?

  - by wwwpanda

  Most documentation or sites will say use "tune2fs -l " to check if the system will do fsck on the system partitions on next boot, in particular, should look at "Mount count" and "Maximum mount count" values. However, I notice for default CentOS 5 or 6 installation, when I check against the root partition, I always noticed something like this from tune2fs output: ... Mount count: 91 Maximum mount count: -1 Last checked: Thu Oct 29 18:48:14 2009 Check interval: 0 (<none>) ... i.e. the max. mount count is set to "-1". That makes me wonder does it mean CentOS (or Red Hat) won't check the root partition at all? I check the fstab, the last number for root partition is still "1" as usual. If the OS does fsck the root partition during startup, how can I tell when (i.e. after how many reboots or when) will the OS will start fsck the root parition during startup?

• Unable to build Python modules in Mandriva 2010

  - by SteveJ

  I am trying to build a Python module (pyfits) but I get the following error: # python setup.py install /home/steve/src/pyfits-2.2.2/stsci_distutils_hack.py:239: DeprecationWarning: os.popen3 is deprecated. Use the subprocess module. (sin, sout, serr) = os.popen3(cmd) running install error: invalid Python installation: unable to open /usr/lib64/python2.6/config/Makefile (No such file or directory) I get the same error when I try and build other modules so my guess is I am missing a Python development library. I am running Mandriva 2010.0, any suggestions?

• Monitoring HP and Dell hardware in Gentoo.

  - by ewwhite

  I'm working in an environment that features a large number of Gentoo servers running on HP ProLiant and Dell PowerEdge equipment. While I've moved some of these systems to RedHat or CentOS for consistency, I'm still left with a good number of systems that will remain Gentoo. One of the issues I see with the Gentoo arrangement is lack of vendor-supported hardware monitoring. There doesn't seem to be an equivalent to the HP ProLiant Support Pack or Dell's agents for Gentoo. Is this simply something that you give up when using this distribution? How do you monitor hardware health and the like with Gentoo systems?

• Out of disk space on 4GB partiton yet it's only using 2GB

  - by Camsoft

  I'm running Ubuntu and have had a problem where the root partition has run out of disk space. When I perform df -h I get the following: Filesystem Size Used Avail Use% Mounted on /dev/sda6 4.6G 4.5G 0 100% / Yet there are only 2GB of files actually using up this partition. I then ran the following df -i and I get the following: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda6 305824 118885 186939 39% / I have no idea what the -i flag does but it clearly shows that only 39% is used. Can anyone explain where my disk space has gone?

• How to remove iso 9660 from USB?

  - by a_m0d

  I have somehow managed to write an iso 9660 image onto my USB drive, which makes all my computer think that the device is actually a CD. I have tried various methods of removing this partition, but nothing seems to work. I have tried fdisk, which says $ fdisk -l /dev/sdb Cannot open /dev/sdb parted crashes when I try to use it on this device. I have even tried $ dd if=/dev/zero of=/dev/sdb but it just hangs with no output (either on screen or on disk). However, when I plug the USB in, it does mount, and I can view (but not edit) the files on it. edit: now the result is $ dd if=/dev/zero of=/dev/sdb dd: opening `/dev/sdb': Read-only file system I have also tried re-formatting it on Windows, but it gets to the end of the format process and then says "Couldn't format the drive". How can I remove this partition and get my whole USB drive back to normal again? EDIT 1: Trying a simple mkfs doesn't work: $ sudo mkfs -t vfat /dev/sdb mkfs.vfat 3.0.0 (28 Sep 2008) mkfs.vfat: Will not try to make filesystem on full-disk device '/dev/sdb' (use -I if wanted) I can't do mkfs on /dev/sdb1 because there is no such partition, as shown:$ ls /dev | grep sdb sdb EDIT 2: This is the information posted by dmesg when I plug the device in:$ dmesg . .

• pxelinux hanging when booting client machine

  - by Blasphemophagher

  I'm kind of new to all of this, so please forgive any vagueness/misunderstandings on my part. I'm using pxelinux and VMs to create CentOS 6.0 machines that have the same install every time. I have a new VM set to boot from network, but in the process of booting up it gets stuck at "Loading 10.1.1.20:/pxelinux.0" (10.1.1.20 is the address of the server it's getting info from). pxelinux conf: http://pastebin.com/4XfZZPY1 I'm pretty sure all my config files are correct, could it be VirtualBox related? I have both the building server and the new client set to Host-only adapter and PCNET-FAST.

• 1 domain.. 2 server and 2 applications

  - by basit.

  i have a site like twitter.com on server one and on server two i have forum, which path is like domain.com/forum on server one i wanted to implement wild card dns and put main domain on it. but on server two i wanted to keep forum separate, i cant give sub-domain forum.domain.com, because all its links are already put in search engines and link back to domain.com/forum. so i was wondering, how can i put domain and wild card dns on server one and still able to give path on server 2 for domain.com/forum (as sub-folder). any ideas? do you think htaccess can do that job? if yes, then how?

• Securely wiping a file on a tmpfs

  - by Nanzikambe

  I have a script that decrypts some data to a tmpfs, the directory is secure (permissions), the machine's swap is encrypted (random key on boot) and when the script is done it does a 35 pass wipe (Peter Gutmann) of the cleartext on the tmpfs . I do this because I'm aware wiping files on a journaling file system is insecure, data may be recovered. For discussion, here're the relevant bits extracted: # make the tmpfs mkdir /mnt/tmpfs chmod 0700 /mnt/tmpfs mount -t tmpfs -o size=1M tmpfs /mnt/tmpfs cd /mnt/tmpfs # decrypt the data gpg -o - <crypted_input_file> | \ tar -xjpf - # do processing stuff # wipe contents find . -type f -exec bcwipe -I {} ';' # nuke the tmpfs cd .. umount -f /mnt/tmpfs rm -fR /mnt/tmpfs So, my question, assuming for the moment that nobody is able to read the cleartext in the tmpfs while it exists (I use umask to set cleartext to 0600), is there any way any trace of the cleartext could remain either in memory or on disk after the snippet above completes?

• What are some good, free tools to run automated security audits for PHP code?

  - by James Simpson

  I've been looking for some time now and have come up short. The most promising I found was Spike PHP, which seems to no longer work. I'm looking to scan my code for potential risks of SQL Injection, XSS, etc. I've gone through most of my code manually, but with a few hundred thousand lines of code, I'm sure I missed things. If possible, are there any tools that can be downloaded and analyze code on my local machine rather than installing to the live server (this isn't a requirement if not)?

• CentOS 5.5 installation on disk image

  - by Dima

  Today, in order to install CentOS 5.5 I'm using kickstart script. I would like to install CentOS on different way: Create disk image (using dd command) Create filesystem on this disk image using mkfs.ext3 Install CentOS on this filesystem Make this disk image bootable (using grub-install) Copy the disk image to the physical hard disk (using dd command) I know to do all these items except 3. Is it possible to do it? If yes, how can I install CentOS on the disk image?

• How come my Apache can't read my media folder, but it can load the site? (static files don't work)

  - by Alex

  Alias /media/ /home/matt/repos/hello/media <Directory /home/matt/repos/hello/media> Options -Indexes Order deny,allow Allow from all </Directory> WSGIScriptAlias / /home/matt/repos/hello/wsgi/django.wsgi /media is my directory. When I go to mydomain.com/media/, it says 403 Forbidden. And, the rest of my site doesn't work because all static files are 404s. Why? The page loads. Just not the media folder. Edit: hello is my project folder. I have tried 777 all my permissions of that folder.

• How to copy directories using debugfs?

  - by tjbp

  The debugfs manpage gives the impression that the command 'rdump . .' will recursively copy all files found on the specified filesystem from the debugfs cwd to the native filesystem's cwd. Instead I seem to receive a syntax error, and no copy is initiated? These are the commands I run: cd /path/to/transfer/destination debugfs /dev/sda1 -R rdump . . My task is to copy the entire contents of a clean yet unmountable USB storage device to its host machine's HD. The host machine does not support the inode size used by the USB device's filesystem (256) and its software is not upgradeable, so my intention was to use debugfs to transfer the files. If anyone has any other suggestions for this task I'd be grateful.

  Is there a way to place EXIM smtp banner on 1 line instead of 3 lines? The banner starts with 220. I've been searching but can not find a way. under /etc/exim.conf I have #todd host's smtp_banner = "${primary_hostname} ESMTP Exim ${version_number} \ \#${compile_number} ${tod_full} \n\ We do not authorize the use of this system to transport unsolicited, \n\ and/or bulk e-mail." do i make that one line?

• Is using Capistrano for user maintenance tasks on university lab feasible?

  - by danielkza

  I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

• Moving MySQL directory on an Amazon EC2 machine

  - by Traveling Tech Guy

  I'm trying to have MySQL point to a directory on an EBS volume I mounted on my EC2 machine. I took th following steps: Stopped MySQL (/etc/init.d/mysqld stop) - successful Created a MySQL directory on my volume, mounted on /vol (mkdir /vol/mysql) Copied the contents of /var/lib/mysql to /vol/mysql (cp -R /var/lib/mysql /vol/mysql) Chanded the owner and group of that directory to match the original (chown -R mysql:mysql /vol/mysql) - after this step, the 2 directories are identical. Edited the /etc/my.cnf file (commented 2 original lines): [mysqld] #datadir=/var/lib/mysql #socket=/var/lib/mysql/mysql.sock datadir=/vol/mysql socket=/vol/mysql/mysql.sock` Started MySQL (/etc/init.d/mysqld start) - FAILED The error file /var/log/mysqld.log contains the following lines: 100205 20:52:54 mysqld started 100205 20:52:54 InnoDB: Started; log sequence number 0 43665 100205 20:52:54 [Note] /usr/libexec/mysqld: ready for connections. Version: '5.0.45' socket: '/vol/mysql/mysql.sock' port: 3306 Source distribution No other errors are available. What am I doing wrong? Where can I find the error/s encountered by MySql? If I restore the original lines, MySQL starts, leading me to believe it may be a permissions issue - but permissions are the same for both directories? Thanks!
