Limit Bacula Network Usage with trickle

bacula is a great backupsoftware, but sometimes the backup mustn’t use all the available bandwith. bacula itself has no speed limitations built in, but it is easy, to use trickle to accomplish this. I use trickle only on the clients.

Installation

get trickle

yum install trickle

now enter /etc/init.d/bacula-fd and change the line which starts the daemon to the following:

# vim /etc/init.d/bacula-fd
... some lines ...
       daemon trickle -s -d 3000 -u 3000 /usr/sbin/bacula-fd $2 ${FD_OPTIONS} -c /etc/bacula/bacula-fd.conf
... some lines ...

trickle uses Kbyte in it’s commandline options, so with this settings, the up/down-Speed is limited to 3MB/s = 30MBit/s . Of course you can adjust this value as you like.

service bacula-fd restart

optional: does it work?

Now if you want to check if it works, just start a backup and monitor the traffic with bwm-ng for example

yum install bwm-ng

bwm-ng -t 1000

Compile asuro-Flash-Software under Ubuntu Linux 64bit

I was struggling some time compiling the asuro-Software under Linux 64bit. It simply did not recognise my installed qt3 libs. Some of these steps may not be necessary, but it’s how i got it to work.

Installing OTRS on CentOS 5

The rpm-packages for CentOS can easily be downloaded from http://otrs.org/download/ . Install with yum

wget http://ftp.otrs.org/pub/otrs/RPMS/fedora/4/otrs-2.4.5-01.noarch.rpm
yum install --nogpgcheck otrs-2.4.5-01.noarch.rpm

Don’t forget to disable selinux.

call in your browser http://yourserver.com/otrs/installer.pl and setup the database.

Now install the otrs cronjobs

sudo -u otrs /opt/otrs/bin/Cron.sh

this installs the otrs cronjobs in /var/spool/cron/otrs

Now you just have to setup basic otrs-stuff, like queues and Postmaster-configs. But everything over the otrs web interface.
