Wind, fire, all that kind of thing!
Barracuda Networks provide agents for their backup appliance for various operating systems. Unfortunately the Linux agent (unlike the Windows agent) does not come with an option for a silent installation, and it doesn't look like the vendor can be bothered to do anything about it.
Instead of being able specify a path on the commandline (or at least force a silent installaton to the default path) you're always prompted for the path where the agent should be installed:
/tmp # tar xzf barracuda_backup_agent-x.x.x.tar.gz /tmp # cd barracuda_backup_agent-x.x.x /tmp/barracuda_backup_agent-x.x.x # ./install Please choose an installation path, or press enter for default. [/usr/local/barracuda/bbs]: _
Which kinda sucks when you're trying to automate agent deployment. However,
ps revealed that
install apparently is just a launcher for the actual installer located in the subdirectory
~ # ps afx ... 1437 tty1 Ss 0:00 /bin/login -- 1445 tty1 S 0:00 \_ -bash 1662 tty1 S+ 0:00 \_ sh -c "/root/barracuda_backup_agent-5.4.08//lin/x86_64/bblincin" 1663 tty1 Sl+ 0:00 \_ /root/barracuda_backup_agent-5.4.08//lin/x86_64/bblincin ...
And unlike the launcher that program at least accepts input from
STDIN, so you can specify the destination path by piping it into the program:
/tmp/barracuda_backup_agent-x.x.x # echo '/opt/bbagent' | ./lin/x86_64/bblincin Please choose an installation path, or press enter for default. [/usr/local/barracuda/bbs]: Installing to /opt/bbagent Stopping process bblingin Stopping process bblinagt Removing service Stopping process bblinsdr Copying file /opt/bbagent/lin/x86_64/bblincin Copying file bblincin ... Copying file /opt/bbagent/config/bbfilter.ini Copying file bbfilter.ini Installing service Starting service Install Complete!
Unattended uninstallation works the same way, except that you pipe
u instead of the destination path into the program:
echo 'u' | ./lin/x86_64/bblincin
