It lets you create and remove individual instances with a specific user and port (if you specify them) and will install the required packages if not already present on the system.

In long, we use Clam AntiVirus as our antivirus protection for Digital Preservation Recorder and talk to it over the default port, 3310.

Installing the clamav-server package under Fedora however, doesn’t actually set up an instance. In fact, it doesn’t copy any system configuration files into place at all. This means that the system is left without any working ClamAV server out of the box.

Under Fedora, ClamAV server is configured on a per user basis. This is actually quite important (unless you run as root) because the daemon needs at minimum read access (and we’ve found also write) on the files/directory being passed for scanning.

The instructions on how to configure it are located under /usr/share/doc/clamav-server-[version]/ but I have taken these instructions and written a bash script to configure all of this for you.

The script is available from github. It can create or remove an individual instance of clamav-server using a specific username and port (if you want to specify them, else it defaults to clamav on port 3310). The script will also install any required packages, if you don’t already have them on the system.

Hopefully this is useful to someone else out there and not just us :-) If you find any bugs feel free to let me know.

I don’t want it to prompt me with questions, so I knew I had to set the priority to something higher for this specific package (i.e. temporarily). There doesn’t appear to be a way to pass this to an apt-get command (which was a little disappointing) but debconf can set it system wide under /var/cache/debconf/config.dat, but that’s, well, ugly.

Turns out there’s an environment variable you can set to achieve what I want, DEBIAN_PRIORITY. So exporting this variable and unsetting it post install will do the trick, but I still think apt-get -p critical install postfix would be better :-)
