My Ubuntu server basically servers a Python Django site using Apache and Postgre. We SSH to it to configure some stuff from time to time but that's about it for the server. Since I'm trying to harden my installation, I'm trying to remove all useless processes and open ports. I've seen that there's something called
avahi-daemonrunning in the background:
avahi 1724 1 0 Jul20 ? 00:00:00 avahi-daemon: running [development.local] avahi 1726 1724 0 Jul20 ? 00:00:00 avahi-daemon: chroot helper
I've read that it has something to do with discovering other computers and printers on the same network. (I'm not entirely sure and that's even more the reason i feel the need to rid my os of it.)
Is this something important? Can I remove it? If so, how?
