scanlogd requires a seperate user and group named 'scanlogd' to run. You will need to create these manually. Add a group: groupadd scanlogd then find its gid: grep scanlogd /etc/group | cut -f3 -d':' Now list all the uids to find the highest in use: cut -f3 -d':' /etc/passwd add 1, and add the user with that uid and the gid added above: chpass -l -a "scanlogd:*:$uid:$gid:::::/nonexistent:/sbin/nologin" The scanlogd program will automatically switch to this user upon startup.
