Alas, yesterday I saw the contrib announcement about proftpd-chroot for SME6.5Rc1
I installed (via SSH since I'm at work during the day) and the internet broke down momentarily in the middle of rpm -Uvh . .
Since then my server has been unreachable from the outside.
Yesterday night I restarted it to get rid of eventual kinks originating from the breakdown, but to no avail.
Mail is still being processed, though, so its only external access that's been cut off completely.
Has anyone else experienced this ?
