Did you setup a ssh connection between a client and a PostgreSQL server? No, I didn't. Or, at least, it's possible I connected to a uni ssh server that also runs PostgreSQL, but if I did, it certainly wasn't to do anything database-like. I'd just have been using it as a tunnel to another machine, which isn't running PostgreSQL. Is this another incoming attack? Probably not, does posqresql have a homedir in /var/lib/pgsql? grep pgsql /etc/passwd postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash I would bet sshd is just looking through homedirs as listed in /etc/passwd We have a fix in Fedora18. Backported.
