Repeated Log Entry: sshd: authentication failure; logname= uid=0


Running RH9

I'm seeing the following repeatedly in my messages log.

Oct 7 11:36:24 360pro sshd(pam_unix)[26784]: authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser=

Forgive my ignorance but is this a failed ssh atempted? If so, what concerns should I have based on the entry and is there a way to block it?

I get literally hundreds of those each day on both of my servers. They are failed login attempts, probably from some a-hole who just did a port scan and noticed you were listening on port 22. As long as you have strong user passwords and restrict root ssh access you should be fine.
