Hi Greg

Any thoughts?


type=Single
ptype=RegExp
pattern=^\S+\s+\d+\s+\S+\s+(\S+)\s+proftpd\[\S+\]: \S+ \(\S+\[(\S+)\]\) - \S+ \S+ \(Login failed\): Incorrect password.
desc=$0
action=event BLOCK, $2, proftpd-b4

This is the rule that is getting matched. Basically, its a FTP incorrect password in /var/log/secure .... Find out whats doing the FTP jobs with the bad password, and problem fixed :)

Greg.

As you can see from my logs this is blocking me every day. I haven't used FTP on this server EVER! :)

My main access is either SSH or GUI and that is only probably a couple of times a month if that.

Something weird is going on.

Thanks

Colin

Something is a amiss.

Hi Greg,

Check out /var/log/sec ... this is the log file for dfix2. Look for the IP in that file
and send me details of what you find. That will help to understand why a
particular IP is getting blocked.

Well here is a result (sort of) ... I've been blocked this morning and I haven't been near it! :)
