Large Number of Failed Login from server ITSELF




Posted by astraeuz, 06-19-2011, 02:22 PM
Hi, I've enable cPHulk Brute Force Protection on the server so it notifies me of the suspicious activity. BUT, what made me worry is that the email I received mentions that the failed login attempt was made from the server itself and no mention of the IP address... ------------------------------------------------------------ Subject: Large Number of Failed Login Attempts from IP christopher Msg Body: 2 failed login attempts to account christopher (system) -- Large number of attempts from this IP: christopher (no IP) Reverse DNS: www.serveraddr.com ------------------------------------------------------------ can someone comment on what could be the issue?

Does it say that "2" is a large number of bad logins?

Hi, That happened to me once, I never found out what the problem was. Maybe a website pinging it? - Im not too sure Dylan, RadicalBro

that is WHM bruteforce(cpHulkd) protection but your thresshold seems a bit tight use something like logcheck that will give you more information you can configure that in whm security...

Hey , Check your cpanel and message log files at /usr/local/cpanel/logs/login_log and /var/log/messages to see failed login attempts . Its possible to have a php shell uploaded and then trying to do dictionary attack to the server for which it might say the host as localhost in this case as you have mentioned.
