How To Stop Server Attacks
I keep on getting messages like this all the time. Does anyone know how to stop these people from trying to bruteforce their way into my server?
The messages seem to always come from China and it's always the same computer name "ylmf-pc". Does anyone know how to ban traffic coming from computers with the name "ylmf-pc"? or any other way of stopping them. ======================================== Time: Wed Jul 6 02:22:00 2011 -0400 IP: 123.68.178.75 (CN/China/-) Failures: 5 (smtpauth) Interval: 300 seconds Blocked: Permanent Block Log entries: 2011-07-06 02:21:40 dovecot_login authenticator failed for (ylmf-pc) [123.68.178.75]: 535 Incorrect authentication data (set_id=administrator) 2011-07-06 02:21:44 dovecot_login authenticator failed for (ylmf-pc) [123.68.178.75]: 535 Incorrect authentication data (set_id=administrator) 2011-07-06 02:21:48 dovecot_login authenticator failed for (ylmf-pc) [123.68.178.75]: 535 Incorrect authentication data (set_id=administrator) 2011-07-06 02:21:52 dovecot_login authenticator failed for (ylmf-pc) [123.68.178.75]: 535 Incorrect authentication data (set_id=administrator) 2011-07-06 02:21:56 dovecot_login authenticator failed for (ylmf-pc) [123.68.178.75]: 535 Incorrect authentication data (set_id=administrator) ======================================== Have you become an employee to your own business by chasing first page google rankings on a daily basis?
