Dec 10 22:49:20 www sshd[31783]: Did not receive identification string from 61.175.252.139
A reverse IP lookup indicates that this ip address is:
CHINANET Zhejiang province network
Data Communication Division
China Telecom
CN
I'm running OpenSSH 3.0.2p1. Is there anything else that I should be doing to protect against whatever the ip address is trying to do?
Thanks,
Paul
