Description Willem Jan Withagen 2015-08-03 08:32:13 UTC
Created attachment 159484 [details] log ip-numbers for failed socket connect attempts Running ssh, logfiles are swamped with lines like: fatal: Read from socket failed: Connection reset by peer [preauth] Which is rather useless for tools like sshguard and/or fail2ban But this patch changes this info to: Aug 2 19:37:32 zfs sshd: Read from socket failed: 126.96.36.199 [preauth] Aug 2 19:37:32 zfs sshd:fatal: Read from socket failed: Connection reset by peer [preauth] I decided to keep the older log line as well, to keep consistent what was there already. I do not know if any logfile analysers care about this line. Thus giving other tools to opportunity to act on (now) known abuse ip-numbers. --WjW PS: not sure if the patch goes to FreeBSd, or perhaps upstream to openssh?
