https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218925 Bug ID: 218925 Summary: 800.loginfail needs more info on some ssh login failures Product: Base System Version: 11.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: dwmcrobb@me.com Created attachment 182143 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D182143&action= =3Dedit patch to pick up more useful ssh login failure data from auth.log I regularly get this kind of mail from the daily security run on public-fac= ing machines: Apr 26 06:00:50 ria sshd[31509]: Disconnecting: Too many authentication failures [preauth] Apr 26 06:49:03 ria sshd[31583]: Disconnecting: Too many authentication failures [preauth] Apr 26 06:56:49 ria sshd[31627]: Disconnecting: Too many authentication failures [preauth] Apr 26 07:45:25 ria sshd[31715]: Disconnecting: Too many authentication failures [preauth] Apr 26 09:28:19 ria sshd[31890]: Disconnecting: Too many authentication failures [preauth] Apr 26 09:59:13 ria sshd[31952]: Disconnecting: Too many authentication failures [preauth] Apr 26 11:16:29 ria sshd[32092]: Disconnecting: Too many authentication failures [preauth] Apr 26 12:52:50 ria sshd[32457]: Disconnecting: Too many authentication failures [preauth] Apr 26 15:29:09 ria sshd[33415]: Disconnecting: Too many authentication failures [preauth] Not very helpful. I should be seeing this: Apr 26 06:00:50 ria sshd[31509]: error: maximum authentication attempts exceeded for root from 188.187.52.118 port 49171 ssh2 [preauth] Apr 26 06:00:50 ria sshd[31509]: Disconnecting: Too many authentication failures [preauth] Apr 26 06:49:03 ria sshd[31583]: error: maximum authentication attempts exceeded for root from 87.198.39.108 port 45609 ssh2 [preauth] Apr 26 06:49:03 ria sshd[31583]: Disconnecting: Too many authentication failures [preauth] Apr 26 06:56:49 ria sshd[31627]: error: maximum authentication attempts exceeded for root from 190.216.171.66 port 39053 ssh2 [preauth] Apr 26 06:56:49 ria sshd[31627]: Disconnecting: Too many authentication failures [preauth] Apr 26 07:45:25 ria sshd[31715]: error: maximum authentication attempts exceeded for root from 62.20.61.178 port 40532 ssh2 [preauth] Apr 26 07:45:25 ria sshd[31715]: Disconnecting: Too many authentication failures [preauth] Apr 26 09:28:19 ria sshd[31890]: error: maximum authentication attempts exceeded for root from 112.250.104.128 port 43618 ssh2 [preauth] Apr 26 09:28:19 ria sshd[31890]: Disconnecting: Too many authentication failures [preauth] Apr 26 09:59:13 ria sshd[31952]: error: maximum authentication attempts exceeded for root from 202.100.182.254 port 54912 ssh2 [preauth] Apr 26 09:59:13 ria sshd[31952]: Disconnecting: Too many authentication failures [preauth] Apr 26 11:16:29 ria sshd[32092]: error: maximum authentication attempts exceeded for root from 71.227.146.158 port 60455 ssh2 [preauth] Apr 26 11:16:29 ria sshd[32092]: Disconnecting: Too many authentication failures [preauth] Apr 26 12:52:50 ria sshd[32457]: error: maximum authentication attempts exceeded for root from 77.37.232.131 port 39678 ssh2 [preauth] Apr 26 12:52:50 ria sshd[32457]: Disconnecting: Too many authentication failures [preauth] Apr 26 15:29:09 ria sshd[33415]: error: maximum authentication attempts exceeded for root from 78.194.25.54 port 49924 ssh2 [preauth] Apr 26 15:29:09 ria sshd[33415]: Disconnecting: Too many authentication failures [preauth] Even better would be: Apr 26 06:00:50 ria sshd[31509]: error: maximum authentication attempts exceeded for root from 188.187.52.118 port 49171 ssh2 [preauth] Apr 26 06:49:03 ria sshd[31583]: error: maximum authentication attempts exceeded for root from 87.198.39.108 port 45609 ssh2 [preauth] Apr 26 06:56:49 ria sshd[31627]: error: maximum authentication attempts exceeded for root from 190.216.171.66 port 39053 ssh2 [preauth] Apr 26 07:45:25 ria sshd[31715]: error: maximum authentication attempts exceeded for root from 62.20.61.178 port 40532 ssh2 [preauth] Apr 26 09:28:19 ria sshd[31890]: error: maximum authentication attempts exceeded for root from 112.250.104.128 port 43618 ssh2 [preauth] Apr 26 09:59:13 ria sshd[31952]: error: maximum authentication attempts exceeded for root from 202.100.182.254 port 54912 ssh2 [preauth] Apr 26 11:16:29 ria sshd[32092]: error: maximum authentication attempts exceeded for root from 71.227.146.158 port 60455 ssh2 [preauth] Apr 26 12:52:50 ria sshd[32457]: error: maximum authentication attempts exceeded for root from 77.37.232.131 port 39678 ssh2 [preauth] Apr 26 15:29:09 ria sshd[33415]: error: maximum authentication attempts exceeded for root from 78.194.25.54 port 49924 ssh2 [preauth] A minor change (attached) will at least get the lines that are useful (and = also the cruft but I can live with that), and I don't believe it will muck up the recognition of other login failures. --=20 You are receiving this mail because: You are the assignee for the bug.=
