SSH to MT 2.9 generates log errors - bug?

RouterOS General
1

I’ve recently upgraded a MT Hotspot to 2.9.10. I’ve got a Linux box running Cacti that has a script that logs into this Hotspot every 5 minutes to gather statistics. Since upgrading from 2.8.28 to 2.9.10 (actually, this is a fresh install with a fresh config) I’ve noticed that any SSH session I open to this MT router generates this the following log error:

15:07:36 system,error,critical login failure for user test from 1.2.3.4 via ssh

followed by:

15:07:40 system,info,account user test logged in from 1.2.3.4 via ssh 
15:07:49 system,info,account user test logged out from 1.2.3.4 via ssh

Further testing shows that if I “ssh test@1.2.3.4” and get prompted for the password, that it aways generates an error in the log first.

Is this a bug? Is there a way to prevent the log error without turning off that part of the logging all together?

There was a forum post about this a few weeks back. If your ssh client tries with a blank password first you will see that attempt.

Thanks for the reply. Haven’t had a chance to find out how to turn this off yet, but at least I know…
