I have a rb1100 that still has the crashing ssh server issue.

I have to VPN into it then connect via telnet.

It's a very heavily used router and I can't reboot it all the time just to fix it.

Please, send the following information to support@mikrotik.com

- support output file generated, when the problem is present;
- output from ssh -v -l admin x.x.x.x

Hi, have same problem.
You have a memory leak?

dimedrol, could you provide us with the same information?

dimedrol, we have replied to you in November and not received any feedback.

I think I have a similar issue. (5.0rc7 on a RB1100)

If I connect via SSH, and don't logout, but rather "exit" the terminal app (Mac OSX) then i'm unable to login again via SSH - I get a connection refused.

/ip service set ssh disabled=yes
/ip service set ssh disabled=no

fixes the problem, and I can login again. I suspect that since the SSH connection didn't exit cleanly, something gets hung.

Let me know if submitting a support outfile is of any use.

here's the output from "ssh -v" in the connection refused state.

$ ssh rb1100 -v

mdatic,
please contact support (support@mikrotik.com), we will give you pre-release package, where the problem is fixed (most likely).

I've also installed 5.0rc7 on two different devices this evening (RB1000 and RB1100), and although SSH was working at first, it is now failing for me too.
Any ideas how I can fix this?

I can confirm that enabling and disabling ssh temporarily fixes the issue for me too.

to follow up on this:

i've tested the pre-release package, and so far, it seems to resolve the issues i've had before with SSH.

Mikrotik just sent me the pre-release 5.0rc8, and this seems to have also fixed the SSH issues for me on the 2 devices I was testing - an RB1000 and RB110.
