RB 1100 lock service SSH OS V. 5.20

Good Morning

We have a problem and can not identify, we have a 1100 RB RouterOS V. 5:20 doing PPPOE authentication, 200 simultaneous users.
We use a check where our need to make a SSH server, however within two days it does not happen again, I can not open terminal or internal. The RB does not lock but does not run over SSH.
Could you help me? :confused:

Nobody can help???

see http://forum.mikrotik.com/t/problems-ssh-and-terminal-x86-ros-5-18-and-up/59296/1 but no answer from support(((

I have the same problem (no PPPoE, but over 150 PPTP users, 10-20 simultaneously active). 2-3 days uptime everything is OK, then terminal and ssh stop working.

What most amazed me, I wanted to generate supout file to attach to support mail, and just after clicking “Make supout.rif” in Winbox everything immediately went back to normal. Do this: open terminal window, observe that it doesn’t work then click “Make supout.rif”. The prompt appears after 1-2 sec, and subsequent terminal windows are most of the time ok – however after 14 or more days of uptime that hack may not help.

And the reboot can be fragile too, it can panic during reboot.

Does any of support team reading this)( ?
It`s very bad to reboot router in production area

Hello,

I just upgraded my router from 5.18 to 5.21 and I cannot connect to my router via SSH anymore. It was working perfectly fine for years before the upgrade. Now, I only get following error on my SSH client

ssh_exchange_identification: Connection closed by remote host

Any help to solve this ?

Thx

I’ve got this on an x86 box that does not do pppoe or pptp. your trick fixes it.

For some reason, I haven’t noticed that the security package has not been upgraded! So, I uploaded it again, and now no more problems with the ssh connection.

So, check that the security package is still there after an upgrade. And I 100% sure I did upload it before upgrading from 5.18 to 5.21.

Checked, and every affected router has all packages versions 5.21. I don’t upload each package separately, but use one .npk file to upgrade all at once.

From some strange reason npk for 5.21 does not install security package.
workaround: install security package from zip file.
upgrade from 5.20 to 5.21
X86 system
other packages where not installed as well.
List of missing packages after upgrade:
security
routing
mpls
advanced-toolsmulticast
user-manager
wireless
ppp
ntp
lcd
kvm
gps
