Lost SSH access

rp1783 · 19. November 2014

I installed OMV on a WD Mycloud device. I also installed NZBGet and added a startup script at /etc/init.d/nzbget.

After I did this, I was attempting to change the SSH port and got the following error:

Code

Now, I'm getting a connection refused message using Putty. Anything I can do to fix this?

Try uninstalling nzbget.

Sorry for my ignorance, but what is the method I should use to uninstall if I don't have ssh access?

Can you get in the web gui of OMV???? Were you trying to change the port of ssh in command line??? You can do that in OMV's web gui.

rp1783 · 19. November 2014

I was trying to change the port via the gui. The error I received when trying to make the change is in the OP, and now I can't access via ssh. I can still get into the gui.

Did you install nzbget via plugin or command line? I thought you used the plugin. That is why I told you to uninstall it using the web interface.

If you install webmin you can edit files on the system drive with it's file manager. Then you can reboot. But first you need to know what to edit. It is probably something to do with the /etc/ssh/sshd_config file. Change the port in that file back to 22, if it is not 22, and reboot.

Aaron, version upgrade the mediabrowser plugin please.

You can use the scheduled jobs to try and run commands.
You can try update-rc.d nzbget disable, update-rc.d nzbget remove, rm /etc/init.d/nzbget

Great idea You could also try to start ssh that way - service ssh start

The ssh service is crooked by improper lsb headers using a custom non-verified script

As a temp solution fire a side sshd server

execute in scheduled task

/usr/sbin/sshd -p 2000 &

and enter ssh in port 2000

This worked for me. Thank you so much.
