Hi,
it's known issue, look here: https://www.turris.cz/doc/en/troubleshooting/erratum

Od peter Dne 2016-10-06 15:48

Oh, I see!
Thanks

But I would have to do a factory reset to fix the issue?
And when done with factory reset, how do I know it's gonna work/what do I have to do differently?

https://www.turris.cz/doc/en/troubleshooting/erratum says:
"... or log in to Omnia via serial cable and enter the following command rm /etc/ssh/ssh_host_* to fix this issue."

By reseting the router you would loose everything you did on the box so far ...

But how is that done?

On the original versions of Turris there is a micro-USB port for serial console access (hidden inside the box in Turris 1.0). Omnia will have such a port as well. Unfortunately I have no idea where as I'm still waiting for my box :sad:

.... maybe it's one of the two USB-A ports (front/back)? To access it you'll need a console application (for example minicom on Linux or PuTTY on Windows)

I'll give it a try! :smile:

Thanks

Another way is to let the router start. You should access http interface (luci) of the router. Enter commands to the System->Custom commands and run it from the web interface.

Od peter Dne 2016-10-06 16:20

Oh yeah, that's a great idea!

Od peter Dne 2016-10-06 16:33

I tried it, it didn't work.
But I get a "Command successful (Code: 0)" after the command has run.

Od peter Dne 2016-10-06 20:15

Actually, this did work!
The files was deleted, but I still can't login with SSH

After deleting the broken files (size 0), you have to recreate them (ssh-keygen -A) and then to start the server (/etc/init.d/sshd start).

Certainly the most painful problem I got on my Omnia!

As an workaround you can disable sshd in startup and install and enable the dropbear ssh server.

Od peter Dne 2016-10-06 19:58

Would that make any difference to how the router runs?
Is sshd required by anything else on the router?

Od achim71000 Dne 2016-10-06 20:06

You can login via ssh/putty delete the keys /etc/ssh/ssh_host_* and then switch back to sshd.

Od peter Dne 2016-10-06 20:18

The files was actually deleted, but I still can't login with SSH if sshd is enabled
So back to my question:
Does everything run as they should with dropbear enabled instead of sshd?

Od achim71000 Dne 2016-10-06 20:35

Did you restart the sshd service or the router after you deleted the files? They are regenerated if they do not exist from the sshd start script. Can't tell you if there are packages installed whom rely on opensshd, just received the router and started inspecting. :wink:

Od peter Dne 2016-10-06 20:39

I have both the service and the router - Doesn't work
But with dropbear it works just fine

Oh, sure! Go play around with it! :grin:
