hoi,
firtst i need to say the situation that i'd like to debug is just a ad-hoc test solution. nothing critical...
but i ran into an unexpected problem i'd like to understand. and probably i'm overlooking something simple/basic.
i wanted to test the nat-setup at my current location and see if port-forwarding was working properly. so from machine A on the local network, i logged into a remote server using ssh, asuming that if port-forwarding on the local nat/router was working properly, i could from there login on machineB on the local network again.
the portforwarding is not at all a problem. network traffic shows there is a successfull connection between machineB and the remote server.
but the problem is that on the server ssh always fails with the 'Host key verification failed' -error.
usually all three machines have keys shared between them, and to i removed those, with no effect.
erased known-hosts, authorized_keys etc.. no effect
regenerated/re-distributed the keypairs, no effect..
the next step would be to generate new host-keys. but since that has a bit more impact (more/other people) i was wondering if it's really needed.
and above all, what is causing this failling verification?
thanks,
arri
