Description Pierre Ossman cendio 2013-03-28 12:29:38 CET
Currently we only fetch the RSA and DSA host keys from the agent's ssh server. There are however other standards, most prominently ECDSA, that also are available.

Most distributions have this turned off because of patent concerns, but Ubuntu ships with it enabled.

This causes problems for our client as ssh will pick the "best" key, which might not be one of those we got from vsmmaster. This presents an ugly warning in older clients, and can completely refuse the connection in current trunk (see bug 2945).

Preferably we should fix this so all possible key types are supported, and not just add ECDSA to the list.

Fixed in r27693 and r27694. Also removed sshlib in r27695 as this was the last user.
Comment 2 Henrik Andersson cendio 2013-10-22 14:08:07 CEST
Verified using ThinLinc client build 4122 against Ubuntu 12.04 configured
to only use ECDSA hostkey which worked as expected.

Tested using 4.0 client failed, with "Processing SSH output: no hostkey alg"
