Description Adam Stylinski 2017-12-07 00:00:36 UTC
For some reason in 4.1.1.0 I get back an error dialog from a messaging seemingly from libssh complaining about not being able to use the aes256-gcm cipher (I can ssh with vanilla ssh to the server just fine).  This cipher is not blacklisted and I can connect to clients with this cipher just fine.

Here's some output from ssh with -vv, where it shows the key exchange works just fine:

debug1: kex: algorithm: curve25519-sha256
debug1: kex: host key algorithm: ecdsa-sha2-nistp256
debug1: kex: server->client cipher: aes256-gcm@openssh.com MAC: <implicit> compression: none
debug1: kex: client->server cipher: aes256-gcm@openssh.com MAC: <implicit> compression: none

(I get prompted for a password and can log in).

It's definitely something fishy with x2goclient.

Perhaps this was user error, I'm not sure, but I can't reproduce this issue,  anymore.
