hi, i'm not able to connect to my new hardened gentoo server using x2go.
No matter which key type i select for the connection, the client (v. 4.0.5.0) terminates with the following:
kex error : no match for method server host key algo: server [ssh-rsa,ssh-ed25519], client [ecdsa-sha2-nistp256]
I have rsa and ed25519 keys on my client and server.
sshing from the shell works like always. log is attached.
do you have an idea, whats might wrong?
thx, k4t
