miss matching public keys methods

[wwencel]

When I'm trying to connect to netopeer2-server on the same system I'm getting:

> connect
nc ERROR: Starting the SSH session failed (Public key from server (rsa-sha2-512) doesn't match user preference (ssh-ed25519,ecdsa-sha2-nistp521,ecdsa-sha2-nistp384,ecdsa-sha2-nistp256,ssh-rsa,ssh-dss)).
cmd_connect: Connecting to the localhost:830 as user "wlodek" failed.

keys were added:

> auth keys add /home/wlodek/.ssh/wlodek_rsa.pub /home/wlodek/.ssh/wlodek_rsa

The new configuration was successfully applied.

No matter which connection type I set as preferred is it 'publickey' or 'interactive' at the first place I'm always getting the same error.

> auth pref
The SSH authentication method preferences:
	'publickey':   1
	'password':    2
	'interactive': 3

Where am I making mistake of miss matched rsa methods?

used versions:

• libyang-0.16-r3
• sysrepo-0.7.7
• libnetconf2-0.12-r1
• Netopeer2-0.7-r1
• libssh-0.8.6

Hi,
try it now, I attempted to add support for all known algorithms for libssh. Also, based on the error I believe this is a problem with the server host key, not your client key, so what you set up should be fine.
