How can I access by ssh to different to cisco hardware?

the error says:

SSH2 CLIENT 0: hostkey algo not supported: client ssh-rsa, server ssh-dss,ssh-dss               

actual ssh uses rsa key

The error mesage is telling you the remote host does not present an RSA key. Are you aaying it does?

It needs to have an RSA key if you want to ssh to it from a Cisco device.
