how to check ssh encryption strenght

Hi

I was just wondering how to tell how strong the encryption is on a existing ssh connection. I just upgraded the host keys to more bits on a server and now want to see if it is really taking the new strenght.

cheers

Hi,

I don't think that you can get this info for a currently running connection. I think that you will need to stop the session, stop the sshd (server) and then restart the server with the debug option '-d' you can get more detail by adding a second or third '-d'. It runs sshd in the foreground and will only handle one connection. Have a look at the man page for sshd.

Hope this does the trick.

Sorry for the late reply.
I will try that, although it will probably make me end up hook up a monitor to that machine again since I will succeed in kicking myself off the network access ;-)

Thanks anyway,

Markus
