I cannot ssh to SL6 machines from current MacOS or Debian 20 or 22:

root@daq00:~# ssh ladd00
Unable to negotiate with 142.90.111.60 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss

Are there updated ssh rpm packages anywhere?

In the mean time, this workaround works for me:

bash-3.2$ ssh -oHostKeyAlgorithms=+ssh-rsa -oPubKeyAcceptedAlgorithms=+ssh-rsa ladd00
