debug1: connect address 196.24.44.62 port 22: connection refused
ssh: connect host sun.chpc.ac.za port 22: connection refused

either there not ssh server running @ address (not installed or not running) @ port 22. or there firewall blocking access port 22.

sure particular machine has ssh server running?
have been able log in other networks?
