The syntax for accessing a port directly using tcp port# is::
ssh –l sx_user –p tcp_port_N sx_ip_addr sx_user@sx_ip_addr's
password: <prompted by ssh>
telnet –l sx_user sx_ip_addr tcp_port_N Password: <prompted by
telnet>
The syntax for accessing a port directly using the ip address assigned per port is:
ssh –l sx_user dpa_ip_addr sx_user@dpa_ip_addr's password:
<prompted by ssh>
