No, port 23 (Telnet port) on the core servers is a full feed port and
should only be used in this day and age by other servers who can only
connect to a Telnet port through their firewall (most clients and IGates
have no need for the full APRS-IS feed and it simply adds to the core
server bandwidth requirements).

Many firewalls block port 23 inbound and outbound if they block other
ports because Telnet is not secure and a potentially significant
security risk.  Because of perceived security risks by IT and because
the ports are full feeds, the need for port 23 on APRS-IS core servers
is somewhat out-dated.
