Your syntax is wrong:

telnet localhost 210

Ignore iptables, you're likely to make things worse. If the process
isn't listening, no amount of messing with firewall rules is going to
make it show up. iptables --list will show you what rules actually

Also, iptables doesn't tell you about things that are listening anyway.
For that you want:

sudo netstat -lp --inet

This is your key thing that you need to be noticing. You don't have
permissions to bind on that port, you need root to bind to ports <1024,
so try for a different number and see if that works.
