Strace it. If you can't do that, run it like this:

telnetd -F | nc -nu <your_other_box's_ip> 12345

It will make telnetd send error messages to stdout
instead of syslog, and then nc will pipe them into network.

Use nc (or tcpdump) to see the telnetd's output
from the box as UDP packets arriving to your port 12345.
