I've got a better one...
Using Novell Lan WorkGroup v5.0 as the telnet client;
I achieve connection, but during the telnet negotiation process the
telnetd dies with a Segmentation Fault (signal 11). With the -D report
on I get the following on the client:
td: send do TERMINAL TYPE
td: send do TSPEED
td: send do XDISPLOC
td: send do NEW-ENVIRON
td: ttloop
td: netflush 118 chars
td: ttloop read 3 chars
td: recv do ECHO
td: send will ECHO
td: ttloop
td: netflush 78 chars
td: ttloop read 3 chars
td: recv will TERMINAL TYPE
td: ttloop
td: netflush 66 chars
td: ttloop read 3 chars
td: recv wont TSPEED
td: ttloop
td: netflush 59 chars
td: ttloop read 3 chars
td: recv wont XDISPLOC
td: ttloop
td: netflush 61 chars
td: ttloop read 3 chars
td: recv wont NEW-ENVIRON
td: ttloop
td: netflush 70 chars
td: ttloop read 3 chars
td: recv do ECHO
td: ttloop
td: netflush 55 chars
td: ttloop read 15 chars
td: netflush 26 chars
Gdb on the resultant core gives:

I am persuing this as I can, once I get the source for telnetd.
I will post progress as I can acheive it.
