NCSA telnet doesn't work with path MTU discovery enabled. This is due to abug in NCSA that also stops it working with other modern networking codesuch as Solaris.The following information is courtesy of Marek <marekm@i17linuxb.ists.pwr.wroc.pl>There is a fixed version somewhere on ftp.upe.ac.za (sorry, I don'tremember the exact pathname, and this site is very slow from here).It may or may not be faster for you to get it fromftp://ftp.ists.pwr.wroc.pl/pub/msdos/telnet/ncsa_upe/tel23074.zip(source is in v230704s.zip).  I have tested it with 1.3.79 (withpath mtu discovery enabled - ncsa 2.3.08 didn't work) and it seemsto work.  I don't know if anyone is working on this code - thisversion is over a year old.  Too bad - it's faster and often morestable than these windoze telnets, and runs on almost anything...
