No solutions, but the general comment that I've experienced this problem 
regularly over the last 2 1/2 years of using linux.  Sometimes it doesn't 
like a particular machine, sometimes a particular OS, sometimes the 
status changes over the course of time.  Telnets to or from Telebit 
routers were always dicey.  Sometimes 5 or 6 successive attempts would 
result in it working.  Sometimes opening a FTP connection to the same 
host appeared to change something so that the telnet would work.  Last 
week, I was telnetting from london to boston from a Win95 client 
(Ughh!).  It worked fine for two days, then suddenly stopped, and I then 
would telnet to a sun in boston, and then to the linux box (1.1.59).  It 
worked fine.  I've seen the same problem in .99 kernels, 1.[0-3][0-9] 
kernels.  I suspect it's some kind of timing subtlety in TCP, but I've 
never had the time to set up a comprehensive test bed.
