We're been having a problem using rlogin from our HP9000/350's
running HP/UX 6.5.

It seems that our net is losing the occasional packet here and there.
Shouldn't be any big deal since they get retransmitted, but the 
retransmission timeout is set unreasonably high -- somewhere on the
order of 2 seconds.

So I'll be typing along and suddenly the characters I'm typing stop
echoing to the screen.  I continue to type, and a couple of seconds
later there's a quick burst of activity and the echoing catches up
to where it should be.  Everything works fine for another minute or
so (depending on the load on the net), and then it happens again.  
Annoying.

So, is there any way to correct this?  Some parameter I can set
somewhere?  Isn't the timeout supposed to be set using an adaptive 
algorithm?  The normal roundtrip time for a packet is on the order 
of milliseconds.

tnx,
Scott
