Geo:    There's something wrong with the ICMP handling in a router between
you and me.  On both Windows and Linux, both sides request a Maximum
Segment Size (MSS) upon connect.   In the middle of a stream, it suddenly
reverts to minumum MTU (68 bytes), sending one character per packet.  There
are no ICMP messages from the Linux box, so it must be in the MTU / PMTU
sequence.

    Is there a firewall, or is news.barkto.com naked on the internet?

    I can't ping news.barkto.com from here, or I could try a manual MTU
discovery to see what gives.

  [Randall, I'm on DSL - are you on DSL also?   The ATM packet size could
have an effect on our problem]
