Is there some known bug with the TCP/IP implementation of telnet in the DEC
version of TCP/IP ? I installed a fairly recent version of TCP/IP on my 10
year old VAX and when I telnet to it the VAX is driven to its knees and the
hub goes wild. Doing a trace on the packets reveals zillions of

As you can see from the trace a couple of things are strange. Why are the
windows screwed up? Why are the TOS bits set? Very confusing.

Chuck,
Are you running TCPIP or UCX? Basically you should be running TCPIP V5.0A
(though I'm still on V5.0). With V5.0 on the VAX I've had no problem
whatsoever.
BTW, your best bet would be to post this question to comp.os.vms, and
include accurate version info, and hardware info.

Well, someone has not only reported it on comp.os.vms but figured out what
it is, the VMS telnet server in TCPIP 5.0A gets into an infinite loop
trying to negotiate ECHO which the client. It sends WILL_ECHO and the
client sends DONT_ECHO again and again and again. Sigh. This has cost me
enough time that I'm probably going to be demonstrating VMS system installs
at the VCF :-). I hope to have one MicroVAX II/GPX in a BA123, one VAX
4000/200 in a BA430, and one VAXServer 3400 (BA213) for sale. Should be
interesting...

OK, you win 1st Prize in the understatement catagory! You'd said a fairly
recent version of TCP/IP. Uh, V5.0A *IS* Current.

Is there a fix? I don't think there are any Patches for 5.0A available,
though I might be mistaken as I've not looked recently.

Suddenly I'm glad I'm not going to be there. I'd love a 4000/200 :^) Oh,
well. While everyone is having fun at VCF I'll be working a major upgrade
to my Hobbyist Cluster.

My exhibit is named "VAX House" and one the displays is going to be the
TinyCluster, three VLC's stacked with a monitor on top, a keyboard in
front, and a 4 port hub (3 ports + 1 uplink to the real world) It should be
a 4 port switch but that will have to come a bit later. Sort of "15 VUPS
the hard way :-)"

Yup, I scored the Dec 1999 ConDist on Ebay and that left we fairly up to
date. I did download the 7.2-1 patch from the ftp server though. :-)

Congrat's on the Dec '99 ConDist. I'm stuck at late '98, but can borrow
the
Dec '99 from my neighbor.

No, the TCPIP50A kit is on the 1999 ConDist.

Sorry, I am running VAX. Perhaps this doesn't bring VAX fully up to the
Alpha version of 7.2 but it fixed a couple of bugs I needed fixed (KFQSA
support for one)

Sounds like what you've really got is the patched version of 7.2, I thought
that was to good to be true. :^) Still the V5.0A info is good news, but
from the sounds of things I'm not sure I want to
try it. Actually I'm
wanting to test Multinet as it looks to have everything I
need that TCPIP
doesn't.
