Hello,
I just noticed that there are a huge number of packets flying back and
forth between a linux box and a vaxstations when I telnet to the vax. The
linux box is running a Redhat 6.1 install and the VaxStation is running
OpenVMS 7.2. The bandwidth usage seems to be around 50k/s of data flying
between the machines. The telnet session does work fine, but the vax
hardware is really old and when I tried to connect more clients it seems
to slow the machine down to a crawl. I dont' know if the problem is on
the linux end or the vax end. There is nothing going on in the telnet
session while this happens. It's just sitting idle. I have attached a
tcpdump (if you need something more, tell me) of the conversation.
192.168.2.12 is the VaxStation and 192.168.2.17 is the Linux machine.
