I'm running ISC Unix 2.2 (SVR3.2) with TCP and X11R5.  I'm
testing some software on another machine which establishes
TCP connections to my machine, but occasionally drops the 
connection without telling my machine.  If I do 'netstat' I get:

% netstat

Does anyone know how to remove connections from this list?
I want to remove the ones with dvx.cam.nist.gov.  They don't 
seem to time out.  They don't seem to go away if I kill
X-Windows.  I tried bringing down the Ethernet port with
'ifconfig wd0 inet down', but that doesn't seem to remove
them either.  I'd appreciate any pointers.
