Hi,
I think I have found a bug that has been in the NetBSD-current
TCP protocol engine. Try the following :
1. telnet into a NetBSD-current machine {My configuration is below}
2. Execute the following script.
# while [ true ]
> do
> cat /etc/termcap {or any text file}
> done
You will notice that the output will stop after a short while and will
not continue. When doing a netstat via another session I notice
that the sending side is stuck with about 5700 characters in the
send queue. After several minute the telnet connection breaks from
the client side. Caveat: I have not put a Lan Detector on this
to really know the sequence of events. I will if the developer of
the TCP protocol engine contacts me.
I have tried this on three types of i386 boxes.
1. 486/66 DX2 32MB memory NE2000 (real)
2. 386/33 8MB memory NE2000 (real)
3. 486/33 8MB memory NE2000 (real)
Any help would be appreciated since the machines are being used
to service and Internet POP.
PS> I tried this same test with FreeBSD 1.0 and it didn't lock the
session.
PSS> I tried this test from a FreeBSD box, SUNOS 4.1.3, and NetBSD.
I got the same results every time.
