This is a lab in the Chemistry department; the box
in question is a dual-homed gateway to eight other
PCs in the lab. The box has a tight firewall, and
runs an apache server and an SSH server.
On the private network, the box also runs as a DHCP
server, Samba server and NTP server.
OS = 5-Stable.

The other PCs in the lab are two FreeBSD PCs and
various flavours of Windows.

No. My /etc/make.conf has:

CFLAGS= -O -pipe
NOPROFILE=true
NO_PF=true

I took this printout after I changed the value to 0.
Of course it is 1 when I test the polling, but when
I noticed that the ssh-tunnel connection problem
persisted, I changed it to 0; so that my ssh-tunnel
connection is not randomly closed :).

Thanks for your elaborate help!
