Give a description > of the network traffic. 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. > Did you use any strange CFLAGS like -O3 or -f* > compile time options when you built the system?

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 :).
