I'm sorry, but I'm probably not very helpful with that. I just installed
an ftp server to copy the file which went flawless at work. My setup at
home involves an outdated installation, so it isn't suitable for bug
Have you tried directly connecting together the two machines that are
No, the x-wires I have are too short for that, and it would have made
the mailserver unreachable for the users.
Have you done tcpdumps on the links that the machines exist on?
Once I tried out tcpdump, and it yields lots of data with which I can do

None that I know of. There have been some complaints about slow network
speed during the transition from the old 10Mbit switches to the new
ones, and my idea was that having 10Mbit switches and a significant
amount of 10Mbit clients on the network, together with 100 and 1000Mbit
stuff, is a combination that may introduce problems with network speeds.
After the transition was completed, there were no more complaints.
Overall network speed is fine now :)
What network cards do you have in the machines that you are dealing
Ethernet controller: Broadcom Corporation NetXtreme BCM5702X Gigabit
Ethernet (rev 02)
nVidia Corporation CK804 Ethernet Controller (rev a3)
At home, it's a 3Com 3c509 and another NVIDIA, probably the same type.
But IIRC, I tried it on two of the 3Coms and only later switched to the
onboard card. I tried to copy over a number of files, about 550M in
total, and the server I copy to freezes during copying.
Thus, I just consider NFS as deprecated.
