Hi * I have the same problem in some networks, installations in many other schools work fine. tcpdump or ethereal show a lot of UDP fragments when this happens. Once I also had this problem with a rtl8139 card: At the same switch, next to the server , the workstation woked fine, but at the other side of the building, packages go (or don't go) thru several switches & network-speeds : 100baseT--fiber-optic--100baseT the same machine did not work anymore. I did google and read about this issue today and what I'd like 2 try one day is to change the mount options on the client side. But to try this, I have to build a new kernel+initrd image :-( I'd like to try the following options: rsize=1024, wsize=1024 ... to avoid fragmentation tcp ... to try NFS over TCP instead of UDP another tunig option I found is to increase the Socket Input Queue: (which might crash the machine after a while - you are warned) echo 262144 > /proc/sys/net/core/rmem_default echo 262144 > /proc/sys/net/core/rmem_max (see: http://nfs.sourceforge.net/nfs-howto/performance.html ) Anselm: where do you buy rtl8139 for less than 4 EUR ?
