i set up a fileserver using nfs (only linux clients) which is
connected to a hub. all clients are also connected to this hub, it is
some 3com officehub afair (10/100). the server and the clients all
have rtl and tulip chips and i had no problems configuring them
(everything runs at 100 MBit).
when i transfer large amounts of data i can see the hub's collision
led be lit almost all of the time...this isnt normal is it?
also check out the collisions field in ifconfgs output:
eth0 Link encap:Ethernet HWaddr 00:50:FC:56:8D:06
inet addr:192.168.0.3 Bcast:192.168.0.255
inet6 addr: fe80::250:fcff:fe56:8d06/10 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:4137227031 (3.8 GiB) TX bytes:2308886771 (2.1 GiB)
the funny thing is that i get quite good transfer rates despite the
large amount of collisions. copying large files i get like 77 MBits/s
peaks and 50 MBits average (measured with nload).
where shall i start tracing the problem?
i am using debian sid (yes sid and this is not the prob since it was
the same using woody :)) nfs-kernel-server and nfs-common version
1.0.2-1. on the server i use kernel 2.4.18 with the sgi xfs patch and
the clients use 2.4.19 with the xfs patch.
any help would be appreciated
