Hi,

some days ago I upgraded the kernel to 2.6.11
Since this upgrade the speed of the network is not so good ... (I would say very bad).
The connection is 100Mb full duplex (or at least should be), but the speed of an ftp transfer with a computer 10 meter away is about 25 Kb/s. Before the upgrade (maybe I should call it downgrade) it was around 2 Mb/s. I'm sure that nothing else has been changed.
Can you help me finding the mistake I did ?
What informations can I give you to help me ?
The only change I remember is the I exchanged the name of the 2 network cards I had; before the name was eth0 for the "external card" (the one I use to connect to other computers) and eth1 was used to connect my notebook to the workstation; Now they are in the other way. Could the problem be related to this ?
thank you,
marco

the external network card is controlled by e100 (as before).

well you need to start by looking for the usual suspects really... is there anything blatant in "dmesg" or /var/log/messages ? what about the information provided about the card by either ethtool or mii-tool?

Thank you !
so the only strange message of dmesg is

nfs warning: mount version older than kernel [written one time every 2/3 minutes]

mii-tool gives
SIOCGMIIPHY on 'eth0' failed: Operation not supported
SIOCGMIIPHY on 'eth1' failed: Operation not supported
no MII interfaces found

ethtool gives ("ethtool eth1")
Settings for eth1:

So eth1 is half duplex; How can I change it ? [before I used a line in the modules.conf, but now it's not used ...]
Thank you very much again !
marco

sorry !
I forgot to say that the driver is compiled not as module.
marco

ok !
using the command:
ethtool -s eth1 autoneg off duplex full
I managed to set full duplex operation and now the speed is the right one.
I couldn't image such a big difference ... sorry for my ignorance ...
maybe you can suggest me something to read ...
2 last questions,
1. how can I set [during the boot] the speed ?
2. Why that message on the NFS [I compiled the kernel with the nfs 3 and 4]
thank you again,
marco

you'd force the speed by setting a line that apparently would read "option e100 e100_speed_duplex=4" in /etc/modules.conf

nfs.. no idea actually... seen it around, but i don't know.

The files modules.conf is used by the kernel 2.6 ?

However I managed to change the setting adding the line :
ETHTOOL_OPTS="speed 100 duplex full autoneg off"
in the file
/etc/sysconfig/network/ifcfg-eth1
(I have the suse 8.2)
Thank you
