Hi Guys,

This isn't strictly a Toolkit related question (although it'll help me run one 
more successfully!), so apologies for posting here.

Please can some help me with the following problem, preferably someone with 
RHEL knowledge:

To run a VenueServer/BridgeServer requires a full duplex/autonegotiation 'off' 
network configuration on the ethernet device. I enable this option temporarily 
via the following command:

ethtool -s eth0 autoneg off duplex full

To enable this option permanently, I can add the following line to the 
/etc/sysconfig/network-scripts/ifcfg-eth0 file:

ETHTOOL_OPTS="speed 10 duplex full autoneg off"

I've made this permanent change to a couple of Dell workstations (one is 
i686/FC6, the other x86_64/Centos5) running Toolkit VenueServer and it works 
fine.

However, when I do this on a Dell PowerEdge 1750 (RHEL3) the network device 
doesn't initialise on bootup. Having searched the boot.log files, it seems that 
kudzu stalls on bootup, and fails to initialise device eth0. As soon as I 
remove the above line from the ifcfg-eth0 file, kudzu is OK and the eth0 device 
initialises fine.

I don't have any spare RHEL machines to test this on, but can't imagine this 
would be an OS dependant configuration.

Regards, Ben.
