Thanks for the response. I had suspicions that my switch may be the 
problem, tho it works fine on my desktop machine. The documentation in 
the kernel source tree said for bonding mode 5 I wouldn't need any 
special switch, however, in mode 5 I dont get any response.
Any idea of whether using two switches would make a difference, with one 
NIC per switch? Ill try that later when people are sleeping and wont be 
using any files.

thanks
Ross

| IPADDR=192.168.1.11
| NETMASK=255.255.255.0
| GATEWAY=192.168.1.1
|
| /etc/sysconfig/network-scripts/ifcfg-eth0
| DEVICE=eth0
| USERCTL=no
| ONBOOT=yes
| MASTER=bond0
| SLAVE=yes
| BOOTPROTO=none
|
| /etc/sysconfig/network-scripts/ifcfg-eth1
| DEVICE=eth1
| USERCTL=no
| ONBOOT=yes
| MASTER=bond0
| SLAVE=yes
| BOOTPROTO=none
|
|
| Hope this helps.
