Hi Ben, Thanks for replying. I tried % /sbin/modinfo /lib/modules/`uname -r`/kernel/net/bridge/bridge.ko and obtained the following
openflow@openflow:~/openvswitch-1.1.0pre2$ /sbin/modinfo /lib/modules/2.6.32-28-generic/kernel/net/bridge/bridge.ko filename: /lib/modules/2.6.32-28-generic/kernel/net/bridge/bridge.ko version: 2.3 license: GPL srcversion: 7F81763D8FF0740B7DEF245 depends: stp vermagic: 2.6.32-28-generic SMP mod_unload modversions 586 But, I could not find openvswitch_mod.ko under /sbin/modinfo. Could you please assist ?
