The "sh -c" doesn't look right in that command. It should just echo the device id to the bind file. However, it's generally recommended just to use the devbind script, as more writes to sysfs may be necessary first, e.g. to register the device ids first. > I have required permission for the file. > I tried doing with "sudo" > I dont have selinux running > So not sure whats blocking me.

For example, what NIC card is this? Are there any useful error messages in dmesg? /Bruce
