Question running ifup-local

[ilikefishdou]

I want to run a script with ifup to disable tcp offload since it's slowing down my DNS queries. I created an ifup-local script and put it in /sbin for ifup-post to call. You're supposed to turn off network manager in ifcfg to make it run. When I have NM_CONTROLLED=no, then I can't get anywhere on the network. ip addr shows the interface is up and it has an ip address (which it does because it's static), but if I try to ping something I get connect: Network Unreachable, but my script runs.

If I put NM_CONTROLLED=yes, then I have network access but my script doesn't run. Why is it doing that?

CentOS 7 minimal install.

Thanks!

Never mind. I figured I'd just use NetworkManager to run the script. I copied the ifup-local script to /etc/NetworkManager/dispatcher.d directory, renamed it, and then it worked at ifup time.

Still curious why turning off NetworkManager would keep my network from working, though.

Thanks!
