How to persist ethtool settings through reboot on debian 8

Question

Hello how can i persist the following setting through reboot on a debian 8?

ethtool -K eth0 lro off
ethtool -K eth1 lro off

I already have try to add it under /etc/network/interfaces.d/ifcfg-bond0 with the following option:

ETHTOOL_OPTIONS='-K eth0 lro off'
ETHTOOL_OPTIONS='-K eth1 lro off'

But this doesn't work. Can somebody help me please?

Solution

Multiple possibilities come to mind:

• Put the lines into /etc/network/interfaces (or whatever file you're using underneath interfaces.d:

  iface eth0 inet static
      [...]
      post-up /sbin/ethtool -K eth0 lro off
      post-up /sbin/ethtool -K eth1 lro off
  

  (Actually maybe this is the most appropriate place, because it keeps network settings in one place.)

• Put the lines into /etc/rc.local, which is executed during startup, before exit 0 at the bottom:

   [...]
   /sbin/ethtool -K eth0 lro off && /sbin/ethtool -K eth1 lro off
   exit 0
  

• Put these lines into the crontab of a user which is able to run the commands, edit it via crontab -e:

   [...]
   @reboot /sbin/ethtool -K eth0 lro off && /sbin/ethtool -K eth1 lro off
   [...]

The first point have worked for me I only change /usr/sbin/ethtool to /sbin/ethtool. Thank you for the solution
