 Posted: Fri Apr 13, 2012 10:14 pm Post subject: [SOLVED] How to make changes via ethtool persistent |
 |
|
I have made some changes on my NIC using ethtool and found out they are nor persistent. After each reboot, I have to issue the same ethtool command manually. While searching the forums, I found this topic
https://forums.gentoo.org/viewtopic-t-482890-view-previous.html?sid=e9aec1dda5d94a817015e87085f0f7e6
it suggests modifying /conf/init.d/net.ethX file as
| Code: | | local unset_functions=false |
However, I couldn't find any such line in /conf/init.d/net.eth0. II tried adding that line at the very end of the file, and it didn't work.
Is there a workaround to make changes to the NIC via ethtool persistent?
Thanks.

zirtik,
Make a file in /etc/local.d/ called, say, ethtool.start
In this file put the commands as you would type them at the keyboard.
Be sure to read the README file there.
Your /etc/conf.d/net file supports pre and post up functions and pre and post down funtions.
postup sounds promising, Read /usr/share/doc/openrc... to see how to use those functions.

zirtik,
Take a look at /usr/share/doc/openrc-0.9.9.3/net.example.bz2 postup() function as NeddySeagoon mentioned. I use the preup() function to manipulate the wired and wireless interfaces.
| Code: | postup() {
local unset_functions=false
return 0
}
|
should do it  |

Thank you. I created ethtool.start and added all ethtool commands as you suggested, made the file executable and rebooted. It worked!

Did you suggest this as an alternative solution to what NeddySeagoon said? Should I still modify the postup() function or leave it as is? It seems to work now, without postup() being modified. |

zirtik,
I suggested both - both work.
Gentoo is about choice - its over to you.

zirtik,
If you scripted in /etc/local.d/ then that's all you need 
| Quote: | | It seems to work now |
and there's no substitute for something that works
