 Posted: Thu Feb 10, 2005 6:26 pm Post subject: Newbie question: Need based dhclient configuration? [SOLVED] |
 |
|
Hi all,
as indicated in the title, this may be a dumb question, but I can't seem to find an answer anywhere. I run the latest gentoo on my stationary system and my laptop. I use dhcp to connect to the internet, which works excellently for my stationary can. However, my laptop isn't always connected to the LAN via the ethernet card, and when it isn't, I find it is a bit of a pain to
a) wait for the dhclient script to exit on bootup, and
b) manually restart eth0 if I hook up without rebooting.
My real problem is laziness, of course.  So, is there a way to get the dhclient to run on a "need basis"? That is, it starts on bootup if I am connected, and when I do connect otherwise?

| Code: | | rc-update del net.eth0 default |
that will stop eth0 from coming up at startup, that's what I have on my laptop as well because I use a combination of eth0 and wlan0.
edit: i think control + c will stop it from searching for a DHCP server too on boot. maybe i'm wrong though. |

Well, that much I know. It still means I have to manually initiate the script when I connect, which is part of what I'm trying to avoid. Ctrl+C does not abort dhclient, as far as I know... |

| I'm in the same boat as ErikM, Is there some way to make the dhcp scripts background after 2 seconds? I noticed that on a suse 9 install at my work it's dhcp script backgrounds after so many seconds, but i have not had the time to view the script is there some way to do somthing similar on gentoo, i viewed the script on my gentoo install and it seems to already run in the background...? |

Thanks a bunch!!! This is exactly what I wanted!! 
For others having the same "problem", do
patch /etc/init.d/net.eth0 according to here, set
in /etc/conf.d/ifplugd (the other default settings work fine), then do
| Code: | rc-update del net.eth0 default
rc-update add ifplugd boot
/etc/init.d/net.eth0 stop
/etc/init.d/ifplugd start |
and, th-th-th-thats all folks!
(Disclaimer: I don't know whether ifplugd is best set as a boot service or not, feel free to correct me on this...) |
