 |
|
Hi,
I have the following problem: When I boot my Laptop, my Networkcard receives its IP address from the router. The Problem is, when I am not connected to my router it also tries to receive an IP address, that takes a long time.
My question is, if there's a way to either receive the IP manually or to set down the time the Laptop waits untill it tells me that dhcp failed.
Thanks,
Chris |

| Either remove net.eth0 from your default runlevel (rc-update del net.eth0 default) and start it manually when your connected (/etc/init.d/net.eth0 start). Or you can change the timeout for dhcpcd; in /etc/conf.d/net try adding dhcpcd_eth0="-t 5" |

or use ifplugd which starts net.ethX when a cable is plugged or an AP is found, and stops it when the cable is unplugged again.
Very handy for laptops. |

No didn't work. Here's my error log. It looks like ifplugd is started too late.
Nov 5 02:21:08 [dhcpcd] timed out waiting for a valid DHCP server response_

| Remove the net.ethX-script from your default runlevel. Ifplugd will start it if the networkcable is connected |

Yes thats right. Ifplugd totally takes over the contol of the net. init scripts, so they have to be removed.
I didnt think of mentioning that, because I thought I didnt need to, but I guess not all people examine what they use or install. I just assumed that. My bad. I apologize.
Here is what to do
Install the program (ok you already did that).
Edit /etc/conf.d/ifplugd
I have:
| Quote: |
INTERFACES="eth0 eth1"
ARGS="-f -u0 -d20 -b"
|
Remove all net.xxx scripts from runlevels that are listed in INTERFACES ie:
| Code: |
rc-update del net.eth0
rc-update del net.eth1
|
You may have to edit /etc/init.d/net.eth0 or /etc/init.d/net.lo because it makes wrong assumptions. See bug 34484. I dont know if the latest version of baselayout has this fixed.
Now edit /etc/sbin/ifplugd.action if fx. you want your pc to beep every time something is connected or reverse. (See emerge -s ^beep$) |
