dhcp to background

Hi folx,

how can I achieve to start dhcp (/etc/init.d/net.eth0) in background so that the system doesn't hang some minutes when booting without a network connection?

take care

I recommend looking at the ifplugd app.

If your machine regularly starts without a network cable, this program will deal with it nicely.

I don't know how to do exactly what you are asking, but I have a couple of options.

Lower the timeout in /etc/conf.d/net:

Code: Select all

dhcpcd_eth0="-t 10"

This sets the timeout to 10 seconds.

EDIT: hmm....I wonder if you can put a & at the end of those options to put it in the background.

I've also found that you can ^C and interrupt the dhcp.

Good luck!

To use ifplugd, you remove the net.eth0 script from your default runlevel

Code: Select all

rc-update del net.eth0 default

And then you install ifplugd

emerge ifplugd

rc-update add ifplugd default

With baselayout-1.12 net.eth0 will launch ifplugd automatically if installed

So the reverse of what you said is true ....

Hey guys.

Hope you don't mind me butting in but is ifplugd ment to run dhcpcd automatically when it detects a network conection and brings up eth0?

I installed ifplud and it controls my eth0 fine (does the backgrounding at boot and brings the interface up) but it wont run dhcpcd.

Any help?

I'm having the same problem. When ifplugd starts at boot it detects the network connection and brings up eth0, when I do ifconfig it even gives an IP address but it is useless to connect.

I had to manually do this to get a working IP address:

Code: Select all

rm /var/run/dhcpcd-eth0.pid
ifconfig eth0 down
ifconfig eth0 up
dhcpcd eth0

The IP Address is exactly the same but it works now.

I hated doing this so I modified the /etc/ifplugd/ifplugd.actions file by adding:

Code: Select all

dhcpd eth0

Now I just have to make sure that I connect the Cable after it boot up, or disconnect and connect it back. Why is this happening?

I have the same problem. Where exactly do you add this "dhcpcd eth0" to the /etc/ifplugd/ifplugd.actions file?
