(or atleast I have never been patient enough to wait it out, I give it about 30 s and give up) just installing both would be great for now if that worked. Although, I would like a scheme where it starts the right daemon because it could protentially less time and memory than starting both. Jens you are right about error trapping kernel message would be brain dead. However ifconfig STDOUT does give you how many packets are recieved, if you sent 1 and did not recieve any in reply the you have a smarter way of knowing whether or not you have a live line. You could use regex to parse that ifconfig STDOUT in the script. I am reaching here.:-) What do you think? Thanks, haggs

I don't it does not hang on my system, it does try to configure it's self, but does not hang. dhcpcd just sits there if it cannot find one. (or at least I have never been patient enough to wait it out, I give it about 30 s and give up) just installing both would be great for now if that worked. At least on my system it does work, kinda cludgy but it works. You can always take the card out.

A more elegant solution must be out there; I know that 95/98/NT have this problem also, so it's not easy. What do you think?

Re: laptop netconfig
I don't know if anyone's come up with a slick way to do this. I too would like to have such a thing at my disposal. You might be able to do something like this by just running dhcp and then checking to see if dhcp succeeded in getting an address and starting diald if it didn't.

I was thinking about using ifconfig in a script to temporarily configure the networks so that it might feel for a network pulse over the ether net. If no pulse is felt then it will start daild, otherwise it would start dhcpcd, then make a script called net-switch that would allow you to stop dhcpcd and start daild on the fly or vice-verse. The problem with accomplishing the net selection with DHCP is that the boot script will just hang if it can't find an address, and I have never been patient enough to wait for it to time out(if it does at all). I asked if anyone had done it because I did not want to go around re-inventing the wheel. Tell me what you all think. Regards, haggs
Re: laptop netconfig
Since the ethernet driver will detect carrier on the ethernet if you could detect the error correctly you'd be able to know if the ethernet was hooked up. Trying to send a packet is easy. Trapping the error correctly may be the hard part. If the kernel would log such a message then you could just monitor the log. This is a kind of braindead approach but may be the least intrusive and easiest. Justin Hagemeier wrote: Jens B. Jorgensen wrote: I don't know if anyone's come up with a slick way to do this.
