dhclient not working

Mr_C · 12-23-2005, 04:55 PM

Hi all, I have a installed the madwifi-ng drivers for my netgear wg511t card. I've set it up in ad-hoc mode and I connects to another windows pc (which has ICS enabled). The windows icons says I have connected; signal strength excellent...
The problem is that the command "dhclient ath0" returns the following:

Code:

Help as to why the dhcp client is not functioning.

Two things...First, have a look at the output of iwconfig to make sure that the card is ther. Second, if this is a stock Slackware box, usd dhcpcd instead of dhclient.

Ok I did use dhcpcd as well and was in fact issued an ip address. I thought it was dhclient not working. But thats not the problem. I could not ping the other pc. So I reverted to static ips
PC(ICS)1.1.1.1-->slackbox1.1.1.117

Like I said the icons indicate excellenct connectivity but I can't ping whatsoever. Don't understand why.

you need to set the default gw. (if the windows box is going to share the connection, then it will be the default gw) man route. (i am a bit confused as to why you try to use dhclient for an ad-hoc connection..)

Mr_C · 12-24-2005, 11:59 PM

You need dhcp for ICS
Actually the problem was two fold:
1-Windows was messed up: I had to download this winsockfix app to reset all winxp network settings
2-The madwifi driver as of 22/12/2005 is broken for ad-hoc.
Have to wait till that gets resolved.

hrm, i seem to remember running nat on my box without dhcp..
