to the end of being pedantic, i've documented everything i did to get this to work:
DISCLAIMER: this documentation is by no means an attempt to bolster my ego, but rather an attempt to thoroughly document a procedure i could not find easily in the online "literature"
1) read what
has to say about setting up DHCP servers and clients.
2) run dhcpd -d -f $W_IFACE on your access point, w/ $W_IFACE=your AP wireless interface; then run dhcpcd -d -B $R_IFACE on your remote computer, w/ $R_IFACE=your remote wireless interface
3) ping to check the connection once a successful DHCPOFFER is received. this looks like:
DHCPDISCOVER from 00:09:5b:78:59:8a via wlan0
DHCPOFFER on 192.168.1.200 to 00:09:5b:78:59:8a via wlan0
DHCPREQUEST for 192.168.1.200 (192.168.1.1) from 00:09:5b:78:59:8a via wlan0
DHCPACK on 192.168.1.200 to 00:09:5b:78:59:8a via wlan0
!! (this MAC has been changed to protect the innocent) !!
NOTE: if you get any messages like "send_packet: Operation not permitted," you should probably disable or modify your firewall while configuring the wireless network. this will allow the packets through.
this is where i'm currently at, and i'll post more about fixing iptables to work with the wireless, encryption, etc. as it comes up.
i do have just one question (i'll probably just answer it myself): how do i route from the AP wireless interface to get internet access through my other ethernet card? does this involve "bridging"?
