Trouble Making SoftAP Script Work
First off i want to say i did not make this script, i did find it off this forum. Second, I'm having trouble having clients connect. Clients take forever to connect, and when they do they are not getting Ip addresses.
Any help is much appreciated.
Backtrack 2.6.28.1
Orinoco Gold b/g using ath5k drivers
Latest Aircrack-ng
planning on updating 2.6.28.3 (due to updated ath5k mesh driver fix)
Code:
#!/bin/bash
modprobe tun
airmon-ng stop mon0
airmon-ng start wlan0
# -=SoftAP Options=-
xterm -e airbase-ng -P -C 5 -c 6 -e Linksys -a 00:14:6C:F0:AD:00 wlan0 &
ifconfig at0 up

ifconfig at0 192.168.1.129 netmask 255.255.255.128

Are you writing the variables for the dhcpd.conf file yourself? What is in your dhcpd.conf file?
I ask this because in the script you posted, all the parameters for the dhcpcd.conf file are commented out, so it appears that the script is not writing anything to it.
sorry about that

Sorry, I've never used SoftAP, that dhcp comment thing was my one shot! Your cat line and EOF line need to be uncommented also.
Good Luck...
lol, thanks. Im thinking im gonna try it with the madwifi drivers, right now im using the ath5k and i think that might be the cause...Originally Posted by cybrsnpr
but still unsure
sorry for bumping a old thread but im having DNS issues and im hoping somone can help.
im using the below code with a linksys wusb54g wificard (rt2570 chipset) and the code works fine my psp gets a IP and the AP shows up but when i try to goto google all i get is
in tshark, im no linux guru but it looks to me like the SoftAP isnt connecting to OpenDNS and OpenDNS isnt responding back. any help?Code:0.000000 192.168.1.140 -> 208.67.222.222 DNS Standard query A google.com

ive got backtrack3 running in vmware on my main comp. eth0 of the backtrack is assigned a ip (192.168.2.7) and is connected to the internet my router is using OpenDNS and is a DHCP server and uses a static ip.
if you need anymore info just let me know

shouldnt that line be saying forward to eth0 or 192.168.1.1 or whatever your router is? and then let the router send out the request
thanks its working now
amazing how something so simple can ruin your day.
