CHAPTER 11. USE 11.4. ERRORS YOU COULD ENCOUNTER

#/etc/wp_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0

eapol_version=1

ap_scan=1

fast_reauth=1

network={

ssid="(your SSID)"

proto=WPA

pairwise=TKIP

psk= (quoted text or hexadecimal number)

priority=1

}

(You may have a look at

http://linux.die.net/man/5/wpa_supplicant.conf

.) You also need to

install the package wpa_supplicant.

11.3.4.5 Drivers

There are roughly two different drivers:

1. hostap: supports WEP and WPA,

2. acx: supports WEP.

11.3.5 Firewall

Just like in every normal Linux distro, you may use the following trivial ﬁrewall:

iptables -P OUTPUT ACCEPT

iptables -P INPUT DROP

iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

To make this happen on boot-up, you may create a script with these lines, put it into

/etc/init.d/firewall, and make soft links to the script from the rc3.d and rc5.d directories.

11.4 Errors You Could Encounter

It is possible that you encounter different errors, such as, in the console:

xxx: command not found.

In this case, please check that

/sbin/

is in the environment variables. If it is not the case, simply

add it, or always use /sbin/ before each app, i.e.

/sbin/modprobe mymodule

/sbin/ifconfig myadapter

If you do not want to do this every time you want to use such a command, you may simply add

sbin to $PATH(it is actually only necessary if you are using a liveram disk):

PATH=$PATH:/sbin

export PATH
