4 Network Services and Tools Provided by OnRISC

4. Network Services and Tools Provided by OnRISC

The OnRISC can be accessed via Ethernet for remote usage and ﬁle sharing. For this purpose there

are several services such as telnet, ssh and ftp installed and preconﬁgured. For WLAN conﬁguration

wpa_supplicant and wireless-tools are included in the distribution.

4.1. WLAN Conﬁguration

Wpa_supplicant

is a WPA Supplicant for Linux, BSD, Mac OS X, and Windows with support for

WEP, WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component

that is used in the client stations. It implements key negotiation with a WPA Authenticator and

it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

4.1.1. Managed Wireless Network (Wpa_supplicant)

Wpa_supplicant uses /etc/wpa_supplicant.conf ﬁle for its conﬁguration (see the Listing be-

low).

ap_scan=1

# no e n cr y pti o n

s s i d ="TEST"

key_mgmt=NONE

}

# WEP enc r ypt i on

network={

wep_key0=xxxxxxxxxxxxxxxxxxxxx

wep_tx_keyidx=0

s s i d ="TESTWPA2"

pr ot o=WPA RSN

key_mgmt=WPA−PSK

p a i r w i s e=CCMP TKIP

psk="xxxxxxxxxxxxxx "

}

Listing 2: /etc/wpa_supplicant.conf

WLAN interface is automatically conﬁgured on system’s startup (see Section 2.3). To test the

conﬁguration just run:

/etc/init.d/networking restart

Wpa_supplicant can also be called manually to investigate conﬁguration problems:
