csc-wireless no longer exists. Members are advised to use eduroam or uw-unsecured.


Rosetta Stone

See IST's page http://ist.uwaterloo.ca/cs/wireless.html for Windows and other devices.

The ca_cert line is only needed to verify the authenticity of the eduroam AP, and is otherwise not actually needed to connect to it. Keep in mind that removing it from your config means that you are technically vulnerable to someone creating a fake eduroam access point and using it to grab your Quest login, though honestly the chances of this ever happening on campus are extremely unlikely.

Linux

If you don't wish to have your password floating around in a text file in /etc, then (at least for the wpa_supplicant based network managers) you may take the output of

echo -n "hunter2" | iconv -t utf16le | openssl md4

and replace the password line with

password=hash:HASH_HERE

netcfg

Toss this into /etc/network.d/, making sure you edit identity and password. sudo netcfg eduroam

CONNECTION='wireless'
INTERFACE=wlan0
SECURITY='wpa-configsection'
IP='dhcp'
CONFIGSECTION='
    ssid="eduroam"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    group=CCMP
    eap=PEAP
    identity="userid@uwaterloo.ca"
    password="hunter2"
    ca_cert="/usr/share/ca-certificates/mozilla/GlobalSign_Root_CA.crt"
    phase2="auth=MSCHAPV2"'


netctl

Toss this into /etc/netctl/, making sure you edit identity and password. Replace wlan0 with the correct interface. Your correct interface can probably be seen in the output of

ip link

and probably is the one that starts with 'w'.

To connect, run sudo netctl start eduroam

Connection='wireless'
Interface=wlan0
Security='wpa-configsection'
IP='dhcp'
WPAConfigSection=(
    'identity="userid@uwaterloo.ca"'
    'password="hunter2"'
    'ssid="eduroam"'
    'key_mgmt=WPA-EAP'
    'eap=PEAP'
    'ca_cert="/usr/share/ca-certificates/mozilla/GlobalSign_Root_CA.crt"'
)


wicd

Toss this into /etc/wicd/encryption/templates/ and edit /etc/wicd/encryption/templates/active to include a line with eduroam.

name = Eduroam UW
author = Steven She
version = 1
require username *Username password *Password
-----
ctrl_interface=/var/run/wpa_supplicant
network={
    ssid="$_ESSID"
    scan_ssid="$_SCAN"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    group=CCMP
    eap=PEAP
    identity="$_USERNAME"
    password="$_PASSWORD"
    ca_cert="/usr/share/ca-certificates/mozilla/GlobalSign_Root_CA.crt"
    phase2="auth=MSCHAPV2"
}

wpa_supplicant

network={
    ssid="eduroam"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    group=CCMP
    eap=PEAP                                      
    identity="userid@uwaterloo.ca"
    password="hunter2"
    ca_cert="/usr/share/ca-certificates/mozilla/GlobalSign_Root_CA.crt"
    phase2="auth=MSCHAPV2"
}


The previous setup has been archived for posterity.
