So, you’ve gotten your shiny new EVDO datacard working under Linux (if not, see High-speed cellular wireless modems (e.g. EVDO, HSPDA) in Ubuntu GNU/Linux 6.10) and you want to now setup the actual Internet connection?

In this article I document how I setup Sprint’s Mobile Broadband service with ppp in Ubuntu GNU/Linux 6.10.

Connecting to the Columbia Medical Center's Athens WiFi network with Linux

November 22, 2006 - 11:46pm — Samat Jain

Columbia University’s Medical Center, like many university campuses, has many WiFi access points. To meet HIPAA privacy regulations all their wireless networks require use of VPNs or sophisticated encryption protocols.

Connecting to their athens wireless network, which uses IEEE-802.1x authentication, is a little non-obvious with Linux, but is possible given your wireless card supports WPA and works with wpa_supplicant.

To save the many weeks I spent fiddling, the magic wpa_supplicant.conf stanza that works for me:

network={
  ssid="athens"
  key_mgmt=WPA-EAP
  eap=TTLS
  pairwise=TKIP
  group=TKIP
  phase2="auth=PAP"
  identity="foo"
  password="bar"
  priority=2
}
