I have a wireless login script for attendees of OSDC who use Ubuntu, Debian, or anything else that can run scripts on connecting to a network and has essentially the same iwconfig output:
eth1 IEEE 802.11g ESSID:"Monash-Conference-Net" Mode:Managed Frequency:2.437 GHz Access Point: 00:13:7F:9D:36:C0
To save some tiny amount of time when connecting to the wireless, stick my osdc-login script in your /etc/network/if-up.d directory or equivalent and give it similar permissions to what’s already in there. You can get the latest version of the script at https://gitlab.com/puzzlement/osdc-2006-monash-wireless-login/raw/master/osdc-login, or through Bazaar git, with the repository at https://gitlab.com/puzzlement/osdc-2006-monash-wireless-login/tree/master. It’s very small, but feel free to send me improvements (although if using Bazaar git, please don’t check in a version containing the real username and password).
You need to replace INSERTCONFERENCELOGINHERE with the appropriate username and INSERTCONFERENCEPWHERE with the password. By running the script you will be agreeing to Monash’s terms of service, which are here.
