Automate the BITS Pilani Wi-Fi connection and login on Linux

Requirements

• Bash
• iproute2 and iw
• either wpa_supplicant or iwd
• (for auto-login) any one of NetworkManager, systemd-networkd, or ifupdown
• (optional) Netplan

Initial setup

Run any one of

su -c "bash <(wget -qO- https://github.com/sidstuff/bits/raw/master/wifi-setup.sh)" -

su -c "bash <(curl -fsSL https://github.com/sidstuff/bits/raw/master/wifi-setup.sh)" -

while connected to another network. If no root password is set but sudo is available, prefix the above command with sudo.

Note

If you have already setup Wi-Fi and only want to automate the login, replace wifi-setup.sh in the above command with login-setup.sh.

Login

Once the above script is done running, and you disconnect from the other network, you should be connected to the BITS-STUDENT Wi-Fi within a few seconds.

The captive portal login should happen automatically if you have NetworkManager, systemd-networkd, or ifupdown running, but if it doesn't, you can run

su -c "/etc/bits/login.sh" -

the file for which will have been created by the earlier command. The connection will also be kept alive by periodically fetching the keepalive page in the background when needed.
