This script emulates HTTP client login for 24Online broadband billing gateway. You can download the script here scriptRoam.
The script uses curl and hence curl is required to be installed on your linux box. I have not tested the script on cygwin.
Prior using the script you need to change some parameters inside the script like the gateway address and username / password. Post that and assuming that u have ‘curl’ installed rename the script extension to .sh (dot sh) and chmod +x it to make it executabe.
