In order to access the internet from the IIT Bombay network, open https://internet.iitb.ac.in on your browser and login with your IITB LDAP login and password.
Sometimes you may not be able to open a GUI browser such as firefox or chrome, because you’ve logged in to a lab machine (such as sl2-11.cse.iitb.ac.in) via ssh.
In these cases, do one of the following:
Either, use the command-line browser lynx or links.
In lynx, press g and enter internet.iitb.ac.in. You can navigate the page using arrow keys.
Enter your username and password and submit, like you’ll do on a GUI-based browser.
Or, use the following python3 script:
#!/usr/bin/python3
import requests
import getpass
import sys
ph='10.201.250.201'
ph='internet.iitb.ac.in'
if (len(sys.argv) == 2) and 'logout' == sys.argv[1]:
r = requests.get('https://'+ ph)
s = r.content.split('checked="checked"')
t = s[0].rsplit('value=', 1)
ip = t[1].strip(' "')
payload = {'ip':ip, 'button':'Logout'}
r1 = requests.post('https://' + ph + '/logout.php',
cookies=r.cookies, data=payload)
else:
r = requests.get('https://' + ph + '/index.php')
payload = {'uname':input('IITB LDAP Username: '),
'passwd':getpass.getpass()}
r1 = requests.post('https://' + ph + '/index.php',
cookies=r.cookies, data=payload)
It will ask you for your IITB LDAP username and password and login.
There is also a python package called iitb-login: https://pypi.org/project/iitb-login/.
It saves your password in your home folder (in an encrypted file) the first time you enter it.
Please follow the instructions on the above page to use it.
