Linux or Linux virtual machine bridging mode uses PYTHON2 authentication drcom

Now many colleges and universities are using drcom client to manage the students ' Internet traffic and other information

Under Linux drcom client version Some schools may not be published

We can use Python to simulate landing drcom

The most important is the authentication server address

This need to grab packet analysis out of ip, self-google, it is easy to achieve

Run the py script under Linux (Python2 must be installed)

Command Line: python drclient.py

Attached below drclient.py
