Run the following command:

sudo pip install scapy netifaces commands pycurl

It works basically on the concept that cyberoam limits bandwidth per-ip basis. Hence, the more ips you have, the more bandwidth you have. This download manager basically searches for free ips in the subnet and automatically assigns them for your computer as per you requirements.

Run the PyDloader.py file as sudo user:

PyDloader.py <url> <filename> <numofchunks> [-p <chunknumber to re-download>] [--help]

Note: Be sure that "num of chunks" is same as the previous failed download.

The script searches for number of ips that are free in the subnet and starts assigning them. Here, make sure that is the number of user ids (of you and your friends) you have.

After assigning the ips to the host, the main part is to login into cyberoam from each ip. Presently, this is being done by taking input from user and wrong password will be prompted.

Once all ips are logged in, the final step is that the file starts downloading. Once completed, the part files are joined into the single file and automatically logs out from cyberoam.

Problem: One of the ip's data was finished in between the download. What to do?

Solution: No problem, the script rechecks all the files for status and if not finished, it asks the user what to do.

Problem: I accidentally quit the script in the middle of download, what to do?

Solution: No problem, just run the script again with the same parameters as before. The script checks for any previous instances of the downloaded file.
