Heavy data transfer from Cpanel server
One of my Cpanel servers is showing heavy data transfer this month. In 6 days, it crossed 600 GB data transfer which is equal to what it did last month. Also, all the websites collectively have only consumed around 60 GB data transfer in 6 days. How do I find out what exactly is causing heavy data transfer?

How does the bandwidth usage looks like for individual domains ? .
Probably hostlinking or videos being used by external servers .

As per the datacenter's monitoring system, the bandwidth usage is due to outgoing bandwidth and according to bandmin installed in the server, it is due to UDP.

Does that server have a root domain? If so, check it as well as that is where the leeching could be.

Is your company website hosted on the affected server? If so then check your own account as it may be compromised. The root domain is the one associated to you with root access.

Are you running cPanel FTP Backups or something similar?
If a user has uploaded a significant amount of data, it's highly possible that it would be your nightly remote backups causing a massive jump in bandwidth usage.█ Matthew Rosenblatt, and I do lots of things.

Hey,
Does any of your clients has shell access ? Does any of the site hosted
has some sort of torrent sharing things ? Meanwhile what does bandwidth usage shows in WHM for each domain ?Regards,

None of the websites shows enormous bandwidth usage. I have not given shell access too to any account.

How can I find out what was the network activity at a specific time on the server? Is there some log for the network activity created somewhere in linux?
