Without physical access to the server for NTOP flows session, go for tshark (tcpdump with ring buffers) for a day and see what's up. You can pull the PCAP file down to your lcoal and run ethereal or NTOP or other analysis tool from there.

All, I have a leased server I use to host some websites and for the past week I have been getting traffic warnings. The server has been transferring > 1GB of data per day, which is unusually high, especially since I moved my mail to Google Apps. I have noticed a ridiculous amount of attempted proxying attemptes in my logs, but I do not have mod proxy turned on. I suspect my server is on some list. I firewalled off a large number of subnets from China and my traffic dropped for a few days, then this morning, 2735MB transferred in 24 hrs. As of right now, I am planning to blackhole all China traffic, since thats where most of this is comming from, along with the occasional traffic from France and other places in Eur. Is this common? If so are there any other remedies?
