I recently got my Linode VPS. And I have a rather low-traffic site being hosted on it. But when I look at the traffic, it has high outgoing traffic peaking at regular intervals and I am not sure what it is or how I can find out.
How could I detect what is causing this? Or what is the best tool for this?
Answer
A couple strategies that might work are outlined here:

The two ideas that I think are the best bets are:
- Catch it in the act using
topin batch mode - Turn on process accounting (pacct)
Since this seems to be happening at regular intervals, it shouldn't be too difficult to catch it at the right time.
