Asunto: Outbound traffic spike every 30 minutes
Enviado: 3 de dic de 2013 19:36
Since Sunday morning, one of my CentOS servers has been generating a
small spike of outbound traffic every 30 minutes (X:00 and X:30). It's
not enough traffic to really cause any notice except for the fact that
it is a very regular pattern and it started abruptly at midnight Sunday.
This server is used for mail (Courier-MTA), and DNS (Bind). I cannot
find anything unusual in either of those logs. I tried grepping through
my firewall logs, but have been unable to find anything useful there
either. I don't see any cron jobs that would generate network traffic.
Any suggestions how I can go about tracking this down?
