When I try to dump some traffic on my vserver's network interface, I get an error that I'm not allowed to do that:
# tcpdump -p -i eth0
tcpdump: eth0: You don't have permission to capture on that device
(socket: Operation not permitted)
I guess the problem is that my server provider seems to use a virtualization solution with shared Linux kernel (uname returns "2.6.33.7-vs2.3.0.36.30.4-netcup" as version).
Any way that allows me to dump outgoing traffic from a single process?
