sniffing with tcpdump [message #39379]

Hi,

I'm trying to use tcpdump in the VE, but I read in the wiki that it is only possible with VETH (http://wiki.openvz.org/Differences_between_venet_and_veth)

To make sure I'm not using VENET I removed it from the modules loaded by /etc/init.d/vz, but now I get the following error message:

Quote:

unable to open proc/vz/veinfo

(As reported in this thread)

I read here that the venet module has to be loaded in order for the veinfo file to be created.

How can I be sure I use veth ?

Thanks Smile

Ok, now I'm sure I use veth, as I have unloaded the venet module. OpenVZ is working despite the /proc not found file error.

But I still can't sniff packets in promiscuous mode, ie I see broadcast packets and packets destined to me, but not the other ones.

Has anyone ever managed to do this ?

Regards
