Hi,

If a container is granted the cap_net_admin capability on a venet0 device, can it do anything dangerous (like mess around with routing tables for other CTs or the host, or forge mac addresses)?

Thanks.

I suggest you to DO NOT allow ANY of your vps client to use this function. Probalby there is a bug with this function. OVZ is buggy.

Hi,

Thats not very helpful. It doesn't answer the question, just makes a vague statement about the stability of openvz - which I don't agree with.

What is cap_net_admin for?

I have enabled this cap for one client. Next day someone has hack admin pass do hypervm... before that he created vps with default config and mess up a little on nodes... net_admin allows to manage ips and routing table, maybe more...
