Xen users - May 2009 - will it effect other vps if one vps is attacked.

Hi,
Today, my server is attacked, but it shows every vps have a large
traffic, does it mean every vps is attacked? or just one vps is
attacked, and the traffic is count incorrect?

Thanks.

What do you mean "is count(ed?) incorrect(ly?)"? Who''s
counting it? I
guess you are talking about another software here.

What kind of attack are you experiencing?

To my experience, a normal DoS firewall to avoid flood is a must have in
production, otherwise it''s quite easy to eat all the CPU of a server.

For the "counting" of your VPS traffic, well under Xen, we use the
normal byte counter in /proc, and it''s working pretty well.
