  Hello,

No problems here running nagios 2.5 inside a Debian Etch Vserver.
Processes inside a vserver cannot listen to other ip adresses anyway.

The only exeption to this are _ping_ requests on _multihomed_ machines. I
cannot ping from inside a vserver with several network interfaces. (my
firewall at home has the DMZ as vservers.)

You need to be careful on the outer machine and should put "listen
only" directives on all network services, and also limit services to
the bare minimum on the outer machine.
