Hello :o)

Look at this:
lms_at_users:~$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:06:4F:01:9D:0C
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

lms_at_users:~$

eth0 *allways* appears on the vserver but you dont know its IP or any info
regarding it! Its just like if you had a ethernet interface and put'it up
without configuring it.

As you can see on my server you also see the "lo" and the "lo:user" (which
is the vserver iam running).

I choosed to bind on the loopback interface since that server is a
dedicated one, connected directly to the internet via one eth0 interface.

Since i thought *somebody could sniff the data beetween vservers* i
choosed to bind them into the lo interface! That way they can still
communicate with each other and be "secure" ;o) [would somebody correct me
on this if im wrong?]
