    I have recently installed sarge via net install using the 2.6 kernel, then i patched the kernel with the vserver

    i made a vserver and started it, then i copied my apt lists to it but when i enter the vserver i cannot use anything over the net like ping or apt-get

    apt-get update says connecting and times out

    What's in
    Code:
    /etc/resolv.conf
    in the vserver, and what's the output of
    Code:
    ifconfig
    on the vserver?

    Did you use Xen or the Linux Vserver project?

    Ok, it doesn't seem to be a DNS problem as pinging the IP address doesn't work either.
    It really seems as if you don't have a network connection. I had this problem as well with the Linux Vserver project (and haven't found a solution yet...).
    But maybe it's only your firewall. Please post the output of
    Code:
    iptables -L
    on your vserver and also on the host system.
    Can you ping the vserver from the host system and vice versa?

    host:

    # iptables -L
    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    i got it to work:

    iptables -t nat -A POSTROUTING -s 192.168.2.1 -j SNAT --to-source 192.168.1.130

    external pings and apt-get update work now

    so now my question is can you have a webserver or any kind of server running in more than one vserver if so how would i make it so when you goto

    www.domain.com it goes to vserver 1 or if i goto
    test.domain.com it goes to vserver 2

    This is possible if your vservers all have public IP addresses - you'd just have to create the appropriate DNS records.

    However, you seem to use private IP addresses. In this scenario it's not possible. This is the same as if you have a router, and behind that router you have a local network with your servers. You can forward port 80 from your router to only one server, not to multiple servers.
