Debian Vserver cheat sheet

09 Mar 2010

This is just to keep track for myself on how to create a Vserver with Internet connectivity.

Create the network interface Edit /etc/network/interfaces and add:

auto dummy0
iface dummy0 inet static address 192.168.50.1 netmask 255.255.255.0

Restart the network /etc/init.d/networking restart

Turn the NAT on

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Replace eth0 with the network interface you use for your network access.

Create the VM sudo vserver build build -n cyrus2.3 -m debootstrap --netdev dummy0 --interface 192.168.50.2/24 -- -d lenny

Enter the VM

sudo vserver cyrus2.3 start
sudo vserver cyrus2.3 enter
