Debian Vserver cheat Sheet

This is just to keep a trace 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


Turns the NAT on

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

eth0 here is 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
