Hi Vagrant,

The server and clients do have static ip addresses;
my  /etc/network/interfaces file is;

auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 192.168.0.253
netmask 255.255.255.0
gateway 192.168.0.1
up iptables -t nat -A POSTROUTING -o $IFACE -j MASQUERADE
auto eth0
iface eth1 inet static
address 192.168.1.253
netmask 255.255.255.0
gateway 192.168.0.1
auto eth1
interfaces (END) 

my /etc/hosts file is;
127.0.0.1 localhost localhost.localdomain localhost localhost
c2d.localhost
192.168.1.253 c2d.localhost
# The following lines are desirable for IPv6 capable hosts
ff02::3 ip6-allhosts ip6-allhosts
## LTSP-begin ##

Thats correct, I do only have to run ltsp-update-sshkeys to get the
clients to log in.
