-The only machine that can be reached from outside the testbed (but still only from within certain networks) is the head node.
+The only machine that can be reached with ssh from outside the testbed is the management node '''bleek.nikhef.nl'''. Inbound ssh is restricted to the Nikhef network. The other testbed hardware lives on a LAN with no inbound connectivity. Since bleek also has an interface in this network, you can log on to the other machines from bleek.
-The testbed lives on a LAN with no inbound connectivity. The management host '''bleek.nikhef.nl''' is the entry point to the entire testbed. It takes care of network address translation (NAT) of the 10.198.0.0/16 range used inside the testbed, resolving hostnames and handing out ip addresses (with dnsmasq), serving home directories, and serving VM installation details such as kickstart files (Red Hat/Fedora) and preseed configurations (Debian).
 Access to bleek.nikhef.nl is restricted to users who have a home directory with their ssh pulic key in ~/.ssh/authorized_keys.
