== Physical Infrastructure ==
[[Infrastructure:Cyberdelia |Cyberdelia]] is the only connected physical machine right now. It contains 48 GB of memory with 4 ethernet interfaces; only eth4 is connected and is attached to br0. All hosts are on the ECE network behind router.ece.vt.edu, a gateway featuring ARP proxying but no IPv6. For global DNS changes under ece.vt.edu, server room access, and getting hosts added to the ARP proxy, contact Branden McKagen.
Virginia Tech has started blocking inbound ports 22 and 3389 and outbound port 25 at the campus border, in a move some are calling [[gp:Cyber Auschwitz|Cyber Auschwitz]]. Contact itso-g@vt.edu for firewall exceptions. When deploying new hosts, make ssh listen on both 2222 and 22. Acidburn currently listens on 443 as well.
== On the Network Architecture ==
Because VTLUUG infra no longer has IPv6 access, we are limited by the IP addresses assigned to us, and what we can get through DHCP from ECE. As a consequence, all services which do not need to have a global IP should move to the internal network on the 10.99.x.x/24 subnet. In the future, it may be wise to bridge this network to an ethernet port on cyberdelia, so that a switch can be used to network our other services. When we have rackspace to do so, VPN/[[Iodine]] access to the internal network will be necessary.
