Traven Network Configuration
Traven is on the 18.104.22.168/25 subnet, gateway 22.214.171.124.
We are currently allocated 191-197, 248-249, 251-253
Apache is set up to use wild cards for http and https, this means that you can't test stuff using IP addresses before dns switches are made, the way around this is to edit your /etc/hosts file locally.
Sites awaiting allocation
- IMC Poland
- IMC Euskal-Herria
- IMC Bolivia (to be moved from the dutch mir server)

- IMC Qollasuyu (to be moved from kosmos)
Traven has two network interfaces, eth0 and eth1. Currently only eth0 is physically connected. Its primary IP address is 126.96.36.199, and this is what is in DNS for traven.indymedia.org
We're not sure which network interface the IPMI card talks to -- it might require eth1 connecting. We might also prefer to have it using a different interface to the main one -- possibly on a physically separate network that is only accessible from other trusted machines in the rack.
As an aside, some very odd behaviour occurred with an earlier configuration, where .249 was assigned to eth1, but nevertheless the machine responded on that IP even though eth1 had no physical connection (ie presumably eth0 was issuing bogus ARP responses for .249, and the kernel was accepting packets addressed to that IP on the wrong interface...)
This is configured from /etc/init.d/iptables, which is run during boot prior to bringing up the network interfaces. Essentially it allows only ssh, www and https traffic, plus munin from the local subnet.
