Computers

ftbfs.org is comprised of two computers:

I'd like to improve the configuration of these systems, so if you have any information that could help me to do so, please send it to kraai@ftbfs.org.

The website is served by the Xen virtual machine.

Email is delivered to the Xen virtual machine and then downloaded to the MacBook Pro using a system-wide fetchmail. It uses a system-wide fetchmail so that it will download the email irregardless of whether I've logged in.

IPv6

I've configured both systems to use IPv6 using tunnels from Hurricane Electric's IPv6 Tunnel Broker.

I configured the MacBook Pro to use IPv6 by adding the following to its /etc/network/interfaces:

# The IPv6 tunnel network interface
auto 6in4
iface 6in4 inet6 v4tunnel
        address 2001:470:1f04:773::2
        netmask 64
        endpoint 72.52.104.74
        ttl 64
        up ip link set mtu 1280 dev 6in4
        up ip route add default via 2001:470:1f04:773::1 dev 6in4

2001:470:1f04:773::2 is the tunnel's client IPv6 address (with the "/64" stripped), 72.52.104.74 is the tunnel's server IPv4 address, and 2001:470:1f04:773::1 is the tunnel's server IPv6 address (with the "/64" stripped).

I configured the Xen virtual machine to use IPv6 by adding the following to its /etc/network/interfaces:

# The IPv6 tunnel network interface
auto 6in4
iface 6in4 inet6 v4tunnel
        address 2001:470:27:172::2
        netmask 64
        endpoint 216.66.80.90
        ttl 64
        up ip link set mtu 1280 dev 6in4
        up ip route add default via 2001:470:27:172::1 dev 6in4
	up ip addr add 2001:470:28:172::1/64 dev 6in4

This is similar to the configuration of the MacBook Pro, except for the last line, which adds the routed /64 address to the interface.
