    11== How do I connect to an MF/PL server located at Telehouse via the serial port? ==

    3 In the MF/PL Telehouse rack, we have installed an [http://www.lavalink.com/index.php?id=232 Octopus 550] in `sylvia`, a domU that is installed on `octavia`. An Octopus 550 is a pci card that has 8 serial lines coming out of it. `octavia` already has two built-in serial lines. `octavia`'s first built-in serial line is outputting the console for `octavia` itself. The second built-in serial line is controlling `shadow`'s console. The remaining 8 serial lines are connected to other servers in our rack.

An Octopus 550 is a pci card that has 8 serial lines coming out of it. `octavia` already has two built-in serial lines. `octavia`'s first built-in serial line is outputting the console for `octavia` itself. The second built-in serial line is reserved (it will probably be used to control a power system). The remaining 16 serial lines are connected to other servers in our rack.

    1925The serial consoles of the attached machines are all remotely accessible (to properly-authenticated people), and they are also logged and timestamped.  We are using [http://cmrg.fithhorseman.net/wiki/cereal cereal] to do this cleanly and easily.
