== How do I connect to a Telehouse server via the serial port? ==

At Telehouse, 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 a getty for Octavia itself. The second built-in serial line is going to shadow. The remaining 8 serial lines are connected to other servers in our rack.

 * Out:
  * octavia getty (built-in serial console 1, octavia: ttyS0)
 * In:
  * shadow (built-in serial console 2, sylvia: ttyS0)
  * viewsic (octopus 1, sylvia: tty8)
  * malcolm (octopus 2, sylvia: ttyS8)
  * chavez (octopus 3, sylvia: ttyS8)
  * gramsci (octopus 4, sylvia: ttyS8)
  * sontag (octopus 5, sylvia: ttyS8)
  * menchu (octopus 6, sylvia: ttyS8)
  * leslie (octopus 7, sylvia: ttyS8)
  * evo (octopus 8, sylvia: ttyS8)

In order to connect via serial console to one of the servers named above, ssh into sylvia with the appropriate user name based on:

servername-console

For example:

{{{
ssh shadow-console@sylvia.mayfirst.org
cereal attach shadow
}}}

Would give you full read/write access to the console on shadow.

We can also setup additional users that have read-only access to the sessions created by each of these usernames.
