How do I remotely turn on or off a server?

This page is intended for MFPL admins only.

All power units are configured to list the name of the server connected to each port (we don't maintain a list on this page).

To power down a server, first determine if the server is in Telehouse or Bandcon. Then, login to each power unit in the location and get a status listing to see if the server you want to power down is controlled by the power unit you are connected to.


In Telehouse, we have two Baytech RPC devices, each with 8 ports: gabriel (RPC4) and karl (RPC3).


Connect to gabriel:

cereal attach gabriel

Connect to karl:

cereal attach karl

In our XO/Bandcon space we have two Baytech RPC-27 zero U devices named odetta and ochs.



Followed by either:

connect direct deviceport odetta
connect direct deviceport ochs

Wiring details

Thanks to Riseup for setting up our cables. Here are the details for creating an RJ45 to RJ45 cable that properly connects a Lantronix Serial Console server to the Baytech RPC-27 device.

| this end plugs into the lantronix (where x is no wire):
| x/WBr/WBl/O/x/Bl/WO/x   = 1/2/3/4/5/6/7/8

| and the other end (plugs into the baytech) is the standard 568B:
| WO/O/WG/Bl/WBl/G/WBr/Br = 1/2/3/4/5/6/7/8

| Baytech   ->  SLC
| 1 (DTR)  ->   7 (DSR)
| 2 (GND)  ->   4 (GND)
| 3 (RTS)  ->   x
| 4 (Tx)   ->   6 (Rx)
| 5 (Rx)   ->   3 (Tx)
| 6 (N/C)  ->   x
| 7 (DSR)  ->   2 (DTR)
| 8 (DCD)  ->   x

Creating new users on odetta

Some notes from Riseup on creating new users:

  • The max password length appears to be 8 characters, doing a longer password results in an "Invalid password" error.
  • To set a password what you have to do is to create the user as 'admin', then logout of the 'admin' account and then login to the new user account (with no password), then run the 'password' command as that user.
  • By default all new users have access to no recepticles.
