Developer Info
The Nway RPC and terminal server are connected to a private network that is accessible from nway1, nway2, and quadrics.sandia.gov:
192.168.254.2 rpc 192.168.254.3 terminal-server
Remote Power Control
The RPC outlets are connected as follows:
Outlet Host
------ ----------------
6 nway1.sandia.gov
7 nway2.sandia.gov
To reboot a node:
telnet rpc
// Then:
// Select "1. Outlet Control"
// Type "reboot {outlet number}"
// Type "y" to confirm
// The node should reboot
Serial Terminals
The terminal-server ports are connected as follows:
Port Host
---- ----------------
20 nway1.sandia.gov
17 nway2.sandia.gov
To access a node's serial terminal, telnet to port 20{Port} on the terminal server. For example, to access nway2's terminal type:
telnet terminal-server 2017
On a Linux node, type Enter to bring up a login prompt.
To exit the telnet session, type Ctrl-]. A ">telnet" prompt should then appear. Type "quit".
