NAME

cec – Coraid Ethernet Console

SYNOPSIS

cec [ –d ] [ –s shelf ] [ –e esc ] interface

DESCRIPTION

The cec command uses raw Ethernet frames to connect to a CEC server for console access. All clients share the same session. Coraid appliances are currently the only CEC servers.
A cec process starts by probing the specified network interface (e.g., /net/ether0) for available CEC servers. If the shelf address of the server is specified with the –s flag, the connection will proceed immediately upon discovery of the first CEC server with this shelf address. Otherwise, a selection prompt will be displayed showing the discovered CEC servers available for communication. If no servers are discovered, cec exits.

The selection prompt accepts
number

Connect to server number (from the first column),

p     Probe the interface again, and
q     Quit.
Note the selection number is not the shelf address but the cec–generated ID number printed in the leftmost column.
Once connected to a CEC server, entering the escape sequence will drop the user into an escape prompt where the user may type q to quit the connection, i to send the escape sequence across the connection, or . to continue the connection. The escape sequence is printed on connection.
If the –s option is used, cec will exit upon closing the connection. Otherwise, cec will return to the selection prompt upon connection close.

Options
–d          Output debugging information.
–s shelf      Connect to the server at shelf address shelf.
–e esc       Set the escape caracter to control– esc. The default setting is control–\.

	The CEC protocol should be integrated with the console server. The arbitration between the keyboard and network is suboptimal.
