3 cec \- Coraid Ethernet Console
28 uses raw Ethernet packets to connect to a CEC server for console access.
29 All clients share the same session.
30 Coraid appliances and Coraid Plan 9 kernels can currently be CEC servers.
33 starts by probing the specified network interface
34 for available CEC servers. The default is
38 process may be run per Ethernet interface.
39 If the server is specified with the
44 options, communication will
45 proceed immediately upon discovery of the first CEC server
46 with the specified address.
47 Otherwise, a selection prompt
48 will be displayed showing the discovered CEC servers
49 available for communication. Unless the
53 exits if no matching servers are found.
54 The selection prompt accepts
61 (from the first column),
64 Probe the interface again, and
70 Note the selection number is not the shelf address but the
72 sequence number printed in the leftmost column.
74 Once connected to a CEC server, typing the escape character
75 will drop the user into an escape prompt where the user may type
77 to quit the connection,
79 to send the escape character
80 across the connection, or
82 to continue the connection.
86 Set the escape character to
88 The default setting is control-\e.
91 Print debugging information.
94 Connect to the server with Ethernet address
100 Connect to the server
102 Note that this name might not be the same as the contents of
104 on the target system.
107 Persist: continue trying to connect even if
108 there are no matching servers. This is useful when
109 connecting to a CPU server before it boots.
112 Connect to the server at address
116 Post the CEC connection as
127 will exit upon closing the connection.
130 will return to the selection prompt upon connection close.
149 The CEC protocol should be integrated with the console server.
150 The arbitration between the keyboard and network is suboptimal.
152 Early boot information and very late crash information from servers
153 may be lost due to timing quirks.
