CONMAN(1) LLNL CONMAN(1)
NAME
conman - ConMan client
SYNOPSIS
conman [OPTION]... [CONSOLE]...
DESCRIPTION
conman is a program for connecting to remote consoles being managed by
conmand. Console names can be separated by spaces and/or commas.
Globbing is used by default to match console names against the configu-
ration, but regular expression matching can be enabled with the ’-r’
option.
conman supports three modes of console access: monitor (read-only),
interactive (read-write), and broadcast (write-only). If neither the
’-m’ (monitor) nor ’-b’ (broadcast) options are specified, the console
session is opened in interactive mode.
OPTIONS
-b Broadcast to multiple consoles (write-only). Data sent by the
client will be copied to all specified consoles in parallel, but
console output will not be sent back to the client. This option
can be used in conjunction with ’-f’ or ’-j’.
-d destination
Specify the location of the conmand daemon, overriding the
default [127.0.0.1:7890]. This location may contain a hostname
or IP address, and be optionally followed by a colon and port
number.
-e character
Specify the client escape character, overriding the default [&].
-f Specify that write-access to the console should be "forced",
thereby stealing the console away from existing clients having
write privileges. The original clients are informed by conmand
of who perpetrated the theft as their connections are termi-
nated.
-F file
Read console names/patterns from file. Only one console name
may be specified per line. Leading and trailing whitespace,
blank lines, and comments (ie, lines beginning with a ’#’) are
ignored.
-h Display a summary of the command-line options.
-j Specify that write-access to the console should be "joined",
thereby sharing the console with existing clients having write
privileges. The original clients are informed by conmand that a
new client has been granted write privileges.
-l file
Log console session output to file.
-L Display license information.
-m Monitor a console (read-only).
-q Query conmand for consoles matching the specified names/pat-
terns. Output from this query can be saved to file for use with
the ’-F’ option.
-Q Enable quiet-mode, suppressing informational messages. This
mode can be toggled within a console session via the ’&Q’
escape.
-r Match console names via regular expressions instead of globbing.
-v Enable verbose mode.
-V Display version information.
ESCAPE CHARACTERS
The following escapes are supported and assume the default escape char-
acter [&]:
&? Display a list of currently available escapes.
&. Terminate the connection.
&& Send a single escape character.
&B Send a "serial-break" to the remote console.
&F Switch from read-only to read-write via a "force".
&I Display information about the connection.
&J Switch from read-only to read-write via a "join".
&L Replay up the the last 4KB of console output. This escape
requires the console device to have logging enabled in the con-
mand configuration.
&M Switch from read-write to read-only.
&Q Toggle quiet-mode to display/suppress informational messages.
&R Reset the node associated with this console. This escape
requires a "resetcmd" to be specified in the conmand configura-
tion.
&Z Suspend the client.
ENVIRONMENT
The following environment variables override the default settings.
CONMAN_HOST
Specifies the hostname or IP address at which to contact con-
mand, but may be overridden by the ’-d’ command-line option. A
port number separated by a colon may follow the hostname (ie,
host:port), although the CONMAN_PORT environment variable takes
precedence. If not set, the default host [127.0.0.1] will be
used.
CONMAN_PORT
Specifies the port on which to contact conmand, but may be over-
ridden by the ’-d’ command-line option. If not set, the default
port [7890] will be used.
CONMAN_ESCAPE
The first character of this variable specifies the escape char-
acter, but may be overridden by the ’-e’ command-line option.
If not set, the default escape character [&] will be used.
SECURITY
The client/server communications are not yet encrypted.
