||ConMan: The Console Manager
conman [OPTION]... [CONSOLE]...
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 configuration,
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.
The following escapes are supported and assume the default escape character
- 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
- 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 terminated.
- -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 (i.e., lines beginning with a '#') are ignored.
- Display a summary of the command-line options.
- 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.
- Display license information.
- Monitor a console (read-only).
- Query conmand for consoles matching the specified names/patterns.
Output from this query can be saved to file for use with the '-F'
- Enable quiet-mode, suppressing informational messages. This mode can be
toggled within a console session via the '&Q' escape.
- Match console names via regular expressions instead of globbing.
- Enable verbose mode.
- Display version information.
The following environment variables override the default settings.
- Display a list of currently available escapes.
- Terminate the connection.
- Send a single escape character.
- Send a "serial-break" to the remote console.
- Toggle echoing of client input.
- Switch from read-only to read-write via a "force".
- Display information about the connection.
- Switch from read-only to read-write via a "join".
- Replay up the the last 4KB of console output. This escape requires the
console device to have logging enabled in the conmand
- Switch from read-write to read-only.
- Toggle quiet-mode to display/suppress informational messages.
- Reset the node associated with this console. This escape requires a
"resetcmd" to be specified in the conmand
- Suspend the client.
The client/server communications are not yet encrypted.

- Specifies the hostname or IP address at which to contact conmand,
but may be overridden by the '-d' command-line option. A port
number separated by a colon may follow the hostname (i.e.,
host:port), although the CONMAN_PORT environment variable takes
precedence. If not set, the default host [127.0.0.1] will be used.
- Specifies the port on which to contact conmand, but may be
overridden by the '-d' command-line option. If not set, the default
port  will be used.
- The first character of this variable specifies the escape character, but
may be overridden by the '-e' command-line option. If not set, the
default escape character [&] will be used.
