gems-server - Transmit a shell session in real time.
gems-server [-ip ip] [-port p]
[-maxconn n] [-wait m] [-log dest]
[-noscript] [-script_bin script]
gems-server -h | -v
Transmits a shell session to be shown in real time in various
different computers or terminals.
gems-server transmits data in real time to clients via a
network connection. Each one of these clients must run the
gems-client(1) program to establish connection and receive the
transmitted data. Clients can connect and disconnect at any given time, but
of course they will only receive the data that is transmitted while they are
connected (just like a radio transmission/reception system).
The gems system is normally used to transmit a console session and
show it in various computers at the same time, but it is also possible to
transmit any other kind of data.
- -ip
- IP address where connections will be accepted.
- -port
- TCP port. Default: 6666.
- -maxconn
- Do not accept more than n simultaneous clients. Default: 25.
- -wait
- Wait until m clients are connected before starting the
transmission. This is useful to ensure that the first m clients
will receive all data transmitted. The default behavior is to start
transmission immediately, without waiting for client connections.
- -log
- By default, the server does not write log messages. This option configures
the destination of logs. The dest argument can be `syslog' (to log
through syslogd(8)), `stderr' (to log through standard error
output), or it can be an arbitrary filename (log messages will be appended
to the file, if it exists).
- -noscript
- By default, the server executes the script(1) program to take
terminal data and transmit it. When this option is used the server will
not run script, and data will be read form standard input.
- -script_bin
- Specifies the location of the script(1). program. Default:
/usr/bin/script.
- -h
- Show a short help message.
- -v
- Show version information.
- /var/lock/gems-server.PORT
- Lock file. gems-server creates this file on initialization and
deletes it on exit. PORT is replaced by the TCP port used.
gems-server will not run if this file is already present in the
system.
