NAME
gems-server - Transmit a shell session in real time.
SYNOPSIS
gems-server [-ip ip] [-port p] [-maxconn n] [-wait m] [-log dest]
[-noscript] [-script_bin script]
gems-server -h | -v
DESCRIPTION
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.
OPTIONS
-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.
FILES
/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.
