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.
