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.
