Operating Systems Linux How To Open Ports in RedHat ? Post 39968 by cbkihong on Saturday 6th of September 2003 04:33:53 AM

What do you mean by opening a port?

If an application server binds to the port to listen incoming traffic or have to send out any messages, the port must be open. Otherwise, it is closed. I don't think you will manually open a port.

Or do you mean to configure the firewall to enable certain ports that are otherwise blocked by default?

NAME
bubbros-client - the bub-n-bros client SYNOPSIS
bubbros-client [ options ] [host[:port]] DESCRIPTION
This is the bub-n-bros client that connects to bub-n-bros servers started with bubbros-server(6) or bubbros(6). It supports many different audio and video drivers and is very multi-platform. OPTIONS
host Search for a game on the given machine, and connect to one if found. If this is not defined, search for servers on the local net- work. host:port Connect to server running on given port on given host. If this is not defined, search for servers on the local network. --bits=N This option concerns only the windows audio driver. Set bits per sample. Valid values are 8 and 16 (default). -d DRIVER, --display=DRIVER Use video driver DRIVER. Valid drivers are: X X Window driver for Linux and Unix systems with an X server running. See the --shm option. windows MS Windows driver. pygame PyGame gaming library for python (if installed) has video output. Use it if this is specified. See http://www.pygame.org and the --transparency option. gtk Use the PyGTK library (if installed). See http://www.pygtk.org/ and the --zoom option. -h, --help Display help. --fmt=format This option concerns only the linux audio driver. Set the sound data format. Defaults to S16_NE. You can get a list of supported formats with --fmt=list. --freq=N This option concerns only the linux and windows audio drivers. Set mixing frequency to N (in Hz). Defaults to 44100. -m, --metaserver Connect with the help of the Metaserver (see bubbros-server(1) for more info). Run bubbros-client -m to print a table of currently running servers, pick the the exact IP address and port of the server of your choice from the table, and run again bubbros-client -m host:port. --port TCP=port In conjunction with the -m option, force a specific port on which to listen for an incoming TCP connexion from the remote server. This is only used if a direct connexion to the server fails. A random port number is picked by default. This option is useful if you are behind a firewall but can let TCP connexions on specific ports reach you. --port UDP=port Force a specific port on which to listen for incoming UDP traffic (animation data). Useful if you are behind a firewall but can let UDP traffic on a given port pass through. This is optional: animation data is routed over the TCP link if it does not appear to reach the client. A random port number is picked by default. -s DRIVER, --sound=DRIVER Use driver DRIVER for audio. Valid drivers are: pygame Use the audio capabilities of the PyGame library (http://www.pygame.org). linux Use the linux audio mixer. See the --freq and --fmt options. windows Use the Windows audio mixer. See the --freq and --bitsoptions. off No sounds. --shm=yes, --shm=no This option concerns only the X display driver. Disable or enable the shm (Shared Memory) extension. It is enabled by default and should only be disabled for remote X connections and old X servers. -t Use the TCP protocol. The default is to autodetect the protocol. See the -u option. --transparency=yes, --transparency=no This option concerns only the pygame display driver. Disable or enable transparent bubbles. Enabled by default. Disabling makes game a bit faster. -u Use the UDP protocol. The default is to autodetect the protocol. See the -t option. --zoom=N% This option concerns only the gtk display driver. Scale output by N%. SEE ALSO
