Free server software for linux

The SME Server server and gateway is free software (also referred to as open-source software) and is freely available for anyone to download.
This software is brought to you by the community and contribs.org. Many individuals and organizations (both commercial and non-profit) use the SME Server as their primary network server and gateway.
We would like to remind you that the SME Server software is licensed under the General Public License (GPL). This means that if you alter the software and distribute the altered version, you must make the source code for your altered version freely available.
The GPL is a large part of why free software has made such an impact on the commercial scene. By restricting anyone from making proprietary modifications, the GPL ensures that improvements find their way back to the original code base, thereby creating an explosive rate of technical advance.
The difference between traditional development and GPL development is the difference between a light bulb - where output is radiated in many directions - and a laser - where output is reflected back in a coherent way to produce a greater, more focused result.
Its main design focus is simple, centralized configuration, along with security and ease of installation.
Enhancements:
- This release is based on CentOS 4.5 and all packages have been updated to the latest releases. This release contains many new features, all released updates for SME Server 7.1 and fixes for many reported problems. Upgrades will be available by CD, the Software Installer and command line. All users should upgrade to this release.

Video server is a streaming video server which feeds a Java applet/application for display. The updates are rather slow, somewhere in the 10 frames/second range on a PIII. The server is written in Bigloo scheme and C. The client is written in Java.

To bring up the video server you have to do the following.

./vs --channel 25 --sd 12 --input 0

./vs --help
for more options. (This seems broken with the newest version of bigloo .... )

How to bring up a java client to connect to a server:
Insure that video/java is in your classpath, and invoke

java vpanel servername

GTK-server enables access for shellscripts & interpreted programming languages to apps using either GTK 1.x or 2.x.

GTK-server project is a standalone binary, which is able to communicate by a 2-way pipe or by a TCP/UDP port. The script invokes this binary, sets up a pipe or a TCP/UDP connection and prints the GTK call in plain text to the pipe or socket. The GTK-server then sends information back which can be used in the program or script.

Below a summary of advantages when using the GTK-server:

- No need to learn C or C++, you can stick to your favorite programming language
- No need to hack the source of existing programming languages to realize GUI programming
- High flexibility in creating GUIs, e.g. not limited to dialogs
- Full GTK API available, the user can extend the gtk-server.cfg file by himself
- Access to both GTK 1.x and GTK 2.x
- Convenient GTK test tool, easy to learn GTK programming.

Tail server allows you to export the output of a "tail -f" command of a log file to a TCP port, allowing it to be viewed remotely with telnet. Tail Server provides a regular expression filter to include or exclude output view.
In several circumstances the need to access on remote time-varying log file leads to write some simple scripts.
These files generated by applications like syslog, http, news, etc. are often located on different machines.
System Administrator usually logon on remote system then type:
# tail -f filename
Tail Server offers the possibliy to map on Tcp/Ip port the output of "# tail -f filename" without (each time) logging on remote systems.
Also offers output regular expressions filter in order to include or exclude strings.
Enhancements:
- Server Log File has been implemented.

pDonkeyS is Perl implementation of an eDonkey server. The main goal of the server is to provide framework for further eDonkey protocol exploration, but it could be useful in testing of client software, since the server can be configured to output very detailed debugging info about eDonkey traffic.

This server was made to provide framework for further eDonkey protocol exploration, but it could be usefull in testing of client software, since the server can be configured to output very detailed debug info about eDonkey traffic.

Graffiti Server is a small C program that allows the posting of messages and, optionally, HTML. It displays the most recent messages but has a search function for finding entries with a given keyword or string.

The administrator connects from the local host using IP address 127.0.0.1 and delete messages from any IP.

You can search for any text string and the graffiti server will match against all old messages, as well as new ones, and return those that match.

Right click here and select save... to download a gzipped Linux binary. Right click here for the gzipped source for the graffiti server. The binary is only 45K[2] bytes and the source is only 9K in size (compressed).

To install it, simply gunzip the binary and run it with one of the following commands, then install the same command in your startup files. For example, in many Linuxes, you can put the command in /etc/rc.d/rc.local and it will be executed on each startup.

The general syntax is:

graffiti [port] [directory] [!]

The first argument is the port. If there is only one argument, it must be a port number.

The second argument is a directory name.

The third argument, if present and an exclamation point (!) tells graffiti to allow html postings.

Command examples:

graffiti

(The above will attempt to use port 80, the standard WWW port, will put its files in /var/tmp/ and will disallow html.)

graffiti 7777

(This command will do everything just like the command before it, only it will attempt to use port 7777 instead of 80.)

graffiti 8888 /home/rayy/graffiti/

(This command will put the files in /home/rayy/graffiti/ and will try to run on port 8888.)

graffiti 9999 /home/rayy/graffiti/ !

(This one will, again, put the files in /home/rayy/graffiti but will use port 9999, and will allow html entries.)

The data files take about 1 megabyte but will hold about 2500 graffiti entries, as configured.

If a file named wg####.txt is present in the data files directory, the Graffiti Server will display that file on every page. [Where #### is the port number the Graffiti Server is running on]. You can run as many copies of the graffiti server as you wish on separate ports. Because each copy puts its port number in its file names, there will be no file conflicts.]

Dystopia is a Half-Life 2 modifcation which places the player into tense combat situations in a high tech world spanned by computer networks. As either Punks or Corp Mercenaries the player will fight through the physical world to gain access, via jack-in terminals, to cyberspace.

Cyberspace is a three dimensional representation of the worlds network. Inside cyberspace players will launch programs to hack into systems linked to the physical world, fight off enemy hackers or defend critical systems. Gameplay progresses through inter-linked physical and cyberspace objectives, some are completed in either the physical world or cyberspace, others only by a well timed combination of the two.

The player will be immersed in action packed battles, whether as a heavily augmented combat mercenary armed to the teeth with the latest in firepower and implants, or a twitch reflex cyberdecker racing to infiltrate a cyberspace node. Only through skillful use of the high tech arsenal were making available and intelligent team play will players truly jack-in and kick ass.

Note: System used was Ubuntu Breezy Badger 2.6.12-9

Installation:

Log in as root

Create a user (EX. hlds, dystopia, srcds, etc..) with the command:

adduser hlds

Give that user a password

passwd hlds

Create a directory somewhere as that user where the server files and game files will go and go to that directory

mkdir /home/hlds/srcds

Make the owner of that directory your new user

chown hlds /home/hlds/srcds

Either login as that user or change to that user with the command

su hlds

Get the linux hlds update tool accurate as of 2/22/07

wget http://storefront.steampowered.com/download/hldsupdatetool.bin

Change the file to be executable

chmod ugo+x hldsupdatetool.bin

Run the hldsupdatetool.bin

./hldsupdatetool.bin

If you see an error about not finding /bin/uncompress type

ln -s /bin/gunzip /bin/uncompress && ./hldsupdatetool.bin

Answer the agreement
Run the steam file that is extracted

./steam

It will update itself and then tell you to rerun the command, do so, but changed. This will take a while

./steam -command update -game hl2mp -dir .

Download the Dystopia V1 server package

wget dystopia_v1_server.tar.gz

Extract the files in your srcds folder

tar -xvzf dystopia_v1_server.tar.gz

Configuration:

Edit ~/srcds/dystopia/cfg/server.cfg with your editor of choice. This file is run at every map change.

Comment out or remove the following line.

map dys_assemble

This must be done or you server will not start properly.
Edit ~/srcds/dystopia/cfg/valve.rc with your editor of choice. This file is run at server start

Add in the line the following line.

map dys_assemble

This map can be whatever you like your server to start on. If you do not do this, your server will not start properly.
Edit ~/srcds/dystopia/motd.txt with your editor of choice
Edit ~/srcds/dystopia/mapcycle.txt with your editor of choice

Starting the Server - Basic

Go to your srcds directory, whatever it is named

cd ~/srcds

Use the following command to start your server, this is a basic setup, replace 1.1.1.1 with the ip you want your server to report. You can also leave out the +ip 1.1.1.1 and it will take the first IP it can get

./srcds_run -game dystopia_v1 +maxplayers 20 -ip 1.1.1.1 -port 27015 &

To bring the console back so you can type commands into the console. use the command

fg

This will not always work.

The drawback to this method is that once you start it and then exit your ssh session you will not be able to get it back (at least I dont know of a way, if you do, let me know and Ill add it)

Starting the server - Advanced

Check to see if you have the screen command

screen

If you do, proceed, if not, get it. Create a shell script with the following commands. To do so, open a file in your favorite text editor (*nix only please). I named the file serverStart.sh

#!/bin/sh echo "Starting Dystopia Beta Server" sleep 1 cd /home/hlds/srcds screen -A -m -S dystopia /home/hlds/srcds/srcds_run -game dystopia_v1 +maxplayers 20 -ip 1.1.1.1 -port 27015

Make the shell script executable

chmod ugo+x serverStart.sh

Once its up and running, to exit the screen without closing it use the following key combo

ctrl+A,D (ctrl+A and then while still holding a, press d)

To retrieve the screen so that you can look at the console

screen -r
