Warsaw

Warsow is a fast paced first person shooter consisting of cel-shaded cartoon-like graphics with dark, flashy and dirty textures. Warsow is based on the E-novel “Chasseur de bots” (“Bots hunter” in English) by Fabrice Demurger. Warsow’s codebase is built upon Qfusion, an advanced modification of the Quake II engine. Set in a futuristic cartoon-like world where rocketlauncher-wielding pigs and lasergun-carrying cyberpunks roam the streets, Warsow is a completely free fast-paced first-person shooter (FPS) for Windows, Linux and Mac OS X.

Speed and movement, that’s what Warsow is all about. Like a true cyberathlete you jump, dash, dodge and walljump your way through the game. Grab those power-ups before your enemy does, plant the bomb before anyone sees you, and steal the enemy’s flag before anyone knows what’s going on!

Sauerbraten

Much like the original Cube, the aim of this game is not necessarily to produce the most features & eyecandy possible, but rather to allow map/geometry editing to be done dynamically in-game, to create fun gameplay and an elegant engine.

Sauerbraten is a networked fast-paced 3D first-person shooter game. It supports rather modern graphic effects and a some nice graphic details.
The game client also works as the map editor. It is even possible to create and/or edit a map together with other people over a network connection.
Sauerbraten might be considered unsuitable for children.

Tremulous

Tremulous is a free, open source game that blends a team based First Person Shooter (FPS) game with elements of a Real Time Strategy (RTS) game. Players can choose from 2 unique races, aliens and humans. Players on both teams are able to build working structures in-game like a Real Time Strategy game. These structures provide many functions, the most important being spawning. The designated builders must ensure there are spawn structures or other players will not be able to rejoin the game after death. Other structures provide automated base defense (to some degree), healing functions and much more.

Player advancement is different depending on which team you are on. As a human, players are rewarded with credits for each alien kill. These credits may be used to purchase new weapons and upgrades from the “Armoury”. The alien team advances quite differently. Upon killing a human foe, the alien is able to evolve into a new class. The more kills gained the more powerful the classes available.
The overall objective behind Tremulous is to eliminate the opposing team. This is achieved by not only killing the opposing players but also removing their ability to respawn by destroying their spawn structures.

proxy server

Install Squid
Install squid and squid-common

sudo aptitude install squid squid-common


Edit the squid config file.

sudo vi /etc/squid/squid.conf


Set the allowed hosts.

acl internal_network src 192.168.0.0/24 (Where 192.168.0.0/24 is your IP range.)
http_access allow internal_network

Set the correct permissions.

sudo chown -R proxy:proxy /var/log/squid/
sudo chown proxy:proxy /etc/squid/squid.conf


You will need to restart squid for the changes to take affect.

sudo /etc/init.d/squid restart

Now open up your browser and set your proxy to point to your new squid server on port 3128

Authentication
If you wish to use authentication with your proxy you will need to install apache2 utilities

sudo aptitude install squid squid-common apache2-utils

To add your first user you will need to specify -c

sudo htpasswd -c /etc/squid.passwd first_user

Thereafter you add new users with

sudo htpasswd /etc/squid.passwd another_user

Edit the squid config file

sudo vi /etc/squid/squid.conf


Set the the authentication parameters and the acl

auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid.passwd
auth_param basic children 5
auth_param basic realm NFYE Squid proxy-caching web server
auth_param basic credentialsttl 3 hours
auth_param basic casesensitive off

acl users proxy_auth REQUIRED
acl sectionx proxy_auth REQUIRED
http_access allow users

So this is what your squid.conf should look like.

acl all src 0.0.0.0/0.0.0.0

acl internal_network src 192.168.0.0/24
acl users proxy_auth REQUIRED
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443 563 # https, snews
acl SSL_ports port 873 # rsync
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl Safe_ports port 631 # cups
acl Safe_ports port 873 # rsync
acl Safe_ports port 901 # SWAT
acl sectionx proxy_auth REQUIRED
acl purge method PURGE
acl CONNECT method CONNECT
http_access allow manager localhost
http_access allow users
http_access allow internal_network
http_access deny manager
http_access allow purge localhost
http_access deny purge
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost
http_access deny all
http_reply_access allow all
icp_access allow all

Redirect the all HTTP traffic.
If you would like to redirect the all HTTP traffic through the proxy without needing to set up a proxy manually in all your applications you will need to add some rules

iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.0.1:3128
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128


Where eth1,eth0 are the LAN, WAN devices and 192.168.0.1 is the IP address of your LAN device.
If you wish to monitor the performance of your proxy you can look as some log parser’s (sarg, calamaris, ect.)

After all, probably you feel the need to monitor the performance of your proxy. Unfortunately, most of the squid log parsers in the Ubuntu repository are configured for Squid 2.x. Nevertheless, squid 3 uses the same log format, so you can change the log file path in your parser config file (sarg, calamaris, etd.) or simply link the log directory of squid 3 to the correct path

ln -s /var/log/squid3 /var/log/squid

From my experiences running a cyber cafe business and provides certain solution to the others cyber cafe owners, Ubuntu Linux 10.04 or the previous version of it, is the perfect choice to be the server and the client operating system for cyber cafe purpose.

It has everything except POINT OF SALES software, dont believe on me? try to click ubuntu main menu > Ubuntu Software Center > Search for cyber cafe and you’ll get nothing except blank white page. But try search for point of sale and you will get “lemon point of sale” but this software wasn’t meant for cyber cafe purpose, it was created for general such as restaurant or book store.

One thing until now what Open Source Operating System such as Ubuntu or perhaps I should say Canonical still couldn’t beat Microsoft is the supports from game developer, but currently i heard that Steam is coming to Linux, until now we still need to using wine and other emulators to play warcraft III, counter strike and so on.

For me, that is why the progress in running gaming center or cyber cafe business based on open source software was far too slow and just few small company had put their interest to develop a billing system or pos system for linux operating system but still their software lacks many of important features, I didn’t say I am condemns their software, for me it’s a good effort for them and us, but we are still waiting for the perfect point of sales for open source cyber cafe.

Others POS system such as OpenbravoERP, OpenbravoPOS, OpenERP are good software makers but still the softwares wasn’t meant for cyber cafe, internet cafe or gaming center.

Why is this happen? I don’t know, or maybe they think that running cyber cafe and gaming center business using an open source product couldn’t help the progress to expanding the influences. Instead of that, still some of others contributor was willing to spend their time, money and privacy to creating POS system such as ccl, mkahawa, gbilling and others, but still to software need more support on their development. Ubuntu or Canonical should supporting them in their software development(cyber cafe billing system).

So if you asked me what is the perfect POS system for open source cyber cafe should it looks like? If you look to the Cafesuite.net features then we might get some point how it should be. And if we takes their features to suggest what kind of billing system we really need for cyber cafe cafe then it’s could be just like below:

Security

It should provides many levels of security, ensuring that your business is always under control.

Workstation lock

Unused workstations can be securely locked so that no one can use them without proper authorization from the operator.

Operator profiles

You can create many profiles for your employees with different access rights. Not every one should be able to change crucial options or pricing schemes.

Encrypted data files

All databases used by CafeSuite are encrypted which ensures they can’t be tampered with by unouthorized individuals.

Backups

It’s possible to create backups of data files automatically evey given period of time. Your data will be secure even when your system crashes.

Ease of use

The user interface is clean and feels very natural even to begginers. The integrated help system will guide you in case of any problems.

Customer accounts

It’s should makes it really easy to manage large database of customer accounts. You can create different types of accounts for your customers — time accounts, cash accounts, debt accounts and unlimited accounts. You can assign beneficial charging rates to customer accounts to reward devoted customers.

Customers will be able to log on by themselves using their account ID and password. It’s also possible to create smart, magnetic or barcode cards for your customers, so that a simple scan of their card will log them on.

Reservations

It should provides unique graphical workstation reservation system. Simply select a time period on the workstation chart to create the reservation.

In case of a very big traffic, you’ll appreciate the Waiting queue function, allowing you to manage the waiting list.

Reports and statistics

The software provides you with a range of reports and statistics summarizing your business performance. Starting with very general reports, you can even get a list of all operations performed by your employees minute by minute.

Flexible charging rates

Real strength of the software lies in the flexible charging rates system. You can configure many schemes of pricing, including periodical discounts.

You can assign different charging rates to computer groups, beneficial pricing can be used with customer accounts. You can even create traffic discounts that adjust prices depending on the number of free computers in your cafe.

Support for external devices

You can use barcode scanner, magnetic card or smartcard reader to logon users with accounts and sell products. the software also supports receipt printers for printing receipts and account tickets.

Integration with Printer

The software integrates with Printer allowing you to keep control over your printers. Once a customer prints some pages, the software will notify the operator about that and calculate the charge automatically.

For your information, I’ve waiting the Cafesuite for linux, they said to running the software on linux since 2006 but until now there is nothing at all.

For me I would like to add some features to the above, it should supports diskless terminal client, for now I’ve tested CCL to be able to lock down diskless client. I think I should makes an article or tutorial about it.

Post installation

After a successful installation and boot to the newly installed Ubuntu Lucid with out problem, now it’s time for the post-installation. You might consider to create a user if you want, login as root with your previous password:

Step 1. You will need to edit your hosts file

If you have any question, do not hasitate to post it on our comment form.

Before I go on, a bit of a disclaimer: Following the instructions below may not provide you with results that fit your particular needs. If you have specific and detailed requirements, see the DRBL documentation. If you would like to hire LightCube Solutions to provide assistance in setting up a Clonezilla solution for your organization, send an email to info@lightcubesolutions.com.

The Steps

1. Install Linux

You’ll need a Linux machine to run your Clonezilla services. These instructions were successfully tested on Ubuntu 9.04 and 9.10 and Debian 5. DRBL will also run on Fedora.

2. Install DRBL

First off, open up a Terminal. In Ubuntu and Debian, this is located in ‘Applications -> Accessories -> Terminal’. If you have sudo configured, you can change to super-user access by typing:

sudo -i

Otherwise, use the root password with the following:

su -

Next, add DRBL’s GPG key to your system:

wget http://drbl.sourceforge.net/GPG-KEY-DRBL 

apt-key add GPG-KEY-DRBL

Update your apt configuration so that you can install software from the DRBL guys:

cp /etc/apt/sources.list{,.bak}echo "deb http://drbl.sourceforge.net/drbl-core drbl stable" \  >> /etc/apt/sources.list

Finally, install DRBL:

apt-get update 

apt-get install drbl

3. Configure a Network Alias

DRBL requires that you have two network interfaces. We can get around this by adding a virtual interface:

cat >> /etc/network/interfaces << "EOF"auto eth0:1iface eth0:1 inet static   address 192.168.222.1   netmask 255.255.255.0EOFifup eth0:1

To verify that you have set up the alias properly, type:

ip addr show eth0 | grep eth0:1

You should see something like this:

inet 192.168.222.1/24 brd 192.168.222.255 scope global eth0:1

4. Configure Your New DRBL Server

Run the following two interactive commands (note that this will require an internet connection and may take some time):

/opt/drbl/sbin/drblsrv -i/opt/drbl/sbin/drblpush -i

Congratulations! That’s it, you have a DRBL/Clonezilla server ready to create and deploy custom images. All you need to do to start cloning is run:

/opt/drbl/sbin/dcs

Then, boot up your client machines using PXE. See, that wasn’t too painful…

If network manager does not solve the problem, the first step should be to see which driver your wireless card needs. Do a search for your card on Google and in the Ubuntu Forums to find out which driver you need. Many of the drivers are already included in Ubuntu, but some newer drivers may not be present.

Next, you need to find out if the driver is loaded. As an example, if you have an Intel Centrino and it uses the ipw2200 driver, run this command:

sudo lsmod | grep ipw2200

Replace ipw2200 with the relevant driver for your card. If you get some lines returned, the driver is loaded and working. If nothing is returned, your card is either not supported or the driver is not included in Ubuntu. You should refer to the Ubuntu Forums for further support.

With the card identified, you now need to get connected. The easiest way to do this is to select System -> Administration -> Networking. Inside this tool you should see an icon for your wireless card. Select it and click the Properties button. Add the name of the wireless network and a password if applicable. If you are using a normal password such as s3cr3tpass, select Plain (ASCII) from the Key type box. If you are entering the long numeric password, use the Hexedecimal option. If you don’t have a password on your wireless network, leave the Key type and WEP key boxes empty.

If you are automatically assigned an IP address, use the Configuration box to select DHCP. Otherwise, select Static IP Address, and enter the details of your network in the boxes.
For more information, see the Ubuntu wiki.

Using WPA
To use WPA, you need a supported card. Such cards are listed on the WPA Supplicant Web site. Common drivers that support WPA include ipw2200, ipw2100, and madwifi.

To use WPA (Wi-Fi Protected Access) with wireless cards in Ubuntu, the wpasupplicant package must be installed. After installing it, edit /etc/wpa_supplicant.conf. Networks are configured by adding network blocks to the configuration file. Each network block can also be assigned a priority so if both networks are seen, the higher priority network is chosen. Examples for common network configurations can be found in /usr/share/doc/wpasupplicant/examples/wpa_supplicant.conf.gz.

Some configurations require certificates that should be available from the network administrator. WPA Supplicant can also configure your wireless card to use unencrypted networks, as noted in the example file. After writing the file, edit /etc/default/wpasupplicant and change the ENABLED, DRIVER, and INTERFACE options. The DRIVER option should match the type of wireless device being used. Available drivers can be viewed by typing:

wpa_supplicant -help

To start the Supplicant run:

/etc/init.d/wpasupplicant start

Lastly, wpasupplicant should be added to STOP_SERVICES in /etc/default/ acpi-support to ensure it functions properly after a system suspend or hibernation.

To check if the connection is working, run:

sudo wpa_cli

This command gives information on the current connection along with scrolling logs to indicate the current status. By default wpa_cli must be run as root. Status will show what network the wireless card is currently connected to and parameters about the link. Scan causes the supplicant to look for a new access point while scan_results will display what access points are locally accessible to the machine. As soon as the supplicant authenticates, ifplugd should start the interface with ifup, and networking will be available shortly. If it seems that the supplicant is not working it may be that a different driver must be selected in the /etc/defaults/wpasupplicant configuration file. Also, some cards cannot operate in a mixed TKIP/CCMP (types of encryption) mode. If it appears the PTK listed in the log from wpa_cli is CCMP but that the GTK is TKIP, setting the pairwise and group entries of a network configuration block to TKIP may fix the issue.
