Logitech G15

Xoke: g15 daemon now in repos so edited to say that

'''The information on this page is taken from [https://help.ubuntu.com/community/LogitechG15] and was copied ver batim to this page. Text formatting was changed to be wiki compatible.'''

'''This content is quite old and may not be applicable to current versions of Ubuntu.''' (please remove this note if the page is updated)

= Introduction =

This will walk you through the process of installing and configuring your Logitech G15 keyboard in Ubuntu. After doing this, you will be able to use the LCD display and all of the special keys will work just like normal keys that you can bind shortcuts to. To do this, you will need to do three things: download and install drivers so that Ubuntu recognizes the LCD and extra keys, add symbols to X so that the extra keys exist in X, and bind the extra keys on the G15 to the symbols you created.

= Installing G15 drivers with G15tools =

*If you are running a newer version of Ubuntu (Intrepid+) G15Daemon is in the repos so you can just sudo apt-get install g15daemon and skip to the modprobe uinput further down. Otherwise continue below*

First, install the required libraries: libusb and libdaemon, and if not allready installed the build-essentials package.
sudo apt-get install libusb-dev libdaemon-dev build-essential

Download libg15, G15Composer, and libG15Render from http://g15tools.sourceforge.net/, and http://sourceforge.net/projects/g15daemon|G15Daemon. Extract the packages to their own directory, change to that directory, compile and install the files. You must install libg15 and libG15Render first. In each directory, run the following to compile and install the files. To do this, run the following in the directory that you put the files you downloaded:

tar -xjvf <file>
cd <directory that it extracted into>
./configure
make
sudo make install

''If you see an error while running <tt>./configure</tt>, make a note of what it said was missing before it failed. This is most likely the name of a program or library that you need to install. You can open up the Synaptic Package Manager in the System->Administration menu and search for that file. You will most likely want to install the one that ends in -dev.''

Repeat this for every package that you want to install, making sure to go in the order specified above. Once you have done this, it is safe to delete the .tar.bz2 files as well as the directories you made; the programs have been installed and you do not need the source anymore.

Now load the uinput module and set it to load when you start the computer:

sudo modprobe uinput

Run <tt>gksudo gedit /etc/modules</tt> and add <tt>uinput</tt> to the list.

After you've done this, run <tt>sudo g15daemon</tt>. If you see a clock appear on the LCD screen, it is working properly. If not, refer to the Troubleshooting section below. To set g15daemon to run automatically at startup, edit the sudoers file by running the following:
sudo visudo

Add the following line to the bottom of the file -
ALL ALL= NOPASSWD: /usr/sbin/g15daemon
'''Warning:''' If visudo complains about syntax errors when you exit the program, do '''not''' ignore them! Go back and look at the file and see what went wrong. If you mess up the sudoers file you might not be able to run sudo at all, which you'll need a LiveCD to fix.

After you have done this, add g15daemon to your session by going to menus System -> Preferences -> Sessions, selecting New under the Startup Programs tab, and adding one with the name ''G15Daemon'' and the command ''sudo /usr/sbin/g15daemon''.

== Troubleshooting ==

If you get an error that says:
g15daemon: error while loading shared libraries: libg15.so.1: cannot open shared object file: No such file or directory

You need to run <tt>gksudo gedit /etc/ld.so.conf</tt> and add <tt>/usr/local/lib</tt> at the top of the file. Then run
sudo ldconfig

That should fix the problem, try running the daemon again.

= Adding key symbols to X =
It is possible to use your newly accessible G15 keys in Ubuntu by going to:

System>Preferences>Keyboard>Layouts

and selecting "Logitech G15 extra keys via G15daemon" under "keyboard model".

An alternative method follows:
To add the symbols required to represent the special keys, run <tt>gksudo gedit /usr/share/X11/XKeysymDB</tt> and add the following lines after the comment at the beginning -

<tt>
G1 :15000001
G2 :15000002
G3 :15000003
G4 :15000004
G5 :15000005
G6 :15000006
G7 :15000007
G8 :15000008
G9 :15000009
G10 :15000010
G11 :15000011
G12 :15000012
G13 :15000013
G14 :15000014
G15 :15000015
G16 :15000016
G17 :15000017
G18 :15000018
M1 :15000019
M2 :1500001A
M3 :1500001B
LCD0 :1500001D
LCD1 :1500001E
LCD2 :1500001F
LCD3 :15000020
LCD4 :15000021
MR :15000022
</tt>
''Request - Can someone who is more experienced with this file tell me if these hex codes are good? I don't know if there's a list of reserved codes somewhere.''

Save this file, and move on to the next section. If you upgrade your X server, you may have to re-insert these codes.

= Binding the keys to the symbols =

To use your newly created symbols, you'll need to create an .Xmodmap file in your home directory (or edit the one you already have). If you do not have one, run ''xmodmap -pke > .Xmodmap'' in your home directory (using a terminal). Open this file (run <tt>gedit ~/.Xmodmap</tt>) and add or change the following lines (you can determine keycodes running the "xev" application at a terminal):
<tt>
keycode 93 = M2
keycode 129 = G5
keycode 130 = G6
keycode 131 = M3
keycode 132 = LCD0
keycode 133 = G12
keycode 136 = G10
keycode 137 = G15
keycode 138 = G16
keycode 143 = G12
keycode 146 = G10
keycode 152 = G2
keycode 170 = LCD1
keycode 177 = G1
keycode 182 = G17
keycode 183 = G18
keycode 184 = M1
keycode 190 = G3
keycode 205 = LCD4
keycode 208 = G4
keycode 209 = G8
keycode 210 = G9
keycode 219 = LCD2
keycode 220 = G11
keycode 231 = G7
keycode 246 = G13
keycode 247 = MR
keycode 249 = LCD3
keycode 251 = G14
</tt>

Now log out and back in, and your extra keys will work just like any other. You may get a message when you log in asking if you want to load .Xmodmap. Add .Xmodmap to the load list and check the box that says 'Do not warn again'. Congrats!

Bandwidth

2007-11-06T16:17:40Z

Xoke: Possibly the worst analogy anywhere, but might be stupid enough for people to remember :)

[[ Bandwidth | Bandwidth ]] is basically how much data you can send at once. If you imagine your wires are roads going somewhere and the data you are sending are a marching band walking down that road, the ''width'' of the road affects how big a band you can send. So the ''bandwidth'' is the width of the band you can send. The wider the road, the wider the band, or the more data you can send. If the road (or connection) is twice as wide (or fast) then you can have a band twice as wide (twice the data) in the same time. The band (or data) always travels at the same speed.

Bandwidth can be measured in various ways, but is always a certain number of bits per second. This is not bytes per second but is similar. Modems are currently measured in kilobits per second and DSL and cable can be kilobits per second or megabits per second. The maximum download speed you generally get is somewhere around 1/5 of the rated speed. So if you are running a 35.5K modem you will find you won't get downloads faster then 7K, although this depends on where you are downloading from as it may be even less then that.

Uname

2007-08-20T20:09:03Z

Xoke:

'''uname''' is a command which prints [[system information]] like the kernel name. This can be very useful if you're trying to install or make a program and it requires headers for your kernal or similar. Instead of having to keep searching for your specific ones, if you have apt-get or similar program you can pass the output from uname to install whatever files are required for your architecture and kernel.

[http://man.linuxquestions.org/?query=uname&section=0&type=2 man page]

Master

2007-07-11T17:34:43Z

Xoke: Created page, linked to 'slave' page I just wrote also

'''Master''' is one of two main settings for a hard disk. The other being [[Slave]]. See that article for more information on ''master'' and ''slave'' settings.

IDE master/slave

2007-07-11T17:31:57Z

Xoke: Created page, wrote some drivel that people will rip to bits probably ;)

'''Slave''' is one of two main settings for a hard disk. The other being [[Master]]. If you are building a computer you can set hard drives to be ''master'', ''slave'' plus a few others depending on hard drive type (like ''cable select''). These are selected by putting a jumper in certain positions (or sometimes removing the jumper). This depends on the hard drive though, but is normally written near the jumpers on the back of the hard drive.

If you have a single IDE cable, with two hard drives on it one must be set to master and one to slave. The master is the first or primary hard drive and the slave is the second or secondary. The reason they ''primary'' and ''secondary'' are not used is that most computers have two IDE cables for hard drives and they are known as the primary and secondary. So if you have four hard drives then you have a primary master, primary slave, secondary master and secondary slave.

Originally you could only boot off the primary master, however nowadays you can boot off almost any hard drive (although the boot loader still needs to be on the primary master). Also, when CD burners first came out they were very picky about where they had to do. You had to put them on the 'other' IDE cable from where you were copying the CD from. So if you were copying CD to CD you had to set them up as primary slave (primary master being the boot HD) and secondary master (if you had no other hard drive). Nowadays as computers are much faster this is no longer an issue.

If you have two hard drives which are used more then the CD drives, then you can gain some speed by putting them as primary master and secondary slave because then each IDE cable can run all the information between each hard drive and the rest of the computer. If they are both on the same IDE cable then it's speed is split between the two drives. This of course depends on exactly what you are doing on both hard drives, but if you are setting up a PC and put the OS on primary master and the swap file or user file area on secondary master that can increase speed (slightly).

The exact setup of primary master, primary slave, secondary master and secondary slave can be a contentious issue though sometimes with many different views on how to do it. This is a lot less of an issue now with faster computers though. Simply put, depending on your computer you may want a different setup for your masters and slaves.

Firefox

2007-05-24T15:39:29Z

Xoke: /* Current version */

'''Mozilla Firefox''' (once known as "[[Firebird]]") is a [[cross-platform]], [[open source]], free [[web browser]] available for [[Windows]], [[Mac OS X]], [[Linux]] and other operating systems. Unlike the [[Mozilla]] Suite, which includes a [[chat]] client, [[mail]] functions, and web page editor, Firefox is just a browser, and is considerably faster than Mozilla.

Since the introduction of version one of Firefox in the fall of 2004, Firefox is considered a viable alternative to Microsoft's browser, [[Internet Explorer]]. Thanks to features such as pop-up blocking, tabbed browsing, security features, Firefox has gained a substantial market share and the expense of Internet Explorer.

==History==
Firefox was originally known as Phoenix but was later renamed to Firebird and then, in February 2004, to Firefox, because of confusion with [[FireBirdSQL]].

==Current version==
The latest Firefox version is Firefox 2.0.0.3 (as of May 2007). For more information about Firefox, and to download it, see the [http://www.mozilla.com/firefox/ Firefox homepage].

==Distribution specific information==

===Debian===
[[Debian]] firefox packages for testing/sarge and unstable/sid users are available in the standard Debian repository, get them with <tt>[[apt-get]] install mozilla-firefox</tt>. Debian stable/woody users can get a backported version [http://www.backports.org here]. A list of available plugins and locales packages can be found with <tt>[[apt-cache]] search --names-only mozilla-firefox</tt>

===Gentoo===
[[Gentoo]] users can install Firefox from a root prompt using [[emerge]], ie:

:<tt># emerge mozilla-firefox</tt>

or

:<tt># emerge mozilla-firefox-bin</tt>

(to get the official binary build installed).

==From the new Linux Installer==
Download the latest Linux installer from
[http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ ftp.mozilla.org].
''(Note: The installer ends in '-installer.tar.gz')''

Extract it to a temporary directory, and go into the 'firefox-installer' directory. Now you must decide whether you want to install firefox system-wide, so that all computer users can use it, or whether to just install it for yourself. When you have finished the install you may delete the 'firefox-installer' directory.

===Installing Firefox for Personal Use===

Run the script called 'firefox-installer', in the firefox-installer directory. (If you are using a gui tool, you should be able to simply click on it) Click next until you are given a choice where to install firefox. You will probably want to install it somewhere like '/home/yourname/programs/firefox'. From there the install should be simple. To run firefox you must either run '/home/yourname/*/firefox/firefox', or make a shortcut to it (varies depending on your desktop environment).

===Installing Firefox System-Wide===

Open a terminal. Type in 'su' to login as the super-user. Use 'cd' to change to the directory where you extracted the firefox-installer (eg. <tt>cd /home/yourname/firefox-installer</tt>). then type in <tt>./firefox-installer</tt>. Click next until you are given a choice where to install firefox. To keep in line with linux standards, you will want to install it to '/opt/firefox'. From there the install should be simple. Once it is completed, go back to your terminal, and while still logged in as root, type in <tt>ln -s /opt/firefox/firefox /usr/local/bin/firefox</tt> (assuming you installed to /opt/firefox). This will mean any user can run firefox by simply typing in <tt>firefox</tt>, just like they were running any other program.

==From Their Binaries==
Mozilla makes nightly binaries available at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/,
or get the latest release from
http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

Untar it somewhere in your home directory with "tar -xvzf whatever.tar.gz"
you will have to run it with ./firefox from that directory, or you can create a [[shortcut]] to it.

if you want browser plugins to work, symlink your main plugin directory contents to your new plugins directory. You will want to keep the existing libnullplugin, so rename it before doing so, and rename it back. Main plugin directories are often in /opt/mozilla or in /usr/lib/mozilla-version or similar.

== Firefox tips==
*Type "about:config" in your location bar to get a complete and editable list of Firefox's preferences.
**filter by:
***'''error''' and set the resulting setting to be true for error messages that show in the browser page instead of a pop up
***'''dom''', then set all of the dom.disable options to true if you want to have control over the content in the web browser (these should work with all sites, no site should depend on using these features, they are all [[security hazard]]s when off)
***'''mouse''' set middlemouse.contentLoadURL to false, that way middle clickin on a tab will close it
***'''autoscroll''', set it to true, and you'll middle mouse button wont' paste personal information to a search engine everytime you accidentally click it, also does the autoscroll feature, which is an ergonmic feature, that will save you from finger strain. (IE on windows has this, and firefox on windows has it on by default)

*Creating a shortcut under KDE
**If you use KDE and would like a shortcut to firefox to appear under the "K" menu you can perform the following steps.
***Right-click the "K" menu then select "Menu Editor". A "KDE Menu Editor" window appears.
***Navigate to the location where you would like the shortcut to appear (ex: Internet>Web Browser). [Note: the default menu "folders" that appear in your K menu will differ depending on your linux distribution.] With the appropriate folder selected, right-click then select "New Item". Enter an appropriate name (eg: Firefox v1.0x) in the "New Item - KDE Menu Editor" dialog box then click OK.
***With the new Firefox 1.0x menu item selected place your cursor in the Command field, then type in the proper path to the firefox executable. In the example provided above, this would be /opt/firefox/firefox
***Select the proper icon for the FireFox shortcut by clicking on the Select Icon button (located just to the right of the "Name" field). In the Select Icon dialog box, select the Other Icons radio button, then browse to your /opt/firefox/icons directory and select the firefox .png file, click OK.
***In the KDE Menu Editor dialog box, select FILE>SAVE, then select FILE>QUIT. Enjoy!

===Adblock extension===
[http://adblock.mozdev.org/ Adblock] (''adblock.mozdev.org'') is an extension to Firefox that does exactly what you would expect it to do: it blocks advertisement banners, as well as flash animations and other similar nuisances.

To install it, follow [https://addons.update.mozilla.org/extensions/moreinfo.php?application=firefox&version=1.0&os=nt&id=10 this link] and click on the link that says "Install Now." If you have never installed an extenion before, you will most likely have to add <tt>update.mozilla.org</tt> to the list of sites that may install software onto your computer. To do this, click the button that says "Edit Options" and click the button labeled "Allow." Once the extension is done being downloaded and installed, restart Firefox to complete the installation.

In order to block the vast majority of internet advertisements, go to [http://www.pierceive.com/ pierceive.com] and follow the links to download a set of filters called Filterset.G. Right click on the latest version of the file and choose "Save link as" and save it to a suitable location on your hard drive. To install these filters, click on <u>T</u>ools, point to <u>A</u>dblock, and then click Preferences. Click on the button labeled "Adblock Options" and click "Import filters." Navigate to the location in which you saved the filter file and click "Open." This imports the filters.

There are some recommended settings for Adblock that will assist in enhancing your browsing experience. To active them, open the preferences panel (see above) and click on "Adblock Options." The option labeled "Obj-Tags" should be selected already. In addition to that, select the following three options, as well as "Keep List Sorted."

If an advertisement appears on a web site that is not blocked, it is very easy to block it for visits. Right click on the image and click the bottom option, "Adblock Image." A dialogue should open with the image's URL. You can click "OK" to block just that image. However, if you notice a pattern, for instance <tt>http://www.example.com/images/ads/banner1.gif</tt>, it may be beneficial to block <tt>http://www.example.com/images/ads/*</tt>.

Unfortunately, wildcard blocks like that can occasionally lead to accidental blocking of unintended images. For that reason, Adblock allows you to remove filters you've set previously. In our above example, if by blocking things using the filter <tt>http://www.example.com/images/ads/*</tt> made images disappear, you would want to delete that filter. To do so, open the Adblock Preferences (see above) and locate the filter on the list. It should be alphabetical, so locating it should not be difficult. Once you have found it, right click on it and either choose "Edit Filter" to change it and possibly correct it, or "Delete" to remove it outright.

== Firefox troubleshooting==
'''Profile in use after power off'''
Firefox uses a file called lock in its profile to determine if the profile is in use. If Firefox is running during a power failure, this file is still there, and Firefox will fail with profile in use message. To fix it, find the lock file and delete it.

Running as user, execute

<tt>user@linuxbox / $ cd ; find .mozilla -name lock -exec rm -f {} \;</tt>

The above command will first change your current working directory to your own home directory (in this case, /home/user), then it will find all files called lock that are located in your .mozilla directory and any other subdirectory below it, and delete them forcefully. Or you can do the same thing with a file manager such as Konqueror.

Now firefox should work again.

Talk:Squid.conf

Xoke:

OK so my first new page (be gentle!)

This is how I have set squid up on my machine based on reading the help files and various other help websites. It should be fairly good but if anyone has any suggestions on how to improve obviously please do - want to see how well I did. It should be fairly anonymous and secure... in theory. Things like lying with the user agent I'm not sure if it really helps, but it seems like a good idea to me.
--[[User:Xoke|Xoke]] 14:40, April 20, 2007 (EDT)

good but too much for experts - e.g. how do I start squid ? --[[User:ThorstenStaerk|ThorstenStaerk]] 15:45, April 20, 2007 (EDT)

Depends on what distro you're using - debian based ones should start it when you apt-get it. You may have to start it manually from something like:
/etc/init.d/squid start
But again not sure - depends on your distro.
Oh and thanks for putting them as a quote :) I had a text file with the changes I'd done and pretty much copied and pasted it into this wiki.

Hi, I'm Xoke. I started playing around with Mandrake Linux years ago (v6?) but never got really into it. Tried Ubuntu in the beginning of 2006 and have been using Linux almost exclusively since then (apart from playing some games under Windows). I'm still trying to get my Wife into Linux but unfortunately she's fairly against it. She uses windows because 'it just works' then sits there and complains about how slow her computer is running!

Also recently I must mention my friends recent passing. Yes he's gone (back) to the dark side of windows :( He was my first linux convertee and I lost him. Strangely enough because he likes playing planeshift and it crashed more on linux then on windows for him! He did really like linux though so I hope to bring him back into the fold :P

Xoke: New page: OK so my first new page (be gentle!) This is how I have set squid up on my machine based on reading the help files and various other help websites. It should be fairly good but if anyone...

Squid.conf

2007-04-20T18:38:23Z

Xoke: New page with my settings. Please change if you can do better :)

To set up squid to block ads, cookies, referer (sic) to get a lot more privacy when browsing you can do the following:

* Install squid

Note: You may want to do this all as root to stop users editing these files. The following commands are done via a command shell. Also this setup is for a single user running squid on their local machine. To set up squid for more users a few lines will have to be amended (for example blocking access from all machine).

* cd /etc/squid

Make some files we need
* touch blacklist
This is going to be any sites we want to block
* touch cookie_allow
Sites we want cookies on (like linuxquestions.org!) so you can log on.
* touch referer_allow
Site that require the referer. It is spelt referrer however the original spec typod it as referer.
* touch user_agent_allow
Sites that require a real user agent (as opposed to the spoof one we are going to use)

Edit /etc/squid/squid.conf using your favourite editor. There are lots of things to change here in many places, so listed here are the lines to search for and the lines to add in afterwards. Bulleted lines in italic are the original lines, bulleted lines not in italic are lines to add. Unbulleted lines are explanations. We use linuxquestions.org always as an example so other websites don't get upset!

* ''# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS''
* acl blacklist dstdomain "/etc/squid/blacklist"
* http_access deny blacklist
This tells squid to block any matching domains listed in the file blacklist. If you want to block an entire website (linuxquestions.org say, although why you would want to block that!) you can simply edit the blacklist file and put:
.linuxquestions.org
which blocks www.linuxquestions.org, wiki.linuxquestions.org etc. Putting:
wiki.linuxquestions.org
would block just the wiki.

* ''#visible_hostname''
* visible_hostname proxy
This tells squid to tell everyone it is called 'proxy'. It defaults to your machine name which could potentially be a security risk.

* ''# forwarded_for on''
* forwarded_for off
This tells squid not to tell anyone it is a proxy. Depending on the setting you may not want to have this one.

* ''# By default, all headers are allowed (no anonymizing is''
* ''# performed).''
* ''#''
* ''#Default:''
* ''# none''
* header_access From deny all
* header_access Server deny all
* header_access WWW-Authenticate deny all
* header_access Link deny all
* header_access Cache-Control deny all
* header_access Proxy-Connection deny all
* header_access X-Cache deny all
* header_access X-Cache-Lookup deny all
* header_access Via deny all
* header_access Forwarded-For deny all
* header_access X-Forwarded-For deny all
* header_access Pragma deny all
* header_access Keep-Alive deny all
* acl referer_allow dstdomain "/etc/squid/referer_allow"
* header_access Referer allow referer_allow
* header_access Referer deny all
* acl cookie_allow dstdomain "/etc/squid/cookie_allow"
* header_access Cookie allow cookie_allow
* header_access Cookie deny all
* acl user_agent_allow dstdomain "/etc/squid/user_agent_allow"
* header_access User-Agent allow user_agent_allow
* header_access User-Agent deny all
These lines do lots of things. It blocks domains from reading the referer, cookies and user agent. It blocks the 'forwarded for' header lines (which again could be a potential security risk giving actual machine names / IPs). They also block connections to the squid proxy from all machines except local (see note at the beginning of this page).

''* #header_replace User-Agent''
* header_replace User-Agent Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; YPC 3.0.1; .NET CLR 1.1.4322; .NET CLR
This line tells websites that you are running IE7 on Windows XP. Some bad websites have been known to look at your user agent and try to use browser specific exploits, which should fail using this user agent.

* ''# TAG: deny_info''
(many more lines until end of section)
* ''# by specifying TCP_RESET.''
* deny_info http://localhost/blacklist.gif blacklist
This line changes any websites in the blacklist to become blacklist.gif. You can create the file as a small transparent gif file to replace any ad with. You will need to make this file yourself otherwise you will get a file not found error. If you don't want to replace the ads, you can skip adding this line however you will see 'access denied' instead of the ads.

Now save the squid.conf file. If you want to block almost all the ads on the internet you can download a hosts file (for example from [http://www.mvps.org/winhelp2002/hosts.htm]here) and save it. Unfortunately it is in the wrong format however running the file through:
sed 's/\#.*//' hosts.txt | sed 's/127.0.0.1 *//' | sed 's/localhost//' | sed -e '/^$/d' > blacklist

To pretty much sort file out. Might leave some blank lines at the front so edit blacklist to check. You can remove the hosts.txt file now if you wish. Copy the blacklist file into /etc/squid.

Edit /etc/squid/cookie_allow and dd in any sites you want to allow cookies, e.g.
.linuxquestions.org

Do the same with referer and user agent.

Restart squid using: squid -k reconfigure

Set browser to use squid port and check it all works!

Squid

2007-04-20T17:59:28Z

Xoke:

'''Squid''' is:

* a full-featured Web [[proxy]] cache
* designed to run on [[Unix]] systems
* free, open-source software
* the result of many contributions by unpaid (and paid) volunteers

In other words, squid can be set up to download and cache websites for you to save on your bandwidth. You can also change / block / redirect pages. For example you can get some pages to automatically pick the 'print' option, or block ads. This is all done via the [[squid.conf]] file found in /etc/squid.

Squid supports:

* proxying and caching of [[HTTP]], [[FTP]], and other [[URL]]'s
* proxying for [[SSL]]
* cache hierarchies
* ICP, HTCP, CARP, Cache Digests
* transparent caching
* WCCP (Squid v2.3 and above)
* extensive access controls
* filtering of unwanted web content with [[ufdbGuard]]
* HTTP server acceleration
* SNMP
* caching of [[DNS]] lookups

Blender

2007-03-01T07:30:40Z

Xoke:

'''Blender''' is a [[3D modeling]] application available for Linux, Windows, and Macintosh. It is a powerful, professional 3D environment, but it has a steep learning curve, and many sometimes obscure shortcut keys. It currently supports animation rendering, radiosity, particle systems, and [[OpenGL]] Realtime animation for some (but not all) platforms/OSs. Blender is an interesting program because it was originally a commercial, closed source program. The company that made it went bust, and the code was released as open source for a fee to the creditors. That fee was paid and so the once closed source program became open source.

Learning how to use Blender can be tough, but it's worth it. A good place to start is the Using Blender section of [http://www.blender3d.org Blender3d.org]. From the homepage, go to InfoCenter -> Using Blender.

Blender has a built-in python [[interpreter]] and [[API]] for 3D object manipulation. Along with the built-in script library, there are many community-created scripts and tutorials for creating your own scripts.

In 2006, an 'open' video made entirely by blender was released called [http://orange.blender.org/ Elephants Dream]. This was made under the Creative Commons license which allows anyone to use it to make their own movies as long as they say they used Elephants Dream.

Firewall distributions

2007-01-26T18:13:40Z

Xoke:

A '''firewall distribution''' is simply a [[distro]] whose primary function is to act as a [[firewall]]. A typical firewall distro might come on a bootable [[CD-ROM|cd-rom]] or [[floppy disk]], and enable you to transform a PC into a dedicated firewall appliance.

This usually costs a fraction of a similarly capable off-the-shelf firewall, especially if you already have an old computer. Running Linux, a [[80486|486]] with 16megs of [[RAM]], worth almost nothing, can outperform a dedicated firewall costing several thousand dollars. It will also be easier to configure if you are familiar with Linux and [[iptables]]/[[ipchains]].

==List of firewall distributions==

===Hard drive based===
*[[IPCop]]
*[[picofirewall]] (picofirewall is NOT a firewall distro)
*[[SmoothWall]]
*[[MonoWall]]

===CD based===
*[[Devil-Linux]]
*[[redWall]]

===Floppy based===
*[[FloppyFW]]
*[[Freesco]]
*[[LRP]]
*[[LEAF]]
*[[Coyote]]

===Commercial ===
*ClarkConnect - A hybrid of firewall and SOHO server (mail, fileshare, etc functions). There are paid, closed-source office and enterprise versions, and an open source, gratis version at clarkconnect.org. They all run linux. However, none of these are free (http://www.clarkconnect.com/about/eula.php).

Router

2007-01-26T17:50:56Z

Xoke:

A '''router''' is a networking device which operates at layer 3 of the [[OSI Model]]. Its purpose is to switch data packets between its various interfaces based upon the destination IP address of the packet.

Routers are intelligent devices and can make decisions about which route a packet can take through a network if there are multiple paths possible. The decision about which path to take is made from a link's cost which is calculated from the factors of bandwidth, [[hop count]], financial cost, load, delay and reliability.

Most Linux [[distributions]] come with routing support allowing your Linux machine to operate as a router if it has one or more [[NIC]] installed.

Many routers also provide a service known as [[NAT|Network Address Translation]] or NAT.

It should also be pointed out that from a security point of view, if you have a router, then every computer behind it is protected from attack from the other side (i.e. the internet). This doesn't protect you from someone sending you a trojan through email, if you run the attachment however, but it will protect you from worms running around on the internet. Linux of course does not have anything like the kind of problems with worms and trojans that windows has though.

Very cool info about yourself, Xoke. Glad you like Ubuntu. I've been using Linux since about 2002. I see you've been editing some pages; we all appreciate it. I hope to see you around here some more. Thx --[[User:Sepero|Sepero]] 05:28, January 26, 2007 (EST)

Well I figured it was time to help out the community. I just have to brush off my C coding books (at work we were a VB shop) and see what I can do to help code to help even more!

Just watch people remove my changes now - although most of the pages were created from scratch so unless they delete them there will now be a page there where before there was none :)

Setiathome

2007-01-26T07:24:23Z

Xoke:

From the website:

'''SETI@home''' is a scientific experiment that uses Internet-connected computers in the Search for Extra Terrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data. A command-line only version is available for Linux and other Unix based operating systems.

A similar, but more flexible, program is called BOINC. This allows you to analyze any data someone wishes to let you. There are a great number of projects out there requesting help, and you can select to run as many as you want (although only one at a time).
