Official mRcore4 RESTful API Documentation! :r: Why? I have created several RESTful API's simply because I wanted to learn how to develop webservices using PHP and REST. I sort of followed Twitters API URL style (http:dev.twitter.com/doc), if they can't do REST, no one can eh? Eventually I would like to create a native Android application for mRcore4 using these API's, and possibly experiment abstracting the database layer completely, making all queries through an API. It has already come in ha...

<p>This topic helps with two things. One is to upgrade an old Ubuntu release to a new release, and by old I mean one that is no longer supported. Keep in mind that if say 9.04 is unsupported, but 9.10 is still supported, you can simply do the <tt>do-release-update</tt>. This doc helps when both 9.04 and 9.10 and above are EOL (end of life). Second is to maintain the use of an old Ubuntu distro even after its repositories stop working. Basically if you don't install the LTS (Long Term Support) release of Ubuntu then your distro is only supported for about a year. After that year all your repositories (using apt-get) fail and cannot be found. <strong>This is because Ubuntu archives the old repositories to a different URL.</strong> You don't actually have to upgrade your old Ubuntu distro, and you can continue to use it and its repos, you just have to switch to the new repo URL's. See below.</p>

See When you get say, Windows XP setup in your VirtualBox virtual machine, you can easily forward ports from the Host OS, to the Guest OS. An example, I want to use the windows Remote Desktop to remote into my virtual XP installation. I open port 3389 on my router to point to my ubuntu desktop, then I forward that port into my guest OS.

Used for mounting a folder over SSH (Secure Shell File System). So I can map drives from a remote linux server. From http:www.linuxinsight.com/sshfs_secure_and_transparent_access_to_remote_filesystems.html apt-get install sshfs or yum install fuse-sshfs Finally, as sshfs is designed to be used by regular users (not under superuser privileges) you should add yourself (and possibly others) to the fuse system group. Something like this should do: usermod -a -G fuse You must logout and login again...

FreeNX (http:freenx.berlios.de/) is a Terminal Server for Unix & Linux, similar to windows remote desktop or linux 2xTerminalServer. It is based off the non-free NX (http:www.nomachine.com/index.php). FreeNX client is only for linux, but NX has free clients for windows (http:www.nomachine.com/download.php) http:www.drtek.ca/freenx-server-ubuntu-hardy Note, uses SSH, so uses that port in /etc/ssh/sshd_config also, in sshd_config, if you have the AllowUsers set, then must add nx ex: AllowUsers nx...

Overview of the nfs server options I choose See man exportfs and http:www.troubleshooters.com/linux/nfs.htm for NFS server option details. Also CentOS docs are great for NFS client/serve details http:www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html secure server must be started by root because it will use ports lower than 1024 rw enable read and write sync data must be fully synced to disk, this prevents corruption if a server crashes no_wdelay I use this because my nfs re...

<p>This document describes a small portion of iptables and how to setup a basic firewall using iptables. There are many huge books on iptables so I cannot go into any sort of detail here. If you want to create a more advanced firewall, then I suggest installing shorewall and reading the documentation <a class="urlLink" href="http://www.shorewall.net/Introduction.html" onclick="window.open(this.href, '_blank'); return false;">http://www.shorewall.net/Introduction.html</a> about setting it up.

See LXF 114 p48, 'Banish Your Daemons' Runlevels are defined levels in which a linux operating system can start. Daemons (or services) are scripts/programs that run in the background constantly (like apache or mysql are services that are always running) and are usually executed at startup by the defined runlevel. Runlevels are identified by a number from 0 - 6, but each linux distribution may use those numbers a bit differently. Basically a runlevel determines which daemons to execute at startu...
