Joomla

Joomla is a content Management System and Web Application Framework. It was forked off from Mambo. More on http://www.joomla.org To install, extract the files out to a directory. Symlink it to a directory under where Apache runs, then bring that up in a web browser. It will check to see if everything is kosher in order to run. You might have to set permissions on files/directories.

SSH

Securely shell into another machine. You can use it to tunnel another protocol through it, and use it securely. For example, you can VNC into a machine, but the traffic is now encrypted because you are tunneling VNC through ssh. An example ssh config file put in .ssh:

Host nickname
 Compression yes
 ForwardX11 Yes
 Hostname nickname.somenetwork.net
 IdentityFile /users/timw/.ssh/id_rsa_somenetwork
 LocalForward 8300 gwmessenger.server.somenetwork.local:8300
 LocalForward 3389 rdphost.somenetwork.local:3389
 LocalForward 8000 wiki.somenetwork.local:80
 LocalForward 9090 192.168.7.195:80
 LocalForward 9091 192.168.7.212:80
 PasswordAuthentication no
 Protocol 2
 User skippy

Instead of doing ssh –L3389:rdpserver.remotenet.net:3389 ssh.server.remote.net, you can do ssh nickname, plus you have the other forwarded ports too. You can tunnel to squid over it, so all of your network traffic is encrypted, because it is going through tunnel.

RSS Readers

liferea stands for LInux FEed REader You can put several feeds into a folder, and set it to open child links, and it will show those feeds. That way you don't have to go into the child links to get the feeds. More at http://liferea.sourceforge.net/.

Other readers of note: RSS Owl (Java based), Straw, Akregator.

Misc info

There's a new speed test web site. It is http://speedtest.net. The parent of this site is http://ookla.com

On some newer distros, web stuff is put in /srv/www instead of /var/www.
