My previous phone has stopped working: it won't answer calls. T-Mobile wouldn't let me keep my previous number, so the shiny new number is 1.805.264.7967.

    ServerName hostname        
    ProxyPass        / http://somewhere/ retry=1
    ProxyPassReverse / http://somewhere/        
    DocumentRoot     /                          
</VirtualHost>

Use netcat/telnet over SSL

telnet and netcat are fine networking tools, but they don't themselves handle SSL: but that's okay, because openssl will do it for them.

openssl s_client -connect site:port

Tunnel ports over SSH

Simple enough: with this any connections to (localport) on localhost are routed off to (remoteport) on (remotehost).

ssh -2 -N -f -l localport:localhost:remoteport remotehost

Use mod_rewrite to re-direct traffic from www.*

This is normally done for SEO. In most situations a site is example.org with an alias of www.example.org (or vice versa) : they're the same site with the same IP. Some people believe that it helps your SEO if one is directed to the other and so you only have one site.

RewriteCond %{HTTP_HOST} ^www.example.org$ [NC]
RewriteRule ^(.*)$ http://example.org$1 [L,R]
