GNU screen comes with it's own copy & paste system that can be extremely handy when you are limited to a console: Control-o [ enters the region select mode, then Control-O ] will paste it again.

If you have the key, certificate, and intermediary certificate for an SSL site but your software only takes a PEM file, you can create it easily:

cat key crt intermediary >> pem

To strip a password from an SSL key with openssl, just do

openssl rsa -in key-file-with-pass -out key-file-without-pass

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.

<VirtualHost ip:80>
    ServerName hostname        
    ProxyPass        / http://somewhere/ retry=1
    ProxyPassReverse / http://somewhere/        
    DocumentRoot     /                          
</VirtualHost>

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

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

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]
