Someone asked how to set this up quickly and easily… the idea being:
1) you have a host somewhere on the interwebs that’s accessible via SSH and runs a squid/proxy for you
2) you have a macintosh
3) you don’t normally do unix-y things
4) you’d like a command-line quick and easy setup to allow you to proxy your traffic (web/chat) through your ssh host and sqiud

So, after a period of time your GPG key will expire, if you want it to expire, that’s good news. If you happen to still be using it, not so good news. Simple un-expire instructions follow.

Postfix has a bunch of queues, and a bunch of stats through other packages, how about some simple shell things if you have multiple instances running?

I can never remember how to do this, I always have to try the 10 versions of perldoc help then resort to google searches… So, documentation in a common place seems like a nice idea.

GnuPG and PGP are public key encryption programs, they are nice and convenient and helpful at avoiding sending ‘important’ content in the clear in email (SMTP is plain-text you remember, right?) Often console-based email clients can be fussy to setup to use this software. Here’s a quick guide, stolen from someone else (Stolen-content).

Once you make your new kernel, how do you put it into use? 

Often when you start with an SSL certificate it has a passphrase, you may want to change that later. You may realize your webserver won’t start without entering a passphrase at the startup dialog. That’d be a bad thing for your webserver, eh? Really the problem isn’t with the certificate so much as the key, which is encrypted with a passphrase.

How many people have wanted to make an SSL certificate for one reason or another and didn’t want to pay the outrageous fees to someone to get a legittimate one, afterall if it’s just encryption you want why pay when openssl makes them free for you? Here’s how…

Ever had to move data around on a regular basis? Say to copy statistics and such from machine to machine to a central location without having some hokie psuedo user with funked up permissions? Have you the same problem as I do? Every single time you want to do this you have to google: “ssh forced command keys” and hope that link 3 doesn’t change on you? Fear not… documentation below!

Some simple statistics gathering for systems monitoring, graphicalized for your pleasure! Everyone likes graphics and they do help to make trends visible quickly. This short explanation should give some starting points and references on using Tobi Oetiker’s fine rrdtool to store and later display the data in question.
