Computer Tips -Tech Info

Openvpn has been one of the tools of choice this week, so as I was tinkering on my ubuntu boxen…. I thought why don’t I install openvpn there as well for a little broader testing. So, I did, but was a bit disappointed to see that the version was not the most current. (Yes, they […]

This is a good quick reference for some command line linux commands…. pixelbeat.org – linux command line tips. Nice reference. (of course you can also make use of man/apropos and -h to find out more….)    Send article as PDF   

I found a peculiar problem while I was setting up an openvpn link the other day. The goal was a simple shared key setup and I started with the sample configuration and modified it a bit to fit the circumstances, I allowed the correct UDP port through the firewall (I think 1194 if I recall […]

I saw yesterday that Dell has a page advertising computers with NO preinstalled OS.

Most of my video clips are in mpg format…. so there are ways to get it converted… here’s one such suggestion…. ffmpeg […]

A long time ago I had found how easy it was to reject messages outright with Postfix that came from non-existent domains. You know… junk from asdflkjuasdlfkjh@imadethisupmyselfanditsnotregisteredanywhere.com Well, since the mailserver at THIS site runs sendmail I wanted to fix sendmail the same as my home server.
