I am tired of looking for a simple, functional server monitoring program. I have spent the last week or so trying to get a fully functional setup of Nagios, Cacti, Zabbix, or Icinga and almost all to no prevail. Why is there no EASY and SIMPLE monitoring program out there that is Open Source, customizable, AND functional?
So I finally decided to make the jump to virtualization. Sure the performance is 1-3% slower then running on raw hardware, but the features gained from this way outweigh the cons. Now I can do backups on the fly, snapshots, quickly move resources around machines, and its all free thanks to Proxmox! Proxmox is a Linux Debian based distro that utilizes a custom kernel with support for OpenVZ and KVM. I’l go more into depth on Proxmox later, but for now here is my situation.
Having trouble with getting FTP to work on a server with iptables? Is your server stalling out when trying to enter passv FTP mode? Well this here is the quick fix for that. Its one of those little things thats nice to keep documented.
Recently for a fun project, I decided to set up an automated shared web host to test my coding abilities. I decided to go with a simple name, similar to one of my other domains. I ended up with Chris Host It. Sure its cheesy and not very professional, but this is just a test project after all. The problem was the back end I went with didn’t secure PHP as well as I wanted it to by default, so I had to fix that up. So here is a quick guide on securing PHP when using Virtualmin.

If you are like me, you always want the latest technology. IPv6 is the next BIG step up for the internet. It is a replacement protocol for the current IPv4 addressing system that is currently close to depletion.
What does this mean? Well with IPv4 the max amount of addresses possible is 4,294,967,296. Problem is they have all been handed out to ISP’s and companies. This is where IPv6 comes in. the IPv4 format is xxx.xxx.xxx.xxx, where xxx = 0,9.
Well, with IPv6 the address format is xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx where xxxx= 0-9 and a-f. This means there are 340,282,366,920,938,463,463,374,607,431,770,000,000 possible IPv6 addresses! With ipv6, address depletion will be a thing of the past.
So to stay with the game, I decided to deploy IPv6 on my servers. The only issue with it though is that my ISP seems to only offer it through a tunnel, or a IPv6 6rd tunnel to be exact. So after spending awhile with trial and error, here is how I access charters IPv6 network.
