After yesterday’s post on IPv6 Networking in the house, I realized that all machines internally had publically facing IPv6 addresses! I started to panic, then went looking online, and found the following script:

This script, when run on your RouterOS board, will allow Established and Related connections, allow outgoing connections, and drop anything incoming that has not been requested… so, now everything inside the network should be more secured… I am new to this IPv6 stuff, so I am still learning… but, i am getting there…

In house, I have been using Microsoft TMG 2010 Server for a while now. I use it as a firewall for some of the machines on the network, and also as a proxy for most, if not all, machines. When acting as a Firewall, all traffic flows though the machine, be it HTTP/HTTPS, SMTP/POP3/IMAP, or anything for that matter. You can also lock down ports on the box, which is a feature of most firewalls, but i like TMG due to its relitive ease of use…

In my previous post on WANProxy, i did not really go into detail about what it actually was. The direct quote from their site is WANProxy is a free, portable TCP proxy which makes TCP connections send less data, which improves TCP performance and throughput over lossy links, slow links and long links. This is just what you need to improve performance over satellite, wireless and WAN links. This is something that has interested me for a while, so i have been looking into it, and so far so good. In my last post i mentioned i was proxying Squid traffic, in todays post, i still am, but with some tweaks.

As part of my new task to make my files safer and backups faster, and, well, cheap, I am looking into ZFS for my storage needs. My needs are as follows:

• Allow me to store lots of different types of data (Photos, Videos, Music, VMs) in different formats (RAW and JPG photos, MP4, AVI and DivX Videos, with DVD and BluRay rips also a posibility, MP3 music and VHD files from HyperV, inclduing ISOs and Snapshots). I also need to store different file systems using iSCSI (Mac and Windows clients will be mounting the storage).
• must be safe. DO NOT LOSE DATA!
• must be somewhat fast. I have VHDs weighing in at 100Gb… my photo collection is 600Gb. If i need to move or copy files to the storage system, it must be fast.

So, ZFS offers all these features. I can export a file share as iSCSI, NFS, SMB, etc. All works well. But the replication stuff is the interesting part…

[UPDATED] someone asked in the comments if there was an binary build for this file. there is now! http://handbrakecluster.codeplex.com now hosts the code and binaries, and will soon have help files and documentation.

A few days back, i wrote a post titled Powershell + Handbrake + AppleTV + iTunes = Automatic TV. ish. In it i included a block of Powershell code to bulk convert TV shows from whatever format you had them in to a M4V format for the AppleTV. Well, as they say “If necessity is the mother of all invension, lazyness must be the father”. I have a lot of shows i wanted converted to the AppleTV, so i built something. Its called HandBrake Cluster and is written in .NET 4.5, uses MSMQ and Handbrake to do the processing. The workflow is as follows:

I am a UPC Ireland customer, and have 2 cable modems into the house, both Cisco EPC3925s. These are not exactly great modems for power users, but are grand for normal use. Me, however, being a poweruser wanted something a little more, how should I put it, powerful.

A couple of months back, a tutorial was posted on Boards.ie which showed you How to enable “bridging” on your UPC modem. When i say “Bridging”, they used DMZ, turned off firewalls, static IPs internally, turned off WiFi and DHCP, etc. It worked, quite well actually, but was “odd”. Today, however, there is a new tutorial Enabling REAL bridging on a Cisco EPC3925. I have tried this, and so far, it works! now just to set my router to work correctly, and update my IPs if they change.

I have an AppleTV in the house (3, actually) and I am very happy with its ease of use, size and cost. You can’t argue with the small price!

I also have a lot of content that works great with the AppleTV in iTunes, but I have content which does not work so great with the AppleTV. So, I needed to find a way to convert files quickly and easily. that’s where PowerShell and Handbrake come in.

My main machine at home, known as “The GodBox” is a Dual Processor, Quad Core Xeon 5520 with 60Gb RAM, 2 300Gb 10,000 RPM Western Digital Velociraptor in RAID 0 for boot, 4X1Tb 7200RPM drives for storage, 2 more 300Gb 10,000 RPM drives for “scratch disk” and a couple high(ish) end graphics cards with 3 monitors plugged in. Hence the name, GodBox!

Anyway, The Raspberry Pi, on the other hand, has a 700Mhz processor, 256Mb RAM and not much else. So, if you need to write code for your Pi, and you don’t want to wait a long time to compile, check out this tutorial on how to build a cross compiler for your raspberry pi which will allow you to build your apps on a different machine. I have a college project which the Raspberry Pi will be used for, and i am thinking this will be how i build code.

I have been very interested in VOIP stuff for the last while now, and finally started looking at implementing it in the house. Here are some links which may be useful. I will do a full post soon.

• Asterisk 1.8 with chan_mobile on Centos 6: chan_mobile allows you to use a Bluetooth phone to make calls with Asterisk
• Use an old Mobile Phone as a GMS Gateway in asterisk: again, similar to above, but with Ubuntu.
• 3CX: my current choice in VOIP software.

The main VOIP hardware I use is:
