IPv6 and default routes

Friday, March 5th, 2010

Following on from my first tutorial, we have a box set up which has basic IPv6 connectivity. There's a firewall in place with a simple but sufficient configuration. And we can ping6 from this box to remote IPv6 destinations. All of this has, so far, made use only of one network interface (in ...

IPv6 – logging and shorewall6

Thursday, February 25th, 2010

Following on from my early success at get IPv6 running, I soon hit a significant issue: firewall logging. Now this need not be a "blocker" for everyone, but I take my firewall logging duties quite seriously...! shorewall IPv4 logging Currently I have IPv4 shorewall configured to log not using the standard syslog mechanism, ...

IPv6 at home – a guide to getting started

Wednesday, February 24th, 2010

With IPv6 slowly becoming more visible, it was time to get to grips with it. While absolutely not essential (yet!) it seemed like a fun idea: my ADSL provider offers native IPv6 in parallel with IPv4, and my hosting provider is running an IPv6 beta. So I can do native ...

Bit torrent web clients

Monday, October 12th, 2009

As detailed in previous posts, I have a server at home which I use to download and seed torrents (and, before you ask, yes most of the torrent are indeed legal!!) The torrent-side of this server needs to be remotely accessible and manageable to me from a number of places, ...

Sockstress mitigation on Linux using Shorewall

Wednesday, September 16th, 2009

This week's hot security issue in the networking world is sockstress. Nasty little vulnerability, found in all known TCP implementations. Given the right circumstances (read up on it) it allows a very neat DoS attack to be mounted on a large destination with minimal attacking resource. And the really elegant part ...

Chrome really is nearly there!

Thursday, September 3rd, 2009

Yesterday I realised Chrome is going to be successful. Chrome is Google's web browser. It first appeared just over a year ago. For much of that period I've been pretty lukewarm about it. Thought it was more of a symbolic gesture than a serious attempt at muscling in on the browser ...

lighttpd

Wednesday, July 22nd, 2009

This site now runs on lighttpd! Apache2 was used previously. It' a fine web-server, but lighttpd is so much, er, lighter. About 30% lower memory consumption for the same performance. Also, as a side benefit, the config is simpler too. It does, for me at least, everything Apache2 can do: Multiple virtual ...

Google versus… anyone

Monday, June 15th, 2009

Recently Microsoft launched another attempt to dethrone Google as the search-engine kings of the Internet. Welcome to Bing. Go on, give it a try. You know, it's actually not bad. In fact it's quite good. Or at least not too far off as good as a search engine can be. ...

QuadKonsole on KDE4

Wednesday, November 5th, 2008

Under KDE 3 I've made major use of the wonderful quadkonsole, from Simon Perreault. It's a lovely thing, allowing you to embed 4 (by default, other permutations possible) konsoles in a single window, with them all resizing together. Kinda hard to explain, but very useful in some situations. KDE 4 comes ...

VIA – Hot stuff!

Sunday, August 31st, 2008

A while back I wrote a few notes on building a small home server box. Specifically that I had chosen this neat Morex case and this VIA EK Corefusion motherboard.Here in southern Europe the summer has been in full swing, and it got hotter by the day. A few weekends ...
