A tip for Buffalo WYR-G54 owners

Monday, September 26th, 2005

The Buffalo WYR-G54 is a wireless router which eBuyer (probably others too) are selling really cheaply at the moment. Something many people (myself included) like to do with wireless networks is disable SSID broadcasts; this makes the network more difficult for people to detect unless they already know the SSID (no, security through obscurity is never the answer, but it helps).

In the manual there is a screenshot showing an “enable SSID broadcast” option. This option actually doesn’t exist either in the original firmware I got with my router or in the latest firmware. However, it is still possible to disable SSID broadcasts with a bit of effort:

  1. Use the web interface to save the router settings to a file
  2. Open the file (admcfg.cfg) and look for the ‘[533004:Broadcast SSID]‘ option (near the bottom)
  3. Simply change ‘yes’ to ‘no’
  4. Use the web interface to restore the settings from the file you just edited
  5. The router reboots and that’s it: no more SSID broadcast

Quite why Buffalo felt the need to remove the option from the web interface I can’t imagine…

While I’m moaning about Buffalo, I’ll also mention the fact that the web server on the device can’t cope with browsers that implement HTTP pipelining (this includes Mozilla & Firefox at least). While it basically works, pages take AGES to load, you end up with the server serving files other than the ones requested and you have to re-start the browser after you’ve done a form POST before the server will talk to you again. I dream of the day that people who only test their products with IE will get what’s coming to them…

But for £29.34 I guess I shouldn’t really complain too loudly…

Me, the kernel developer

Yep, I’ve just had not one but two patches accepted into the Linux kernel.

This all started when I bought a Nebula DigiTV-PCI DVB card which didn’t work under Linux. Looking back through the linux-dvb list archives I found an old patch someone had submitted to make it work. This patch didn’t get accepted because it needed fixing and cleaning up. So I took the patch, re-made it to apply to the current dvb-kernel CVS and fixed the problems. So no I didn’t actually add the support for the card myself, but I got it into the kernel. I still wouldn’t suggest anyone goes out and buys one of these though: not only are they overpriced, but they have some hardware issues which cause lots of people problems.
The other patch is to clean-up the particular file I was working on to fix the coding style, formatting and so on.

OK so I won’t be winning any "Best Linux kernel contributor" awards, but it’s nice to see my name in the changelog and know that I’ve actually contributed something useful.

Comment posting

Saturday, September 10th, 2005

I’ve just implemented a verification check for people posting comments, so now you’ll need to read/work out the text shown on the image when you post your comment and enter it into a text box. I hope this isn’t too annoying.

To be honest I don’t have much trouble with comment spam – I haven’t had any actually get live onto the site for a long time as Wordpress‘ in-built spam-fighting tools are pretty good (after several additions to the list of common spam words) – but anything which makes my life easier has to be worth it.

Most of the spam the blog receives is actually trackback spam, but almost all of it ends up in the moderation queue. It’s just annoying to have to keep clearing out the damm queue and there aren’t really any good trackback-spam-killers at the moment.

Anyhow, thanks to uberdork for writing the SecureImage plug-in.

A new BOfH book!

Saturday, September 10th, 2005

It’s about two years late, but finally there is a new BoFH book!
A book? Yes, you know those analogue data display terminals made from bits of tree?  ;-)

Anyway, it’s about a tenner delivered from the US (not available in the UK yet) so it will soon take it’s place alongside the other four books from the series on my book-shelf.

Anyone who has no idea what I’m talking about had better read the BOfH article at Wikipedia.
