DNS Cache Poisoning

Jul 28th

Posted by Clifford W. Hansen in Debian

Alot of people might know about this, but in case you don’t, there was a vulnerability found in the DNS system, the servers that convert http://nighthawk.co.za/ into a number that computers can understand

Basically what this means is that if someone wanted to they could cause you to go to there server instead of the server you wanted, banking for example

Well a nice simple way to test would be the following:dig +short @ns1.example.com porttest.dns-oarc.net TXT replace ns1.example.com with the DNS server you want to check, of cause this would only work from a Linux machine

Good luck, and hopefully your ISP has taken the precautions they need to.

ps. If you running Debian Etch with the latest security patches, you should be fine :)

Canon iP1800

So the other day we went out and finally bought a printer

We chose the Canon iP1800. It’s not exactly the printer we wanted but it will do the job.

Well get home and connected it to Cecilia’s old laptop (which is running Debian Etch), and lo and behold it’s automagically picked up, so just needed to configure cups and samba.

Well added the printer with the default drivers (as I couldn’t find any that worked), and shared it via samba. Then installed it on Cecilia’s laptop (xp) and the drivers on the disk worked

One down, three to go. Then finally today I managed to find some drivers and got them installed

Original article was a little help, well it had the drivers. then just needed to issue the following commands: NNB: This will “break” your install
% sudo dpkg -i --ignore-depends=cupsys --ignore-depends=libc6 cnijfilter-common_2.70-2_i386.deb cnijfilter-ip1800series_2.70-2_i386.deb

%

You will note that I added a couple of –ignore-depends items, this is just for Etch, as Lenny has the required packages.

Then via the cups web interface I changed the driver and pointed it to the ppd file in: /usr/share/cups/model/custom/canonip1800.ppd. then printed a test page and voila

Happy printing!!

Now that explains alot…

So the last couple of weeks Catelyn’s been a little “sick”, coughing and nappy rash.

Well she’s almost fine now, but the reason for this was due to her getting four more teeth :)

Checked the other day and could feel three, but this morning I felt a fourth…

So like I said, that explains alot…
