Had an interesting case with DNS wildcard records: if you have a wildcard (*) A record – it works pretty fine, but if you specify a CNAME record to point to non-existing A record (which would normally be satisfied by wildcard A record) it won’t work, at least in the case I had. So as an example if you have:

Zone file for domain1
* IN A 111.111.111.111

Zone file for domain2:
host1 IN CNAME host1.domain1.

Then any query for host1.domain1 will resolve with no problems, but when you will try to resolve the host1.domain2 – it will fail. For this case you need to explicitly specify the host1.domain1. as follows:

Zone file for domain1
host1 IN A 111.111.111.111
* IN A 111.111.111.111

Interesting case, just to remember for the next time…

As I am finishing my job at Satlink Satellite Communications and will discontinue at my current position there from the next month, I am looking for a new opportunities. Through I was mostly involved in software development and only minor system administration at a current position, I am more of a sysadmin guy then a programmer anyway, but can do more than just one thing :)

If anyone is looking for an IT guy like me in Limassol, please let me know and we can discuss.

You can find my CV in Resume section of my blog and I am also attaching a PDF version of it my_cv.

Just noticed that Delete button in Nautilus of GNOME3 does not delete a file. Either Shift+Delete should be used to delete file completely or Ctrl+Delete for normal removal to Trash.

If you use Nautilus a lot and would like to get normal (old-style) behaviour, check out these post: http://www.khattam.info/howto-enable-delete-key-in-nautilus-3-fedora-15-2011-06-01.html

Basically you need to enable accels key editing in Gnome with gsettings (or gconf-editor), then reassign a button you wish and then disable change of accels key back (unless you want to have it permanently on, which I don’t advice, otherwise you might mess a bit by accident),
