Switching from Ubuntu to OpenSuse

Yes, I just switched my desktop computer from Ubuntu to OpenSuse.

I am sure that some people won’t believe it or think that I am stupid or that I work for Microsoft, but here are the reasons of this choice.

Compile Hping on OpenSuse (and maybe others…)

I could not find any package for Hping3 in the repositories of OpenSuse (both official and non official). However, the source of Hping3 is available here and (almost) ready to be compiled. Almost ? let’s see why…

SSH timout

After a fresh set up of your network, don’t be surprised that your ssh connections are slow.

Opera segmentation fault after upgrading

For those who have a segmentation fault after the last update on Feisty (libx11 upgraded)…

Ethernet duplex issues

I had a weired issue with a server. Whereas other machines worked well with an high speed Internet connection, dowloading was painfully slow on this one. The network card, a 3Com, was also different from others (Intel).

ACL on Linux

Rights management on Linux is enough for most use.
In a few words, a file or a directory belongs to the owner and what you can do is positionning some right to this owner, to his group or all other users (= guests).
This is not bad, but sometimes you (or your application) may need more advanced right management, as on the latest windows versions : putting several owners with different rights, inheritance, etc.
There are named ACL (Access List Management) and they are supported on Linux also.
This is not going to be an how-to but just a brief informative introduction to ACL on Linux. You will find many how-to on the web if you need more.
