I upgraded my notebook to Ubuntu Karmic Koala 9.10. As known from the other upgrade before, here was the same problem with the slow xorg. So I tried the other solution posted below but that won't work in this case. So I searched the Ubuntu Forum again and found the solution.

You just have to download the new driver posted in the link below, it's a beta version i know, but it works and install the driver, add in the following in the xorg.conf (/etc/X11/xorg.conf) file and reboot the system and enjoy the working X.

Add or if exist overwrite this in the Xorg.conf
Driver "sis671"

I was looking for an good alternative application to manage multiple domains, ftp accounts and mail accounts.
There are multiple applications but I tried the SysCP[1] online Demo[2]. This was exactly that what I wanted to have! So I downloaded it and installed it on a virtual machine.

The default configuration works fine on a Linux Debian 5.0 Lenny[3] www.debian.org. I had to investigate more time to setup the exim4[4] www.exim.org with mysql support, greylisting[5] www.tldp.org and antispam with spamassassin[6].

But now, all this stuff is running really fine and I need only 5 minutes to add a new customer with the full program :-).

I upgraded my notebook to Ubuntu Jaunty 9.04. All works fine but not the video card. The whole desktop (xorg) were very slowly, like a slowmotion in a movie. After searching in the internet for some minutes I found a good, quick and easy solution.

Huhu,

I will get my new flat soon and now I wanted to design the flat with the appliances.
At first I head to search for a useful tool what makes me happy with the result and is also easy to use.
Aaand, I found one. It's called SweetHome3D (www.sweethome3d.eu) and it's free for all. The most important thing is, that you can run it on several Operating Systems (Linux, MacOS, ...).

So, enjoy it and have fun!

I needed a command or script to scan the whole network for all active hosts/devices. Ok, a broadcast ping will do something like this but you should have enabled on the hosts to answer on broadcast pings (default not under Debian Linux).
So I tried a lot of things and this is the best solution for me. This command will give you a list for all active hosts.

for ip in $(seq 1 254); do ping -c 1 192.168.0.$ip>/dev/null; [ $? -eq 0 ] && echo "192.168.0.$ip UP" || : ; done

For using this on your network you only have to change the following values.

$(seq 1 254)		1.....start IP
			254...end IP
192.168.0.$ip		IP of network (e.g. 172.16.1.$ip)

Have a funny scanning ;-)
