iperf3: a Network Bandwidth Tester
Thu, Apr 21 2011, 13:06 networking, server, software PermalinkI was investigating my WiFi access points for improvement and while browsing the web for ideas I came across iperf3. Simple and effective, iperf3 is a tool to measure network bandwidth (read more about it ...)
To simplify installation, I created a MacOS X (Intel) installer package for iperf3 so you do not need to compile yourself.
(download iperf3.pkg)
An Universal Binary Installer Package for MacOS X can be found on NCSA Illinois, although that is iperf2.
(download iperf.pkg)
Simple 1-2-3 Network test:
Install iperf3 on a Mac where you start it as a server: open Terminal and enter the following:
iperf3 -s
Then install it on another Mac and run it as a client: open Terminal and enter:
iperf3 -c 192.168.178.131 -t 60 -P 2
where you must replace this IP-address with yours where iperf3 runs as a server on.
Wait a minute (-t 60) and the results are presented as follows:
Connecting to host 192.168.178.131, port 5201
[ 4] local 192.168.178.13 port 65334 connected to 192.168.178.131 port 5201
[ 5] local 192.168.178.13 port 65335 connected to 192.168.178.131 port 5201

To stop the server, press CTRL-C.
Enter iperf3 --help for all possible options.

Weingut Alfred Franger & Sohn
Fri, Apr 01 2011, 20:00 Drinks, Travel, Vacation, Wine PermalinkLast week a friend and colleague of mine took me to visit a vineyard in the region where we work. After a 30 minutes drive we arrived in a small village called Heuchelheim-Klingen where Weingut Alfred Franger & Sohn is long-standing. My friend knows these people for over 15 years already and we were very friendly welcomed. And after 15 minutes we were already in the wine-tasting room! I told the lady of the house that I lately find that most German wines all taste the same, in some way. She began to laugh and told me that the taste I meant, is typically for this region! So she poured a centimeter of a light red wine, and that was exactly the taste I meant. Then we went on to taste some other red wines - and oh man, was I surprised! Completely unexpected flavours of oak, lychee, smoked wood, vanilla and more. | ![]() |
Their son, who is also in the family-business, joined us and he is really full of enthusiasm and has a drive to make the best wines and trying out new ways of doing this! We were given the honor to taste a wine, bottled last weekend, made through a completely new and daring process. Well, even a week old, this young wine was really fantastic!
My friend had planned to go here anyway to buy a few boxes. But he was by car! I had come to work by train. So I just picked one bottle of each wine I was allowed to taste during our pleasant conversation and dragged a box home with me.
Being with real wine-lovers and talking about wine and such, is always very nice. So I list here some of their, all very good!, wines, in no particular order (but it might be alphabetic), and my favorites are marked:
