I would like just to mention that for new version of python 2.5 and latest versions, tentakel works fine with the patch specified at:
http://bugs.gentoo.org/attachment.cgi?id=177786&action=view

Thanks for your help!

if you have python2.5 like on my ubuntu system
you must install from svn

http://sourceforge.net/tracker/index.php?func=detail&aid=1581326&group_id=76769&atid=548189
“I checked in a fix. You can try it out by checking out the development
version of tentakel using the following command:”

svn co http://svn.tuebingen.mpg.de/tentakel/trunk/
cd trunk/tentakel
make ; make install

Another possibility is fanout. I quite like fanterm where the output is collected in xterm like windows. Helps keep things organized for me. Groups in tentakel looks handy. Thanks for the article nixcraft.

Thanks for mentioning tentakel in your blog. You also mentioned rgang, which looks nice indeed. However, there are two reasons why I don’t like rgang: 1) the license is not as free as tentakels (at least it does not look like as far as I can tell without being a lawyer) 2) it looks much more unmaintained thatn tentakel :)

Expect. Is very nice back in Solaris day I had complete monitoring system written in rsh and expect tool. Open advantage of ssh is that it provides API for C/C++ programs. So I get performance

Anonymous user thanks for sharing your script with us. ,appreciate your post.

If your somewhat traditional, just use Expect. Does most of the same, has tons of examples around, a cool book (Exploring Expect). And you can handle stuff that NEEDS a terminal like ssh password prompts or the password program to change passwords.And it works on windows.

It seems a nice tool and using ssh it will be secure (as long as no-one knows the privat key ofcourse).

For a more simple variant I use a sh-script to execute on all machines in my (linux-)network:

ping -c 2 -w 10 -b 192.168.13.255 2>/dev/null | sed -n -e ‘s#^.*bytes from ([^:][^:]*).*#1#p’ | while read ip
do
name=`host ${ip} | sed -e ‘s#.* ([^ ][^ ]*).$#1#’`
echo “— ${name} : ${*}”
rsh ${name} ${EXTRA} “${*}”
done

I can confirm that it is possible to run Tentakel on Windows, albeit with a bit of modification to the source (about 7 lines total). I posted the details over my blog: Running Tentakel on Windows

RGANG looks good too. It incorporates an algorithm to build a tree-like structure (or “worm” structure) to allow the distribution processing time to scale very well to 1000 or more nodes. Looks rock solid.

Thanks for pointing out I appreciate you post :)

Fermilab has a much more feature rich tool named rgang. More info: rgang abstract and download

Stoyan, SwitchTower seems good choice for windows :) as I may soon start work on windows too, I appreciate you post.

Or if you like ruby, use SwitchTower. Have native ruby ssh client = will work on windows too.
