Getting SNMPD to work on Ubuntu

Wolfgang — Tue, 22 Jun 2010 09:53:16 +0000

Setting up snmpd on ubuntu seems easy, but i never got it full working. It was working locally, but not for a cacti setup from another server. The problem was that the default install of snmpd on Ubuntu starts the demon on the loopback interface only, refusing connections from other computers. Edit /etc/default/snmpd to fix… Continue reading »

Using WordPress 2.8 and up with a proxy webserver in front

Wolfgang — Fri, 12 Jun 2009 01:15:37 +0000

I use a public plain apache server with mod_rewrite to serve my wordpress as i don't trust php enough to expose it to the world ;-) I wrote and updated a previous post describing what i've done to make things work for me, but now with Wordpress 2.8 it's broken, so i had to figure out a fix for this problem again.

Re-Flash LaFonera with original Firmware

Wolfgang — Sat, 03 Jan 2009 18:01:00 +0000

After playing around with my LaFonera and ddWRT i decided to go back to the original LaFonera firmware. I liked ddWRT for it's feature-richness, but as my requirements changed i don't need the router to sit inside the LaFonera and thought it would be good to re-join the fon community ;-) I found most of the commands to achieve this on Stefano Testi's Blog in this article. I ran into some problems because i tried this on Mac OS X, so i added some steps to this procedure to succeed.

I tried to do this with mod_rewrite and succeeded only partially :-( after some hours of hacking around with mod_rewrite and wordpress itself i got i working and want to share my solution: note: let's call the origin server SERVER A and the "new" server running wordpress and mysl SERVER B.

Icecast2 listener statistics script for Cacti

Wolfgang — Fri, 25 Jul 2008 14:47:20 +0000

I found a script for cacti to monitor the number of current listeners of an icecast2 server. The script was ok, but had a problem that sources where counted as listeners and it only showed the total number of listeners. I did some work on the script and it now has: - show all listeners… Continue reading »

Wolfgang — Mon, 10 Mar 2008 10:23:06 +0000

All clients and all volumes automounted as expected, except one volume on one of the clients I saw the client in the list for that particular volume in the XSan Admin application, but… Continue reading »
