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 …

Ubuntu: networking tip

Wolfgang — Mon, 26 Feb 2007 13:18:47 +0000

But when i tried to ping some other machine, this didn't work :-( I checked /var/log/messages and the onboard Broadcom Interface showed up as eth1, but i was not able to start it. When i ran $ sudo /etc/init.d/networking restart i got some error messages like: SIOCSIFADDR: No such device eth1 eth1: ERROR while getting interface flags: No such device No clue what went wrong, i googled a lot and finally i stumbled upon this forum entry: http://ubuntuforums.org/showthread.php?t=221768 Then i ran: $ ifconfig -a and got a list with my network interfaces and more importantly with it's MAC address.

Ubuntu Server insecurity?

Wolfgang — Mon, 19 Feb 2007 13:35:04 +0000

i just found out that my Ubuntu Server 6.10 has login shells for almost all users set in the /etc/passwd file! That's a very bad idea because this maybe enabled someone to install "Data Cha0s Back Backdoor" on my machine :-( I checked this with 2 other fresh Ubuntu Server 6.10 installations and both also had the login shells for users like daemon, mail, www-data and so on. Especially www-data should not have a chance to create a shell in my opinion!

The power of vim

Wolfgang — Wed, 22 Mar 2006 07:30:45 +0000

vim is the commandline text editor vi (improved) and it features syntax highlight and colors. The good thing is, vim is included by default in Mac OS X – the bad thing is, color support is not enabled by default. To enable syntax highlight in vim create a .vimrc file in your home directory: ?View …
