Fix: Filesystem notification initialization error

by 5 Comments

I upgraded my Mail-server to Debian 6 – squeeze, it was everything great till I started my Thunderbird and get this Message: Filesystem notification initialization error — contact your mail administrator (check for configuration errors with the FAM/Gamin library)

This error can be seen in your mail client and is often caused by Courier. If you are the administrator of the mail server, simply install libgamin instead of libfam as follows:

1

aptitude install gamin

Now restart all courier services:

1

find /etc/init.d/ | grep courier | while read line; do $line restart; done

OpenVPN site to site setup

by 6 Comments


Before I changed to OpenVPN I used racoon IPSEC tool. It was very unstable for my setup, because one VPN site has a dynamical IP-Address and only with dirty workarounds was it possible to use it.

Debian join windows domain

by 20 Comments

1. Introduction

I recently was assigned the task of joining a Debian server to a Windows Server 2003 Active Directory domain. Though most of the documentation I read for doing this was rather straightforward, 100% of that documentation turned out to be only 75% useful. While all were easy to follow, at the end of the day I found myself piecing together bits of information from all different sources. Only after deciphering cryptic log messages, consulting my colleagues, and experimenting did I finally have this working. Here I try to provide a complete walkthrough of this joining procedure, paying close attention to the often overlooked details I encountered in my trials.

I use:
Debian squeeze
samba 2:3.2.5-4l
winbind 2:3.2.5-4l
krb5-config 1.22
krb5-user 1.6.dfsg.4
