Roundcube PHP Update conflict

by Leave a Comment

Another tricky error after Debian squeeze upgrade:
ERROR: Wrong ‘suhosin.session.encrypt’ option value. Read REQUIREMENTS section in INSTALL file or use Roundcube Installer, please!

The fix is very trivial:

1
2
3
4

vim /etc/php5/apache2/php.ini
# Add this lines to the bottom of the config:
[suhosin]
suhosin.session.encrypt = Off

Solution for php5-fpm:

1

php_admin_value[suhosin.session.encrypt] = Off

To upgrade the database style to roundcube version 0.9.0 I used a little workaround to prevent suhosin error reporting:

1

php -d suhosin.session.encrypt=off -d date.timezone=Europe/Berlin bin/updatedb.sh --package=roundcube --version=0.8.2 --dir=`pwd`/SQL

Maemo be root

by Leave a Comment

After my failed android installation I try to restore my old state of my N900.

Here’s how to get root access:
1. Go to Application manager > Application catalogs -> New
2. Write maemo.org extras-testing for catalog name
3. Give web address as http://repository.maemo.org/extras-testing
4. Enter fremantle as the distribution
5. Enter free non-free for components

Now simply install rootsh from Application Manager.
Once you are done with rootsh, open a terminal.

You can now either try sudo gainroot and you will be root.

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.
After some unsuccessful tries with openswan:( I decided to try OpenVPN and I had luck I found very useful blog of (Sébastien Wains) which was my clue to my working VPN.

I draw a little map of my VPN setup:

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
