Evolution segfaulted with the following line in messages

[   56.897763] evolution[6320]: segfault at 0 ip b6a45d07 sp bff95824 error 4 in libglib-2.0.so.0.1800.2[b69e9000+b5000]

It turns out that importing fails on the ev-summary files in ~/.evolution/

The solution is deleting those ev-summary files. They will be regenerated by evolution. Because I have dozens of folders in my evolution I used the following line:

find ~/.evolution -name *ev-summary -print0 | xargs -0 rm

after that  evolution works just fine.

My install is a CentOS 5.2 installation but it should work under any fairly recent Linux distribution

Setting Poptop VPN for Iphone is done in just four steps:

1 Installing Poptop on your linux server

Some distributions already have pptpd, if not you can install it from source with the following steps.

Download the latest pptpd from Sourceforge.

Unpack pptpd, configure and run make install:

tar -zxvf pptpd-1.3.4.tar.gz
cd pptpd-1.3.4
./configure
make
make install

2 Configuring pptpd (poptop)

Now we need to configure the different files used by pptpd to setup up for the vpn:

/etc/pptpd.conf

option /etc/ppp/options.pptpd
localip 192.168.8.1
remoteip 192.168.8.234-238

/etc/ppp/options.pptpd

 name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
 
#opendns dns services, you can replace this by your dns provider
ms-dns 208.67.222.222
ms-dns 208.67.220.220
lock
nobsdcomp
nologfd

/etc/ppp/chap-secrets

# Secrets for authentication using CHAP
#set one or more username and passwords to use with the pptp VPN
# username    pptpd   password         IP addresses
username       pptpd   password        *

3 Setup the server for Masquerading/NAT

Because we want to share the internet connection of the server with the Iphone we need to do NAT. The following couple of lines enable this. I am assuming eth0 is the network interface conneted to the internet. Just first try this out by copy and pasting this into bash but to keep it working even after a reboot you can copy the following lines into /etc/rc.local

echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
/sbin/iptables -A FORWARD -i eth0 -o ppp0 -m state --state RELATED,ESTABLISHED -j ACCEPT
/sbin/iptables -A FORWARD -i ppp0 -o eth0 -j ACCEPT
 
#and start pptpd
/usr/local/sbin/pptpd

4 Configuring the Iphone

On your iphone click settings > network >VPN > Add VPN Configuration

Click PPTP and fill in a description
the hostname of the server
account = the username filled in in /etc/ppp/chap-secrets
RSA SecurID: OFF
password, as filled in in /etc/ppp/chap-secrets
Encryption Level = Auto
Send All Trafic: ON

Now press save and when Turning VPN to ON it should connect to the server.

If you have any problems don't hesistate to ask in the comments.

searching for web site hosting?

We need to build these drivers so make sure you installed the following packages

build-essential
linux-headers-generic

for the use of the usb stick itself we need: dvb-utils

these are all to be found in synaptics.

now unpack the file and go into it's directory and type:
(when compiling for second time or new kernel, "make distclean")

make all
sudo make install

now download the firmware (right click save-as) for the AF9015 and place this in /lib/firmware

then do a:

sudo modprobe dvb-usb-af9015

and it will load all necessary modules.
Type dmesg to check if everything loaded

use scan to find all the channels which are available to this by using the right file for your region:

scan /usr/share/doc/dvb-utils/examples/scan/dvb-t/COUNTRY_YOURREGION > channels.conf

this file you can us to view tv in xine or me-tv

I used netatalk-2.0.3

First time I tried to install under centOS5 I got an error

cnid_index.c:277: warning passing argument 2 of 'db->stat' from incompatible pointer type
cnid_index.c:277: error: too few arguments to function 'db->stat'

after some googling I found out that this has to do with support for an outdated Berkeley DB.

This can easily be fixed by editting to lines:

edit line 277 in "bin/cnid/cnid_index.c" and change:

ret = db->stat(db, &sp, 0);
to
ret = db->stat(db, NULL, &sp, 0);

on line 517 of "etc/cnid_dbd/dbif.c" you have to do exactly the same.

Now do configure & make:

./configure --enable-redhat --enable-cups --enable-pgp-uam --enable-krb4-uam --enable-krbV-uam
make install

now edit the config file in /usr/local/etc/netatalk/ according to your preferences.

mine is pretty basic:

afpd.conf

- -transall -ddp -uamlist uams_clrtxt.so,uams_dhx.so -nosavepassword

AppleVolumes.default

/home/tim allow:tim
/home/pieter allow:pieter
/home/wytze allow:wytze
/home/samba allow:wytze,thijs,tim,piete

Automatic redirect to ssl host https:

In case you want to automatically redirect to https to make sure people use the secure connection put the following code in your .htaccess.

Always make sure to use %{HTTPS} off as condition and not any port number.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Custom "page not found" or other error pages

ErrorDocument 404 http://errorurl/
//or the following
ErrorDocument 404 /edocs/404.htm

Make sure host uses UTF-8

if you create websites for others and use a lot of different hosting providers you may notice not everyone uses utf-8. This might create some difficulties with certain characters. Adding the following line to your .htaccess makes sure your host uses utf-8.

AddDefaultCharset utf-8

Code I always put on top to prevent problems with some hosts

-Indexes makes sure your folders aren't indexable from the web. This might prevent some unwanted peeking around on your server colocation.

Options -Indexes +SymLinksIfOwnerMatch
