I use Let's Encrypt SSL certificate for my website boredom.gotdns.com

Try to use script to auto renew when days < 30 days

Below is the sample.

If you use dyndns dns service and receive the mail like this

FAILED:   updating boredom.gotdns.com: badauth: Bad authorization (username or password)

And you check your config is right, no mater what os, like debian or windows.

Use the command to test ddclient config,

root@myla:~# ddclient -daemon=0 -debug -verbose -noquiet

At the last output you will see

Move Windows LAMP to Debian 8 (Jessie) and use Nginx to replace Apache, also setup rewriting http to https.

for apt installing latest packages

root@boredom:~# echo 'APT::Install-Recommends "0"; APT::Install-Suggests "0";' > 99recommended

backup source

root@boredom:~# cp /etc/apt/sources.list{,.orig} && vi /etc/apt/sources.list

add testing sources
for Debian Jessie
