Update
Since DSM 5 the paths are changed:
DSM 4:
- /usr/syno/etc/httpd-ssl-vhost.conf-user
- /usr/syno/apache/conf/httpd.conf-user
DSM 5:
- /etc/httpd/sites-enabled-user/httpd-ssl-vhost.conf-user
- /etc/httpd/conf/httpd.conf-user
I’m an owner of a Synology DS211 and i have installed Sabnzbd+ on it, using this helpful package http://synoblog.superzebulon.org/2011/09/sabnzbd-0-6-9-1-spk/ (add it to your favorites, it’s a really nice site with more packages to download).
My Synology is running on the latest 3.2 firmware.
After installation Sabnzbd+ is running on the following address http://private-diskstation-ip:8080, and i wanted to make it accessible in a secure way from the internet.
I want to be able to access the sabnzbd+ instance only from https and with a user/password prompt.
