/var/torrent/.scgi_local not accessible by www-data

This breaks certain apps that uses /RPC2 such as transdroid.

Possible solution includes moving the .scgi_local somewhere else or changing the group owner for /home/rtorrent.

Currently I'm just using setfacl to give www-data access to that one socket file.

Well, since rutorrent works, I guess it uses the socket directly. Try to add www-data to the rtorrent group, and restart (not reload) the web server.

Proper solution:

• a new rtxmlrpc group, with rtorrent, rutorrent, and www-data in it
• /var/run/rtorrent directory owned by rtorrent.rtxmlrpc
• socket at /var/run/rtorrent/scgi_local.sock owned by rtorrent.rtxmlrpc
