I think you were right Greg !

But the problem is that the permission are setup this way:

root at ubuntu:/home/nml# ll /var/lib/smokeping//Local/
total 4976
drwxrwxr-x 2 smokeping smokeping    4096 Apr 15 23:37 ./
drwxrwxr-x 5 smokeping smokeping    4096 Apr 10 22:38 ../
-rw-rw-r-- 1 smokeping www-data  1688648 Apr 16 00:36 Google_FR.rrd
-rw-rw-r-- 1 smokeping www-data  1688648 Apr 15 22:18 
Google_FR~ubuntu.rrd
-rw-rw-r-- 1 smokeping www-data  1688648 Apr 16 00:36 LocalMachine.rrd

How can I resolve the issue ? :()

Thanks !

Nic
