Hi Greg, root@smokeping-master:/var/lib/smokeping/Local# chmod g+w :/var/lib/smokeping/Local chmod: cannot access `:/var/lib/smokeping/Local': No such file or directory
So I run following command on master and slave without any error: root@smokeping-master:/var/lib/smokeping/Local# chmod g+w -R /var/lib/smokeping/* Now I can't find an new error in the apache log file (since the last 15 minutes) but I'm still not seeing the Graph on the website from the master :( Any idea?

See: drwxr-xr-x 2 smokeping www-data 4096 Jul 1 14:28 . drwxr-xr-x 6 smokeping www-data 4096 Jul 1 14:28 .. So, assuming I'm right: chmod g+w :/var/lib/smokeping/Local This would make that directory RW for the group [www-data] However, I'll be surprised if the slaves can write to the RRD's either, since they're also r-- for the group, so you'll probably want to use the same chmod command on them. -Greg Thank you for your reply. root@smokeping-master:~# ls -al /var/lib/smokeping/Local/LocalMachine.smokeping-slave1.slave_cache ls: cannot access /var/lib/smokeping/Local/LocalMachine.smokeping-slave1.slave_cache: No such file or directory If I run it in this way I got the following output: root@smokeping-master:/var/lib/smokeping/Local# ls -al total 11688 drwxr-xr-x 2 smokeping www-data 4096 Jul 1 14:28 . drwxr-xr-x 6 smokeping www-data 4096 Jul 1 14:28 .. -rw-r--r-- 1 smokeping www-data 2986808 Jul 3 20:02 LocalMachine.rrd -rw-r--r-- 1 smokeping www-data 2986808 Jul 1 14:28 LocalMachine~smokeping-slave1.rrd -rw-r--r-- 1 smokeping www-data 2986808 Jul 1 14:28 LocalMachine~smokeping-slave2.rrd -rw-r--r-- 1 smokeping www-data 2986808 Jul 1 14:28 LocalMachine~smokeping-slave3.rrd root@smokeping-master:/var/lib/smokeping/Local# Thank you and regards Tobias Von: smokeping-users [mailto:smokeping-users-bounces+tobias.ackermann=kion-ims....@lists.oetiker.ch] Im Auftrag von Gregory Sloop Gesendet: Freitag, 3.
