Hi Janet,
Thanks for replying. I've taken a look at the repo you linked and I couldn't see nor search for the vnstat contrib. I set up the SME8 contrib repo anyway and tried to install in case I has having a stroke but yum couldn't find an install target either.
The wiki article for vnstat says it was originally in the dag repo which now seems to be defunct.
If you could please post a direct link to the rpm file, I would appreciate it.
Anyway, If I browse to the old vnstat ibay I had set up, the php files are still there and displaying blank graphs as there is no data being collected as the vnstat program is not there.
Thanks.
