It appears the cacti_host_template_fail2ban.xml template can only be imported under the latest Cacti, 0.8.6j, released 01/17/07, without incurring the dreaded "XML hash failure".
 
Unfortunately, there are not that many Cacti installations running 0.8.6j (mine included ;-))
 
Does anyone have a template that could be imported under release Cacti 0.8.6h or earlier?
 
If not, are there other helps that could be provided to build a template "from scratch"?
 
Much tnx,
 
Harry
