 |
|
I have a problem in graphing ping latency using advanced ping template. the graph always show a constant 100% loss as you see in the attached graph.
when I run the script using root account no problem happend:
| Quote: | [root@nms cacti]# php /var/www/html/cacti/scripts/ss_fping.php www.google.com 20
min:154.7600 avg:156.2960 max:159.0200 dev:1.0255 loss:0.0000
[root@nms cacti]#
[root@nms cacti]# |
but using other users like cactiuser i got the following result:
| Quote: | -bash-3.1$ php /var/www/html/cacti/scripts/ss_fping.php www.google.com

This is an issue in Linux/Unix that prevents ICMP sockets to be created by anyone other than root. So, if your poller runs as root, you should be ok. Otherwise, you have to set the euid of php to root. A good way of doing that is to copy the PHP program to a custom location, make only the poller have access to it and then set the setuid bit on the application. Then in cron, make sure you start poller with this special php program. I have not tested it, but it might work. Don't know. Running the poller as root will though.
