Config with sntp V3:

net-snmp-config --create-snmpv3-user -a "mypassword" my_user
ln -s /usr/share/snmp/snmpd.conf /etc/snmp/snmpd.conf

/etc/snmp/snmpd.conf :
rwuser snmp


Debug info say, uit has to work, snmp also works:

Maby it's of php's disabled functions?

disable_functions = shell_exec,proc_close,proc_get_status,proc_open,popen,pclose,system,passthru,escapeshellarg,escapeshellcmd,fork,symlink,dl,phpinfo

?

Hi

have you run the poller at least once ?

vixie cron is set to:

*/5 * * * * php /var/www/localhost/htdocs/cacti/poller.php > /dev/null 2>&1

everything was installed two days ago.

[fmangeant]

Can you try to provide the full path to php in your crontab entry ?

Also, can you run the poller once by hand :

Code: Select all

$ php /var/www/localhost/htdocs/cacti/poller.php

[Fenixoid]

box ~ # php /var/www/localhost/htdocs/cacti/poller.php

Warning: exec() has been disabled for security reasons in /var/www/localhost/htdocs/cacti/lib/poller.php on line 127

Warning: popen() has been disabled for security reasons in /var/www/localhost/htdocs/cacti/lib/rrd.php on line 40

I deleted shell_exec, popen from disabled function list, but no effect.

How to run this stuff in safe, secure mode? I don't want to leave shell_exec, exec, popen function available.

[fmangeant]

Is it a Linux box with SELinux enabled ?

[Fenixoid]

No, it's gentoo simple dedicated server, just some advanced security (php, snort, mod_security...)
