[jffnms-users] Problems with Autodiscovery (hosts and interfaces)

[Tim Carr]

Hello, all.   I’ve got JFFNMS up and running on an FC4 box.  After I put a zone in, the system won’t autodiscover either the hosts on that subnet, or the interfaces.  I have verified that the cron jobs are running:   Aug 23 14:30:01 jfftest crond[9030]: (jffnms) CMD (cd $JFFNMS && $PHP -q autodiscovery_network.php master $THREADS > /dev/null 2>&1) Aug 23 14:30:01 jfftest crond[9034]: (jffnms) CMD (cd $JFFNMS && $PHP -q autodiscovery_interfaces.php > /dev/null 2>&1) Aug 23 14:30:01 jfftest crond[9039]: (jffnms) CMD (cd $JFFNMS && $PHP -q autodiscovery_interfaces.php master $THREADS > /dev/null 2>&1)   If I manually run the autodiscovery for the network from the command line, it will run successfully and discover the hosts on my network.  Also, once hosts are in the database, if I manually run the “discover interfaces” (via the “manual discover” while using the web interface), it will also work.   Does this have something to do with these instructions from the installation guide:   . Compile and/or Install NMAP         Nmap should be set-uid root if you want UDP port monitoring & discovery to work.       Execute:         # chmod +s /usr/bin/nmap         # chmod a+x /usr/bin/nmap   I’ve run the two commands above as root while doing the installation…am I supposed to do something different?  Or…is this pointing at another problem all together?   Thanks, Tim
