I have a new install of ONA on a Ubuntu 10.04 server. I have everything up and running but the nmap cron job. I can manually submit the command and specify a subnet to scan with the -n parm, but I can not run the command any other way. If I do the -l parm I get an "ERROR => The requested module is not valid!" message. It seems like it will not look at the ONA database to get the list of subnets to scan.

Its possible your environment does not have all it needs when running from cron. If you are able to use dcm.pl with no issues from your normal login then I think you'll need to check into crons environment. It needs to be able to find its config file etc

my /etc/cron.d/ona file looks like this:

# Please store only OpenNetAdmin related cron entries here.
#ONABASE=`cat /etc/onabase`
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin/:/opt/ona/bin

# Perform a daily nmap ping scan and update last_response
# Found it is best to ping during the day to pick up laptops that might be gone at night
0 11 * * * root nmap_scan_cron -u -a > /dev/null 2>&1


The PATH statement at the top ensures it can find stuff in the ONA bin directory.

One other thing to make sure of is that the command "dcm.pl --list" returns a list of modules. specifically look for "ona_sql"..

then try this command to see if it works correctly for you

dcm.pl -l admin -r ona_sql header=no sql=nmap_subnets_only_yes.sql


This is what nmap_scan_cron does to get the list of subnets from the database. You must set the -a option for nmap_scan_cron to get all subnets or you must set the custom attribute "nmap_scan" to Y for the subnets you want to scan.

hope that helps. Thanks
