Personally, I use SNMP for read-only network gathering information. Depending on the device you are trying to poll, you can generally retrieve almost all information from a device. What you have described that you have already seems like SNMP. Can you give an example of a device that you want to 'test' against? Assuming that you have an SNMP v2 device available for polling, try this on your FreeBSD box: # pkg_add -r net-snmp # rehash # snmpwalk -v2c -c your_ro_community ip_or_name_of_device If you want specifics to test against, let me know off-list, and I'll give you a Cisco router to poll.
