nmap scans hosts and reports if they are up, and what ports are open. Nessus scans for vulnerabilities. For example, "Does this system crash when sent an over-size ICMP packet?" It might test that by sending an over-size ICMP packet. If the system crashes, it is vulnerable. Granted, not all of the tests are so, um, intrusive, but you can see the potential for problems. Even if you select less hostile tests, it will still use more resources than a simple ping scan. Another thing the OP might want to check out is OpenNMS, at <http://www.opennms.org>. I've never actually used it, but we had someone give a talk on it at a GNHLUG meeting once. :-) -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
