Has anyone else ran nmap udp scans against Cisco devices and noticed a VERY slow and unpredictable response? Specifically, I am scanning 10 Cisco devices, 2950, 3550, 4506 and PIX 535.
All of these components are taking a very long time to complete the port 1-65535 udp scan. By "very long time" I mean close to 2 days. Estimated time is about 1 udp port per .8 seconds. Some of the components are giving me "unreachable" on all ports scanned and others are not sending any responses back. IOS versions running are 12.1(20) and 6.3(3). "no service udp-small-servers" is configured on all devices. I have tried increasing the timing policy as well as allowing nessus to choose the ports to be scanned and we are still running into long delays. Any ideas? _______________________________________________ Nessus mailing list [EMAIL PROTECTED] http://mail.nessus.org/mailman/listinfo/nessus
