potentially, they are set up to block pings. If you have nessus pinging them first, it can ignore machines that don't respond.
they could have countermeasures on them, like Sygate or PSAD On 2/8/07, Eric van Straten <[EMAIL PROTECTED]> wrote:
Hello, Nessus version: 3.0.4 Linux Client: 1.0.1 Previously I've been scanning just a handful of computers at a time and not noticed this problem... Yesterday, my boss came to me and asked me to scan 136 IP addresses and of those I got results for 107. Upon further digging I found that 16 of the addresses were at the boundary points of subnetted blocks... so I'm okay with those. What about the other 13?? These devices are up and active servers running internet facing applications (i.e. web server). Many thanks in advance! Eric ------------------------------ Want to start your own business?
