The most likely problem is Nessus is being run too hot and some packets are getting dropped or ignored.
Lower the Max Threads value and raise the timeout values. Although, I still predict you'll have some differences. On a given network of any size you will always have dropped packets (by the switches, routers, the workstations network cards, etc). Normal network traffic accounts for this as they expect a connection to occur and deal with dropped packets accordingly. Forged traffic (as in the case of Nessus) may not deal as gracefully. It doesn't know whether a packet was dropped or ignored by the end-point. -rjf -----Original Message----- From: Wespe, Andreas [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 24, 2002 3:11 AM To: [EMAIL PROTECTED] Subject: General Issues Hello, I have done several checks with nessus and repeated them twice.
