RandScan Free v1.1 Stealth multi-function port scanner.

Features:

• Stealth scan by generating random IP addresses in a user-specified range.
• Stealth scan by incrementing the IP address (a.b.c.d) in reverse order (increment a´s, then b´s, etc).
• Scan a list of addresses from an input file or a single remote host.
• Automatically look up host names for connected ports.
• Select number of sockets in multi-socket data collection.
• Five different logs of results to files for later analysis:
  1. Session data
  2. Found Hosts
  3. Connection Transcript
  4. Events & Errors
  5. Refused Connections
• ONLY from Global Services, a NEW Filter function to more than double the speed of finding remote hosts.

And RandScan does not "invade" your computer -- no changes to your registry, no files in your Windows directory. Unbelievable, but true: "RandScan rocks."

NEW...protocol-specific probes added for ports 53, 113, 443, 1080 and 1433 and command-line arguments to run from .bat file.
