X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 23 Jun 2004 12:29:07 -0000 My question is: Does such a utility exist? I know nmap can guess os, but it takes a few seconds and a port scan is needed first. Is there just a simply util that can tell me without the port scan? Thanks!
