X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 28 Jul 2006 03:16:35 -0000 Two part question here ... first part ... is there a way of just disabling icmp by setting a sysctl, so that a server just doesn't respond to them? second part ... is there a way of telling a cisco switch to drop all icmp packets, preferrably to all but an exception list, but to everywhere works as well ... I'm running a Cisco 2950-24 ... thanks ... ---- Marc G.
