Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-questions@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk Hallo there, I am currently using FreeBSD as my organisation DNS server. We have roughly about 12,000.00 + numbers of users. Hell, lots of hanky panky is going around here. Question. 1.] How do I disable the TELNET and FTP function from the rest of the users, allowing only 1 administration station to be able to do that? 2.] How do I display a certain messages on the user screen the moment they try to TELNET to my FreeBSD DNS server. That means, instead of waiting for timeout, maybe there is a way I can display a message to them, giving them certain messages discouraging them from TELNETing to this server. Hope you guys can help me. Thanks.
