Unfortunately there is no single command to block all Adult and offensive web site (let alone many commands that do so). If there was companies like Little Brother and Websense would not be in business. To block Adult content in websites you are going to need a URL web filter software like websense. To block the PCs that you don't want access to the Internet either: 1. Remove their default gateway if you have a flat network or 2. Remove the DNS servers from their TCP/IP stack. If you are using IE you can also put settings in IE to not allow any Internet Access. -Original Message- From: mrfestus wariye [mailto:[EMAIL PROTECTED]] Sent: Mon 12/17/2001 1:21 PM To: [EMAIL PROTECTED] Cc: Subject: need advice [7:29392] i have just finished my ccna programme and i am currently doing a 2 month internship programme with an outfit that runs a cyber cafe business that provides internet access services for the public. i am their interim network administrator. i have noticed a lot of loopholes in the network. and some of my problems i need answers to are:- 1. how do i use a single command line to deny access to all pornographic/adult sites on the network. 2. some computers within the network are denied access to network(to use network resources like the network printer).but the same computers can see the shared internet access. your useful advise would be appreciated. yours truly, festus taferi. __ Do You Yahoo!?

RE: need advice [7:29392]
Hello Festus: 1. This is a persistent and difficult problem. The short answer is, you can't. There are a lot of products like Cyberpatrol, but they are not on the router. Usually they are on the proxy servers, end PC's and firewalls. They can block a lot of sites but not all. Filtering based on word list is not entirely accurate, either. But they do work. Since you are just trying to block porn access in a cybercafe, they are probably good candidates. But -- they cost money. 2. The second question is more like a Microsoft question, not sure.

Hi Festus, I do not see anyway one access-list command can help you achieve your objective. If you were talking of chatting and other stuffs that uses a particular port number, then an access-list would be the answer. To use access-list, am afraid you have to know the IP addresses of these sites and block then individually. I will not advice you go this way, because it is going to slow down your router. If you are using a proxy server to connct to the net, Zonealarm is a freeware on the net, download zonealarm into the proxy server and have it deny access to these sites. However, if you are not using a proxy server, the handy solution for you depending on how technically sound your internet users are. Sometime in the evening when everybody have gone home, you need to go round each computer and do the following: Assuming you are using Internet Explorer 1. Click on the Tools then Pick Internet Options 2. Click on Content and Pick Content Advisor 3. On Content Advisor frame, Click on Enable then click on the Rating tab. 4. You have the option to restrict users to sites base on content of that site eg --Language, Nudity, Sex and Violence The is posisble because at registerations sites are classified accordaing to their contents and so each time anybody access the internet through that computer, it validate the site againt the database stored on the internet before pulling up that site. On your second question, Remember you have to login into the domain to be able to use the Network printer. Make sure, you are login and confirm from the NT PDC that that computer had actually login with a valid user ID. Also check privilidges and Access control list on the shared printer, make sure that everyone have Full access to the Printer. Regards.

RE: need advice [7:29392]
Question number one as far as I know is almost impossible. As for question number two you have two options, A)Access Lists or B)VLANS. Maybe others will have other alternatives. HTH!

I am planning on purchasing the "CCIE SECURITY WORK BOOK" for a Christmas gift. Any one have any feedback on this book or know of a cheaper price than $200?
