We are currently in the process of establishing a corporate UseNet network. It will consist of Cnews servers, interconnected using nntp. Due to management concerns over copyright infringements and viral attacks I would like to know if anyone is familiar with filters that may be applied against a file to determine if it contains an uuencode binary. Also, would it be possible to include such a filter in the nntp stream so that files containing the information could be intercepted and removed or redirected. Please email any info that you have and summarize in a later posting. Thanks in advance. -- Dave Moore dmoore@hou.amoco.com Amoco Corp.

Although I understand your concerns, I assure you that you are using the wrong means to protect against them. Copyright infringments can come over non-uuencoded forms (excerpts from books springs to mind, because of the recent flurry over them). Viral attacks can come over from e-mail (the Internet virus) or people who don't watch their Bourne shell auto unpackers while running as root..... I'd say that it'd be a productivity loss more than a legal gain. What happens if I want to send someone at your company a source package? I usually tar, compress, uuencode them. What? A uuencode filter??!?!? Well, I'll just have to crypt or btoa it then. Are you going to have a btoa filter too? Education is the best means to solve your problems. Also, cut out the feeds that are most likely to have virii or copyright infringments on them. Cut the alt.* and rec.* feeds, cut the comp.binaries.* feeds, comp.source.* feeds, if you are really paranoid. You are not attacking the real source of your problem, ignorance on the part of your users, and ignorance on the part of people who post stupid things. I think you should work on the human element before blaming or "fixing" the electronic one.

Such functionality should be part of the news system, not NNTP. I would guess that the news relay and news posting functions of CNEWS could be modified to do this. However, you'll probably have to do this yourself. NNTP will not support such features and no plans are on the drawing board to include such features. It is not what NNTP does. -- Stan internet: sob@bcm.tmc.edu Director, Networking Olan uucp: rutgers!bcm!sob and Systems Support Barber Opinions expressed are only mine. Baylor College of Medicine
