Yeah, I found it. While researching replacing the 2.2 kernel with 2.4 to get my proxy-oid to work, I stumbled accross the following section in the unofficial NAT-HOWTO (which is not on linuxdoc's website as far as I can tell). At this address: http://netfilter.kernelnotes.org/unreliable-guides/NAT-HOWTO/NAT-HOWTO.linuxdoc-4.html Under section four ("quick translation from 2.0 and 2.2 kernels"), under the heading "Hackers may also notice:", item two in the list: >The (undocumented) `getsockname' hack, which >transparent proxy programs could use to find out the >real destinations of connections no longer works. Ah! A clue! But no idea how to make it work under 2.4, and no mention of what replaces it! (I read the rest of the howto carefully. Never mentioned this topic again.) But there IS a way to get it to work under 2.2, if I can learn an undocumented (but functional) hack. So I jump to the contents page to see who the HOWTO maintainer is to ask rather pointed questions. His email address isn't listed, but I do I find out that the netfilter mailing list is at [EMAIL PROTECTED] http://list.samba.org turns out to have a page of hosted lists, with a link that eventually leads to an archive, which is not easily searchable except by date. Fun. This brings us to google, which can find anything if you just know what to ask for. I search for "lists.samba.org netfilter getsockname". The first hit is just that silly howto again, but the second hit: http://lists.samba.org/pipermail/netfilter/2000-September/005317.html An explanation, complete with example code. From september of last year. And there was much rejoicing. If I were to perhaps send linuxdoc.org a check or something, might a day come to pass when learning to do seemingly obvious things under linux does NOT require fairly good forensic investigation skills? I ask merely for information. I need to get more caffiene now. I'm going to be up REALLY late coding. :) Rob __________________________________________________ Do You Yahoo!?
