Not to nit-pick but I do like to explore all angles. I do not think you need to put in an external dns ip if you are on a LAN with a proxy. I think, I could be wrong, but the dns, internal or external, will forward the ip, sort of like a bootp helper address, in instances where it cannot find name resolution. I think that a dns server, at last resort will forward to arin,internet, etc.. Any thoughts? >From: "Augusto Bott" <augusto.bott@via-rs.net> >To: <freebsd-newbies@freebsd.org> >Subject: Re: hostname on standalone machine >Date: Fri, 21 Jul 2000 04:59:24 -0300 >MIME-Version: 1.0 >Received: from [204.216.27.18] by hotmail.com (3.2) with ESMTP id >MHotMailBB414D3D00A3D82197EFCCD81B1266EC0; Fri Jul 21 00:57:26 2000 >Received: by hub.freebsd.org (Postfix, from userid 538)id 250D537B6FA; Fri, >21 Jul 2000 00:56:34 -0700 (PDT) >Received: from localhost (localhost [127.0.0.1])by hub.freebsd.org >(Postfix) with SMTPid 1DE5D2E816F; Fri, 21 Jul 2000 00:56:34 -0700 >(PDT)(envelope-from owner-freebsd-newbies) >Received: by hub.freebsd.org (bulk_mailer v1.12); Fri, 21 Jul 2000 00:56:34 >-0700 >Received: from smtp-2.ig.com.br (smtp-2.ig.com.br [200.225.157.61])by >hub.freebsd.org (Postfix) with SMTP id DF91537B6ECfor ><freebsd-newbies@freebsd.org>; Fri, 21 Jul 2000 00:56:26 -0700 >(PDT)(envelope-from augusto.bott@via-rs.net) >Received: (qmail 18624 invoked from network); 21 Jul 2000 07:59:33 -0000 >Received: from unknown (HELO ig) (200.213.75.234) by smtp-2.ig.com.br with >SMTP; 21 Jul 2000 07:59:33 -0000 >From owner-freebsd-newbies@FreeBSD.ORG Fri Jul 21 00:59:30 2000 >Delivered-To: freebsd-newbies@freebsd.org >Message-ID: <00fe01bff2e9$97676260$0201040a@ig> >References: <Pine.GSO.4.05.10007211234350.26378-100000@cat.cs.mu.OZ.AU> >X-Priority: 3 >X-MSMail-Priority: Normal >X-Mailer: Microsoft Outlook Express 5.00.2314.1300 >X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 >Sender: owner-freebsd-newbies@FreeBSD.ORG >X-Loop: FreeBSD.org >Precedence: bulk > >Hi Andrew! > >And gurus, forgive me if I'm saying somethig wrong.... > > > connection to the outside world is via a dialup PPP link with dynamic IP > > address.
