The Suns are a 2/120 and a 2/50 running SunOS 3.0. How much would it be to get an upgrade from 3.0 to 3.5? --morris meyer Morris A.

McKay) Subject: Archive service now available To: suns-at-home Suns-at-Home now has an archive service available. I sat down last weekend and wrote a mail-in archive server to run on my sun. It's simple, not very clever, but it works well. To use the archive server, send mail to: "suns-at-home-archives@ea.ecn.purdue.edu" -- or -- "...inhp4!pur-ee!mckay!suns-at-home-archives" The archive server will read the body of your message and look for one of two command lines: send index -- or -- send DIR file The first form of the command line sends you a list of what's in the archives. The second form of the command retrieves file "file" from directory "DIR". The command line must be in the BODY of the message to work correctly. The current archive contents are: DIGESTS: vol1.issue1 vol1.issue2 vol1.issue3 SOFTWARE: --Dwight D.

Recently my group at Bellcore began to look in to high speed modems to allow some of the people in our group to bring sun workstations home and telecommunicate via SLIP. The ideal modems for SLIP are, of course, the fastest ones available. This generally means V.32 trellis coded full duplex 9600 baud, or the Telebit trailblazer standard. (So far as I know, the Telebit type modems are only made by Telebit and Ven-Tel; any confirmation on this?) We also wanted to be able to use the same lines for some normal interactive use for remote terminals. Because there is some existing local experience with the V.32 modems, and because Telebit modems aren't suitable for interactive use (they buffer things too much I understand), we decided to get some V.32 modems to test out. A bit of research showed that the cheapest available are the UDS V.32 modems, which cost us about $1200 each from a local distributer (C&S Data Solutions, Tel. No. (201)308-1800) which was about as cheap as you can get these things. The price was near $2000 until recently, and seems to be rapidly declining. We purchased 4 test units which we have been using for the past few weeks. I have been extremely satisfied with the performance of the test units. In fact, I am writing this message from home over one of them. The distance between my home and Bellcore is about 50 miles over lousy phone lines, and I have yet to see errors on the line except during a thunderstorm. I have only experienced one problem, which is that crosstalk between my voice and data phone numbers at home causes my modem to disconnect. I am planning on having the local phone company isolate the lines to fix this. Otherwise, the modems have been extraordinarily well behaved in the extreme. It is quite an experience to communicate over a long distance at the same speed that you get with a local telephone connection, and I would never, ever want to go back to 2400 baud. We haven't yet tested SLIP over these modems, but several other people at bellcore currently run 24hr SLIP connections between work and home with V.32 modems, so I anticipate no problems using the UDS units for that purpose. They seem to be far superior for SLIP than V.29 units which were previously used for that purpose. No one here, however, has tried Telebit style units so I don't know how they behave.

I see traffic is still light on this mailing list so I figure I might as well pipe up about a problem I'd like to get solved. I want a sendmail config file for my Sun at home which will forward all mail not destined for my machine to my uucp partner, which is an Internet site. Besides simply forwarding the mail, I want sendmail to hide my "uucp-ness" as much as possible, both from me and from the people I'm sending to. In other words, when I get mail from joe@foo.bar.edu, I want the headers on the message to say From: joe@foo.bar.edu, not From: im4u!foo.bar.edu!joe, and I want to reply to the message with that address and let my uucp partner figure out how to deliver it. I also want the From: address to be ronbo@vixen.uucp on my messages that are delivered to people on the Internet. I sorta have that now, but not really. I took the prototype sendmail.cf from the 3.4 release and added all the top-level domains I could think of to a special case it already had for CSNET and BITNET addresses. This works, except for the .uucp domain which I can't add because I'm in it, but it's ugly. I want to hand off everything, unless it's for this machine. Also, the sendmail.cf I'm using doesn't do header munging properly and it's loaded with cruft I don't need. Now, I know I could RTFM and hack it myself. I tried that once, I sat down and read all about rulesets and stuff. I hacked away for a couple of hours. All I succeeded in doing was giving myself a headache. I'll bet many people on this list are like me, a uucp leaf hanging off an Internet-connected site. So a sendmail setup which hands mail off to the "smarter" uucp neighbor would probably be useful to several of us. Has anyone setup their sendmail that way? Anybody want to volunteer?
