It appears SLIP was designed for people who want to extend their IP
universe from work to home. I'm sure that it works fairly well for
this. But now organizations can use it to connect with the Internet.
The logistics of using it for this seem awkward. Would those who are
making use of this service kindly tell me how they make it work?
Here's how I suppose it works:
User dials up the network service provider using tip, and logs in with
a name and password.
In another window, you run "slip-attach" to configure the interface.
Then you do your ftp, or whatever.
Then you kill the slip-attach process with -HUP and somehow get the
modem to hang up.
There are several things wrong with this picture.
1. Am I supposed to tell all our users our login name and password on
our providers equipment? Seems like a security risk to me.
2. Who pays the phone bill when a user forgets to hang up after a
session?
[ A/UX 2.0 - specific ]
3. Based on my very limited experimentation, killing slip-attach (or
whatever it's called) on the Mac sometimes leaves grunge around so that it
cannot be run again without rebooting the machine.
It seems to me, because of these things, that it would be more than
worth it to use a leased line for SLIP access, unless someone can tell
me of some effective workarounds...
Thanks...
Chet

All you need is a little program to detect the need for an outgoing connection, dial up and establish the connection, and then drop it when there is not traffic for some period. It's not hard (I've done it). -- Jon Zeeff (NIC handle JZ) zeeff@b-tech.ann-arbor.mi.us

Leased lines are better than dialup connections; there is no doubt about that. However, they also are significantly expensive, can sometimes be hard to get, and generally require explicit budget justification rather than getting a "free ride" on existing hardware and existing phone bills. -- "I don't *want* to be normal!" | Henry Spencer at U of Toronto Zoology "Not to worry." | henry@zoo.toronto.edu utzoo!henry

In the Bay Area, for example, you can't get a business line with unlimited local dailing - everything is measured rate. For this reason, it will be cheaper to lease a dedicated 9.6KB line if you plan on using for more than a very small amount (like an hour a day or thereabouts). In additione, 56KB ADN ("advanced digital network") circuits are not much more expensive than 9.6KB leased lines, though they are not quite as ubiquitous as 9.6KB lines. Of course, there are other capital costs associated with a leased line connection which are not present when getting "a free ride on existing hardware" (but a "free ride on existing phone bills" is much harder to hide if you have measured service...)

If I "ping" the machine on the other side of the outgoing connection (connection not yet established), does this work too? -- Daniel Huber Tel. +41 31 52 96 64 Ascom Autelca Fax. +41 31 52 53 01 CH-3073 Guemligen email: dhuber@autelca.ascom.ch Switzerland uucp: uunet!mcsun!chx400!hslrswi!aut!dhuber
