Subject: How can I terminate AsyncATalk connection?

Dear netters,

I have recently set up AsyncATalk on my CAP6.0p100 server and my Mac+
with KanjiTalk6.0.7. I successfully connected to CAP server from
serial line and used AUFS volume. (Thanks for authors of AsyncATalk).

The bad thing here was that I could not find any way to terminate the
program 'async' from my Mac+. I read INSTALLATION in the directionry,
only to find the description of how to connect, not how to disconnect.

Could someone tell me how to terminate 'async' from Mac and go back to
shell? Currently, I just turn off my modem and make sure the line is
disconnected.

I am trying to install CAP on our Sun using EtherTalk (NIT) and the 
installation seemed to go fine except I don't know how to get it running.  
I thought that aarpd would automatically generate the correct etalk.local
file.  when I try to run aarpd I get the error message "No ethernet 
interface specified".  What do I have to set up to get it running?  

We have a mixed network with Macs on both LocalTalk and EtherTalk and a 
GatorBox.  What is the "best" configuration for a mixed network IPTalk, 
NIT, or enet?

You might try "ACCT" which is the command that most ftp clients really
send when you send "account".

So you'd send "ACCT <write-password>".

(See also RFC959 and RFC1123 if you really want to become an ftp

Fetch *is* one amazingly good FTP client, though...

I believe Inside AppleTalk indicates that such a situation should not
arise, as any router that comes up on the net should first check to see
if conflicting information currently exists on the net (though it
doesn't say what you should do if you find it). Therefore, I would say
stick with what you've got and log some sort of error if you have a
mechanism to do so. Going with the new info could be a hairy security
issue. This also goes to say that if you come up seed and the info on
the net does not agree, either shut down your interface (which is what
I would want done) or come up non-seed (which I think is icky).
Sending out conflicting RTMP's is just plain wrong (though some router
manufacturers do it).

Blech. I don't think you should be able to.

Trouble getting aufs to work on a subnetted machine - Help!
===========================================================

We have CAP60 pl100 nicely working on our X.X.200 main net, but cannot get
it to work on our shiny new Sun Sparc 600MP, which is on our X.X.202 subnet.
All our Fastpaths are on the 200 net.

"Everything" appears fine: getzones on the latter sees zones; the logs are
clean (including AUFS reporting 'Waiting for session 0 to activate'); atis
checks out fine. However, atlook does not show the local 202 CAP host,
although it does see the CAP hosts on the 200 subnet. Similarly, Mac users
do not see the 202 AUFS service. Also, the 202 machine can see the 200 
Fastpaths; and the Fastpaths can see the 202 machine (by Telnet/ping, at 
least.)

Why?!

We run atalkad to supply the supplementary subnet routing info. (We
*think* it's set up right!) Would this cause the problem? All the CAP
hosts rely on a *single* Fastpath administered by this daemon. This FP is
on the 200 net as well (note: not the 202 one?).

The only difference with this non-working machine is that it is on a
subnet, and all the successfully-working machines & FPs are on the main
net. Please can someone confirm that the atalkad setup is the only thing
possibly wrong? What else could it be?

I don't understand why everything except atlook checks out on the broken CAP
host...

Thanks for any help,

Not quite true...  The University of Toronto is the author of an smtp QuickMail
gateway called BeaverGate.  It is available via anonymous ftp from:

madhaus.utcs.utoronto.ca

It seems to work fine if you are not running mail services on an AppleShare 2.x
server - BeaverGate has an application that needs to run that would compete
with QuickMail Administrator for the single application slot on the server.

Well, that's not entirely true. Check the PhoneNet docs. (And I assume
that the net in question is a twisted-pair system.)

More to the point, no one recommends that you hang 33 devices off one
leg of a passive star (altho Mr. Burns doesn't mention the actual
wired length of the leg itself).

A good rule of thumb to observe: Whatever works, works (I know this is
an anathema to some on this list, but it's Monday morning:-}).

Mine works fine.

One issue to concern yourself with is what the remainder of the passive
star looks like. How many nodes? How much wire? Before we got our
NuvoTech TurboStar, we ran a 7-node passive star, with about 30
devices on it, printing and file serving supported. It worked darn
well (altho I must admit that every time I added a new device, I held
my breath for two days:-}).

So, the bottom line as I see it: Look toward adding some sort of an
active repeater. As you add more devices, you will most likely get to
the point where you need it. Be prepared to rewire the whole darn
thing. Even if you add an active repeater at the centerpoint of the
star, you've still got 30+ devices on one leg. This certainly
qualifies as a no-no (or at least a "shouldn't-shouldn't").

My question should be fairly simple.  When I use the System 7.0
LaserWriter driver to save a rpintout to Postscript, ftp the file to
my UNIX account, and try to print the file, the first page comes out
fine, but starting with the second page, the text is in Courier
instead of the font I had selected (Times, in my example, though I
don't think it matters).  Since Courier makes the lines longer, the
right side of the lines doesn't wind up printing.  Has anyone else
seen this?  Is it an artifict of the original 7.0 LaserWriter driver?
Do I need to use macps to add something to the file?  Any
suggestions/solutions are welcome, either posted to the group or via

I've got a communications facility that uses AppleTalk (some LocalTalk nets
connected via Ethernet), but would like to make real use of the internet.
Anybody got any sample code (either C or Pascal) that illustrates the use
of MacTCP?
I'd appreciate it if you could mail it to me directly!

Thanks,
	Chris
