CAP should handle this already - no mods needed. The first thing to
understand is what CAP uses broadcast IP for. When you open your
Chooser on a Mac, select the zone that contains the CAP host and
then look for something that it has (print server or file server),
the IPTalk Gateway that handles the AppleTalk to IPTalk has to
ensure that the NBP LookUp gets to all devices in that zone (read
CAP hosts). If a line with a flag like "N1" is in atalkatab for that
network, it will use the IP address with one byte of all-ones
appended - it will send a directed-IP-broadcast, and hopefully all
hosts on that network will receive and respond.

In your case I'd recommend putting an "H" line in there (instead of
"N"). This means that this designated IP host (the IP address after
the "H") will get the NBP LkUp send to a "rebroadcast" port - it is
then its responsibility to rebroadcast to all hosts on that subnet.
Note subnet here means all hosts with the same first-three-bytes -
this will probably span multiple of your 5-bit subnets.

The "rebroadcast server" can either be an IPTalk Gateway that is in
that subnet (and thus is configured with the proper broadcast
address to use), OR it can be "atalkrd" on that host. As a
command-line option you give it a list of host IP addresses to send
the NBP LkUp to.

This is the first message I've posted on Internat, so bear with me.

I'm interested in connecting a Mac and a PC (I have the PC but haven't bought
the Mac yet) so that I can easily transfer files back and forth.

My understanding is that all Macs have an appletalk networking connector.  Can
I get an Appletalk card to go in a PC?  If so, who sells such a thing?  How
well does it work?  I know Appletalk is pretty slow, but does the netword
software on the PC side hog memory and conflict with lots of stuff, or work
pretty nicely.

Can one connect multiple things to a Mac via appletalk?  Can one (for example)
connect both a PC and a printer?

I know perfectly well that Macs and PCs can share an Ethernet network.  I just
need something much cheaper.

Any help will be appreciated.

This is something that I have come across here at the SSC. In the library
there are four big FMP datafiles in use. If they are not closed down
they come up the same way. According to the folks at Claris this is
because FMP flags the file as open and makes it to where no other application
can do anything (include passive read) to it. So the senario is that the
backup program (any backup program) gets the directory entry but no data...
wala...a zero length file. So its not really a backup program issue but a
FMP issue. One workaround....do your backup through an apple event type
program (Frontier or QuickKeys) and force a close of the Filemaker
Application before the backup program runs.

What a rotten way to find out about FMP backup strangeness. Good luck on
your data recovery.

So I guess one must close the databases if correct backup is expected -- and
it appears that NO backup program will work any better.  Of course, if I
put the files on Unix then there will be no trouble -- but I have a hunch
that FMP won't necessarily work correctly in that case.  On to 4D+Oracle...

It depends on how you've set up the FastPath. You can set it up to
dynamically assign addresses or to do static addressing. We use static
addressing.

I am running CAP pl126 with EtherTalk Phase 2 and native
EtherTalk on a Sun SPARC with SunOS 4.1.1 Rev. B, so I am
not sure whether the following will apply to you.

According to the Sun "System and Network Administration"
manual, chapter 12 "Maintaining Printers and Print Servers",
the permissions for a printer device must be set as follows
(assuming printer device /dev/ttya) --

	# ls -lg /dev/ttya
	crw-rw----  1 daemon  daemon  12,  0  Oct 21 11:57 /dev/ttya

Since CAP is really writing to /dev/nit, I found it necessary
to change the permissions of /dev/nit similarly to get
printing to work, that is --

	# ls -lg /dev/nit
	crw-rw----  1 root    daemon  37,  40 Feb 12  1992 /dev/nit

Hope this helps.

Hi!

I am having some problems moving files between vanilla UNIX direc-
tories and CAP volumes that I imagine someone of you has solved
before.


1.  The same Unix machine (a SUN SparcStation) that acts as the CAP
    server is also the mail server.  A number of users would like to
    be able to copy email into their CAP volume and have it appear
    as an MS WORD text file to the Macintosh.  Currently, I have a
    shell script that copies the file and runs u2m (a utility included
    in the CAP distribution I installed).  The mail appears with a
    UNIX icon, and MS WORD must be brought up before an attempt is
    made to read the file.  Users would like to click on the document
    as they do for ordinary MS WORD files.

    Is there any program I can use to properly update the .resource,
    .finderinfo, et cetera, and set the file type and creator fields?

2.  Some documents that are originated on PCs running WordPerfect are 
    FTP'd to the CAP host.  We then FTP the document to the Macintosh
    and copy it to the CAP volume from the Mac prior to converting it
    to MS WORD.

    It seems a bit extreme to have to move the document from the UNIX
    to the Mac and then back to the UNIX in CAP.  Is there a utility
    that will accomplish the same thing as FTP without the Macintosh
    having to serve as the middleperson?  

It may be that the answer to both question is really the same, which
would be nice, but any suggestions would be greatly appreciated.

I have a PhoneNet/AppleTalk net with several laser printers that is onnected

not have anything equivalent to GatorPrint.  Thus the question to this group.
What are my best options to provide printing from ethernet-based machines

I gleaned this from Inside AppleTalk, this newsgroup, and experience with
our network.  For example, our "Smith Lab" zone is in the zone lists on
several networks ("cables"): One is LocalTalk, one is the main Ethernet,
and another is a Novell file server's internal net.  The same goes for
our zones "EEAP" and "WSOM", though I think EEAP is only on LocalTalk and
Ethernet, but not a server internal net.

One person pointed out that "span" might be the wrong term, though I think
the meaning is clear: The same zone name can be assigned to more than one
network number range, on different subsections of the network.

BTW, I used the term "cable" because I couldn't think of a better term.
"Subnet" is the IP term for what I want.  Maybe "segment"?

One source for the single-zone limit for LocalTalk is NetWare for Macintosh:
"A nonextended network is NOT capable of supporting the Phase 2 addressing
extensions of a netork range and zone list." [1]

I hope this helps.

Greetings,

I need some advice and info on upgrading a network to multiple phase2
zones. Currently I administer a network which has only one phase2 zone and
one phase1 zone, with a number of FasPaths, Gatorboxes, Ciscos, etc on the
backbone. What I need is feedback on the following scenerio.

Assume that all net devices agree on a range of 50 zone numers, say 1-50.
Do all 50 zones have to be named at the time the net is configured? What we
would like to do is assign 10 departments with control of 5 numbers each.
1-5 would be controlled by dept1, 6-10 by dept2, etc. Currently most depts
dont need all five zones at this time, so some zone numbers would be left
unused and presumably unnamed until some later date. Is this possible? and
what would we have to do to impliment it? 

I would appreciate communicating with someone who has upgraded large
networks to phase2 to see how others have done it.

Thanks,
Tom

This sounds like a well-known incompatibility between MacTCP and the
latest Appletalk software.  The symptom is that the MacTCP control panel
can't see the localtalk interface.  It is fixed in MacTCP version 1.1.1.

I have a System 7 Mac LCII running MacTCP 1.1 successfully across an Ethertalk

When I try to set up MacTCP to speak over Localtalk (Network is set to 
Localtalk Built-In), Telnet can't find any DNS servers and Eudora bombs. 

Should my 'Gateway' entry for MacTCP now point to the Fastpath's IP number 
(which one?) or the DNS?

Should my IP number now be set dynamically instead of manually? (No RARP here).

Should I be able to run these programs via Localtalk at all?

Sorry to bother, but all I can locate is CAP 5.0.  Everyone talks
about CAP 6.0.  

Thanks,
