Is it possible to access an AppleShare File Server across the Internet? For example, if two (spatially distant) LocalTalk networks are connected by FastPaths to local Ethernets which, in turn, are connected to Internet, is there a way that each other's zones can be seen and the file servers accessed? There technically seems to be a way if AppleTalk is encapsulated in IP datagrams by the FastPath. Before I spend my time digging into this, I would like to know if it really is theoretically possible, and if so, how would I go about doing it, drawbacks, etc.? Thanks.

The latest version of the GatorBox software (Version 1.5) allows to connect two GatorBoxes together via a IP network. So far, I have not see, and standards or puplished protocols (Cayman are you willing to aid in compatiblity!?) Both GatorBoxes need to be configured to map zones and network numbers correctly. I have not tried this yet, I will be trying this later this month.

Yes this is very workable. You need the following: 1 Both kboxen with their "UDP Side" config set to something reasonable, 2 The "AppleTalk Administrative Daemon" (atalkad" running somewhere, 3 Both kboxen's "administrator" config pointing to this "somewhere", 4 Proper entries in the "atalkatab" file describing the conection. Now where's the documentation? Hmmm. I suggest you fetch a copy of atalkad from somewhere and also a copy of the KIP sources which fully documents the protocols used (in the source code :-) - seriously the docs included do tell you things you need to know. I'd recommend the copy of atalkad in the "multigate" directory on "munnari.oz.au". Most of the documentation is at the top of the "atalkatab" file - there's 8 pages of it describing what's going on. I know because I rewrote/edited most of it.

How it works depends on how fast/clean/repeatable-round-trip your Internet link is. The AppleTalk protocols are a might fussy about these things. If the link is slow you can expect poor performance. Tom Evans (.sig on previous posting)

It's very simple however, and we would be glad to work with anyone who wants to use it. Perhaps we should write up a a simple document. Basically the two gatorboxes are configured as half-routers with a udp "pipe" between them. The "pipe" looks like a phase 2 network, and works just like a network wire (i.e. RTMP's get sent). We just address all the "control" packets (rtmp, zip, etc...) to and from network 0, node 0 as the "pipe" has no network address. The encapsulation is identical to that used by KIP. The source and destination udp port number is alway 910 (unlike KIP). Not very fancy, but it works. We plan to augment the facility, but will use a different udp port number to preserve backward compatabilty. -brad

We are using the GatorBox's internet facility to connect Penn State, Rutgers, and soon U of Rochester. It works quite well, and we have had very few problems with it. I would recommend it over kip if you have the GB's in place. -- Bill Sproule - Networking - Princeton University sproule@Princeton.EDU sproule@pucc.BITNET 609-258-6089
