Pass-Through Routing

I happen to have been with Hubert Lipinski when we invented HUBPASS for CompuServe at the last (ever) cc:Mail Interchange conference in San Francisco. CompuServe wanted to give all subscribers the same PO name to simplify addressing, installation, support, and maintenance.

To meet the customer requirement the Router at the hub PO would have to determine the user's home PO. Cutting through the red tape, Hubert went ahead and added the feature to Router enabling CompuServe to move ahead. Originally, it was undocumented.

Normally the Router gets the user's home PO name from the Mobile handshake and, if it's not the hub name, executes the Remote Call Through sequence immediately by looking up the address of the user's home PO in the directory and executing a Type I connection.

HUBPASS, on the other hand, allows all users to specify the hub PO name as their home PO name in the Mobile configuration. The Router with HUBPASS finds the user name in the directory first, then finds their PO name, and then executes the normal Remote Call Through sequence.

To answer your question, no, I don't recommend using HUBPASS for ordinary cc:Mail systems, as compared with an e-mail service provider. For systems with only 5,000-10,000 users (under 50 POs), it's actually easier to troubleshoot and maintain using full and explicit cc:Mail addressing in conjunction with directory synchronization. Arguably, this is personal preference but consider some of the implications.

For example, part-time Mobile users may know their home PO name and could be confused if their address in Mobile was the name of the hub instead. Similarly, your help desk personnel have to understand HUBPASS in addition to Remote Call Through to support Mobile users in the field. In fact, addressing by user name is valid, but if you use HUBPASS in an ordinary cc:Mail system, it will become known to users that they can have multiple addresses, e.g. "John Valentine AT PO1" and "John Valentine AT HUB."

My advice: Just use the products the way they were designed for small systems unless your system actually is very large. It doesn't pay to get fancy when the product will work just fine out of the box.

Hi Ron,

Hope I'm not out of line sending this to you. Your advice on the ccmail-l list has been helpful and I wanted to see if I could get an opinion from you. I especially appreciate any techinical insight into the workings of cc:Mail as I feel fairly competent when it comes to supporting/working with the product. (I seem to recall meeting you at a cc:Mail bay area users group meeting, but that would have been a couple of years ago.)

Do you recommend using the HUBPASS parameter for mobile dialins? At one of our sites we don't use it, so in mobile the user's home address is their subordinate home po. At another site the parameter is in use, so the mobile home address is the hub, even though their actual home po is actually a subordinate to the hub.

I've gotten differing opinions from various cc:Mail reps about use of this parameter. Any insight you can provide is greatly appreciated!

Many thanks in advance.

Dan,

In theory all you need is a drive mapping to PO2. In fact, you should not do this over WAN links. However, you can get away with it if the pipes are clean and fast enough. If the pipes are dirty and slow it will be your worst nightmare--corruptions, connect problems, and all.

Good luck!

Ron

I have a user whose home post office is PO2, which is subordinate to PO1. He isa user who splits his time between mobile and local use. Our dial-in router (NTRouter 6) resides on PO1. PO2 and PO1 are separated by a WAN link, so performance is unacceptably slow if he is a "local" user on PO1. Is there a way to enable him to dial in to PO1, send and receive messages, while PO2 remains his home post office?

PO2 (Router TCPIP)-----------WAN Link-----------(Router TCPIP)PO1(Router Dialin)----------Remote Users

Thanks,

Dan
