We need some advice on a couple of issues.  Any comments or information
would be greatly appreciated.

   Location 1: Sun 4/390s running a Sybase server
 
   Locations 2,3,4,5: Small Sun networks across the country

What we hope to accomplish is the following:

     Transparent client access from locations 2-5 to the server at 
     location 1 (i.e. ability to use Sybase as if we were one local net),
     as well as telnet, etc.

At our disposal is an SNA network connecting all the sites. We would prefer
to use it but if there are other cost effective ways we will certainly 
consider them.  The real questions here are whether TCP/IP over SNA is 
possible/feasible/tolerable and whether Sybase DB-library functions well
over an internet

A side issue involves SNA on Sun. Can we support a user (either logged in
via telnet to the server or directly from locations 2-5) who wants a 
terminal session to an IBM host on the SNA network and can we support 
application to application from the Sun server to the IBM host.

Thanks in advance for those copious, informative replies. Please reply by
mail and include a telephone number if you would'nt mind a phone call. Also,
I realize that these topics may be fairly standard to some but please, don't
let my ignorance dissuade you from replying.

                   Thanks,
                   Andrew
