[comp.sys.dec] SLIP over terminal servers

doelz@urz.unibas.ch (01/30/91)

We have lots of Macs on 19200 baud lines connected to terminal 
servers (LAT protocol, Decserver 100 to 500). The Macs could 
run tcp/ip if configured, and I want to set up SLIP between 
Macs and Terminal servers so that the Macs can use UNIX resources. 
The need is for XWindows (I know, 19200 is *slow* for X), 
eventually SMTP Mail, telnet, FTP, and lpr. 

IP sites at our place include decstation 5000, convex, silicon graphics, and 
(VMS) vaxes running ip. 


I would like to know whether someone tried this. 
Pointers, Offers, Resouce tips, and all other hints welcome.

I confess that I have been demented enough to run SLIP over LAT, using
a VMS/MultiNet system as the gateway.  It works, though I wouldn't want
to run X over it!

Our configuration has never included Mac SLIP clients, so I can't 
vouch for that.  We have used VMS/MultiNet systems as clients (works
great, supports VJ compression) and a SunOS system (lousy performance.)
In fact, we have even run this topology:

		    public phone line
[vax]-[v.32 modem]---------------------[modem]-[data PBX]-[DECserver]
								| enet
					     (the Internet)---[vax]

and it worked well enough to satisfy a whole convention of electrical
engineers!  (To be sure, not the world's most demanding audience...)

If this appeals to you, drop me a line and I'll send you the gory details.
