This probably isn't the appropriate list for this question, but I'm not
sure where else to ask it.  If someone knows of a network comm server
mailing list, let me know

If you buy a terminal server with 16 ports for about $2200-$2500, which
seems to be the current ballpark figure, that's closer to $140/port.
If you know something I don't about terminal server prices, let me know!

My question is what you do about accounting when you want to provide
SLIP/PPP access via the terminal server (as opposed to using a daemon
on a unix host)?  The information I have so far says that the Xylogics
term server with authentication software is considerably more expensive
than $150/port, so how do you do it with a "dumb" term server?  If I
understand the literature correctly, you can password-protect ports,
but there's no way to authenticate users (match their user-id up with a
db on a unix host for billing purposes).  What's to stop random people
on the street from dialing in to your term server, establishing a SLIP
connection, and wandering off to the net, completely bypassing your
local hosts and your billing facilities?

One alternative to this might be to have users telnet to a unix box and
run a SLIP process there over the telnet connection from the term server
to the unix box.  That seems like it would be pretty painful (running
a TCP/IP stack on top of another TCP/IP stack).

Am I missing something?  Should I be talking to different vendors?
