I need a list of ANNEXes on the internet (if you don't know what an
annex is, see below). Over the next year, I'll be traveling to San
Antonio, Chicago, and possibly other cities, and would like to be able
to log into UT-Arlington without a long-distance phone bill.
On most regional networks these days, it is against policy to have an
Annex, Cisco, or other terminal server that can reach hosts that you
don't own. This stems from security problems in the past. If you're
going to be in one city for an extended length of time, you might want
to talk to someone in that city, and see if they can be persuaded to
provide you with a guest account on one of their machines.
My list of annexes that is a year-old printout, and is buried under a
ton of other stuff. If I find it I'll merge it with everything I get
from the net & summarize to the net.
Please, don't. True, those terminal servers are a valuable resource,
but you shouldn't go publishing them to the whole Internet, or they
will almost certainly get exploited by some cretin and get address
restriction turned on. You would be doing anyone who was benignly
using these machines to legitimately access other hosts on the
Internet a disservice by bringing this about.
What to do then? If you can live with 1200 baud and you're eligible
(or have a real good friend who is :-)), you might want to try for a
MILnet TAC card. You also might want to consider a PC Pursuit account
(if outdial service is available for your home town). If your need is
legitimate enough to get your organization to spend the bucks, you
could get X.25 service from a commercial X.25 provider (like Telenet,
Tymnet, or CompuServe's communications department). Otherwise, I'm
afraid you'll have to bite the bullet and pay the long distance. Or
hope that your printout still contains some valid info :-).

David -- Chances are a good number of Encore Annexes (and similar products, such as Cisco's terminal servers) are configured in such a way that you can't use them to get to arbitrary Internet hosts. For example, the UCLA CS Department has all its dialup lines connected to a Cisco server (similar to the Encore Annex) -- but we've set it up so that you can only log in to UCLA CS Department machines from it. If you try connecting to a non-UCLA machine from our Cisco box, you'll get a "connection not permitted" message. In fact, it was my understanding that owners of dialup-line servers on the Internet were expected/required to restrict them to access local hosts only, to impede "hacker" activity. (Does anyone else on the Name- droppers list have more specific info on this?)

hi all: I thought one had to have some sort of permission or authorization to use the Internet? As I recall, the U of Md recently disallowed anonymous Telnet from their dial-in modem bank to non-UMD sites because of complaints. Bob Enger

UUNET also provides 'TAC' access - dial a local access number or an 800 number and get telnet access back to your home system. Contact info@uunet.uu.net for more information & rates. --asp@uunet.uu.net (Andrew Partan)
