Frequently asked Questions on successfully running NIX/Gate
(Compiled by user submissions to the author and beta testers)
Last updated: 20 January 1994
Q) If a user hangs up while in the middle of a UNIX session, what happens?
A) Well, NIX/Gate will recognize the fact that the connection has been lost,
and will hand control back to your BBS to allow for proper logoff
procedures to be followed. At this point, your UNIX shell is still
active, and currently, there is no way to correct it. That is, unless
you configure your UNIX system to respawn the getty for the port. This
is usually not a problem under most UNIX implementations (AIX and XENIX
come to mind), but unfortunately, since we are not actually "connecting"
(i.e. raising DTR), this may be a bit of a problem. We are open to
suggestions on how to handle this, but for now, just make sure to let
your users know how to log off properly!
Q) Why can't I see what the user is doing on the local console? How about a
log file, pal?
A) Due to the fact that under certain terminal emulations, "speed" is of the
essence, we found that performance suffered when "snoop" mode was enabled
for sysop monitoring or logging was enabled. We are working on it,
though...
Q) I am using Coherent as my UNIX system, and the ANSI terminal emulation is
atrocious when dialing in from remote! Any suggestions?
A) The best configuration to use with Coherent is "unixpc" on the Coherent
side, and ANSI emulation on the remote end.
export TERM=unixpc
Place the above line in your profile or startup script.
Q) Can I perform file transfers through the gateway?
A) Yes. This has been tested using several protocols, including X, Y, and
ZModem. We used Forsberg's RZ/SZ suite on the UNIX side, and had no
problems with any standard terminal implementation of the above. Note
that your mileage may vary with this, as NIX/Gate was not designed to be
a file transfer engine. If it works for you, great, if not, well, FWIW
we are looking into making this smoother.
Helpful Tip: Set the BREAK OUT key to zero (0). In essence, this
prevents the user from returning to BFE, but you probably wouldn't do
too many file transfers with a valid break key (for obvious reasons).
We are open to suggestions on this one.
Q) Why can't I get NIX/Gate to run in local mode, so that I can connect to
the UNIX system as well as my users?
A) Because NIX/Gate is not a local terminal-emulator, but rather a product
which is geared toward gating serial connections. Use Procomm or an
equivalent terminal package to set up your local terminals. It's much
easier...
