[unix-pc.uucp] UNIXPC uucp problem

becker@ziebmef.uucp (Bruce Becker) (06/28/88)

I've been having a problem with my 7300/3b1, in that it won't
receive uucp logins from anyone at all (BAD LOGIN/MACHINE NAME), but I
can connect to any machine by dial-out... I don't understand why...
If any 3b1 users have had this problem, please email some suggestions
to me...

Thanks, Bruce Becker

 Bruce and I managed to track down and solve (sort of) this problem;
it was apparently a bad USERFILE. However, I looked at it and it
looked fine, and very similar to the one I use here. Are there any
known limitations of the 3.51 USERFILE? 

 Also, are there any guides to 'troubleshooting UUCP connections'?
I've got quite good at finding problems (having stubbed my toes on
most of them by now :-(), but there are undoubtedly other traps just
lurking out there just waiting for me. I have the Nutshell handbook
_Managing UUCP and USENET_ and have found it quite valuable; is there
anything else people would recommend? Better yet, is there some
documentation on the bugs ... ahem, idiosyncracies of the stock 3B1
uucp?

 While I'm here ... Hint #38: Have an external modem you need to dial
with a chat script (to, say, dial something with pulse and then switch
to tone-dialing to get through a PBX), but don't want to always assert
CD on the modem (uucico requires DCD before it will go into the chat
script on a direct connection)? Just define a really dumb modem that
does nothing in modemcap, and point the appropriate L-devices entry at
it.  Unfortunately, this means you have to dial via chat scripts for
all connections over that modem at that speed, but it's better than
nothing...

One.  If you add your 101st entry, it'll "die."

Oh, it's even better than that.  No system will ever be able to make a
UUCP connection with your machine until you bring to to 100 entries or
under.  Neat?

The 3b1 has a goofy OBM.  (Also, please refer to some immediately
previous replies to other messages).

Asides from handshaking an OBM connection and then not knowing what to
do from there, it's also something that is apparently out of spec from
certain areas.  Some modems, including Telebit's under certain
connections will always hang up after attempting to establish a
connection with the given carrier.  The "unusual" thing about it also,
is that if you dial _out_ using the OBM into one of these modems, the
same connection will be rejected as well.


Otherwise, the 3b1 generally operates similarly or as well as other
System V machines/implementations (not taking the bug list into
account, of course :-)
