There is one message totalling 21 lines in this issue. Topics of the day: 1. Dial-Back Security

Dear Everybody, Would anybody tell us how the Dial-back security can be achieved in PPP mode, when the client side is Windows 95. We know the Gold Clinet is not supporting Windows 95. Do the Win 95 Dialer support this with the NetServer? What we should do to configurated for both side? We have no problem in configurating the Quad Modem for dial-back, but once the Quad Modem call-back, the NetServer won't assign any IP address, or the Win 95 Dialer won't answer. Any other TCPIP dialer that support dial-back security? Pls also advise.

There is one message totalling 39 lines in this issue. Topics of the day: 1. Anyone seen this?

We use Cisco 2511s with U.S. Robotics Courier modems. We use them strictly for terminal emulation, ppp and slip. Dial out only. What we've seen happening lately is that certain lines will get hung. Some have symptoms some don't. The ones that do when you do the command "finger who@comm_server_name" will return a line such as "3 tty 3" with nothing else after it. Normally a line is "3 tty 3 userid syr.edu 0" where syr.edu would be where someone is connecting to and 0 is the idle time of the connection. Also when you look at the modem there is no DTR present. The other is a case where the modem just seems to get in a weird state and doesn't answer. If you have auto response it will recognize (usually the ring-no-answer) situation but you need to do a hardware reset on the NIC associated with that line (on the entire module, not just the one line). If anyone has seen this or knows any reasons for it I would appreciate any input.

We use a mix of couriers and sportsters on our 2511. The init string I used for the couriers is AT&F1 AT&K3S10=30S13=1S32=6S2=128TE0Q1X3&W and also don't forget to set the dip switches like this: 1,2,3 - OFF 4 ON 5,6,7 OFF 8,9 ON 10 OFF The important thing above is ATS13=1 which tells the courier to reset itself when the line is hung up. I had some problems before I did this because sometimes the modems were left in a weird state after a connect. Now they reset themselves everytime and everything works just fine. > I'd like to compare the configurations you use in your Comm Servers and > what you use with the modems.

Absolutely no special wiring. Just connect the cisco-supplied 25-pin connectors to the modems and off you go. > We have cases where certain lines will get hung, some have a symptom and > some don't. I had simmilar problems back when I was using IOS 11.0(4). Then I upgraded to 11.0(11) and the problems disappeared. -- Blaz Zupan, blaz.zupan@medinet.si, http://www.medinet.si/~blaz Medinet d.o.o., Linhartova 21, 2000 Maribor, Slovenia From POP3server Fri Nov 14 20:33:41 GMT 1996 Return-Path: dduncan@gloria.cord.edu Received: from syr.edu (syr.edu [128.230.1.49]) by mailbox.syr.edu (8.7.5/8.7.3) with ESMTP id PAA26626 for <rjkopp@mailbox.syr.edu>; Thu, 14 Nov 1996 15:22:51 -0500 (EST) Received: from gloria.cord.edu by syr.edu (8.7.5/CNS) id PAA12590; Thu, 14 Nov 1996 15:24:50 -0500 (EST) Received: from gloria.cord.edu (localhost [127.0.0.1]) by gloria.cord.edu (8.6.9/8.6.5) with ESMTP id OAA04422; Thu, 14 Nov 1996 14:32:04 -0600 Message-Id: <199611142032.OAA04422@gloria.cord.edu> cc: dduncan@cord.edu

Ray: I have three 2511 access servers I put in this past summer for dial-in access to our campus network. I have one US Robotics MP/16 modem rack and 32 external Zyxel 28.8 modems. The modems in the US Robitics rack are the same as Courier modems, just different packaging. I was also seeing lines that hung up as you describe. Also, PPP connections would get disconnected at random times. I had a case open with Cisco Tech Support for a month, trying different things that they suggested without coming to a solution. Finally they had me upgrade the IOS to 11.0(11). I was running 11.0(5) which is what was installed on the 2511's when I bought them last June. That has fixed the problems. They have been rock-solid since the upgrade. No disconnected PPP sessions, no hung lines. Of course now I've got students that dial-up, run PPP, and stay connected for days at a time. But that's another problem :-) --Dennis Dennis Duncan dduncan@cord.edu Network Manager dduncan@netcom.com Concordia College http://www.cord.edu/faculty/dduncan Moorhead, MN 56562 Ph: 218-299-4192 FAX: 218-299-4308 From POP3server Sat Dec 13 18:40:25 GMT 1996 Return-Path: RFougnier@hankisonintl.com Received: from external.stucki.com (stucki.com [206.181.95.194]) by mailbox.syr.edu (8.7.5/8.7.3) with SMTP id NAA26846 for <rjkopp@mailbox.syr.edu>; Fri, 13 Dec 1996 13:13:49 -0500 (EST) Received: from stu-nt1.stucki.com ([192.168.1.201]) by external.stucki.com via smtpd (for mailbox.syr.edu [128.230.1.5]) with SMTP; 13 Dec 1996 18:12:31 UT Received: by stu-nt1.stucki.com with SMTP (Microsoft Exchange Server Internet Mail Connector Version 4.0.993.5) id <01BBE8F7.B73C7760@stu-nt1.stucki.com>; Fri, 13 Dec 1996 13:15:31 -0500 Message-ID: <c=US%a=_%p=HANSEN?LAND%l=ARD-NT1-961213181248Z-579@stu-nt1.stucki.com>
