Problems with 2 ISDN cards in 2 machines on network
Hi all, maybe a bit off topic, but I'll take my chances. I have a network where there is a SuSE 7.1 file server, a SuSE7.0 firewall/gateway. I'm using ADSL for my internet connection through the gateway. The fileserver also has an old Teles 16.3 ISDN card installed which, since ADSL, only takes care of my telephone answering machine (vbox) and logging. And I have a Win98 system that I use for developping for customers. The Win98 also has a (newer) Dynalink ISDN card. This is used mainly to be able to connect to one of my major customers server. My complete network config can be found on: http://www.jota.nl/netwsch.htm (graphical) and http://www.jota.nl/jota.htm (text) A few weeks ago I reinstalled/configured the Win98 system. And now for some reason I can't get it's ISDN card to work if the Fileserver is also connected to the ISDN line. When I unhook the fileservers ISDN card (and reboot) everything is fine. In Win98 the Dynalink Linetester keeps giving Errors on different channels when both are hooked up, so I suppose there is some kind of interference. Could it be a faulty card? Can anybody point me to a direction where I might find the answer to the problem? I never had this problem before. Both cards and both machines have always been working when both were connected. Any help will be much appreciated. keep up the good work, Jeroen

Did you change a cable or the cabling at all ? Normaly this behaviour is a sign of a crossed pair in one cable (or connection box). ISDN must connect 1:1 on all TE if not syncronisation is lost and the TE's shows errors, but each work, if the others are disconnected. -- Karsten Keil SuSE Labs ISDN development

IMHO i'm missing your TCP/IP and routing configuration. My be your are using the same IP-address on two different cards? Are you allowed from your ISP to dailin ttwice at the same time? cu Gerald
