From Bugzilla Helper: User-Agent: Mozilla/4.78 [de] (X11; U; Linux 2.4.9-13 i686) Description of problem: ifconfig prints strange results for isdn devices. Every isdn devices is listed twice. The first time including RX/TX packets and bytes and the second without these statistics. I have attached the output of the ifconfig, route and ip commands Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. setup an isdn device 2. see the output from "ifconfig" 3. Additional info:

With 12 interfaces this sounds like a multiport ISDN card. I suspect it might be a problem in the driver as this card probably hasn't had the extensive public tests of the popular AVM Fritz or Teles cards. And i am pretty sure we don't have such a card to test/verify this problem, so i'd recommend to ask your card vendor if this might be a know problem to them and if there are updated drivers. You can also always use the latest errata kernels, they often contain never versions of drivers as well. Interessting would be the output of /proc/net/dev on that machine as well... Read ya, Phil
This is not a multiport card at all. It's a normal AVM FritzCard PCI. I use the 12 connections for remote administration purposes. So it is not necessary for me to have 12 simultaneous connections, I only need the 12 logical connections. I'm always running the latest errata kernels (now 2.4.9-21). I will attach the output of /proc/net/dev as requested by you.

How did you set up the 12 logical interfaces? Using ip or ifconfig? Another thing would be to try to set up other logical interfaces for e.g. your ethernet interface and see if the same thing happens there. The we could be sure it's not a ISDN only problem but maybe something generally broken for logical interfaces in ifconfig. Read ya, Phil PS: As a general rule: We indirectly deprecate the use of ifconfig as ip is the actively maintained successor of it. Nonetheless, ifconfig shouldn't output all your isdn cards twice :-)
The interfaces are setup using the normal Red Hat init scripts. I just put the interface descriptions in /etc/sysconfig/networking/devices and after system boot everything is working fine besides the missing static routes for the ISDN interfaces (reported as another bug) and the double entries in the ifconfig output. What do you mean by logical interfaces for ethernet? Aliases? ISDN and ethernet are handled completely different by the kernel in terms of physical/logical connections.
This bug should now be fixed in the latest rawhide versions of net-tools. Please verify. Thanks, Read ya, Phil
Hard to test as I don't have any RHL 7.2 system with ISDN anymore. I can't reproduce the problem on RHL 9 or later.
OK, closing the bug as current release then. :-) Read ya, Phil
