Hi If my memory serves me correct this was covered in the last month on this group but I am unable to find it in the archives. I have two industrial single board computers with two onboard LAN cards each. Both are running SuSE 9.3 One machine is assigned a static IP (192.168.100.102) using yast. When entering the IP yast tells me that it detected a duplicate IP address. The IP is not used on our network and even with the flylead plugged out I still get the message. Yast gives me the option of continuing even though it believes the IP is duplicate. I saved the settings, quit yast and ran ifconfig. The interface didn’t show. I then ran: # ifconfig eth0 192.168.100.102 SIOCSIFFLAGS: Resource temporarily unavailable # ifup eth0 eth0 device: Intel Corporation 82801BA/BAM/CA/CAM Ethernet Controller (rev 03) eth0 configuration: eth-id-... SIOCSIFFLAGS: Resource temporarily unavailable ERROR: Cannot enable interface eth0. ERROR: interface eth0 is not up /etc/sysconfig/network/ifcfg-eth-id-... contains the correct configuration for this card. I have disabled the second NIC and it still has the same problem. The other machine is working without a problem. Any ideas? Albert -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
