Re: Cant bring up network interface
Hello, I dont think the problem is related to releasing the DHCP lease because I have Windows XP, SuSE linux and now FreeBSD installed on the computer. I havent had any problem with Windows/Linux. Here's what I get in dmesg for my network interface: --- sis0: NatSemi DP8381[56] 10/100BaseTX port 0x8c00-0x8cff mem 0xd0008000-0xd0008fff irq 11 at device 18.0 on pci0 sis0: Silicon Revision: DP83816A sis0: Ethernet address: 00:0d:9d:43:e5:b7 miibus0: MII bus on sis0 sis0: watchdog timeout --- As soon as this is logged while booting the Ethernet LED on my broadband modem goes OFF. I tried loading module if_sis0.ko and apm.ko, and the Ethernet LED lights up, but when I loaded these modules at startup (/boot/loader.conf) the LED still goes off. When I run dhclient -v I get the following output: --- Internet Software Consortium DHCP Client V3.0.1rc12 Copyright 1995-2002 Internet Software Consortium. All rights reserved.

Can you point out how I can debug more, and get this solved??? Thanks in advance, --Nikhil.

I havent had any problem with Windows/Linux. Perhaps not, but I think it's related to DHCP. Do you have a lease in /var/db/dhclient.leases? If not - have you perhaps enabled firewall functionality which could block 255.255.255.255? Here's what I get in dmesg for my network interface: --- sis0: NatSemi DP8381[56] 10/100BaseTX port 0x8c00-0x8cff mem 0xd0008000-0xd0008fff irq 11 at device 18.0 on pci0 sis0: Silicon Revision: DP83816A sis0: Ethernet address: 00:0d:9d:43:e5:b7 miibus0: MII bus on sis0 sis0: watchdog timeout Yep, all looks ok there: I have 3 of those all working fine. (5.2.1) Haven't seen 'watchdog timeout' errors though. As soon as this is logged while booting the Ethernet LED on my broadband modem goes OFF. I've never found an LED state particularly informative. Could you make your line length ~76. The google archive seems to quote long lines verbatim, causing horizontal scrolling :( I may be completely wrong, but I think some wrong module is getting loaded, which is causing this problem. Can you point out how I can debug more, and get this solved??? You could use parameters from a SuSe or XP lease to manually config the BSD installation. And then you could test connectivity to the ISP DHCP server. I'm not sure how to test the (main) broadcast address though and that's the one which is used (magically ;)) when an interface has no clue (previous lease) to consult. -- John. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
