Today I compiled the kernel with the CONFIG_IP_PNP and CONFIG_ROOT_NFS and tried to boot it remotely. It boots, printing the following: IP-Config: Got DHCP answer from 192.168.10.10, my address is 192.168.10.111 IP-Config: Complete: device=eth0,addr=192.168.10.111,mask=255.255.255.0,gw=192.168.10.1, host=student11,domain=c201,nis-domain=(none), bootserver=192.168.10.10, rootserver=192.168.10.10,rootpath= Kernel command line: root=/dev/nfs ip=dhcp The infrastructure is as follows: tftp & nfs Linux server (no isc-dhcpd installed) - address 192.168.10.10 DNS, Gateway AND DHCP server (FreeBSD) - 192.168.10.1 i.e. the kernel obtains all the network parameters correctly from 192.168.10.1, but reports that the DHCP response has been received from 192.168.10.10. This is all coded at lines 1156 and 1364-1373 of the file /usr/src/linux/net/ipv4/ipconfig.c If I had some more time, I would be glad to study ipconfig.c in detail and probably fix this bug, but I need to get on with my A-Level studies. Steps to reproduce: 1.Compile a kernel that is able to be booted remotely 2. Make one machine DHCP server (say, IP 10.1.1.1), and another machine - tftp+nfs server (where the rootfs is mounted, and kernel is taken from - say, 10.1.1.2) 3. Try to boot the kernel - it reports that network configuration parameters have been obtained using DHCP from 10.1.1.2, rather than from the real DHCP server, 10.1.1.1, although in fact the settings are obtained from 10.1.1.1. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
