No IP on Boot
I have installed RHEL 4 U2 AS on a new machine. The problem I am having is that when I boot the machine, I won't get an IP from the router.I have to unplug the cable from the nic or the router, plug it back in, and ifconfig it up. Any ideas why it would do this? For reference:
etc/sysconfig/network-scripts/ifcg-eth0 DEVICE=eth0 BOOTPROTO=dhcp HWADDR=00:30:1B:3E:46:1D ONBOOT=yes TYPE=Ethernet dmesg: eth0: RealTek RTL8139 at 0xb000, 00:30:1b:3e:46:1d, IRQ 10 eth0: Identified 8139 chip type 'RTL-8100B/8139D' eth0: link up, 100Mbps, full-duplex, lpa 0x41E1 eth0: no IPv6 routers present eth0: link up, 100Mbps, full-duplex, lpa 0x41E1 eth0: no IPv6 routers present eth0: link down eth0: link up, 100Mbps, full-duplex, lpa 0x41E1 |
Grep DHCP in /var/log at least. There may be a bunch of reasons, for example incorrect DHCP client version, your host not in the list on dhcp server (I don't know if routers can be this smart). Also you can run 'dhclient eth0' and view output instead of grepping - it'll be some useful information.
