I have a headless Centos server that I've configured with a static IP address. I've disabled Network Manager, avahi-daemon etc. Whenever I restart the network it just jumps to 10.155.90.100 instead of the required 10.155.90.61 with no explanation:
Here is my ifcfg-eth0:
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) DEVICE=eth0 BOOTPROTO=static ONBOOT=yes #HWADDR=00:50:56:b0:5a:57 IPADDR=10.155.90.61 NETMASK=255.255.255.0 GATEWAY=10.155.90.1 TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes NM_CONTROLLED=no
It seems to be running DHCP anyway. I cant seem to get a more detailed log than this in /var/log/messges:
Jul 11 12:50:33 NET: /sbin/dhclient-script : updated /etc/resolv.conf Jul 11 12:50:34 kernel: 8021q: adding VLAN 0 to HW filter on device eth0 Jul 11 12:50:34 kernel: ADDRCONF(NETDEV_UP): eth0: link is not ready Jul 11 12:50:34 kernel: e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None Jul 11 12:50:34 kernel: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready Jul 11 12:50:36 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67 (xid=0x39edae98) Jul 11 12:50:36 dhclient: DHCPACK from 10.155.50.20 (xid=0x39edae98) Jul 11 12:50:36 NET: /sbin/dhclient-script : updated /etc/resolv.conf Jul 11 12:50:36 dhclient: bound to 10.155.90.100 -- renewal in 255205 seconds.
How can I turn off DHCP and stop the server jumping for the wrong IP?
