Change from DHCP to Static IP Address in Fedora Core 7

Asked by nathan8 in Linux Administration

Tags: Redhat, Fedora Core 7

I installed Fedora Core 7 several months ago. At the time, it was setup to take a DHCP address.  Now, I need to assign a static IP address to the machine.

This seemed easy, as there were many examples online.  However, none of them seem to work on this particular machine.  I need to do this on the command line, or using Webmin.

Here is my initial ifconfig output:
eth0      Link encap:Ethernet  HWaddr 00:0D:56:27:C5:D4
          inet addr:192.168.2.174  Bcast:192.168.255.255  Mask:255.255.0.0
          inet6 addr: fe80::20d:56ff:fe27:c5d4/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:837 errors:0 dropped:0 overruns:0 frame:0
          TX packets:113 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:66399 (64.8 KiB)  TX bytes:24590 (24.0 KiB)
          Base address:0xdf40 Memory:feae0000-feb00000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:11962 errors:0 dropped:0 overruns:0 frame:0
          TX packets:11962 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:94217656 (89.8 MiB)  TX bytes:94217656 (89.8 MiB)


Here are the things I tried.

1.  On the command line:  setup
    1a.  In the setup utility, I chose Network Configuration.
    1b.  DHCP: Unchecked
    1c.  Static IP:  192.168.1.150
    1d.  Netmask:  255.255.0.0
    1e.  Default Gateway IP:  192.168.0.2

2.  I saved this.
3.  Here is the output of /etc/sysconfig/network-scripts/ifcfg-eth0
PEERDNS=yes
HWADDR=00:0d:56:27:c5:d4
TYPE=Ethernet
IPV6INIT=no
DEVICE=eth0
MTU=1500
NETMASK=255.255.0.0
BROADCAST=192.168.255.255
IPADDR=192.168.1.150
NETWORK=192.168.0.0
USERCTL=no
ONBOOT=yes
GATEWAY=192.168.0.2

4.  Next, I restarted networking:  /etc/init.d/network restart

5.  ifconfig has not changed.

6.  Next, just to try, I restarted the Linux box with shutdown -r now

7.  ifconfig has not changed.  It still shows the old DHCP address for eth0.

8.  Someone suggested that I modify /etc/sysconfig/network-scripts/ifcfg-eth0 manually, but, as you can see above, it looks correct.

9.  Next, I tried system-config-network, which is the same network configuration found in setup.  No luck.

So, what am I doing wrong, or what has not yet been done?  Thanks.
