Defining a static ip in dhclient.conf

[cheesefarmer]

Hi

i'm trying to setup eth0 so that dhcp is tried first, but if a lease cannot be obtained, then to use a static ip for my home network.

The dhclient.conf man page states that this is possible but i cannot work out the options or find an example! Putting the following in /etc/dhclient.conf doesnt produce the desired result:

timeout 30;
alias{
interface "eth0";
fixed-address 192.168.100.10;
subnet-mask 255.255.255.0;
}

Any help would be much appreciated!

Thanks

Chris

I have wlan0 as my default device.

Look at this file: /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=Charlie
GATEWAY=192.168.2.1
BOOTPROTO=static # I added this

And in /etc/sysconfig/network-scripts/ifcfg-wlan0:

# Broadcom Wireless 4311
DEVICE=wlan0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:1A:73:2C:73:A1
ONBOOT=no
DHCP_HOSTNAME=Charlie
IPADDR="192.168.2.103"
NETMASK=255.255.255.0
NETWORK=192.168.2.0
BROADCAST=192.168.2.255

After inserting these files, connecting with encryption was enough. Negotiation went automatically I didn't even had to execute dhclient wlan0...

You should be able to understand this by reading (I think, you seem quite experienced). If you have anymore questions, post it .
