Re:Configuring networking in Red Hat 7.3
There is the easy way ,the not so easy way, and the hard way :
1: The easy way....as the root user type 'setup' then go to network configuration ,uncheck dhcp and fill in the blanks
.
2: The not so easy way cd to /etc/sysconfig/ [as root] vi network and if blank add the lines...
NETWORKING=yes
HOSTNAME=robyg.donman.com
GATEWAY=192.168.0.1 [change this]
GATEWAYDEV=eth0 [if you have more than one eth dev configured]
then cd to network-scripts and vi the eth dev you want to use (eg eth0..ifcfg-eth0) and add this:
DEVICE=eth0
BOOTPROTO=static
IPADDR=robyg.donman.com
BROADCAST=192.168.1.255
NETMASK=255.255.255.255
NETWORK=192.168.0.0
ONBOOT=yes
Then in your /etc host file add :
192.168.0.10 robyg.donman.com robyg
Then run /etc/init.d/network start .
This way to change your IP after you only vi /etc/hosts and change the ip for robyg.donman.com.
Redhat 7.3 may have also added the directive IPNAME however using a FQDN in ifcfg-eth0 for the IPADDR with a corresponding entry in /etc hosts is enough.
3:The hard way....with no interfaces configured type the following :
ifconfig [interface_name] inet [ipaddress] netmask [255.255.x.x] broadcast [x.x.x.255]
this was all in on line (just incase a wordwrap happened here) check that all looks good with `ifconfig -a`
now this is not all set up the gateway(default route) as such :
route add -net [192.168.1.0] netmask [255.255.255.255] gw 192.168.1.254 dev ethx
now type route -n
if all looks good ping www.cnn.com now (a) make a startup script and add all the ifconfig and route settings there or (b) use redhats network startup script create a /etc/sysconfig/static-routes file with the route configs or (c) just fill out the ifcfg-ethx file and network file with all this info just as in (2) just that (3) with no interfaces configured allows for immediate use of the device without running /etc/init.d/network start :P
