RHEL Network Configuration

RedHat Network configuration

Run nmtui

Then maybe;

service network restart

If we wish to change from DHCP to a static IP, edit the following file;

Replacing the if cfg-eth0 to suit the network interface.

Change BOOTPROTO from dhcp to static and add IPADDR=xxx.xxx.xxx.xxx

Might be worth changing ONBOOT to yes, however if you run nmtui and check Automatically Connect, this should do this for us.

RHEL Network configuration

The primary network configuration files are as follows:

/etc/hosts

Resolve host names that cannot be resolved any other way, by DNA for example. 

/etc/resolv.conf

This file specifies the IP addresses of DNS servers and the search domain.

/etc/sysconfig/network

This file specifies routing and host information for all network interfaces.

/etc/sysconfig/network-scripts/ifcfg-interface-name

For each network interface, there is a corresponding interface configuration script. Each of these files provide information specific to a particular network interface.

See also nmtui (similar to netconfig on Slackware)

If not installed;

yum install NetworkManager-tui

To change the IP address on RedHat:

ifconfig eth0 192.168.254.199 netmask 255.255.255.0 up (temp, will change on next boot)

vi /etc/sysconfig/network-scripts/ifcfg-eth0

Restart network with:

service network restart

With Slackware we of course use netconfig 
Or
edit /etc/rc.d/rc.inet1.conf

and restart with /etc/rc.d/rc.inet1 restart
