The routing table on a host holds a list of destination network and the routes to those networks. This recipe describes adding entries to this routing table that will not persist following a reboot. These temporary routes [...]

Domain name Servers (DNS) are an important but invisible part of the internet, and form one of the largest databases on it. Each machine on an internet is assigned a unique address, called an IP address, which is 32 bit number and is expressed as 4 octets. The method user to represent these IP addresses [...]

By default any modern Linux distributions will have IP Forwarding disabled. This is normally a good idea, as most peoples will not need IP Forwarding, but if we are setting up a Linux router/gateway or maybe a VPN server (pptp or ipsec) or just a plain dial-in server then we will need to enable forwarding.

Normally when you add a new IP to a network interface in a RedHat based system you create a file ifcfg-eth0:x in /etc/sysconfig/network-scripts/. For example: /etc/sysconfig/network-scripts/ifcfg-eth0:0 DEVICE=eth0:0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.0.100 NETMASK=255.255.255.0 NETWORK=192.168.0.0 BROADCAST=192.168.0.255 TYPE=Ethernet Similar to the above example you can create several aliases. But what if you have to add a lot of IPs [...]
