Useful Networking commands in Linux
To get a list/modify the network interfaces on the host run the command:
ip link
To see the IP addresses assigned to the interfaces:
ip addr
Set ip addresses on the interfaces, these will only be valid until the next restart.
ip addr add 192.168.1.10/24 dev eth0
To persist the changes run set them in the /etc/network_interfaces file
Get the ip table route configuration:
ip route
Add to the ip table routing:
ip route add 192.168.1.0/24 via 192.168.2.1
Check if IP forwarding is available on the host:
cat /proc/sys/net/ipv4/ip_forward
