1. First stop and disable the gnome network manager from running on boot.

#systemctl stop NetworkManager.service
#systemctl disable NetworkManager.service

2. Now start and enable the network service to run on boot.

#systemctl restart network.service
#systemctl enable network.service

Set the Static Address
1. Check which interface(s) you want to set as static.

# ifconfig
em1: flags=4163 mtu 1500
inet 192.168.1.148 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::dad3:85ff:feae:dd4c prefixlen 64 scopeid 0×20 ether d8:d3:85:ae:dd:4c txqueuelen 1000 (Ethernet)
RX packets 929 bytes 90374 (88.2 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1010 bytes 130252 (127.1 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 19

lo: flags=73mtu 16436
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0×10
loop txqueuelen 0 (Local Loopback)
RX packets 32 bytes 3210 (3.1 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 32 bytes 3210 (3.1 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

2. Next edit the config file for the required interface.

vim /etc/sysconfig/network-scripts/ifcfg-em1

3. Edit the config file to look similar to the following.

Change the BOOTPROTO from “dhcp” to “static”. Also adding IPADDR, NETMASK, BROADCAST and NETWORK variables and make sure ONBOOT is set to yes.

UUID=”e88f1292-1f87-4576-97aa-bb8b2be34bd3″
NM_CONTROLLED=”yes”
HWADDR=”D8:D3:85:AE:DD:4C”
BOOTPROTO=”static”
DEVICE=”em1″
ONBOOT=”yes”
IPADDR=192.168.1.2
NETMASK=255.255.255.0
BROADCAST=192.168.1.255
NETWORK=192.168.1.0
GATEWAY=192.168.1.1

Exit the editor by pressing ‘:wq’ and enter.

4. Restart the network service to apply the settings.

systemctl restart network.service

router based connection.
peer to peer connection.

Router Based Connection

In this type of connection it is assumed that your laptop is already in the network, lets say your ip to be 192.168.1.3 and you machine has ssh support.Now in Raspberry it is important that it has ssh support as well. Connect your raspberry pi into the router using a network cable, your raspberry will now have an ip address that was provided by the dhcp server. our next step is to find out the ip address of raspberry pi. In order to get the ip address of raspberry pi we could type ifconfig and look for “inet addr: x.x.x.x” if your raspberry is connected to a monitor. else if it is headless ( without a monitor) then we could look at the ip table of your router by seeing who is connected to the network. now that we know the ip address we could do the following from host machine

$ ssh pi@192.168.1.3

where 192.168.1.3 is the ip address of Raspberry provided by dhcp server.

Peer To Peer Connection

In a peer to peer based connection the Raspberry and host machine is directly connected to each other using a network cable. In order to do this we need static ip’s at both the ends. so we need to make the following change in /etc/network/interfaces file host machine, (note: dont forget to take a backup of /etc/network/interfaces file)

$sudo vim /etc/network/interfaces

auto eth0
iface eth0 inet static
address 192.168.10.2
netmask 255.255.255.0

add the above shown line to the file.

do the same in Raspberry pi as well but the only difference is that the ip address should be 192.168.10.3, note that the network id 192.168.10 should remain same.

after doing this restart the network service by typing the command or by restarting the machine.

$sudo /etc/init.d/networking restart.

then do a

$ssh pi@192.168.10.3

and now it will ask for password, provide the password. So you are now logged it to raspberry pi via ssh.
