| 16 | * Open up the Terminal application |
| 17 | * Backup the default DHCP based network configuration: |
| 18 | |
| 19 | {{{ |
| 20 | sudo cp /etc/network/interfaces /etc/netwrok/interfaces.default |
| 21 | }}} |
| 22 | |
| 23 | * Next we will open the network interfaces file for editing |
| 24 | |
| 25 | {{{ |
| 26 | sudo nano /etc/network/interfaces |
| 27 | }}} |
| 28 | |
| 29 | * Now we will edit the interfaces file. factory default is: |
| 30 | |
| 31 | {{{ |
| 32 | # interfaces(5) file used by ifup(8) and ifdown(8) |
| 33 | auto lo |
| 34 | iface lo inet loopback |
| 35 | |
| 36 | auto eno1 |
| 37 | iface eno1 inet static |
| 38 | address 192.168.100.100/24 |
| 39 | |
| 40 | auto enp5s0 |
| 41 | # Comment out the following lines to disable enp5s0 |
| 42 | iface enp5s0 inet dhcp |
| 43 | # and then uncomment the following lines to disable enp5s0 |
| 44 | #iface enp5s0 inet static |
| 45 | # address 0.0.0.0 |
| 46 | # netmask 255.255.255.255 |
| 47 | |
| 48 | auto can0 |
| 49 | iface can0 inet manual |
| 50 | # bitrate 1MBps |
| 51 | # increase TX queue length because of the pulsed nature of |
| 52 | # the traffic we generate |
| 53 | pre-up /sbin/ip link set can0 type can bitrate 1000000 |
| 54 | up /sbin/ip link set can0 up |
| 55 | down /sbin/ip link set can0 down |
| 56 | }}} |
| 57 | |
| 58 | |
| 59 | * We will change it to: |
| 60 | |
| 61 | {{{ |
| 62 | # interfaces(5) file used by ifup(8) and ifdown(8) |
| 63 | auto lo |
| 64 | iface lo inet loopback |
| 65 | |
| 66 | auto eno1 |
| 67 | iface eno1 inet static |
| 68 | address 192.168.100.100/24 |
| 69 | |
| 70 | auto enp5s0 |
| 71 | iface enp5s0 inet static |
| 72 | address 192.168.200.123/24 |
| 73 | |
| 74 | auto can0 |
| 75 | iface can0 inet manual |
| 76 | # bitrate 1MBps |
| 77 | # increase TX queue length because of the pulsed nature of |
| 78 | # the traffic we generate |
| 79 | pre-up /sbin/ip link set can0 type can bitrate 1000000 |
| 80 | up /sbin/ip link set can0 up |
| 81 | }}} |
