KB1456 - How to change SmartServer IP address using SFTP or console

The SmartServer IP address is typically changed using the SmartServer Configuration Web page. This article shows how to change the IP address from the using the SmartServer console/ssh or using SFTP

Instructions

You can change the SmartServer LAN and WAN port assignments by modifying the following file and rebooting the SmartServer.

/etc/network/interfaces

Make a backup of the file before changing it. You only need to modify the ports you are using :LAN port (eth0) and/or WAN port (eth1)

Example 1 using static IP address with only LAN port. WAN port not used

$ cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

source-directory /etc/network/interfaces.d

auto lo

iface lo inet loopback

iface eth0 inet static

address 10.0.0.228

netmask 255.255.255.0

gateway 10.0.0.1

        pre-up /root/.setup/ethernet/eth_mac eth0

iface eth1 inet dhcp

        pre-up /root/.setup/ethernet/eth_mac eth1

hotplug ip70

iface ip70 inet static

        pre-up ip link set name ip70 dev dummy0

        pre-up ifconfig ip70 multicast

        address 172.24.25.128

        netmask 255.255.255.0

Example 2 file for BACnet with using dhcp for the LAN port (eth0) and static IP address for the WAN port (eth1)

cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

# Include files from /etc/network/interfaces.d:

source-directory /etc/network/interfaces.d

auto lo

iface lo inet loopback

iface eth0 inet static

address 192.168.92.3

netmask 255.255.255.0

        pre-up /root/.setup/ethernet/eth_mac eth0

iface eth1 inet dhcp

        pre-up /root/.setup/ethernet/eth_mac eth1

hotplug ip70

iface ip70 inet static

        pre-up ip link set name ip70 dev dummy0

        pre-up ifconfig ip70 multicast

        address 172.24.25.128

        netmask 255.255.255.0

apollo@smartserver-17qam88:~$

WinSCP

You will need to log in as root to change this file.

SSH

You can log in using apollo login but will need to edit will need to "sudo". The following instructions use nano to edit the interfaces file.

Copy the following console commands to a text only editor (like notepad) and then copy them one by one to the SmartServer console:

sudo cp /etc/network/interfaces /etc/network/interfaces_old

ls -l /etc/network

sudo nano /etc/network/interfaces

cat /etc/network/interfaces

sudo reboot
