Description

In the firmware 20180511 (and older) the ip address and network mask of the camera are set by /etc/elphel393/init_elphel393.py script overriding /etc/network/interfaces, which appeared to have incorrect configuration.

In the newer firmware releases this functionality will be disabled to bring the network setup to a more traditional way, i.e. by modifying /etc/network/interfaces.

Follow the instructions below to fix this for the older firmware.

How to update network setup for 20180511 (or older firmware)

Quick instructions

  • Camera is online. The IP address can be any, e.g., 192.168.0.9
  • PC: in a terminal window (GNU/Linux OS) type the following commands:
wget https://community.elphel.com/files/393/fix_network_config/fix_net_config.tar.gz
tar -xzpf fix_net_config.tar.gz
cd fix_net_config
./host_script.sh 192.168.0.9
  • If the boot device is internal NAND flash, run shutdown -hP now to commit changes before power-cycling the camera. Not required if booted from uSD card.

Next, any extra changes related to setting ip address, netmask or gateway made to /etc/elphel393/init_elphel393.py can be commented out or the original file can be used.

Description

From a Linux PC, download fix_net_config.tar.gz. The archive contains 2 scripts - one (shell) is run from the host PC, another (python) will be copied and automatically run on the camera. The python script will write the current configuration (IP, mask, default gateway for eth0) to /etc/network/interfaces and overwrite one of the init scripts to disable network configuration in /etc/elphel393/init_elphel393.py on startup.
