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 (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

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 to /etc/network/interfaces and overwrite one of the init scripts to disable network configuration in /etc/elphel393/init_elphel393.py on startup.
