"ignore subnet discovery" on Linux

Hi everyone,

just a quick hint about GEV cameras and “ignoring subnets” on Linux.
Windows allows this by default (which is technically not ok :sob:).

  1. CVB has a feature to disregard subnet mask for discovery.
  2. The Linux Kernel does not permit this by default.

In order to for all network interface to permit disregarding the subnet mask create and execute a .sh file with the following content:

for filter in /proc/sys/net/ipv4/conf/*/rp_filter; do echo 0 > $filter; done

This stops the kernel from “filtering” these boardcasts. This script will allow subnet discover until the next reboot of the system, i.e. enough time to configure your camera.
