Quite old thread, but what worked for me is compile "socat" it from sources in an Ubuntu Desktop 20.04 LTS x64 VM and copy it over to /storage/.kodi/addons/virtual.network-tools/bin
On the Ubuntu 20.04 LTS x64 VM run (works also booting live CD without install):
sudo apt update
sudo apt install make binutils gcc-arm-linux-gnueabihf
wget http://www.dest-unreach.org/socat/download…-1.8.0.0.tar.gz
tar -xvf socat-1.8.0.0.tar.gz
cd socat-1.8.0.0
./configure --host=arm-linux-gnueabihf
make
Then copy "socat" binary over and you're ready to go.
Hope it helps.
