Howto make license request for Neuromag Software on ubuntu 20

1. Switch link /bin/sh to bash, becouse by default it point to dash

ln -sf /bin/bash /bin/sh

2. Necessary rename active network device to old naming scheme eth*

In modern linux simple way is using netplan manifest.

There is need add option for rename device which matched by it macaddr. E.g. as described below

cat /etc/netplan/99-network.yaml
network:
  version: 2
  ethernets:
    eth0:
      addresses:
        - 192.168.1.15/24
      gateway4: 192.168.1.1
      nameservers:
        addresses:
          - 192.168.1.1
        search:
          - host.localnet
      match:
        macaddress: 00:25:90:c9:37:34
      set-name: eth0

For apply it need reboot host.

3. License probe utility use 32-bit code.

It need system wide fixing

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 -y

4. The usual way of placing neuromag software is /opt/neuromag

So it should be done

5. Generation script is very ancient

At first need to install depricated utility

sudo apt-get install net-utils -y

Patch file need for fixes old and incorrect statements.

     else
 	printf "macaddr[$lanno]="
 	echo `/usr/sbin/lanscan | grep $interface | awk '{ print $2 }'`

Then need apply patch to probe script like follow

patch license_info patch.txt

6. Finally, we can make a license request
