ping do not work in lxc containers

[Apollon77]

• see subject ... all IPS are returned as offline and so only localhost is checked
• docker has other issues too

Found out that this seems to be a bug in proxmox for long time now. -> https://forum.proxmox.com/threads/ping-with-unprivileged-user-in-lxc-container-linux-capabilities.42308/
The problem is that the rights are not correct set for ping.

I have written a simple script to check if the rights are correct and if not they will be set. I am not sure where is the best place to add this function, while the same bug possible effect other adapter when they want to use ping.
We should also remember that a system update can change the rights again, as someone has written on the forum thread.

`const os = require('os');
const { exec } = require('child_process');

if (os.type() === 'Linux') {
exec('setcap -v cap_net_raw+p /bin/ping', (error, stdout, stderr) => {

if (stdout) {
  if (stdout.includes('differs in [p]')) {
    exec('sudo setcap cap_net_raw+p /bin/ping', (error, stdout, stderr) => {
      if (stderr) {
        console.error(`Error setting permissions: ${error}`);
      } else {
        console.log('Permission set for pinging.');
      }
    });
  }
}

});
}`
