isAlive false, no error in electron, but isAlive true (same IP) under node?

isAlive false, no error in electron, but isAlive true (same IP) under node?

To narrow this down, I use the source code of node-ping to write code that does the same thing, in a very minimal version inside the electron app. "out" is just console log, but it goes to a special text box which is easy to see while the program is running.

var cp = require('child_process');
ping = cp.spawn("ping", ["192.168.0.142"]);
ping.stdout.on('data', (data) => {
  out(`stdout: ${data}`);
});

ping.stderr.on('data', (data) => {
  out(`stderr: ${data}`);
});

ping.on('close', (code) => {
  out(`child process exited with code ${code}`);
});

the stderr message comes back as stderr: ping: icmp open socket: Operation not permitted
and the child process existed with code 2.

Why doesn't node-ping report an error? Maybe I wrote the minimal code incorrectly? But the same code runs just fine under node, so electron is failing to run it with the same permissions...

Wonder if it's related to this:
electron/electron#18521

Submitted a bug report to Electron.
electron/electron#27168

Try 0.4.1, and see whether the error stderr: ping: icmp open socket: Operation not permitted can be reported now

Sorry, it's been 4 months so we moved on and are no longer using this library at all. Rather than pretend that I could find time to revert, update the library and try it, I will just let you know that testing won't happen. Close this issue if you feel you've corrected the problem.

oops. Anyway, thanks for the report.
