Why is the ping failing on Debian 12?

[precisionpete]

The following code works fine on Windows, Ubuntu 22.04, MacOS, and some others. But it fails on Debian 12.

I've tried running it as root vs a user with the same result.

I've also tried SetPrivileges and the same result.

How to resolve this?

Thanks

try about this, sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"

try about this, sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"

Fixed it for me too. Thanks @unmurphy. Would you mind explaining why it happens and how it solves the problem?
