Problem description:
Whenever attempting to run the ping command on any target within a Nix-based repl, a permission denied exception will occur.
Expected behavior:
The ping command will go through and test the availability of the target machine.
Actual behavior:
I’ve tested this with any of the available Nix packages that implement ping:
toybox
unixtools.ping
iputils
telnet
busybox
In every case, a permission denied exception will occur. Below are some sample outputs:
- Toybox
ping: socket SOCK_DGRAM 1: Permission denied
Kernel bug workaround:
echo 0 99999999 | sudo tee /proc/sys/net/ipv4/ping_group_range
- IPUtils
ping: socket: Operation not permitted
- Busybox
PING 1.1.1.1 (1.1.1.1): 56 data bytes
ping: permission denied (are you root?)
Steps to reproduce:
Create a new Nix-based repl, install one of the packages that implement ping, and execute ping on any target within the shell.
