Weird! Not setuid on my ubuntu machine.

• jandrese 6y ago
  It is on my Ubuntu 18.04.5 LTS machine: -rwsr-xr-x 1 root root 64424 Jun 28 2019 /bin/ping

    No longer on 20.10. Curious why it's different: -rwxr-xr-x 1 root root 76744 Aug 23 15:08 /bin/ping

      Checked an Ubuntu 20 machine and you're right. Instead ping has an extended attribute: % getcap /bin/ping /bin/ping = cap_net_raw+ep

  It's because of linux capabilities specificly CAP_NET_RAW How to check: $ getcap $(which ping) /usr/bin/ping = cap_net_raw+ep More about it on [1] https://blog.container-solutions.com/linux-capabilities-in-practice https://blog.container-solutions.com/linux-capabilities-in-p...
