ssh root@localhost suid bit is considered harmful

• pxeger1 3y ago
  Why considered harmful? Connecting to a daemon running as root still relies on the security of the daemon.

    Because it's security escape hatch. It's not needed. Suid programs caused many vulnerabilities. There must not be a way to get more privileges, only less.

  You can do that if you had the forethought to edit your /etc/securetty file before nuking su, to allow root logins on the ptys used by sshd. If not, logging in on a physical console would work or rebooting to single either mode or whatever.
