Post subject: | SUID |
Am I correct in guessing that Linux does not support SUID? For example, if I write a script as root like : #!/bin/sh /etc/init.d/xinetd restart and then give it permissions chmod 4755. Doesn't that mean that any user can then start xinetd? Can anybody clarify this for me. Thanks. |

SUID is supported, but not for shell scripts. This is for security reasons (too easy to exploit to give root access, apparently). I don't know if this can be changed - probably, knowing linux - but the point is that you shouldn't be doing such a thing anyway. If you really need a normal user to run such a command, investigate sudo, or change the permissions on "service". bukharin |
