I have a user username who is member of group dip. I'm trying to run /usr/sbin/pppd, which is mode -rwsr-xr--, owner root, group dip, as user username. However, I get the error message: /usr/sbin/pppd: using the noauth option requires root privilege

Is there some way to go around that, please?

According to the man page for pppd:

Do not require the peer to authenticate itself. This option is privileged.

So it appears that you have to have root privilege to use that option. Just because your user is allowed to run pppd, does not mean that the user is privileged to do everything that pppd can use.

Why can't you run it with root privileges?

  • Well, I can. I just did not want to in my specific case. Jun 16, 2016 at 9:18
  • Right, right. Well, if you can find a way to use it sans the privileged options, you can get away with it. I'm not sure what your use case is, exactly.
