--qMm9M+Fa2AknHoGS Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, I'm trying to let a program get super-user rights by calling su in a pseudo-terminal (the attached program demonstrates this). This however does not work, because su gets stuck in ttywait. Can anyone tell me what I'm doing wrong, or at least provide me with a program that does do the trick? Thanks in advance, Theo P.S. Please reply to me directly.
