IIRC, having the stick bit set on a binary only allows the setuid() call to succeed, it does not automatically force the elevated permissions on the binary. So, it's likely that utmsmom doesn't have support for getting elevated permissions. > > Excuse me, what about sudo? > > Two things: First, I do not want to use sudo (this is Ubuntu-style, and I > hate Ubuntu!) sudo predates Ubuntu by some years, if not decades. sudo is meant to be a more flexible su, which seems to be exactly what you need. > and sudo is not the way I want it to do for some reasons. Could you please elaborate? If you have specific, technical doubts about using sudo as a solution, I'd be willing to investigate other avenues. Failing that, adding something like: %dialout = NOPASSWD: NOSETENV: /usr/bin/umtsmom to your /etc/sudoers should be fine. Depending on how umtsmom works, it might be possible and valuable to add "NOEXEC:" as an additional Tag_Spec. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
