From: "Vladimir Lettiev" <thecrux@gmail.com> To: "ALT Linux Team development discussions" <devel@lists.altlinux.org> Subject: [devel] Q: sgid Date: Mon, 22 Sep 2008 16:32:42 +0400 Message-ID: <3b8491740809220532u115d53faw994dad42938c704@mail.gmail.com> (raw) Добрый день. Вот такой код: #include <stdio.h> #include <stdlib.h> #include <grp.h> int main(int argc, char *argv[]) { gid_t egid; struct group *group; egid = getegid (); group = getgrgid (egid); fprintf (stderr, "egid: %d, egroup: %s\n", egid, group->gr_name); } скомпилировал, поменял группу владельца на root, установил sgid флаг $ gcc -o program program.c $ sudo chgrp root program $ sudo chmod 2755 program $ ./program egid:500, egroup:crux ? Это всё происходит на системе с ALT Sisyphus. Таже самая программа собранная в ubuntu, как и ожидалось, выдаёт: egid:0, egroup: root Почему так? -- Vladimir Lettiev aka crux <theCrux@gmail.com>
