Montgomery) Newsgroups: net.unix-wizards Subject: Query about setuid() Message-ID: <131@nvuxd.UUCP> Date: Wed, 6-Feb-85 20:21:41 EST Article-I.D.: nvuxd.131 Posted: Wed Feb 6 20:21:41 1985 Date-Received: Fri, 8-Feb-85 02:10:59 EST Organization: Bell Communications Research Lines: 47I have run the following program on a System V VAX and on a newly aquired Pyramid 90x (I ran it setuid to uucp): #include main() { int Uid, Euid; Uid = getuid(); Euid = geteuid(); printf("uid = %d euid = %d\n", Uid, Euid); printf("setuid(%d) returns %d\n", Uid, setuid(Uid)); printf("uid = %d euid = %d\n", getuid(), geteuid()); printf("setuid(%d) returns %d\n", Euid, setuid(Euid)); printf("uid = %d euid = %d\n", getuid(), geteuid()); } on the VAX (USG 5.0.5) it gives uid = 882 euid = 5 setuid(882) returns 0 uid = 882 euid = 882 setuid(5) returns 0 uid = 882 euid = 5 on the Pyramid it gives uid = 100 euid = 5 setuid(100) returns -1 uid = 100 euid = 100 setuid(5) returns -1 uid = 100 euid = 100 I'm wondering which is correct. The behavior of the Pyramid will break some things I have on the VAX (including, I believe, the honey danber uucp). I'm assuming that (at least in the att universe) the Pyramid is broken. What should 4.2 do? Please reply by mail, I'll forward or post replies if there is interest. -- John Montgomery Bell Communications Research ...{allegra,ihnp4}!nvuxd!johnm
