Have you actually tried this? >The shell would get invoked with '-' as the first character of argv[1] >not argv[0]. No, he's perfectly correct. When you invoke a shell script, the shell gets invoked with name of the shell script in argv[0]. So if the name of the shell script is '-', then that's what the shell will see. Most Bourne shells will interpret the '-' as meaning "I'm an interactive login shell". So it doesn't matter at all what's in the setuid shell script; if you symlink it to the name '-', when you execute it, you will get a setuid shell. This is not a kernel programming issue --- even if you have a kernel which support setuid shell scripts by handing the shell interpreter the script in a file descriptor (which is the only way to avoid the race condition security hole) --- if you have a shell which automatically becomes an interactive shell when argv[0] contains a leading '-', all is lost. The bottom line is that setuid shell scripts are tricky. Even if you have a "secure system that supports setuid scripts", if the system administrator then installed the Bourne shell, and writes setuid scripts referencing it, you will still lose. True, writing any type of setuid program is tricky; but adding in an additional level of interpretation on top of things compounds the possibilities for security holes. - Ted {/tmp}, Level 2 9# cat > foo #!/bin/sh echo foo {/tmp}, Level 2 10# chmod 4755 foo {/tmp}, Level 2 11# , Stopped {/tmp} 207% ln -s foo - -: File exists {/tmp} 208% - $ cat >bar #!/bin/sh echo "do nasty things" $ chmod 4755 bar $ ls -l bar -rwsr-xr-x 1 root 33 Oct 4 23:29 bar Need I say more? ------------------------------ From: ghhwang@pllab1 (Gwan-Hwan Hwang) Subject: help! dvips failed Date: 5 Oct 1993 07:15:23 GMT Reply-To: ghhwang@cs.nthu.edu.tw Dear friends, I installed SLS1.03 including latex of it.

I think the next big upgrade (probably when XFree86 2.0 comes out) will move the symbolic links out of the packages themselves and into the installation scripts that are included with each package. That's if I can toss together something that does this automatically - I sure ain't gonna do it by hand. :^) It should then be possible to upgrade evry part of an existing system, including the whole base system, libraries, kernel, etc. 1.0.4 is not a real massive overhaul. The biggest improvements come in the X series. You might want to remove just your X stuff, and then use the new bootdisk to add the X windows series to your system. -- Patrick Volkerding volkerdi@mhd1.moorhead.msus.edu bf703@cleveland.freenet.edu ------------------------------ From: bf703@cleveland.Freenet.Edu (Patrick J.

Anyone know what I don't have configured correctly? If you included a clock -s or clock -s -u (if your hardware clock is set in GMT - recommended, as this manages daylight saving time automatically) in your /etc/rc and made a proper link from your local timezone to localtime in /usr/lib/zoneinfo, you should be well set. See /usr/lib/zoneinfo/time.doc for further details. Another place to look into is /etc/defaults/login. Maybe there is a TZ variable defined.
