To understand what I'm asking, it's important to distinguish from among the several uses of SUID in Unix. I have a project that uses an executable in the user's PATH which is owned by the project and which has the SUID bit set. In this way, when it runs, it runs in the context of the file's owner, not the calling user. This way, it has ...

Since you can't suid a script and can only suid an executable I wanted to use the generic script compiler "shc" to create an executable and then set that executable's suid bit. Only problem is that on ubuntu jaunty I can't find shc or when I do apt-get i...
Hi, I'm interested in writing a PAM module that would make use of a popular authentication mechanism for Unix logins.

I googled around and found pam_python, which allows PAM modules to invoke the python intrepreter, t...

I realize this might seem redunant with the ability to restart the computer in other ways, but the choice needs to stay there. I've tried using system() to call the following: a suid-root shell script a non-suid s...
I'm trying to add a feature to a legacy script. The script is suid, and uses perl -T (taint mode: man perlsec), for extra security. The feature I need to add is implemented in Python. My problem is that I can't convince perlsec to preserve the suid permissions, no matter how much I launder the environment and my command lines. This is...
I need to debug a program on Linux with Eclipse (gdb). The program run as root and is quite large. The binary with debug symbols is about 250MB large and has more than 60 running threads after startup. I'm thinking about the best solution: Use gdbserver Run Eclipse as root Set gdb suid I think number 1 (gdbserver) would be the bes...
