Thread: Execute prog as other user

Hello All,

I'm writing a program that will execute external programs under a linux machine. This program will run as root and each external program must be run by the user that is calling it...

for example:

in the exec.conf file I have:
#user|binary
apache|/bin/apache_clean

The prog will read the file and should execute the binary as the user, in this case /bin/apache_clean by the user apache.

I'm using execv to execute the external program but I didnt find out how to execute it as another user. I've tryed execve with no sucess.

Any ideias ?

Thanks,

Salem, Thank you one more time for your help ! Its very simple:

Code:

setuid(userid);

Thanks,
