"su -" in CGI script ?

[Robert Nilsson]

Hello

I'm trying to execute a specific command from a CGI script written in PERL.
I have to be a special user so I've tried to use "su -" but it doesn't work.
The CGI script is running as the user apache on the server, right? Is that
the problem? Is there any other way to execute something with "system" as
someone else within perl?

for example:

system "su - surf -c /home/surf/bin/vnc start SV_STALOVN";

We dont know, you're telling the story.

Try a setuid wrapper, to run as the user you want.

This is an OS question (UNIX) not a perl one. "su" requires a password. If
you're running a CGI script there's no terminal from which it can get
the password. Read "man su" for details.

I don't understand what you mean by << executing something with "system" >>,
though.

Doh; I was still thinking in UNIX terms. Glad to see you've got a solution
from another poster, though
