Hello monks,

I'm trying to write a suid script.

perldoc perlsec, and Erik Hensema in this node, both say that perl will automatically call suidperl if it detects that the script it's starting is setuid.

In my case, that doesn't seem to be happening. I've written a little test script (see my scratchpad). If I change its ownership to root and make it setuid, it should print: 
UID:  <my uid>
EUID: 0

[download]

Right? But it doesn't. I get: 
UID:  <my uid>
EUID: <my uid>

[download]

If I substitute /usr/bin/suidperl for /usr/bin/perl in the #! line, it does the right thing. But Erik Hensema (same node as above) says I shouldn't do that.

If I shouldn't do that, how do I get my script to do the right thing?

Thanking you.
