Hello,
I do setgid the way I'm aware of. But user is still in 0 group after that:
uid=20020(fcgi) gid=20020(fcgi) groups=20020(fcgi),0(wheel)
of course it is not included in 0 group in /etc/groups
use POSIX;
my( $uid, $gid ) = qw/20020 20020/;
setgid( $gid ); $) = $gid; $( = $gid; die "Set group ($gid): $!"
if ( $( != $gid ) or ( $) != $gid );
setuid( $uid ); $> = $uid; $< = $uid; die "Set user ($uid): $!"
if ( $< != $uid ) or ( $> != $uid );
print `id`;
There are definitely things I'm missing here. Is it possible to avoid any other group from to appear on getgroups() ?
Thank you.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
