Some coding critique (not knowing anything about Tk):

$hlist->header('create', 0, -text => 'user');
$hlist->header('create', 1, -text => 'gid');
$hlist->header('create', 2, -text => 'pid');
$hlist->header('create', 3, -text => 'machine');
$hlist->header('create', 4, -text => 'service');
$hlist->header('create', 5, -text => 'ip-adres');
$hlist->header('create', 6, -text => 'logon time');
[download]

I would code this as:

my $option = 0;
foreach (qw(user gid pid machine service ip-adres logon)) {
    $hlist->header('create', $option++, -text => $_);
}
[download]

because I hate to repeat things myself that can be repeated by the computer. And I would try to do something similar for the rest of the snippet. And yes, I cheated a little by changing "logon time" to "logon" to make it work with qw(). ;-)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
