NMS help!
« on: August 20, 2004, 01:25:49 AM »
After wrestling with TFmail for a day and a night, I discoverd the "easier" NMS mail recommended in the forum (http://www.lunarforums.com/forum/viewtopic.php?t=18221).  

I believe I've followed all of the instructions, made the changes in the .pl file and uploaded it and changed the permission, then set the action in the form to the .pl file in the cgi folder... but the script is still not working.

Since I'm not an HTML programmer, it's pretty likely I've missed something, but I can't for the life of me figure out what.  The only things I can think of, after going through it over and over again:

I've built the form in Dreamweaver, so some of the HTML code is slightly different - for instance, instead of

<input type="textbox" name="email">

it says

<input name="email" type="text" id="email" size="50">

But would that make any difference in the functioning of the cgi script?

Also, where it says "localhost" in the script, I've left it just like that.  Is that correct, or am I supposed to replace this with the name of the local host?

Has anyone else followed these instructions and discovered things that experience progammers might take for granted but that a clever novice might overlook?

Post a link to your html form and post your script please.

Also what was the error you received?

This is a base class for classes implementing low-level email
sending objects for use within CGI scripts.

=head1 METHODS

=over

=item output_trace_headers ( TRACEINFO )

Uses the print() virtual method to output email abuse tracing headers
including whatever useful information can be gleaned from the CGI
environment variables.

The TRACEINFO parameter should be a short string giving the name and
version of the CGI script.

=head1 VIRTUAL METHODS

Subclasses must implement the following methods:

=over

=item newmail ( TRACEINFO, SENDER, @RECIPIENTS )

Starts a new email.  TRACEINFO is the script name and version, SENDER is
the email address to use as the envelope sender and @RECIPIENTS is a list
of recipients.  Dies on error.

=item print ( @ARGS )

Concatenates the arguments and appends them to the email.  Both the
header and the body should be sent in this way, separated by a single
blank line.  Dies on error.

=item endmail ()

Finishes the email, flushing buffers and sending it.  Dies on error.

CGI::NMS::Script - base class for NMS script modules

=head1 SYNOPSYS

  use base qw(CGI::NMS::Script);

  ...
 
=head1 DESCRIPTION

This module is a base class for the C<CGI::NMS::Script::*> modules,
which implement plugin replacements for Matt Wright's Perl CGI
scripts.

=head1 CONSTRUCTORS

=over

=item new ( CONFIG )

Creates a new C<CGI::NMS::Script> object and performs compile time
initialisation.

CONFIG is a key,value,key,value list, which will be stored as a hash
within the object, under the name C<CFG>.

=cut

sub new {
  my ($pkg, @cfg) = @_;

  my $self = bless {}, $pkg;

  $self->{CFG} = {
    DEBUGGING           => 0,
    emulate_matts_code  => 0,
    secure              => 1,
    locale              => '',
    charset             => 'iso-8859-1',
    style               => '',
    cgi_post_max        => 1000000,
    cgi_disable_uploads => 1,

    $self->default_configuration,

    @cfg
  };

  $self->{Charset} = CGI::NMS::Charset->new( $self->{CFG}{charset} );

  $self->init;

  return $self;
}

=back

=item CONFIGURATION SETTINGS

Values for the following configuration settings can be passed to new().

Subclasses for different NMS scripts will define their own set of
configuration settings, but they all inherit these as well.

=over

=item C<DEBUGGING>

If this is set to a true value, then the error message will be displayed
in the browser if the script suffers a fatal error.  This should be set
to 0 once the script is in service, since error messages may contain
sensitive information such as file paths which could be useful to
attackers.

Default: 0

=item C<name_and_version>

The name and version of the NMS script, as a single string.

=item C<emulate_matts_code>

When this variable is set to a true value (e.g. 1) the script will work
in exactly the same way as its counterpart at Matt's Script Archive. If
it is set to a false value (e.g. 0) then more advanced features and
security checks are switched on. We do not recommend changing this
variable to 1, as the resulting drop in security may leave your script
open to abuse.

Default: 0

=item C<secure>

When this variable is set to a true value (e.g. 1) many additional
security features are turned on.  We do not recommend changing this
variable to 0, as the resulting drop in security may leave your script
open to abuse.

Default: 1

=item C<locale>

This determines the language that is used in the format_date() method -
by default this is blank and the language will probably be English.

Default: ''

=item C<charset>

The character set to use for output documents.

Default: 'iso-8859-1'

=item C<style>

This is the URL of a CSS stylesheet which will be used for script
generated messages.  This should probably be the same as the one that
you use for all the other pages.  This should be a local absolute URI
fragment.  Set C<style> to 0 or the empty string if you don't want to
use style sheets.

Default: '';

=item C<cgi_post_max>

The variable C<$CGI::POST_MAX> is gets set to this value before the
request is handled.

Default: 1000000

=item C<cgi_disable_uploads>

The variable C<CGI::DISABLE_UPLOADS> gets set to this value before
the request is handled.

Default: 1

=item C<no_xml_doc_header>

If this is set to a true value then the output_cgi_html_header() method
will omit the XML document header that it would normally output.  This
means that the output document will not be strictly valid XHTML, but it
may work better in some older browsers.

Default: not set

=item C<no_doctype_doc_header>

If this is set to a true value then the output_cgi_html_header() method
will omit the DOCTYPE document header that it would normally output.
This means that the output document will not be strictly valid XHTML, but
it may work better in some older browsers.

Default: not set

=item C<no_xmlns_doc_header>

If this is set to a true value then the output_cgi_html_header() method
will omit the C<xmlns> attribute from the opening C<html> tag that it
outputs.

=back

=head1 METHODS

=over

=item request ()

This is the method that the CGI script invokes once for each run of the
CGI.  This implementation sets up some things that are common to all NMS
scripts and then invokes the virtual method handle_request() to do the
script specific processing.

=cut

sub request {
  my ($self) = @_;

  local ($CGI::POST_MAX, $CGI::DISABLE_UPLOADS);
  $CGI::POST_MAX        = $self->{CFG}{cgi_post_max};

  eval { local $SIG{__DIE__} ; $self->handle_request };
  my $err = $@;

  if ($self->{CFG}{locale}) {
    POSIX::setlocale( LC_TIME, $old_locale );
  }

    my $message;
    if ($self->{CFG}{DEBUGGING}) {
      $message = $self->escape_html($err);
    }
    else {
      $message = "See the web server's error log for details";
    }

    $self->output_cgi_html_header;
    print <<END;
 <head>

  <h1>Application Error</h1>
  <p>
   An error has occurred in the program
  </p>
  <p>
   $message
  </p>
 </body>
</html>
END

    $self->warn($err);
  }
}

=item output_cgi_html_header ()

Prints the CGI content-type header and the standard header lines for
an XHTML document, unless the header has already been output.

=cut

sub output_cgi_html_header {
  my ($self) = @_;

  return if $self->{Done_Header};

  }
  else {
    print qq|<html xmlns="http://www.w3.org/1999/xhtml">\n|;
  }

  $self->{Done_Header} = 1;
}

=item output_cgi_header ()

Outputs the CGI header for an HTML document.

=cut

sub output_cgi_header {
  my ($self) = @_;

  my $charset = $self->{CFG}{charset};
  my $cgi = $self->cgi_object;

  if ($CGI::VERSION >= 2.57) {
    # This is the correct way to set the charset
    print $cgi->header('-type'=>'text/html', '-charset'=>$charset);
  }
  else {
    # However CGI.pm older than version 2.57 doesn't have the
    # -charset option so we cheat:
    print $cgi->header('-type' => "text/html; charset=$charset");
  }
}

=item output_style_element ()

Outputs the C<link rel=stylesheet> header line, if a style sheet URL is
configured.

=cut

sub output_style_element {
  my ($self) = @_;

  if ($self->{CFG}{style}) {
    print qq|<link rel="stylesheet" type="text/css" href="$self->{CFG}{style}" />\n|;
  }
}

=item cgi_object ()

Returns a reference to the C<CGI.pm> object for this request.

=cut

sub cgi_object {
  my ($self) = @_;

   return $self->{CGI};
}

=item param ( ARGS )

Invokes the param() method of the C<CGI.pm> object for this request.

=cut

sub param {
    my $self = shift;

    $self->cgi_object->param(@_);
}

=item escape_html ( INPUT )

Returns a copy of the string INPUT with all HTML metacharacters escaped.

=cut

sub escape_html {
  my ($self, $input) = @_;

  return $self->{Charset}->escape($input);
}

=item strip_nonprint ( INPUT )

}

=item format_date ( FORMAT_STRING [,GMT_OFFSET] )

Returns the current time and date formated by C<strftime> according
to the format string FORMAT_STRING.

If GMT_OFFSET is undefined or the empty string then local time is
used.  Otherwise GMT is used, with an offset of GMT_OFFSET hours.

=cut

sub format_date {
  my ($self, $format_string, $gmt_offset) = @_;

  if (defined $gmt_offset and length $gmt_offset) {
    return strftime $format_string, gmtime(time + 60*60*$gmt_offset);
  }
  else {
    return strftime $format_string, localtime;
  }
}

=item name_and_version ()

Returns the NMS script version string that was passed to the constructor.

=cut

sub name_and_version {
    my ($self) = @_;

    return $self->{CFG}{name_and_version};
}

=item warn ( MESSAGE )

Appends a message to the web server's error log.

        $msg = "[$1] $msg";
    }

    warn "$msg\n";
}

=back

=head1 VIRTUAL METHODS

Subclasses for individual NMS scripts must provide the following
methods:

=over

=item default_configuration ()

Invoked from new(), this method must return the default script
configuration as a key,value,key,value list.  Configuration options
passed to new() will override those set by this method.

=item init ()

Invoked from new(), this method can be used to do any script specific
object initialisation.  There is a default implementation, which does
nothing.

=cut

sub init {}

=item handle_request ()

Invoked from request(), this method is responsible for performing the
bulk of the CGI processing.  Any fatal errors raised here will be
trapped and treated according to the C<DEBUGGING> configuration setting.

=head1 DESCRIPTION

This module provides methods to validate some of the types of
data the occur in CGI scripts, such as URLs and email addresses.

=head1 METHODS

These C<validate_*> methods all return undef if the item passed
in is invalid, otherwise they return the valid item.

Some of these methods attempt to transform invalid input into valid
input (for example, validate_abs_url() will prepend http:// if missing)
so the returned valid item may not be the same as that passed in.

The returned value is always detainted.

}

=item validate_local_abs_uri_frag ( URIFRAG )

Validates a local absolute URI fragment, such as C</img/foo.png>.  Allows
a query string.  The empty string is considered to be a valid URI fragment.

=cut

    );
  }

  $script->request;

=head1 DESCRIPTION

This module implements the NMS plugin replacement for Matt Wright's
Reservecode.pl CGI script.

=head1 CONFIGURATION SETTINGS

As well as the generic NMS script configuration settings described in
L<CGI::NMS::Script>, the Reservecode constructor recognizes the following
configuration settings:

=over

=item C<allow_empty_ref>

Some web proxies and office firewalls may strip certain headers from the
HTTP request that is sent by a browser.  Among these is the HTTP_REFERER
that Reservecode uses as an additional check of the requests validity - this
will cause the program to fail with a 'bad referer' message even though the
configuration seems fine.

In these cases, setting this configuration setting to 1 will stop the
program from complaining about requests where no referer header was sent
while leaving the rest of the security features intact.

Default: 1

=item C<max_recipients>

The maximum number of e-mail addresses that any single form should be
allowed to send copies of the e-mail to.  If none of your forms send
e-mail to more than one recipient, then we recommend that you improve
the security of Reservecode by reducing this value to 1.  Setting this
configuration setting to 0 removes all limits on the number of recipients
of each e-mail.

Default: 5

=item C<mailprog>

The system command that the script should invoke to send an outgoing email.
This should be the full path to a program that will read a message from
STDIN and determine the list of message recipients from the message headers.
Any switches that the program requires should be provided here.

For example:

  'mailprog' => '/usr/lib/sendmail -oi -t',

An SMTP relay can be specified instead of a sendmail compatible mail program,
using the prefix C<SMTP:>, for example:

  'mailprog' => 'SMTP:mailhost.your.domain',

Default: C<'/usr/lib/sendmail -oi -t'>

=item C<postmaster>

The envelope sender address to use for all emails sent by the script.

Default: ''

=item C<referers>

This configuration setting must be an array reference, holding a list  
of names and/or IP address of systems that will host forms that refer
to this Reservecode.  An empty array here turns off all referer checking.

Default: []

=item C<allow_mail_to>

This configuration setting must be an array reference.

A list of the email addresses that Reservecode can send email to. The
elements of this list can be either simple email addresses (like
'you@your.domain') or domain names (like 'your.domain'). If it's a
domain name then any address at that domain will be allowed.

Default: []

=item C<recipients>

This configuration setting must be an array reference.

A list of Perl regular expression patterns that determine who the
script will allow mail to be sent to in addition to those set in
C<allow_mail_to>.  This is present only for compatibility with the
original Reservecode script.  We strongly advise against having anything
in C<recipients> as it's easy to make a mistake with the regular
expression syntax and turn your Reservecode into an open SPAM relay.

Default: []

=item C<recipient_alias>

This configuration setting must be a hash reference.

A hash for predefining a list of recipients in the script, and then
choosing between them using the recipient form field, while keeping
all the email addresses out of the HTML so that they don't get
collected by address harvesters and sent junk email.

For example, suppose you have three forms on your site, and you want
each to submit to a different email address and you want to keep the
addresses hidden.  You might set up C<recipient_alias> like this:

  %recipient_alias = (
    '1' => 'one@your.domain',
    '2' => 'two@your.domain',
    '3' => 'three@your.domain',
  );

In the HTML form that should submit to the recipient C<two@your.domain>,
you would then set the recipient with:

  <input type="hidden" name="recipient" value="2" />

Default: {}

=item C<valid_ENV>

This configuration setting must be an array reference.

A list of all the environment variables that you want to be able to
include in the email.

Default: ['REMOTE_HOST','REMOTE_ADDR','REMOTE_USER','HTTP_USER_AGENT']

=item C<date_fmt>

The format that the date will be displayed in, as a string suitable for
passing to strftime().

Default: '%A, %B %d, %Y at %H:%M:%S'

=item C<date_offset>

The empty string to use local time for the date, or an offset from GMT
in hours to fix the timezone independent of the server's locale settings.

Default: ''

=item C<no_content>

If this is set to 1 then rather than returning the HTML confirmation page
or doing a redirect the script will output a header that indicates that no
content will be returned and that the submitted form should not be
replaced.  This should be used carefully as an unwitting visitor may click
the submit button several times thinking that nothing has happened.

Default: 0

=item C<double_spacing>

If this is set to 1 then a blank line is printed after each form value in
the e-mail.  Change this value to 0 if you want the e-mail to be more
compact.

Default: 1

=item C<join_string>

If an input occurs multiple times, the values are joined to make a
single string value.  The value of this configuration setting is
inserted between each value when they are joined.

Default: ' '

=item C<wrap_text>

If this is set to 1 then the content of any long text fields will be
wrapped at around 72 columns in the e-mail which is sent.  The way that
this is done is controlled by the C<wrap_style> configuration setting.

Default: 0

=item C<wrap_style>

If C<wrap_text> is set to 1 then if this is set to 1 then the text will
be wrapped in such a way that the left margin of the text is lined up
with the beginning of the text after the description of the field -
that is to say it is indented by the length of the field name plus 2.

If it is set to 2 then the subsequent lines of the text will not be
indented at all and will be flush with the start of the lines.  The
choice of style is really a matter of taste although you might find
that style 1 does not work particularly well if your e-mail client
uses a proportional font where the spaces of the indent might be
smaller than the characters in the field name.

Default: 1

=item C<address_style>

If C<address_style> is set to 0 then the full address for the user who filled
in the form will be used as "$email ($realname)" - this is also what the
format will be if C<emulate_matts_code> is true.

If it is set to 1 then the address format will be "$realname <$email>".

Default: 0

=item C<force_config_*>

Configuration settings of this form can be used to fix configuration
settings that would normally be set in hidden form fields.  For
example, to force the email subject to be "Foo" irrespective of what's
in the C<subject> form field, you would set:

  'force_config_subject' => 'Foo',

Default: none set

=item C<include_config_*>

Configuration settings of this form can be used to treat particular
configuration inputs as normal data inputs as well as honoring their
special meaning.  For example, a user might use C<include_config_email>
to include the email address as a regular input as well as using it in
the email header.

Default: none set

=head1 COMPILE TIME METHODS

These methods are invoked at CGI script compile time only, so long as
the new() call is placed inside a BEGIN block as shown above.

=over

  );
}

=item init ()

Invoked from the new() method inherited from L<CGI::NMS::Script>,
this method performs Reservecode specific initialization of the script
object.

=cut

sub init {
  my ($self) = @_;

  if ($self->{CFG}{wrap_text}) {

=item init_allowed_address_list ()

Invoked from init(), this method sets up a hash with a key for each
allowed recipient email address as C<Allow_Mail> and a hash with a
key for each domain at which any address is allowed as C<Allow_Domain>.

=cut

  push @allow_mail, grep /\@/, @alias_targets;

  # The username part of email addresses should be case sensitive, but the
  # domain name part should not.  Map all domain names to lower case for
  # comparison.
  my (%allow_mail, %allow_domain);
  foreach my $m (@allow_mail) {
    $m =~ /^([^@]+)\@([^@]+)$/ or die "internal failure [$m]";

}

=back

=head1 RUN TIME METHODS

These methods are invoked at script run time, as a result of the call
to the request() method inherited from L<CGI::NMS::Script>.

=over

=item handle_request ()

Handles the core of a single CGI request, outputting the HTML success
or error page or redirect header and sending emails.

Dies on error.

=cut

sub handle_request {

  $self->send_main_email($date, $email, $realname);
  $self->send_conf_email($date, $email, $realname);

  $self->success_page($date);
}

=item date_string ()

Returns a string giving the current date and time, in the configured
format.

=cut

  my ($self) = @_;

  return $self->format_date( $self->{CFG}{date_fmt},
                             $self->{CFG}{date_offset} );
}

=item referer_is_ok ( REFERER )

Returns true if the referer is OK, false otherwise.

=cut

sub referer_is_ok {
  my ($self, $referer) = @_;

  unless ($referer) {
    return ($self->{CFG}{allow_empty_ref} ? 1 : 0);
  }

  if ($referer =~ m!^https?://([^/]*\@)?([\w\-\.]+)!i) {
    my $refhost = $2;
    return $self->refering_host_is_ok($refhost);
  }
  else {
    return 0;
  }
}

=item refering_host_is_ok ( REFERING_HOST )

Returns true if the host name REFERING_HOST is on the list of allowed
referers, or resolves to an allowed IP address.

=cut

sub refering_host_is_ok {
  my ($self, $refhost) = @_;

  my @allow = @{ $self->{CFG}{referers} };
  return 1 unless scalar @allow;

  foreach my $test_ref (@allow) {

      return 1;
    }
  }

  my $ref_ip = inet_aton($refhost) or return 0;

Here's your problem, you're missing the "action" in your html. You currently have:

Code: [Select]
<form action="" method="post" enctype="multipart/form-data" name="reserve">

When it should be:

Code: [Select]
<form action="/cgi-bin/filename.pl" method="post" enctype="multipart/form-data" name="reserve">

Replace "filename.pl" with whatever you named the script.

Also, this forum probably truncates the bottom portion of the script because you are missing a chunk of code.  So, double-check that you have the entire script in your actual file.  Check the bottom of the script with the original one.

Okay, now we can narrow it down better.  Do you have Spam Assassin running? If you do, put your domain name or your email addy in the white-list.

I made a copy of your form and the script, and I get the results email sent to me, so it has to be something with an email/spam filter on your end.

I'm running spam inspector, but I checked my quarantined mail and there was nothing there.  SBC also has a spam filter, so I checked my bulk mailbox, and again nothing from my domain or anything that looked remotely like what I'm hoping for.

When I send myself an email at that address, it arrives just fine.  But it's interesting that you got it to work...

Hmmmm, do this:

Go to cPanel.  Click on "File Manager".
Click on the folder icon of the "Mail" folder
Click on the folder icon of your domain name folder
Click on the folder icon of the "Jeffrey" folder
Click on the filename "inbox"
In the upper right hand corner, click on "Show file"

Look to see if you can see the email in there?

I'm going to put your email addy in the script that is on my server.  Let's see if you get the email when I send it from my server. I'll post again when it's sent.
