<h2>Problem Reporting Guidelines<br>
</h2>
<ul>
<li>Please remember we only know
what is posted in your message. Do not leave out any information
that appears to be correct, or was mentioned in a previous
post. There have been countless posts by people who were sure
that some part of their configuration was correct when it actually
contained a small error. We tend to be skeptics where detail
is lacking.<br>
<br>
</li>
<li>Please keep in mind that you're
asking for <strong>free</strong> technical support.
Any help we offer is an act of generosity, not an obligation.
Try to make it easy for us to help you. Follow good, courteous
practices in writing and formatting your e-mail. Provide details that
we need if you expect good answers. <em>Exact quoting </em> of
error messages, log entries, command output, and other output is better
than a paraphrase or summary.<br>
<br>
</li>
<li>
Please don't describe your environment and then ask
us to send you custom configuration files. We're
here to answer your questions but we can't do
your job for you.<br>
<br>
</li>
<li>When reporting a problem, <strong>ALWAYS</strong>
include this information:</li>
</ul>
<ul>
<ul>
<li>the exact version of Shorewall
you are running.<br>
<br>
<b><font color="#009900">shorewall
version</font><br>
</b> <br>
</li>
</ul>
<ul>
<li>the exact kernel version you
are running<br>
<br>
<font color="#009900"><b>uname
-a<br>
<br>
</b></font></li>
</ul>
<ul>
<li>the complete, exact output
of<br>
<br>
<font color="#009900"><b>ip
addr show<br>
<br>
</b></font></li>
</ul>
<ul>
<li>the complete, exact output
of<br>
<br>
<font color="#009900"><b>ip
route show<br>
<br>
</b></font></li>
</ul>
<ul>
<li>If your kernel is modularized,
the exact output from<br>
<br>
<font color="#009900"><b>lsmod</b></font><br>
</li>
</ul>
</ul>
<ul>
<ul>
<li><font color="#ff0000"><u><i><big><b>If you are having
connection problems of any kind then:</b></big></i></u></font><br>
<br>
1. <b><font color="#009900">/sbin/shorewall reset</font></b><br>
<br>
2. Try the connection that is failing.<br>
<br>
3.<b><font color="#009900"> /sbin/shorewall status
&gt; /tmp/status.txt</font></b><br>
<br>
4. Post the /tmp/status.txt file as an attachment.<br>
<br>
</li>
<li>the exact wording of any <code
style="color: green; font-weight: bold;">ping</code> failure responses<br>
<br>
</li>
<li>If you installed Shorewall using one of the QuickStart
Guides, please indicate which one. <br>
<br>
</li>
<li><b>If you are running Shorewall under Mandrake using
the Mandrake installation of Shorewall, please say so.<br>
<br>
</b></li>
</ul>
<li>As a general matter, please <strong>do not edit the diagnostic
information</strong> in an attempt to conceal your IP address,
netmask, nameserver addresses, domain name, etc. These aren't
secrets, and concealing them often misleads us (and 80% of the time,
a hacker could derive them anyway from information contained
in the SMTP headers of your post).<br>
<br>
<strong></strong></li>
<li>Do you see any "Shorewall" messages ("<b><font
color="#009900">/sbin/shorewall show log</font></b>") when
you exercise the function that is giving you problems? If
so, include the message(s) in your post along with a copy of your /etc/shorewall/interfaces
file.<br>
<br>
</li>
<li>Please include any of the Shorewall configuration
files (especially the /etc/shorewall/hosts file
if you have modified that file) that you think are
relevant. If you include /etc/shorewall/rules, please include
/etc/shorewall/policy as well (rules are meaningless unless
one also knows the policies).<br>
<br>
</li>
<li>If an error occurs when you try to "<font
color="#009900"><b>shorewall start</b></font>", include a trace
(See the <a href="http://www.shorewall.net/troubleshoot.htm">Troubleshooting</a>
section for instructions).<br>
<br>
</li>
<li><b>The list server limits posts to 120kb so don't
post GIFs of your network layout, etc.
to the Mailing List -- your post will be rejected.</b></li>
</ul>

<h2>When using the mailing list, please post in plain text</h2>
<blockquote> A growing number of MTAs serving list subscribers are
rejecting all HTML traffic. At least one MTA has gone so far as to
blacklist shorewall.net "for continuous abuse" because it has been
my policy to allow HTML in list posts!!<br>
<br>
I think that blocking all HTML
is a Draconian way to control spam and that the ultimate
losers here are not the spammers but the list subscribers
whose MTAs are bouncing all shorewall.net mail. As one list
subscriber wrote to me privately "These e-mail admin's need
to get a <i>(expletive deleted)</i> life instead of trying to
rid the planet of HTML based e-mail". Nevertheless, to allow
subscribers to receive list posts as must as possible, I have now
configured the list server at shorewall.net to strip all HTML from
outgoing posts.<br>
<br>
<big><font color="#cc0000"><b>If you run your own outgoing mail server
and it doesn't have a valid DNS PTR record, your email won't reach the lists
unless/until the postmaster notices that your posts are being rejected. To
avoid this problem, you should configure your MTA to forward posts to shorewall.net
through an MTA that <u>does</u> have a valid PTR record (such as the one
at your ISP). </b></font></big><br>
