<h2>Problem Reporting Guidelines </h2>
<i>"Let me see if I can translate your message into a real-world
example. It would be like saying that you have three rooms at home,
and when you walk into one of the rooms, you detect this strange smell.
Can anyone tell you what that strange smell is?<br>
<br>
Now, all of us could do some wonderful guessing as to the
smell and even what's causing it. You would be absolutely amazed at
the range and variety of smells we could come up with. Even more amazing
is that all of the explanations for the smells would be completely plausible."<br>

<h3> </h3>
<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>
<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.</b><br>
<br>
</li>
</ul>
</ul>
<ul>
<li><b>NEVER </b>include the output of "<b><font
color="#009900">iptables -L</font></b>". Instead, <b>if you are having
connection problems of any kind</b>, post the exact output of<br>
<br>
<b><font color="#009900">/sbin/shorewall status<br>
<br>
</font></b>Since that command generates a lot of output, we
suggest that you redirect the output to a file and attach the file to
your post<br>
<br>
<b><font color="#009900">/sbin/shorewall status &gt; /tmp/status.txt</font></b><br>
<br>
</li>
<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).<strong></strong></li>
</ul>
<ul>
</ul>
<h3> </h3>
<ul>
</ul>
<h3> </h3>
<ul>
<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). </li>
</ul>
<h3> </h3>
<ul>
</ul>
<h3> </h3>
<ul>
<li> If an error occurs
when you try to "<font color="#009900"><b>shorewall start</b></font>",
include a trace (See the <a href="troubleshoot.htm">Troubleshooting</a>
section for instructions). </li>
</ul>

The author gratefully acknowleges that the above list was heavily
plagiarized from the excellent LEAF document by <i>Ray</i> <em>Olszewski</em>

<h2>Please post in plain text</h2>
<blockquote> </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>
