Also, please see if it has changed between releases, as we -may be changing the bug reporting mechanism at some time. -</p><p> -Please also do as much as you can yourself to help track down the -bug. Samba is maintained by a dedicated group of people who volunteer -their time, skills and efforts. We receive far more mail about it than -we can possibly answer, so you have a much higher chance of an answer -and a fix if you send us a "developer friendly" bug report that lets -us fix it fast. -</p><p> -Do not assume that if you post the bug to the comp.protocols.smb -newsgroup or the mailing list that we will read it. If you suspect that your -problem is not a bug but a configuration problem then it is better to send -it to the Samba mailing list, as there are (at last count) 5000 other users on -that list that may be able to help you. -</p><p> -You may also like to look though the recent mailing list archives, -which are conveniently accessible on the Samba web pages -at <a href="http://samba.org/samba/" target="_top">http://samba.org/samba/</a>. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2960681"></a>General info</h2></div></div><div></div></div><p> -Before submitting a bug report check your config for silly -errors. Look in your log files for obvious messages that tell you that -you've misconfigured something and run testparm to test your config -file for correct syntax. -</p><p> -Have you run through the <a href="diagnosis.html" title="Chapter 33. The Samba checklist">diagnosis</a>? -This is very important. -</p><p> -If you include part of a log file with your bug report then be sure to -annotate it with exactly what you were doing on the client at the -time, and exactly what the results were. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2960718"></a>Debug levels</h2></div></div><div></div></div><p> -If the bug has anything to do with Samba behaving incorrectly as a -server (like refusing to open a file) then the log files will probably -be very useful. Depending on the problem a log level of between 3 and -10 showing the problem may be appropriate. A higher level gives more -detail, but may use too much disk space. -</p><p> -To set the debug level use the <a class="indexterm" name="id2960739"></a><i class="parameter"><tt>log level</tt></i> in your -<tt class="filename">smb.conf</tt>. You may also find it useful to set the log -level higher for just one machine and keep separate logs for each machine. -To do this add the following lines to your main <tt class="filename">smb.conf</tt> file: -</p><table class="simplelist" border="0" summary="Simple list"><tr><td><i class="parameter"><tt>log level = 10</tt></i></td></tr><tr><td><i class="parameter"><tt>log file = /usr/local/samba/lib/log.%m</tt></i></td></tr><tr><td><i class="parameter"><tt>include = /usr/local/samba/lib/smb.conf.%m</tt></i></td></tr></table><p> -then create a file -<tt class="filename">/usr/local/samba/lib/smb.conf.<i class="replaceable"><tt>machine</tt></i></tt> where -<i class="replaceable"><tt>machine</tt></i> is the name of the client you wish to debug. In that file -put any <tt class="filename">smb.conf</tt> commands you want, for example -<a class="indexterm" name="id2960830"></a><i class="parameter"><tt>log level</tt></i> may be useful. This also allows you to -experiment with different security systems, protocol levels etc on just -one machine. -</p><p> -The <tt class="filename">smb.conf</tt> entry <a class="indexterm" name="id2960857"></a><i class="parameter"><tt>log level</tt></i> -is synonymous with the parameter <a class="indexterm" name="id2960872"></a><i class="parameter"><tt>debuglevel</tt></i> that has -been used in older versions of Samba and is being retained for backwards -compatibility of <tt class="filename">smb.conf</tt> files. -</p><p> -As the <a class="indexterm" name="id2960897"></a><i class="parameter"><tt>log level</tt></i> value is increased you will record -a significantly increasing level of debugging information. For most -debugging operations you may not need a setting higher than -<tt class="constant">3</tt>. Nearly -all bugs can be tracked at a setting of <tt class="constant">10</tt>, but be -prepared for a VERY large volume of log data. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2960926"></a>Internal errors</h2></div></div><div></div></div><p> -If you get a <span class="errorname">INTERNAL ERROR</span> message in your log files -it means that Samba got an unexpected signal while running. It is probably a -segmentation fault and almost certainly means a bug in Samba (unless -you have faulty hardware or system software). -</p><p> -If the message came from smbd then it will probably be accompanied by -a message which details the last SMB message received by smbd. This -info is often very useful in tracking down the problem so please -include it in your bug report. -</p><p> -You should also detail how to reproduce the problem, if -possible. Please make this reasonably detailed. -</p><a class="indexterm" name="id2960962"></a><p> -You may also find that a core file appeared in a <tt class="filename">corefiles</tt> -subdirectory of the directory where you keep your samba log -files. This file is the most useful tool for tracking down the bug. To -use it you do this: -</p><a class="indexterm" name="id2960984"></a><a class="indexterm" name="id2960993"></a><pre class="screen"> -<tt class="prompt">$ </tt><b class="userinput"><tt>gdb smbd core</tt></b> -</pre><p> -adding appropriate paths to smbd and core so gdb can find them. If you -don't have gdb then try <b class="userinput"><tt>dbx</tt></b>. Then within the debugger -use the command <b class="command">where</b> to give a stack trace of where the -problem occurred. Include this in your report. -</p><p> -If you know any assembly language then do a -<b class="command">disass</b> of the routine -where the problem occurred (if its in a library routine then -disassemble the routine that called it) and try to work out exactly -where the problem is by looking at the surrounding code. Even if you -don't know assembly, including this info in the bug report can be -useful. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2961060"></a>Attaching to a running process</h2></div></div><div></div></div><p> -Unfortunately some unixes (in particular some recent linux kernels) -refuse to dump a core file if the task has changed uid (which smbd -does often). To debug with this sort of system you could try to attach -to the running process using -<b class="userinput"><tt>gdb smbd <i class="replaceable"><tt>PID</tt></i></tt></b> where you get -<i class="replaceable"><tt>PID</tt></i> from <span class="application">smbstatus</span>. -Then use <b class="command">c</b> to continue and try to cause the core dump -using the client. The debugger should catch the fault and tell you -where it occurred. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2961107"></a>Patches</h2></div></div><div></div></div><a class="indexterm" name="id2961114"></a><a class="indexterm" name="id2961123"></a><p> -The best sort of bug report is one that includes a fix! If you send us -patches please use <b class="userinput"><tt>diff -u</tt></b> format if your version of -diff supports it, otherwise use <b class="userinput"><tt>diff -c4</tt></b>.
