This will include debug -information in the binaries and allow you to attach gdb to the -running smbd / nmbd process. In order to attach gdb to an smbd -process for an NT workstation, first get the workstation to make the -connection. Pressing ctrl-alt-delete and going down to the domain box -is sufficient (at least, on the first time you join the domain) to -generate a 'LsaEnumTrustedDomains'. Thereafter, the workstation -maintains an open connection, and therefore there will be an smbd -process running (assuming that you haven't set a really short smbd -idle timeout) So, in between pressing ctrl alt delete, and actually -typing in your password, you can attach gdb and continue. -</p><p> -Some useful samba commands worth investigating: -</p><pre class="screen"> -<tt class="prompt">$ </tt><b class="userinput"><tt>testparm | more</tt></b> -<tt class="prompt">$ </tt><b class="userinput"><tt>smbclient -L //{netbios name of server}</tt></b> -</pre></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2959894"></a>Tcpdump</h3></div></div><div></div></div><p><a href="http://www.tcpdump.org/" target="_top">Tcpdump</a> was the first -unix sniffer with SMB support.
