See the man pages on smbd, nmbd and +smb.conf for more information on debugging options. The debug +level can range from 1 (the default) to 10 (100 for debugging passwords). +</para> + +<para> +Another helpful method of debugging is to compile samba using the +<command>gcc -g </command> flag. 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 gdb attach and continue. +</para> + +<para> +Some useful samba commands worth investigating: +</para> + +<itemizedlist> + <listitem><para>testparam | more</para></listitem> + <listitem><para>smbclient -L //{netbios name of server}</para></listitem> +</itemizedlist> + +<para> +An SMB enabled version of tcpdump is available from +<ulink url="http://www.tcpdump.org/">http://www.tcpdup.org/</ulink>. +Ethereal, another good packet sniffer for Unix and Win32 +hosts, can be downloaded from <ulink +url="http://www.ethereal.com/">http://www.ethereal.com</ulink>. +</para> + +<para> +For tracing things on the Microsoft Windows NT, Network Monitor +(aka. netmon) is available on the Microsoft Developer Network CD's, +the Windows NT Server install CD and the SMS CD's.
