1. Introduction


SAMBA is a SMB/CIFS protocols file and print sharing server/client set originaly

made for UNIX world to cooperate with corresponding Windows and OS/2 servers or

clients. OS/2 has native implementation of SMB/CIFS server/client set - IBM LAN

Manager and IBM Peer. These products haven't been updated for a long time and

have some compatibility problems with modern Windows SMB/CIFS implementations.

This package is the OS/2 port of SAMBA 3.0.27a client made as the plugin to

NetDrive - a well known virtual file system for OS/2. OS/2 SAMBA client provides

seamless access to SMB/CIFS file shares over your network using TCP/IP as the

underlying transport protocol.

The OS/2 SAMBA client consists of two modules:

   ndpsmb.dll - the NetDrive plugin itself.

   smbcd.exe  - the SAMBA client daemon, which actually processes the requests

                from ndpsmb.dll.

3. Installation


You must have NetDrive 2.2.1 or newer installed prior to installation of this

package. If you want to use 64bit file API, you should install 2.3 or newer

version of NetDrive. The installation is semi-automatic and consists of two 


  - libc installation :

      Put libc063.dll available from ftp://ftp.netlabs.org/pub/gcc/libc-0.6.3-csd3.zip (the kLibc gcc runtime dll) somewhere in your LIBPATH, if it is not here already.

  - ndpsmb.dll and smbcd.exe installation :

      Run instpl.cmd from this package. The installer will place smbcd.exe in 

      the Netdrive home directory. When you will connect to CIFS share using the

      ndpsmb plugin, it will start the smbcd.exe  automatically from this 

      directory. However, you can start it manually, if you want.

4. SMBCD.EXE Usage


SMBCD.EXE has the following parameters:

  -d <debuglevel> (or --debug <debuglevel>) - debug level of output from 0 to 9.

The more debug level provides more debugging output from SMBCD.EXE which may 

be used to solve the problems.

  -l <logfile> (or --logfile <logfile>) - the filename to write the debug info

from smbcd.exe. Default is to print all debug info to STDOUT stream.

  -q (or --quiet) - tells smbcd.exe to be absolutely quiet.



NetDrive SAMBA plugin is used according to general NetDrive usage rules. Read

the NetDrive documentation for more information. The SMB/CIFS resources could

be mounted either using command line nd.exe utility or WPS ndpm.exe utility of


The NetDrive SAMBA plugin parameters are:

   workgroup   - the name of workgroup to connect to.

   server      - the name of server to connect to.

   share       - the name of server resource (share) to connect to.

   user        - the name of user to login under.

   password    - the password of selected user.

   master      - the name of 'master' server or workgroup, used to get the list

                 of workgroups when the concrete workgroup and server not


   masterttype - 0 if 'master' is the name of master server, 1 if 'master' is

                 the name of master workgroup.

   memlen      - the size of shared memory buffer allocated for every connection

                 to SBM/CIFS resources in size of 64k blocks. The higher values

                 could provide better access speed, but consume more memory.

   logfile     - file to log records from smbcd.exe. Used only in smbcd.exe 

                 is run by ndpsmb.dll plugin, not manually

   loglevel    - level of logging (0-9) for smbcd.exe. Used only in smbcd.exe 

                 is run by ndpsmb.dll plugin, not manually

   easupport   - 1 to support OS/2 Extended Attributes, 0 to not support it

To mount the a exact server's share one need to specify both 'server' and

'share' parametres, the other parametres are optional. The root path of

server's share will be mounted to the mounting path.

If one want to access all servers shares, the only the 'server', not the 'share'

parameter, should be specified,the other parametres are optional. The list of

server's shares will be mounted to the mounting path.

If one want to access all servers within the workgroup, the only the 'workgroup',

not the 'server' parameter, should be specified, the other parametres are

optional. The list of servers within the specified workgroup will be mounted to

the mounting path.

If one want to access all available workgroups within one master browser

in network, the only the 'master', not the 'workgroup' or 'server' parameter,

should be specified, the other parametres are optional. The list of workgroups

will be mounted to the mounting path. The 'master' workgroup can be any known

workgroup in the net. The 'master' server should be the master browser for


By default the 'guest' user with blank password is used to access selected

resources. If you get access denied (5) errors, try to specify another user and

password combination.
