smbclient -L ShareWiz -N

• -L <server> option instructs smbclient to list the available resources on the server.
• -N flag (anonymous login) is used to temporarily avoid any potential problems with authentication.

This step should be executed while logged on to the Samba server locally (that is, not from another Unix host on the network).

An error message may be displayed instead:

error connecting to 192.168.1.2:139 (Connection refused)
Connection to <server> failed

This could be caused by smbd not running or not being able to bind to port 139.

An inability to bind to the correct port can be caused by configuring smbd to start from [x]inetd (possibly left over from a previous Samba installation) and then attempting to launch the server as a daemon.

The most common means of correcting this is to ensure that smbd can actually start.

Because smbd does not print error messages to the console window, it is a good idea to view the last few lines of the associated log file.

tail /var/log/samba/log.smbd

Another error message often seen is:

session request to <server> failed (Not listening for calling name)

When connecting locally using smbclient, this error is almost always a result of a misconfigured hosts allow or hosts deny parameter in smb.conf. The server is running by rejecting the NetBIOS session setup.

Check that the correct NetBIOS name was entered in the command. If that is not the cause of the error, then it could be caused by a broken nmbd installation.
