You can easily test your Samba server for configuration errors. It check an smb.conf configuration file for internal correctness.
If this program reports no problems, you can use the configuration file with confidence that smbd will successfully load the configuration file.
Open a shell prompt. And type the following command:
# testparm /etc/samba/smb.conf
The program will issue a message saying whether the configuration file loaded OK or not. This message may be preceded by errors and warnings if the file did not load. If the file was loaded OK, the program then dumps all known service details to screen.
If testparm finds an error in the smb.conf file it returns an exit code of 1 to the calling program, else it returns an exit code of 0. This allows shell scripts to test the output from testparm.
if [ $? -eq 0 ]; then
echo "Syntax OK"
echo "Syntax Error"
