Samba Server-Introduction

The Samba server is made up of the three daemons:

nmbd

This daemon handles all name registration and resolution requests.

smbd

This daemon handles all TCP/IP-based connection services for file- and print-based operations.

winbindd

This daemon should be started when Samba is a member of a Windows NT4 or ADS domain.It will check idmap uid and idmap gid parameters in /etc/samba/smb.conf.

#testparm /etc/samba/smb.conf
to check syntax for samba configure file.

Samba Server-tdb database

#sudo smbd -b | grep PRIVATE_DIR
the best way to confirm tdb file location

#sudo smbd -b | grep LOCK_DIR
the best way to confirm tdb file location
