SAMBA PROTOCOL
Ferry Astika Saputra

2. What is SAMBA?
Provides interoperability of resources between Linux/Unix hosts and hosts running MS Windows OS.

3. How did SAMBA get started?
In early 1992, Andrew Tridgell wanted to mount a disk share from his Unix host on to a DOS PC.
Reverse engineered the SMB/NetBIOS protocol using packet sniffer.
Thus was born the SAMBA package as we know it today!
Andrew has a big team, with members across the globe contributing to the SAMBA project.
UPDATED : Common Internet File System (CIFS)

4. The TCP/IP Properties NetBIOS Name service netbios-ns 137/tcp, 137/udp
NetBIOS Datagram service netbios-dgm /tcp, 138/udp
NetBIOS Session service netbios-ssn /tcp, 139/udp
NetBIOS tunneled over TCP/IP protocol makes it routable!

5. SMB on the Network Stack

6. Functionality Provided
File and Print services
Authentication and Authorization
Name resolution
Service announcement (browsing).

7. Components File and Print services provided by smbd daemon.
Name Resolution and Browsing provided by nmbd daemon.
Name Resolution - broadcast and point-to-point.
WINS server [NBNS (NetBIOS Name Service)].
Computers in a LAN hold an election to decide the Local Master Browser (LMB).
The LMB's job is to keep a list of available services that you see in the Network Neighborhood

8. Security Levels
Share Level - single password is given to everyone who is allowed to use the share.
User Level - each user has their own username and password and the System Administrator can grant or deny access on an individual basis.

9. Configuration – Global
workgroup = SOHO-SMB
server string = Samba Server
hosts allow =
hosts deny =
printcap name = /etc/printcap
load printers = yes
printing = bsd
log file = /var/log/samba/%m.log
max log size = 0
security = user
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd

10. Configuration – HOMES [homes] comment = Home Directories
browseable = no
writable = yes

11. Configuration – Printers
comment = Printers
path = /var/spool/samba
browseable = no
writeable = no
guest ok = no
printable = yes

12. NT Domain Setup Configure encrypted passwords Parameters to be set:
domain master = yes
preferred master = yes
domain logons = yes
logon script = %U.bat - per user logon script
Configure encrypted passwords
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
Use smbpasswd -a <userid> to create encrypted passwords for Samba

14. Examples smbclient – a ftp like client to connect to a Samba server
smbclient //milkyway/homes -U jdoe
added interface ip= bcast= nmask=
Password:
Domain=[SOHO-SMB] OS=[Unix] Server=[Samba 2.2.4]
smb: \> help
smbmount/mount – mount a Samba share
mount -t smbfs -o username=jdoe //milkyway/homes /mnt/samba/
