  1. Workshop Administrasi Jaringan 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 138/tcp, 138/udp NetBIOS Session service netbios-ssn 139/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 [global] workgroup = SOHO-SMB server string = Samba Server hosts allow = 192.168. 1.23 hosts deny = 192.168.1.10 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 [printers] comment = Printers path = /var/spool/samba browseable = no writeable = no guest ok = no printable = yes

  12. NT Domain Setup 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=192.168.1.99 bcast=192.168.1.255 nmask=255.255.255.0 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/ Password:
