Windows Interoperability

What can Samba do?

Allow for peaceful coexistence between Windows and Linux/UNIX systems regarding: File sharing Printer sharing Distributed Filesystem sharing Client Authentication Provide/Assist with Windows Internet Name

Service (WINS)

How does Samba do it?

SMB = Server Message Block SMB is an extension added by MS to allow DOS

to redirect calls to NetBIOS NetBIOS = (crude) interface between network

and application CIFS = Common Internet File System

Different paradigm than NFS Based on protocols from SMB

SMBFS Allows Linux to treat CIFS just as another foreign

FS

Why care about Windoze?

Its everywhere (dun dun DUN!) Chances are, more of your clients will be

using it than *NIX It has brought computing to the average

Joe billions of em It uses inferior multi-user technology,

and we should help them where possible Its not leaving anytime soon get over it

Everybody dance now. (p798) Samba runs as a service; usually needs

little attention Can check using smbstatus

Only config file: /etc/samba/smb.conf Two daemons

smbd file and print services, authentication

nmbd NetBIOS name service, browsing

What will Samba do here?

Can do File sharing Printer sharing Distributed Filesystem sharing Client Authentication Provide/Assist with Windows Internet Name

Service (WINS) Backup PCs (smbtar)

Will do only setup of file sharing today

File Sharing Setup

Install Samba V2 series: 2.2.8a latest V3 series: 3.0.2a latest

Modify /etc/samba/smb.conf Add users and set passwords

Add user using useradd Set user password using passwd Set Samba password using smbpasswd

Restart Samba /etc/rc.d/init.d/smb restart

/etc/samba/smb.conf

Standard, simple scheme[share]

attribute = value# or ; denotes a comment Sample Headings:

global global settings, network IDs homes users home directories printers printing utilities Music mp3 and other audio files everyone open RW share to all

Shares and Attributes

global workgroup = name of Windows network group netbios name = name to appear in Windows Network

Neighborhood hosts allow = list of IPs (whitespace-delineated) to have

access to SMB shares encrypt passwords = yes, for Win98+; no for Win95-

homes browseable = yes, will map directly to /home/user; much

like My Documents ability on campus writable = yes (same as read only = no); by default,

all shares are read-only

Common Shares and Attributes Music

path = path to music files public = yes, will allow RX access to all users write list = list of users that can write invalid users = list of users that cannot access

Note: users are names from Windows logon, and are case-insensitive.

everyone path = path to RW storage space Often also set read only = no and browseable = yes Note: gives full RW access to anyone be careful

printers printable = yes path = /var/spool/samba

Accessing Samba/Win Shares

From Windows Using Network Neighborhood Act and look like normal shares

From Linux/UNIX Using a file manager (like Konqueror)

Often very slow, requires re-entering of passwords Using network app like Komba2 or

LinNeighborhood Mount them

in /etc/fstab //SMB_server/share local_mount_dir smbfs options 0 0

mount t smbfs o username=name //SMB_server/share mount_dir

Egotistical Reasons

So you dont feel like sharing with others?

SMBFS now allows RW access to NTFS Can have fully-functional and non-exclusive

dual-boot machines Do not have to lose resources (printers,

files, etc.) when developing under Linux or Win

Resources

Plenty available, including books 100s of pages long just on Samba! http://www.mandrakeuser.org/docs/connect/

csamba.html http://www.samba.netfirms.com/index.htm http://www.samba.org

Tons of documentation, including Using Sambaby OReilly, all online

Miscellaneous Issues

Useful Windows tools ssh clients X- Windows emulators

Dual-booting Running Windows under Linux or vice versa
