This guide explains how to configure samba server in Ubuntu 14.04 with anonymous & secured samba servers. Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
I have fresh installed ubuntu14.04 server, on which I am going to install the samba server. Off-course you need to have one windows machine to check the samba server that must be reachable with the ubuntu server. My ubuntu server have hostname server1.example.com & IP as 192.168.0.100
You can have your ubuntu server installed from the starting eleven chapters of this tutorial.
- The Windows machine must be on same workgroup. To check the value in windows machine run the command at cmd prompt
net config workstation
It will be like this
Your windows machine must be at same Workstation domain as in ubuntu server, i.e. WORKGROUP in my case.
- To make the windows machine reachable in windows proceed like this. In the run terminal & add the entry of your server IP address
In my case it was like this, just save the values.
[...] 192.168.0.100 server1.example.com ubuntu
2 Anonymous samba sharing
First I will explain the methodology to install the samba with the anonymous sharing. To install samba run,
apt-get install samba samba-common python-glade2 system-config-samba
It will install samba with version 4.1.6-Ubuntu.
Now to configure samba edit the file /etc/samba/smb.cnf before making changes I will make the backup of original file as /etc/samba/smb.cnf.bak
mv /etc/samba/smb.cnf /etc/samba/smb.cnf.bak
Further give the entries like this
[global] workgroup = WORKGROUP server string = Samba Server %v netbios name = ubuntu security = user map to guest = bad user dns proxy = no #============================ Share Definitions ============================== [Anonymous] path = /samba/anonymous browsable =yes writable = yes guest ok = yes read only = no
mkdir -p /samba/anonymous
service smbd restart
Now you can access the ubuntu sharing in windows as follows:
From windows machine just browse the folder& try to create a text file, but you will get an error of permission denied.
Check the permission for the shared folder.
root@server1:~# ls -l /samba/
drwxr-xr-x 2 root root 4096 May 27 18:17 anonymous
To allow anonymous user give the permissions as follows;
root@server1:~# cd /samba
root@server1:/samba# chmod -R 0755 anonymous/
root@server1:# chown -R nobody:nogroup anonymous/
root@server1:/samba# ls -l
drwx-xr-x 2 nobody nogroup root 4096 May 27 18:17 anonymous
Now anonymous user can browse & create the folder contents.
You can cross check the content at server also.
root@server1:/samba# ls -l anonymous/
-rwxr–r– 1 nobody nogroup 0 May 27 18:30 test_samba.txt
3. Secured samba server
For this I will create a group smbgrp & user srijan to access the samba server with proper authentication
adduser srijan -G smbgrp
smbpasswd -a srijan
root@server1:~# smbpasswd -a srijan
New SMB password:
Retype new SMB password:
Added user srijan.
Now create the folder viz secured in the /samba folder & give permissions like this
mkdir -p /samba/secured
chmod -R 0770 secured/
Again edit the configuration file as :
[secured] path = /samba/secured valid users = @smbgrp guest ok = no writable = yes browsable = yes
service smbd restart
Further to cross-check the settings check as follows:
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section “[Anonymous]”
Processing section “[secured]”
Loaded services file OK.
Server role: ROLE_STANDALONE
Press enter to see a dump of your service definitions
Now at windows machine check the folder now with the proper credentials
You will again face the issue of permissions to give write permission to the user srijan do:
chown -R srijan:smbgrp secured/
Now samba user srijan have permissions to write in the folder. Cheers you have done with samba server in Ubuntu14.04.
