Samba file sharing service configuration and user mapping in Linux

About Samba Services

Samba is a free software that implements the SMB protocol on Linux and UNIX systems, consisting of servers and client programs. SMB (Server Messages block, information service blocks) is a kind of communication protocol for sharing files and printers on LAN, which provides shared services of files and printers among different computers in LAN. The SMB protocol is a client/server protocol that allows clients to access shared file systems, printers, and other resources on the server. By setting up "NetBIOS over TCP/IP", Samba will not only share resources with local network hosts, but also share resources with computers around the world.

Identify two machines connected to each other

Anonymous configuration steps

First install Samba

# rpm-ivh/sr0/packages/samba-3.6.9-164.el6.x86_64.rpm

Adjusting the configuration file

To be safe, back up the configuration file first

# MV Smb.conf SMB.CONF.BK

# grep-v "#" SMB.CONF.BK > smb.conf

Start modifying

#vim smb.conf

Anonymous access

Access settings

Change folder permissions

# chmod 777/opt/a

Shutting down firewalls and SELinux

Start the service

Errors that may occur during the process

1. When the client logs on to samba, the following prompt appears: Session setup failed:nt_status_logon_failure The error indicates that the user is wrong, either the user does not exist or the password is incorrect. Or just in the Samba user and system user and password errors, in short, the user and password issues. Tree Connect Failed:nt_status_bad_network_name This error indicates a bad network name, indicates that the shared directory does not exist, or the shared directory permissions issue is available setfacl-m to the user with permission connection to 192.168.4.7 failed (Error nt_status_host_unreachable) 2. The following prompt appears when the client connects to the Samba shared directory: SMB: \> lsnt_status_access_denied Listing \* file permissions are insufficient, or there is a selinux limit to adjust the file permissions, and open SELinux switch 3, perform setsebool-p operation to enable the SELinux switch parameter failure, prompt: Killed memory is low, And there's not enough swap space. Add swap partition (1GB) in retry
