Ftp

Nfs

NFS between Linux and Linux

CIFS between Windows and Windows

SMB Service Message Block

Samba

=========================================

Server

Yum-y Install Samba

Vim/etc/samba/smb.conf

[Pub]//share name

Comment = Pub Stuff//Share description information

Path =/common//shared directory

Public = yes/allow Guest user access

writable = yes//The shared directory is a science and

printable = no//whether printing

Write list = Huahua//user to allow write operations

Valid users = Huahua//Allow access to the shared user

Systemctl Restart SMB

New User: Useradd username

Set Samba password for User: Smbpasswd-a username

Ugo permissions: If you want the user to have permission to write, you need to set the user's W permissions on the shared directory.

=====================================================================

Client:

Windows: \\samba server address \ Share name

Linux:mount-t CIFS 192.168.2.222:/pub/media-o Username=huahua

Considerations Regarding Permissions issues:

1. Program Settings permissions

2.UGO Permissions

3.Selinux Permissions

FTP File Transport protocol

21 Control Connection Command channel

20 Data transfer Channel

Active Mode POST

Passive Mode PASV

User type:

(1) Anonymous User: Anon

(2) Local Users:/etc/passwd

(3) Virtual User: Map the logged-in user to the specified system account (/sbin/nologin) to access the FTP resource

Virtual User:

(1) Install package: Yum install Pam Libdb libdb-utils

(2) Edit user password file

Vim/etc/vsftpd/ftpuser.txt

Test

(3) Generating database files

Db_load-t-T Hash-f/etc/vsftpd/ftpuser.txt/etc/vsftpd/vsftpd_login.db

(4) Configuring the Auth and Account modules

cd/etc/pam.d/

Vim VSFTPD

Auth sufficient/lib64/security/pam_userdb.so Db=/etc/vsftpd/vsftpd_login

Account Sufficient/lib64/security/pam_userdb.so Db=/etc/vsftpd/vsftpd_login

(5) Adding system users

Useradd-s/sbin/nologin Ftpuser

(6) Configuring the master configuration file

Vim/etc/vsftpd/vsftpd.conf

Pam_service_name=vsftpd

Userlist_enable=yes

Tcp_wrappers=yes

Guest_enable=yes
