= =

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 / / whether to allow guest users to access

Writable = yes / / whether the shared directory is scientific or not

Printable = no / / whether to print

Write list = huahua / / users who allow write operations

Valid users = huahua / / users who are allowed to access the share

Systemctl restart smb

New user: useradd username

Set the samba password for the user: smbpasswd-a username

UGO permission: if you need the user to have permission to write, you need to set the user's w permission on the shared directory.

Client:

Windows:\\ samba server address\ share name

Linux: mount-t cifs 192.168.2.222:/pub / media-o username=huahua

The following aspects are considered when there are permission issues:

1. Program setting permissions

2.UGO permission

3.Selinux permission

Ftp file transport protocol

21 control connection command channel

20 data transmission data channel

Active mode POST

Passive mode PASV

User Type:

(1) Anonymous user: anon

(2) Local user: / etc/passwd

(3) Virtual user: map the logged-in user to a specified system account (/ sbin/nologin) to access FTP resources

/ etc/vsftpd/vsftpd.conf main configuration file

Anonymous_enable=YES / / allow anonymous access

Local_enable=YES / / allow local users to access

Vim / etc/vsftpd/ftpuser.txt

Test

(3) generate database files

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

(4) configure 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) add system users

Useradd-s / sbin/nologin ftpuser

(6) configure the main configuration file

Vim / etc/vsftpd/vsftpd.conf

Pam_service_name=vsftpd

Userlist_enable=YES

Tcp_wrappers=YES
