简述

>> FTP:

1. Install FTP service on Linux(Red Hat) as root user
[root]# yum install ftp

2. Configure FTP as root user

a) Be clear with below properties, and configure them in the file /etc/vsftpd/vsftpd.conf as root user

# Uncomment this to allow local users to log in.
local_enable=YES

# Uncomment this to enable any form of FTP write command.
write_enable=YES

# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd‘s)
local_umask=022

# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES

userlist_enable=YES
userlist_deny=NO

#Passive mode not allowed
pasv_enable=NO

# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES

#Specify listen port
listen_port=21

#Allow active mode
port_enable=YES

b) Make sure ftp user exists in the file /etc/vsftpd/user_list as root user

3. Restart FTP service as root user
[root]# service vsftpd restart

>> SFTP:
Generally SFTP service is installed/configured on Linux OS

>> Please refer to below info:
假设ftpserver没有开通20。可是FTPserver开通了高位随机port，则必须使用被动模块，同一时候也能够使用主动模式。
假设客服端的防火墙关闭了port的主动接收功能，则无法使用主动模式。但能够使用被动模块，这也是被动模块存在的原因。

一般公司内部为了server安全点。使用主动模式，但对client有些要求，能够接受port的请求数据。

PORT（主动）方式的连接过程是：
client向server的FTPport（默认是21）发送连接请求，server接受连接。建立一条命令链路。
当须要传送数据时，client在命令链路上用PORT命令告诉server：“我打开了****port，你过来连接我”。
于是server从20port向client的****port发送连接请求，建立一条数据链路来传送数据。

PASV（被动）方式的连接过程是：
client向server的FTPport（默认是21）发送连接请求，server接受连接。建立一条命令链路。
当须要传送数据时。server在命令链路上用PASV命令告诉client：“我打开了****port，你过来连接我”。

于是client向server的****port发送连接请求。建立一条数据链路来传送数据。

从上面能够看出。两种方式的命令链路连接方法是一样的，而数据链路的建立方法就全然不同。
