5,ConfigurationFTPService

Vim/etc/vsftpd. conf

Enable = yes --> anonymous_enable = No // anonymous users are not allowed to access the service. By default

Xferlog_file =/var/log/vsftpd. log # sets the path for saving service logs of vsftpd. Note: This file does not exist by default. Must be manually touch

# Idle_session_timeout = 600 --> idle_session_timeout = 600 // The session times out. The client connects to the FTP but is not operated. It is commented out by default and can be modified as needed.

# Async_abor_enable = yes --> async_abor_enable = Yes // support for asynchronous transmission. It is commented out by default. Remove the comment.

# Ascii_upload_enable = yes --> ascii_upload_enable = Yes // supports the download feature in ASCII mode. By default, it is commented out. Remove the annotation.

# Ascii_download_enable = yes --> ascii_download_enable = Yes // supports the upload function in ASCII mode. By default, this function is commented out.

# Ftpd_banner = welcome to blah FTP service // The FTP logon welcome message, which is commented out and can be omitted

# Chroot_local_user = yes --> chroot_local_user = Yes

// Disable local users from logging out of their FTP home directory. The local user is commented out and the comment is removed.

 

6,Configure iptables Firewall

Service ipstables status

The above steps cannot be run. Run the following command to check the port number allowed by the firewall. We know that the FTP port number is "20, 21". The result shows that there is no port number.

 

In this case, you need to configure "/etc/sysconfig/iptables:

Vim/etc/sysconfig/iptables

 

First list the files with "iptables" fuzzy match, and then add the following content to the "iptables" file after the above name.

-A input-M state -- state new-m tcp-p tcp -- dport 21-J accept

-A input-M state -- state new-m tcp-p tcp -- dport 20-J accept
