Install vsftp in Ubuntu

1. Check whether the system has FTP service

PS-E | grep vsftpd

 

2. Mount vsftpd

Apt-Get install vsftpd

 

After the installation is complete, vsftpd is automatically enabled and an FTP user is created for the system.

 

3. Restart

/Etc/init. d/VsftpdRestart

 

4. default directory

By default, vsftp automatically enables anonymous accounts. You can view the directory columns corresponding to the FTP account in the/etc/passwd directory by default.

For example, here is

FTP: X: 114: 121: ftp daemon,:/srv/ftp:/bin/false
The default directory is/srv/FTP.

 

5. Configure vsftp

A. whether to allow anonymity (yes by default)

Anonymous_enable = Yes

B. whether to allow a local account to log on. (if it is commented out by default, it is not allowed)

# Local_enable = Yes

C. If a local user is enabled, set the FTP directory of the local user to its root directory.

# Chroot_local_user = Yes

D. If you want to reset an FTP directory for some local users (the file vsftpd. chroot_list has not been carefully studied)

# Chroot_local_user = Yes
# Chroot_list_enable = Yes
# (Default follows)
# Chroot_list_file =/etc/vsftpd. chroot_list

 

6. Add a user. If the local account is not enabled, add the user.

Add User net. Specify the user directory as/var/www/net, and the user cannot log on to the system.
# Mkdir/var/www/Net
# Useradd-S/sbin/nologin-D/var/www/Net
Note that-S/sbin/nologin makes it unable to log on to the system.-D specifies the user directory as/var/www/net.
# Passwd net
# Chown-r net: net/var/www/Net

Note: Set all and groups of User Directories and Their subdirectories to net.

 

7. Modify the listening port

/Etc/vsftpd. conf add listen_port = xxx

 

8. Modify the data port

Pasv_min_port = 50000
Pasvanderbilt max_port = 55000
Save and exit.
The meaning of these two statements tells vsftpd that the port range for data transmission is between 50000 and 55000.

 

 

OK.
