Today, I will talk to you about how to anonymize users in Proftpd configuration. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

ProFTPD is the most popular FTP server software after Wu-FTP. To use Proftpd, we have to learn his usual configuration.

The root directory of anonymous is/var/ftp.

anonymous The PID obtained after logging in is ftp:ftp on Linux;

When anonymous logs in to FTP, FTP software displays some welcome messages on the Client side;

Allow up to 30 anonymous logins;

Limit upload/download speeds to 100Kbytes/s and 50 Kbytes/s;

The requested URL/var/ftp/was not found on this server.

In/var/ftp/upload, you can only write, not download, and after the user enters this directory, some relevant information is displayed;

Create a basic profile:

# vi /usr/local/proftpd/etc/proftpd.conf

#Settings for hosts and physical users

ServerName "Proftp host for testing"

ServerType standalone

DefaultServer on

Port 21

User nobody

Group nobody

TimesGMT off #GMT time is Greenwich Mean Time, because local time is used, so set to off

MaxInstances 50 #Up to 50 PID of prftpd

MaxClients 100 "Sorry, we're full" #Up to 100 users allowed online

MaxClientsPerHost 5 #Up to 5 FTP connections on the same host

AllowStoreRestart on #Allow user uploads to resume! The default is off.

PassivePorts 65400 65420

Anonymous's settings

#PID permission owner for creating Anonymous under Linux

User ftp

Group ftp

UserAlias anonymous ftp

UserAlias nogoodbird ftp

#Create a message for anonymous to watch!

DisplayLogin welcome.msg

DisplayFirstChdir .message

MaxClients 30 "Anonymous logins are saturated! "

#This is important! To limit the transmission rate! The basic syntax is:

# TransferRate (STOR| RETR) Speed (Kbytes/s) user

# STOR means upload and RETR means download! Speed is Kbytes/second!

TransferRate STOR 100 user anonymous,ftp #in KBytes/second

TransferRate RETR 50 user anonymous,ftp

Denyall

#This one is only related to upload this directory and its subdirectories!

Denyall

Allowall

Create a welcome screen:

Note: If anonymous root is at/var/ftp, welcome.msg must be placed at/var/ftp/welcome.msg

# vi /var/ftp/welcome.msg

Welcome! This is a test FTP site!

My Host: %L

Current time: %T

*** Online: %M

Currently online: %N

Your host: %R

Your account number: %U

Current directory: %C

Establish special precautions:

The requested URL/var/ftp/was not found on this server.

# vi /var/ftp/upload/.message

This directory can only be uploaded, not downloaded,

Your identity is anonymous!

Create upload permissions:

# chown ftp:ftp /var/ftp/upload

# chmod 755 /var/ftp/upload

Restart!

# service proftpd restart
