How to add users for FTP server

•  Login as root 
  

  • Create a script addftpspecial :- 

     #!/bin/ksh

    
    
    

    
    if [ "$1" = "" -o "$2" = "" ]
    then
            echo Usage: $0 username subdir
            exit
    fi
    
    useradd -d /FTPSites/WarehouseOptimizationFTP/$2 -g WOFTP -M -s /usr/sbin/nologin $1

    
    

    
    
• Run the script addftpspecial with the userename and the home directory for the user. The script is in the root home directory on ftp server.

# ./addftpspecial username ftpsubdirectory

Note:- for root of the ftp directory use this

# ./addftpspecial ftpwonewuser ./ (this will place the user in the /FTPSites/WarehouseOptimizationFTP/ directory)

Note:- The addftpspecial script add's primary group as WOFTP for the new user, so if you want the user to have access only to his directory then do the following commands

# groupadd username (this will create a group with the same name as the userename)

# usermod -g username username (this command will put the new group as the primary group)

• Use the passwd command to assign a password to the user

# passwd username

• Go to the directory /etc

# cd /etc

• Edit the file vsftp.chroot_list.

# vi vsftp.chroot_list (add username to list of users - this file causes the user to be locked into their home directory)

# grep username passwd (show username from password file - copy directory name from information)

# mkdir directory-copied-from-passwd

# chown username:WOFTP directory-copied-from-passwd (adding the WOFTP group will give the group permission to everyone who is in the WOFTP group for the new user directory)

# chmod 775 directory-copied-from-passwd (This will give full permission to the group WOFTP)
