VSFTPD Virtual Users creation BASH Script How To

The BASH scripts presented here are for the VSFTPD server that has been setup using the how to article here http://sudhakarbellamkonda.blogspot.com/2011/11/vsftpd-virtual-users-and-shell-users.html

Do these changes before using the scripts assuming that you have root access.

Create the following vuser subfolder in /etc/vsftpd/ if not done already

#cd /etc/vsftpd
#mkdir vuser


Download the scripts bundle and untar then in /etc/vsftpd/vuser folder

Latest versions and info maintained at vsftpd-virtualuser-bash-scripts 

The scripts:
vuserchk - checks the necessary files and folders necessary for these scripts
vuser.conf - the file containing configuration parameters for these scripts
vuseradd - adds a virtual user
vuserdel - delets a virtual user
vuserres - restores a deleted user
vuserpas - changes a virtual user password
vusersho - displays the user password

The scripts are very verbose and will display messages and errors which are self explanatory.


What the scripts not do:
Deleting a user will remove the user from the active list and the ftp home folder is renamed to $USER-deleted and the deleted user details are copied to a user deleted list. A script to archive and move the tarball to an archive folder is on the back burner.

Panic not be Cautious: Use the scripts wisely and carefully. Please backup before any use at production servers. The scripts have been tested and used without any errors or problems.

Six are the scripts: These scripts are very non intrusive and have a simple logic flow. Prerequisites are BASH, GAWK, SED for the scripts to work. I am hoping to introduce more functionality into the scripts and add a local user ftp home sync'er and a deleted folder archiver, once finished will add them here.

Test them, deploy for ease of mind and relax and let the scripts do the work :).

  1. In file vuserchk, you need to check if previosly exists file /etc/vsftpd/vuser/vuser_del before count lines in that file.

    if [ -e $VUSER_DEL ]
    DTOTREC=`wc -l $CONFIG_ROOT/$VUSER_DEL | cut -c 1-2`
    else
    DTOTREC="No file"
    fi
    echo "Total records in $CONFIG_ROOT/$VUSER_DEL is $DTOTREC"

  2. There is a problem in multiple places in the scripts if you happen to have similar account names, for example "customer" and "customer1".

    Workaround:
    grep $VUSER $CONFIG_ROOT/$VUSER_LIST
    should be replaced by
    grep -w $VUSER $CONFIG_ROOT/$VUSER_LIST

    Similarly,
    awk '/'$VUSER'/ {...
    should be replaced by
    awk '/\<'$VUSER'\>/ {...

    These changes will make sure you'll not select "customer1" when trying to modify/work with "customer".

    Thanks for the script by the way!
