havn't got an xinetd file for vsftpd, so i am guesing it is running as standalone and controlled from xinetd, or did you mean to controll the overall connections from xinetd.conf by changing the defualt from 60 to something else?
instances             = 10 for example
exellent looking resource, linuxplanet..

it is upto u, if u want controll all the connection change the values in default or u have to put this line into service ftp to controll ftp connection.
instances             = 10

Let's use the vsftpd xinetd configuration file:

# default: off
# description: The vsftpd FTP server serves FTP connections. It uses \
#       normal, unencrypted usernames and passwords for authentication.
service ftp
{
        disable         = no
        socket_type             = stream
        wait                    = no
        user                    = root
        server          = /usr/sbin/vsftpd
        nice                    = 10
}

Notice that this file, like all of its cousins in /etc/xinetd.conf, starts with a line in the form service <servicename>. <servicename> is one of the items in /etc/services or one of the other files listed in this tutorial, and refers to the basic functionality provided by this particular tool. In the case of vsftpd, it's not hard to guess that the service is ftp.

Inside the braces are the options for this specific service. Here I'm only going to define what these particular settings mean. We'll get into the specifics of these options in the tutorial. The vsftpd setup is, from top to bottom:

    * The port is open and the service is available.
    * FTP uses TCP so that it can ensure that all of the data has arrived, and so is a streaming socket type.
    * Streaming sockets are typically set to no wait.
    * This FTP server runs as root.
    * This FTP server is located at /usr/bin/vsftpd.
    * This command runs at an average priority level.

All of these settings are in addition to what was set in xinetd.conf.

sorry, but i didn't feel that helped me, being  a bit new to all this linux stuff, just copied and pasted other website, i am still at a loss as to why there is no vsftpd file in the xinetd.d directory. So I decided to do my homework first and learn all about xinetd (i think my installation of it is not right)
Soooo this was my first go on this "forum" and not sure how it all works, didn't mean to offend .After (re) reading the "how do i know what grade to give" h
thing I should of given you the chance to sort out the area of my misunderstanding with xinetd, apologies..
