thanks for the reply , I tried the solution ,but even though there are no users connected to the ftp server it gives a value 2 and on the http server it gives a value 1.
and also i wrote the program using the given solution , i used the system("ps -ef|grep -c ftp > somefile") inside my program ,when i saw the output in the filet it had a value 3 , when no users were connected and if i used the same command on the prompt i get the value 2 how is this possible, please help me

And in the case of HTTP server there is no change like the above if no users are connected it gives the value 1

ftpusers

FTPUSERS(5)						     Linux Programmer's Manual						       FTPUSERS(5)

NAME

       ftpusers - list of users that may not log in via the FTP daemon

DESCRIPTION

       The  text  file	ftpusers  contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon.  This file is
       used not merely for system administration purposes but for improving security within a TCP/IP networked	environment.   It  will  typically
       contain	a  list  of  the  users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP
       server daemon.  Such users usually include root, daemon, bin, uucp, and news.  If your FTP server daemon doesn't use ftpusers  then  it	is
       suggested  that	you  read  its	documentation  to find out how to block access for certain users.  Washington University FTP server Daemon
       (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers.

   Format
       The format of ftpusers is very simple.  There is one account name (or username) per line.  Lines starting with a # are ignored.

FILES

       /etc/ftpusers

SEE ALSO

       passwd(5), proftpd(8), wuftpd(8)
