Answer 1

Hi adiyakiran,
This is possible in third party ftp server wu-ftpd. you can download it from http://www.sunfreeware.com.
read wu-ftpd faq URL: http://www.wu-ftpd.org/wu-ftpd-faq.html
Testing on a different port number then ftp:21
This can be done from the command line or with a special definition in /etc/services ,/etc/inetd.conf. For command-line, look up -P and -p in the ftpaccess(5) manpage.
To set up with special definitions, add 2 ports with consecutive numbers in /etc/services, and then start wu-ftpd on these ports. Add to /etc/services something like :
ftptest 4021/tcp #command port
ftptest-data 4020/tcp #data port
Then start wu-ftpd from /etc/inetd.conf like :
ftptest stream tcp nowait root /usr/etc/in.ftpd in.ftpd
The key is the name 'ftptest' which associates the port assignment in the /etc/services file to that in the inetd.conf file. Make certain the choice of ports in /etc/services (4021 and 4020 above) are from the local use list and don't conflict with other port assignments (see RFC1700, ASSIGNED NUMBERS). One important subtlety. The data
port is not really derived from the data port declaration in the /etc/services file. The FTP specification (RFC765) states the data port is defined as one less than the command port. However, including the data port declaration in the /etc/services file prevents it from being accidentally assigned to something else.
Thanks.
