error in ftp while uplodaing/downloading

Question

This year, in my engineering class, we are learning OS and Doing Shell Programming. I keep a backup of my work on FTP which used to work fine, but now I am getting this error, while uploading and download to the server:

ftp> dir
500 I won't open a connection to 10.23.28.243 (only to 1.23.149.28)
ftp: bind: Address already in use

&

ftp> put asdf.sh
local: asdf.sh remote: asdf.sh
500 I won't open a connection to 10.23.28.243 (only to 1.23.149.28)

I don't have college server access, please help me with this problem.

Is the server listening on port 21? Do you have a firewall running? — Mitch, Aug 11 '13 at 12:20
yes for web access protection they have college level firewall — Rohit Karadkar, Aug 11 '13 at 12:37
You need to allow access to port 21 in the firewall. Try ftp -p what happens? — Mitch, Aug 11 '13 at 12:40

Make sure that the server is listening on port 21, and that the port is allowed in the firewall rules.

You could also try using passive mode by doing ftp -p
