In vsftp server we can use fixed commands. Is it possible to use few commands like vi, wget etc. after logging in to a ftp server? Is it possible if we make changes or any thing like that. As per my my knowledge we can't but i have a feel nothing is impossible. when we use help command in it it shows some commands there and we can use only those commands. Similarly can't we inject some more commands in to it?
ftp> vi file
some thing like the above............!!!!
