Can i do TELNET and FTP to the remote machine with automatic login and password through shell script ? if yes,how?? Thanks

ftp can be scripted pretty easily if you want only limited funtionality. Telnet as a chatty protocol is not so easy with a normal shell. Look at expect. This and more can be done easily with expect.

Typically to script ftp you create a .netrc file in your home directory, owned by you, not visible to others, containing e.g: machine somehost login someuser password somepassword Then "ftp somehost" automatically logs you in using user/password. You could use this with a "here document" e.g: ftp somehost <<-ENDFTP ls bye ENDFTP
