Which protocol? SSH, FTP, (HTTP)?

EDIT: please don't post your password!

[Lars Noodén]

Yes, which protocol? If it is HTTP or anonymous FTP, then use lynx or wget. If it is SSH then use sftp or scp.

it's ssh how can use sftp of scp??

[Lars Noodén]

Check the manual page for sftp for details, but the general usage is with the username and remote host:

[s]sftp -l user server.example.org/s]
sftp user@server.example.org

Inside sftp, put and get are your two main commands, but there are many others described in the manual page.

What i have to do is download a certain file from the server and move it to my home folder..

What i have to do is download a certain file from the server and move it to my home folder..

It sounds like scp would be better for this than sftp.

scp mohan@10.40.70.68:/path/to/remote/file  ~/

To use sftp, you could set up a batch file with cd and get commands, then do:

sftp -b name_of_batch_file mohan@10.40.70.68

[Lars Noodén]

Oops. I wrote the wrong line. -l does not work for sftp so it would work like this instead:

sftp mohan@server.example.org

sftp mohan@server.example.org

I tried like this in a normal terminal

sftp mohan@10.40.70.68:/home/mohan/link

then it prompt me for the password?? can't i get the file without prompting for the password of mohan at the server?

[Lars Noodén]

To get a file without the password, you'll have to set up a web server or an Anonymous FTP server and then put the file in the directory that is published by the server. Apache is by far the most common web server, but nginx is gaining in popularity.
