I am trying to ssh to amazon ec2 instance from shell using the following command

ssh -vi sec.ppk [email protected]

but failed to connect

Here is the debug output generated by the above command

OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009

Enter passphrase for key 'sec.ppk': 

Why it is asking passphrase for sec.ppk

What is the issue? Can anyone help?

Forgot to mention that I successfully made a connection using FileZilla with same above credentials

This might work:

ssh -i /directory/yourkeypair.pem [email protected]
