I am trying to sftp into an a server hosted by someone else.
To make sure this worked I did the standard sftp [email protected]
i was promted with the password and that worked fine.
I am setting up a cron script to send a file once a week so have given them our public key which they claim to have added to their authorized_keys file.
I now try sftp [email protected]
again and I am still prompted for a password, but now the password doesn't work...
Connecting to [email protected]...
[email protected]'s password:
Permission denied, please try again.
[email protected]'s password:
Permission denied, please try again.
[email protected]'s password:
Permission denied (publickey,password).
Couldn't read packet: Connection reset by peer
I did notice however that if I simply pressed enter
(no password) it logged me in fine...
So here are my questions:
- Is there a way to check what privatekey/pulbickey pair my sftp connection is using?
- Is it possible to specify what key pair to use?
- If all is setup correctly (using correct key pair and added to authorized files) why am I being asked to enter a blank password?
Thanks for your help in advance!
UPDATE
I have just run sftp -vvv [email protected]
....
debug1: Authentications that can continue: publickey,password

debug1: read PEM private key done: type RSA
debug1: Authentications that can continue: publickey,password
debug1: Trying private key: /root/.ssh/id_dsa

debug2: we did not send a packet, disable method

debug3: remaining preferred: ,password
debug3: authmethod_is_enabled password

It seems to suggest that it tries to use the public key... What am I missing?
