I am trying to sftp into an a server hosted by someone else.
To make sure this worked I did the standard
sftp email@example.com 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 firstname.lastname@example.org again and I am still prompted for a password, but now the password doesn't work...
Connecting to email@example.com... firstname.lastname@example.org's password: Permission denied, please try again. email@example.com's password: Permission denied, please try again. firstname.lastname@example.org'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!
I have just run
sftp -vvv email@example.com

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