How to connect to PSFTP using different username

Question

I'm trying to log into PSFTP (Putty SFTP) and I'm able to login only using default username 'centos'. How do I login with different username?


C:\SMS\Putty>psftp sample (sample is the saved session in my putty which contains hostname and private key)
login as: centos
Remote working directory is /home/centos
psftp>

Connection is successful.

Now with different username(other than default i.e., centos) I'm getting below error.

C:\SMS\Putty>psftp sample
(sample is the saved session in my putty which contains hostname and private key)

Error:

Using username "ashuthi".
Server refused our key
Fatal: Disconnected: No supported authentication methods available (server sent: publickey,gssapi-keyex,gssapi-with-mic)

Answer 1

Presumably the two users have different private keys - are you sure ashuthi's private key is being used (and is correct)?
