sftp issue

Hi experts,

While trying to sftp from one the red hat linux box it is giving following error.

Status:                      Connecting to 10.1.82.155...
Response:               fzSftp started
Command:               open "prodbill@10.1.82.155" 22
Command:               Pass: *********
Error:                        Authentication failed.
Error:                        Critical error
Error:      Could not connect to server

Request your help to resolve the issue. Are there any config files that needs to be changed for the same?

Can you provide some more details?

Are you trying to sftp to or from the Red Hat box? What is at the other end of the connection, i.e. what are you trying to transfer to/from?

/etc/ssh/sshd_config manages the sftp server and /etc/ssh/ssh_config manages the sftp client.
