Host Key Not Configured

2023-01-09 23:41

I am trying to create a scheduled task to upload and delete some files. I am getting a host key error when calling my script from a batch file. However if I open WinSCP.com and paste each line in individually, they all work flawlessly. I added the -hostkey=* to my open command and it still says there is a host key error.
Batch File

"C:\WinSCP\winscp.com" /script=filename.txt /log=brwinscp.log /ini=nul

Script

open sftp://brftp:workingpassword@serverIP:2222 -hostkey=*
put -delete c:\FTP\brftp\FileNameID_* /
exit

Please attach a complete log.

Though you should not be using -hostkey=*. See
Where do I get SSH host key fingerprint to authorize the server?

In your script try changing -hostkey like so:

open sftp://brftp:workingpassword@serverIP:2222 -hostkey="ecdsa-sha2-nistp256 256 KQU3bUJpxEZzhK9JunBzk/2P8fLL6RLlRkBBzrLyqzY"

YMMV

@gorphus22: Your script does not contain any -hostkey switch:

open sftp://cs_br:***@serverIP:2222

Make sure you are editing the right file. Note that the working directory of your script is C:\WinSCP\Scripts. So the /script=script.txt refers to the C:\WinSCP\Scripts\script.txt.
