hostkey parameter includes double quotes

2018-05-09 18:00

Hello,

I'm writing a script to connect server. Problem is that if I using double quotes, they are being included into the key. You can see it from the log:

"(Exception) **Host key does not match configured key "ssh-ed25519 256 xx:xx:xx..."!**".

If I put single quotes script simply doesn't run (just blinks cmd, but log being empty after this).

This is my script:

open sftp://root@XX.XXX.XXX.XX -privatekey=id_rsa.ppk -hostkey="ssh-ed25519 256 xx:xx:xx..."
put "license.txt" /root/license.txt
exit

And I'm calling script like this:

.\WinSCP.exe /console /script="prod_to_server.txt" /ini=nul /log="scriptLog.log"

How to omit quotes in the hostkey?
Thank you in advance!

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, use /log=path_to_log_file command-line argument. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Sorry, but that log is useless. Your have removed the all hostkey fingerprints. Those are fingerprints of a public key. It's not sensitive/secret at all.
