script did not read the private key file

Hi Martin,

I have tried a script and passed the private key in /privatekey.

winscp3.exe /console scp://xxx@ftp.xxx.org:xx /privatekey=privatekey.ppk /script=myscript.txt /log=myscript.log

The script works perfectly through the scheduled task on my own computer. However, when we tried to run the script on our cluster ftp server, the script runs but it does not read the private key file. Below is the log message that did not read the key file. Could you please help to figure why the difference?

Thank you in advance!!!

It does not get that far to read the private key. Please read documentation.

This is the difference I found on the key reading --
1. One my own computer, the log message is like this --
. Host key fingerprint is:
. ssh-rsa xxxx xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
. Initialised AES-128 client->server encryption
. Initialised HMAC-SHA1 client->server MAC algorithm
. Initialised AES-128 server->client encryption
. Initialised HMAC-SHA1 server->client MAC algorithm
! Using username "xxxxxx".
. Reading private key file "privatekey.ppk"
. Offered public key
. Offer of public key accepted
! Authenticating with public key "dsa-key-20060523".
. Access granted
. Opened channel for session
. Started a shell/command

2. On the cluster server, the log message is like this --
. Using Diffie-Hellman with standard group "group1"
. Doing Diffie-Hellman key exchange
. Asking user:
. The server's host key was not found in the cache. You have no guarantee that the server is the computer you think it is.
. The server's rsa2 key fingerprint is:
ssh-rsa xxxx xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
. If you trust this host, press Yes. To connect without adding host key to the cache, press No. To abandon the connection press Cancel.
Continue connecting and add host key to the cache? ()
---END of Log---

ALSO: The script ran succseefully by manually double click the batch file. But it failed and did not read key file if ran the batch file from a Windows Scheduled Task.

Any idea? :? Thanks!

Have you read the documentation? Or at least the FAQ?

Thanks and yes the FAQ is very helpful :D
We copied the ini file over to the server and the problem is resolved!

Thanks again for helping!
