I guess you mean the accepted host key of the server, do you? It is kept in Windows registry, under HKEY_CURRENT_USER.

Re: Executing WinSCP3.com using SQL server 2005

OK I've solved it now. I think this is what happened:

1)Logged onto the server with administrator privilege
2)Ran the WinSCP and said Yes to the message "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."
3)Then the VB6.exe was executed under a different user and the private key file was not found, and hence the message again.
4)So I changed the SQLServerAgent service to run as the admin account I used in 1)...and it has now worked.

Just a final question - where is the private key stored to be reused for later sessions? is it a WinSCP cache or a machine cache?

I remember seeing this message when I first logged on using the WinSCP UI. Do I need to add the key file to another cache? or does something else have to be done?

Executing WinSCP3.com using SQL server 2005

Hi,
I would like to execute WinSCP3.com using a job in MS SQL Server 2005. The goal is to copy files from a different server to the server hosting the SQL server.

The details are:
WinSCP3.com - ver 1.4.0.67 from download of package ver 3.8.2.330
Server:Win2003
DB: Job configured in SQL server agent to execute a VB6.exe
vb6.exe: creates a script file depending on certain parameters. It then does ShellExecute using WinSCP3.com /privatekey=keyfile /script=newscriptfile

Problem: The script file appears to be executed but no files are transferred from the destination server.

Debug info:
No errors are reported in the SQL server job history.
I have a log file for the vb6.exe and this captures the command line call for WinSCP3.com and the shell response. The response is 42 (so not an error) and to check the command line call I opened a command prompt on the server and copied across the text from the log file *exactly*. This completes successfully and the appropriate files are copied across from the other server.

Question:
Is it a SQL server job configuration issue or is it a WinSCP3 issue. I think the former as when executed at the cmd prompt all is well. Any help would be gratefully received.
Thanks
David
