Need help trying to figure out this DataSource I found online.

Hi mnagel. I set the host properties on the collector, and when I test the script, I return the following: com.jcraft.jsch.JSchException: java.net.UnknownHostException: sftp://********  

That sftp site is what I'm using for the sftp.site host property. That's the host I always use to connect to my sftp site, but it looks like it's not working. For science, I checked to make sure that I could connect to the sftp site directly from my collector host, and I successfully able to.
