SFTP with .PPK file

Hi Steve,

The tsNet command only requires the SSH private key, so that is ok.

I will test again here to make sure there is nothing else going on in LC 
9.0 DP6....

Just to check though, I assume your private key does not require a 
passphrase?

Another thing to try is to download the following simple stack:

https://downloads.techstrategies.com.au/tsnet/debug_liburl.livecode

Run that stack at the same time as your own, and click "Start Debug" 
before you try make the SSH connection.

It should provide some additional debug information that may shed more 
light on what is actually happening.

Regards,

Charles
