To verify that the sftp server is actually running, responsive and that
all curl's tests generated configuration and key files are fine, a real connection is established to the test harness sftp server authenticating and running a simple sftp remote pwd command. The verification is done using OpenSSH's or SunSSH's sftp client tool with a configuration file with the same options as the test harness socks server with the exception that dynamic forwarding is not used for sftp.
