I suspect that my issue has to do with properly formatting the strings to libcurl, and for Windows in particular.
1. I want to set the remote port for SFTP, so I believe that I should *NOT* user CURLOPT_CONNECT_TO, but use CURLOPT_RESOLVE, correct? 2. The SSH/SFTP connection lies on an internal network, with no DNS or domain names. In the CURLOPT_RESOLVE description, the curl_slist string has the format HOST:PORT:ADDRESS Should I leave the HOST empty or repeat the address? Which of the following formats do I use, ":22:10.20.30.40" or "10.20.30.40:22:10.20.30.40"? 3. When setting up the CURLOPT_URL, I need to connect to the server to a user account on the D: drive. I tried using the following call, but I'm afraid that it might be malformed. Again, this is for SFTP between two Windows 10 machines. result = curl_easy_setopt( curlSessionHandle, CURLOPT_URL, "sftp://[email protected]/~/Users/wi-19981-rda/Device_A/some_file"; ); I tried converting the slashes to the Windows format "sftp:\\[email protected]\\~\\Users\\wi-19981-rda\\Device_A\\some_file" but then libcurl signals a protocol error. I'm already specifying the protocol in another option call, so is it necessary to specify the protocol in the CURLOPT_URL call as well? 4. Does the D: drive need to be explicitly listed in the path, or is it enough to use the /~/? ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
