I am trying to securely transfer a file between two windows 10 devices, and I get error 67, "CURLE_LOGIN_DENIED" when calling curl_easy_perform(). All of the curl_easy_setopt() calls return success.
The server has been configured as an SSH server using OpenSSH for Windows 10 and using OpenSSH commands from a Windows command prompt are successful in transferring files. The code below is below with changes to the user name, password, IP addresses, directories and file names. I tried the code below commenting out the user password, since we are trying to use keys for authentication. 1. The Server has been configured to use the D: drive. Is it enough that I have /~/ after the user@IPaddress? mailto:user@IPaddress 2. What kind of debugging would aid in resolving this issue? void sftp_send() { CURL *pCurlSessionHandle = NULL; CURLcode eResult = CURLE_OK; struct curl_slist *psConnect_to = NULL; FILE *pFileReadHandle = NULL; pFileReadHandle = fopen( "C:\\Users\\my.name\\.ssh\\client_file_name", "r" ); if ( pFileReadHandle == NULL ) { return -1; } pCurlSessionHandle = curl_easy_init(); if ( pCurlSessionHandle != NULL ) { CString s = NULL; // For DEBUG ONLY!! psConnect_to = curl_slist_append( NULL, "189.123.1.2:22:189.76.11.54:22" ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_RESOLVE, psConnect_to ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_URL, "sftp://[email protected]/~/Users/remote.user_name/dest_file_name"; ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_PROTOCOLS, CURLPROTO_SFTP ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_SSH_AUTH_TYPES, CURLSSH_AUTH_PUBLICKEY ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_SSH_PUBLIC_KEYFILE, "/Users/my.name/.ssh/renamed_key.pub" ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_USERNAME, "remote.user_name" ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_USERPWD, "Secr3tP4s$word!" ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_READFUNCTION, NULL ); eResult = curl_easy_setopt( pCurlSessionHandle, CURLOPT_READDATA, (void *)pFileReadHandle ); eResult = curl_easy_perform( pCurlSessionHandle ); if ( eResult != CURLE_OK ) { s.Format("Failed to perform SFTP key file transfer! err=%d", eResult ); AfxMessageBox(s); } curl_easy_cleanup( pCurlSessionHandle ); } curl_slist_free_all( psConnect_to ); if ( pFileReadHandle != NULL ) { fclose( pFileReadHandle ); } } Best Regards, Mike Loutris (Email) [email protected] mailto:[email protected]
