Set \fICURLSSH_AUTH_ANY\fP to let libcurl pick a suitable one. Currently CURLSSH_AUTH_HOST has no effect. If CURLSSH_AUTH_AGENT is used, libcurl attempts to connect to ssh\-agent or pageant and let the agent attempt the authentication. .SH DEFAULT CURLSSH_AUTH_ANY (all available) .SH PROTOCOLS This functionality affects scp and sftp .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file"); curl_easy_setopt(curl, CURLOPT_SSH_AUTH_TYPES, CURLSSH_AUTH_PUBLICKEY | CURLSSH_AUTH_KEYBOARD); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } } .fi .SH AVAILABILITY Added in curl 7.16.1 .SH RETURN VALUE \fIcurl_easy_setopt(3)\fP returns a CURLcode indicating success or error.
