CURLOPT_SSH_KNOWNHOSTS3
Filename holding the ssh known hosts
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_KNOWNHOSTS, char *fname);
Overview
Pass a pointer to a null-terminated string holding the filename of the known_host file to use. The known_hosts file should use the OpenSSH file format as supported by libssh2. If this file is specified, libcurl only accepts connections with hosts that are known and present in that file, with a matching public key. Use CURLOPT_SSH_KEYFUNCTION(3) to alter the default behavior on host and key matches and mismatches.
The application does not have to keep the string around after setting this option.
Default
NULL
Protocols
SFTP and SCP
Examples
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_KNOWNHOSTS,
"/home/clarkkent/.ssh/known_hosts");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
Return value
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
