NAME

       CURLOPT_SSH_KNOWNHOSTS - file name holding the SSH known hosts

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_KNOWNHOSTS, char *fname);

DESCRIPTION

       Pass a pointer to a null-terminated string holding the file name 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 will only accept 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

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
         curl_easy_setopt(curl, CURLOPT_SSH_KNOWNHOSTS,
                          "/home/clarkkent/.ssh/known_hosts");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY

       Added in 7.19.6

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.
