CURLOPT_SSH_KNOWNHOSTS(3) curl_easy_setopt options CURLOPT_SSH_KNOWNHOSTS(3) 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 (mis)matching. 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.
