| .TH CURLOPT_SSH_KNOWNHOSTS 3 "May 31, 2017" "libcurl 7.57.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_SSH_KNOWNHOSTS \- file name holding the SSH known hosts |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_KNOWNHOSTS, char *fname); |
| .SH DESCRIPTION |
| Pass a pointer to a zero 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 \fICURLOPT_SSH_KEYFUNCTION(3)\fP 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. |
| .SH DEFAULT |
| NULL |
| .SH PROTOCOLS |
| SFTP and SCP |

| "/home/clarkkent/.ssh/known_hosts"); |
