24 .SH NAME
25 CURLOPT_SSH_KNOWNHOSTS \- file name holding the SSH known hosts
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_KNOWNHOSTS, char *fname);
30 .SH DESCRIPTION
31 Pass a pointer to a zero terminated string holding the file name of the
32 known_host file to use. The known_hosts file should use the OpenSSH file
33 format as supported by libssh2. If this file is specified, libcurl will only
34 accept connections with hosts that are known and present in that file, with a
35 matching public key. Use \fICURLOPT_SSH_KEYFUNCTION(3)\fP to alter the default
36 behavior on host and key (mis)matching.
37
38 The application does not have to keep the string around after setting this
39 option.
