NAME

6       CURLOPT_SSH_KNOWNHOSTS - file name holding the SSH known hosts
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_KNOWNHOSTS, char *fname);
12

DESCRIPTION

14       Pass a pointer to a null-terminated string holding the file name of the
15       known_host file to use.  The known_hosts file should  use  the  OpenSSH
16       file format as supported by libssh2. If this file is specified, libcurl
17       will only accept connections with hosts that are known and  present  in
18       that  file,  with a matching public key. Use CURLOPT_SSH_KEYFUNCTION(3)
19       to alter the default behavior on host and key matches and mismatches.
20
21       The application does not have to keep the string around  after  setting
22       this option.
