CURLOPT_SSH_KNOWNHOSTS(3) Library Functions Manual CURLOPT_SSH_KNOWNHOSTS(3)
NAME
CURLOPT_SSH_KNOWNHOSTS - filename 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 filename 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
only accepts 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
This functionality affects scp and sftp
EXAMPLE
int main(void)
{

curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
curl_easy_setopt(curl, CURLOPT_SSH_KNOWNHOSTS,
"/home/clarkkent/.ssh/known_hosts");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
