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