Using dhcpctl_new_authenticator throws 'connection reset by peer' at dhcpctl_wait_for_completion

[Johnson koil Raj]

Hi,

     I am trying to use the authentication process  available in DHCP 
api. If I tried to use the dhcpctl_new_authenticator it always fails. If 
I doesn't use that every thing works fine.

Here are my observations.

1) If I use this code.

   dhcpctl_handle authenticator = NULL;
   const char *keyname = "omapi_key";
   const char *algorithm = "HMAC-MD5";
   const char *secret = 
"khN6caXkA8D6AjvbzFjFq43SPiI6f/UflutVKC9cxY2kpZGwDQG0dWxLGZ9pavPoGydbqYMKospa/0uVyjnTNw==";

  status = dhcpctl_new_authenticator (&authenticator,
                                       keyname,
                                       algorithm,
                                       secret, strlen(secret) + 1);

The  dhcpctl_wait_for_completion call returns status 'connection reset 
by peer'.

In dhcpd.conf  the following configuration is used.

# Key for OMAPI
omapi-port 9991;
key omapi_key {
   algorithm HMAC-MD5;
   secret 
"khN6caXkA8D6AjvbzFjFq43SPiI6f/UflutVKC9cxY2kpZGwDQG0dWxLGZ9pavPoGydbqYMKospa/0uVyjnTNw==";
};
omapi-key omapi_key;


2) If I use this sort of code

      status = dhcpctl_connect (&connection, "127.0.0.1", 9991, 0);

In dhcpd.conf  I commented out omapi-key entry.

# Key for OMAPI
omapi-port 9991;
key omapi_key {
   algorithm HMAC-MD5;
   secret 
"khN6caXkA8D6AjvbzFjFq43SPiI6f/UflutVKC9cxY2kpZGwDQG0dWxLGZ9pavPoGydbqYMKospa/0uVyjnTNw==";
};
#omapi-key omapi_key;

Now everything work fines.


Whether I am missing any stuff when using keys for authentications. Any 
help would be greatfull.

Thanks,
Johnson
