Hi Guys

 

I can't see any basic or digest authentication in the RTCS HTTP server. Have I missed something obvious, or have these features been taken out and are something I need to approach Embedded Access for?

I need to put in some kind of fairly simple password-based security... just wondering what everyone thought the best course of action would be.

 

Cheers!

 

Joe

I solved this issue by follow steps:

 

1. In file ../Freescale MQX 3.5/rtcs/source/httpd/httpd.c

  go to function

 

static void httpd_processreq(HTTPD_STRUCT *server, HTTPD_SESSION_STRUCT *session)

find a line

 

 

int cgi = 0, res = 0, auth = 0;    // authorization required flag

 

and change it to

 

int cgi = 0, res = 0, auth = 1;    // authorization required flag

 

In same file find a function

 

void httpd_ses_init(HTTPD_STRUCT *server, HTTPD_SESSION_STRUCT *session, const int sock)

and insert line

 

 

HTTPD_MEMZERO(session->request.auth, server->params->max_auth);

 

before

 

#if HTTPDCFG_POLL_MODE        session->line_used = 0;#endif

 

2. Add to my project authentification callback function like this:

 

int _http_auth_internal (HTTPD_SESSION_STRUCT* session){  // check user login  if (strncmp(session->request.auth, your_login, YOUR_LOGIN_SIZE) != 0)    return 1;  // check user password  if (strncmp(session->request.authPasswd, your_pass, YOUR_PASSWORD_SIZE) != 0)    return 1;  // all good  return 0;}

 

And attach this callback with

 

 

HTTPD_SET_PARAM_AUTH_FN(server, _http_auth_internal);

 

 

That's all. Work fine in my project on MQX version 3.5.

And of course recompile RTCS after changes from my previous post.

Hello!!!

It is my first work on Freescale platform!! I have tried your suggest and it works fine!!!! But... I want something different... :smileyconfused: Is it possible to have the authorization form (pop-up with user and password) showed only when the user goes in a particular page html?

Have you got any idea for implement this feature?

Thank you very much!!!!

Solved! It was easier  than I thought...
I examine the request and, if it is the protected page, active authorization flag.


  if(strcmp(" request ",session->request.path) == 0)

    {

                auth=1;

    }


:smileywink:

Hello,

I am new on MQX and RTCS and I would like to use the Authentification code, but i don't understand or and how integrate him into my code !

I change and recompile RTCS as JonSmith describes it, but I am stopped by:


2. Add to my project authentification callback function like this:

 

int _http_auth_internal (HTTPD_SESSION_STRUCT* session){  // check user login  if (strncmp(session->request.auth, your_login, YOUR_LOGIN_SIZE) != 0)    return 1;  // check user password  if (strncmp(session->request.authPasswd, your_pass, YOUR_PASSWORD_SIZE) != 0)    return 1;  // all good  return 0;}

 

And attach this callback with

 

 

HTTPD_SET_PARAM_AUTH_FN(server, _http_auth_internal);

 

Have you an example or more information ?

 

Beforehand thank you !

 

PS sorry for my very bad English

Hi JonSmith

 

That's brilliant, thanks! I think that's just saved me a day's coding. 

 

Virtual bottle of wine coming through now...
