Hi, is it possible to run both Telnet and a webserver on a µIP stack?

In theory all you have to do is create somthing like this

#define UIP\_APPCALL switch\_function

switch\_function(void)  
{  
&nbsp;&nbsp; if(port == 80)  
&nbsp;&nbsp; {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; http\_app();  
&nbsp;&nbsp; }

&nbsp;&nbsp; if(port == 23)  
&nbsp;&nbsp; {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; telnetd();  
&nbsp;&nbsp; }  
}

Is there anyway to evaluate which port on the current connection?, and is it truely enough?

Thank you

/Johnny

Sorry, my bad…i missed it in the manual.

it can be done by evaluating HTONS(uip\_conn-\>lport)
