Code:

error: 'class EthernetClient' has no member named 'getRemoteIP'

[Reply #16 on:]

Nice one but im still staggering around in near darkness may i see the rest of the code then? lol

[Reply #17 on:]

Have you tried this? http://arduino.cc/forum/index.php/topic,100267.msg752315.html#msg752315

[Reply #18 on:]

oops, I used Android (and you don't see scroll bars on the code) so it looked like far less code than you posted...

I'll try it out, thanks....

[Reply #19 on:]

It is only three lines to add to the code to get the remote IP and you already figured out the most important one. The rest is the explanation.

[Reply #20 on:]

OK I added the lines, but it's still going over my head..

in short the code I just uploaded returns these errors

In file included from WebServer.cpp:7:
C:\arduino\arduino-1.0\libraries\Ethernet/utility/w5100.h:234: error: 'static uint16_t W5100Class::writeRIPR(uint8_t*)' cannot be overloaded

(EthernetCode ...zip contains my modified ethernet lib including the sub folders and modifications)


Thanks for helping.....

[Reply #21 on:]

I propose to delete the additional copy of ethernet lib and add the line

Code:

__GP_REGISTER_N(RIPR,   0x000C, 4); // Remote IP address

directly to w5100.h in the Arduino library directory. It is a small change without the hassle of cloning the library. You just have to remember that you made the change when updating to a newer version of Arduino.

The rest is done in your sketch by including w5100.h and calling the new function

Code:

#include <Ethernet.h>
#include <utility/w5100.h>
...
uint8_t remoteIP[4];
...
W5100.readRIPR(remoteIP);

[Reply #22 on:]

Step 1 . Open w5100.h add the line

  __GP_REGISTER_N(RIPR,   0x000C, 4); // Remote IP address


Step 2.  

Insert code


  static uint16_t writeRIPR(uint8_t *_buff) {
    return write(0x000C, _buff, 4);
  }
  static uint16_t readRIPR(uint8_t *_buff) {
    return read(0x000C, _buff, 4);
  }
  static uint16_t writeSIPR(uint8_t *_buff) {
    return write(0x000F, _buff, 4);
  }
  static uint16_t readSIPR(uint8_t *_buff) {
    return read(0x000F, _buff, 4);
  }

/// What file?


Step 3, compile?

[Reply #23 on:]

how does coding in C/C++ not make someone drink excessively ?

[Reply #24 on:]

No, wrong. There is only one step. Only one line to add to w5100.h - do not drink and program

I edited my previous post, so read it again, please.

Just now remembering, below has the info on how to make the code work to get the client IP address. Just a little copy/paste work in the correct files.

[Reply #26 on:]

Yayyyyyyyy thank you!!!

for future reference for anyone else..

Code:

       char crrip[16];
        byte rip[4];
  
        client.getRemoteIP(rip); // where rip is defined as byte rip[] = {0,0,0,0 };     
        sprintf(crrip, "%d.%d.%d.%d", (unsigned char)rip[0], (unsigned char)rip[1], (unsigned char)rip[2], (unsigned char)rip[3]);
        client.print("Welcome ");
        client.println(crrip);

modifications to ethernet...

I added the following lines to the end of the EthernetClient.cpp file:
uint8_t *EthernetClient::getRemoteIP(uint8_t remoteIP[])
{
  W5100.readSnDIPR(_sock, remoteIP);
  return remoteIP;
}

I then added the following line (under the virtual void stop(); line)to the EthernetClient.h file:
uint8_t *getRemoteIP(uint8_t RemoteIP[]);//adds remote ip address

Finally I used the following code in my sketch to access the remote IP:
client.getRemoteIP(rip); // where rip is defined as byte rip[] = {0,0,0,0 };

to display the IP in the serial monitor, I used:

for (int bcount= 0; bcount < 4; bcount++)
     {
        Serial.print(rip[bcount], DEC);
        if (bcount<3) Serial.print(".");
     }

I'm not sure that this is the most elegant way, but it works in the IDE v1.0

Works perfectly Cheers man

There it is in action - that means I can now play with some of the other functionality  like remote port etc etc (actually one day...maybe lol)
