[lwip-users] TFTP client on lwip , timeout problem

[Durgaprasad Chivukula]

Hi Frnds ,

 

  I got rid of the problem which I mentioned earlier about the ip_route function in ip.c , changed a bit of my tftp implementation. I am now facing with a peculiar problem . When I try to "get'/put" a file  from/to  a remote host  , I receive a debug message tapif_input :ARP packet  and after some time its timing out and exits.I tried to capture the output from ethreal on tap 0 interface , the tftp  RRQ/WRQ (for get &put) is sent and also the ARP reply is sent , I am seeing a partial UDP output on ethereal .Ofcourse the timeout is implemented as apart of tftp , even if I increase the

value of timeout , the result is the same , I do not see any other debug messages other than tapif_input :ARP packet , even if I trun on all the debug messages . I tried to debug the program using DDD ( Data Display Debugger of Linux , I use Linux 2.4.20-8 , lwip 1.1.0 on tap0 interface)

I received a segmentation fault in netconn_recv module of api_lib.c  , I use socket interface of lwip and trying to sort out the problem , Please give me some pointers about my problem , what might have went wrong. ??

 

 

 I saw messages on lwip , regarding tftp client on lwip ... if you guys faced this type of problem please let me know .If you already have a tftp client on lwip running please share me the ideas, so that it would be helpful for me ..Please reply me ...

 

If you want more information , I can send the outline of my tftp implementation using socket interface..Help!!!!!!!!!!

 

Thanks
