Re: "Keep-Alive" function will not work

I belive that you need to set the pcb option:  SOF_KEEPALIVE

Take a look at this link, worked for me:

write into connection directy

Hi Folks,

I'm working on a microcontroller application with FreeRTOS + LwIP 1.4.1.
The situation: I'm reading data from the SD card via SPI and send it over TCP connection (with netconn API). Currently it's done by:
copy data into buffer
put buffer into netconn_write()

The question is:
How can I get the buffer of the connection and write directly into it?

Regards,
Norbert

lwip ARP reply delay at first time

Hi all.

I have a problem with lwip ARP reply.
My board is connected to the notebook directly. After board power is on 
I am trying to ping (my board) it, I can view ARP requests in Wireshark, 
but not ARP replies. After the 5-th request the board sends 5 replies 
(at one time) simultaneously with time (distance) delay equals to 30 ms. 
From this moment board responses immediately on ARP request

I use FreeRTOS 7.6.0 with lwip-1.4.1

Part of my lwipopts.h config:

#define ETHARP_TRUST_IP_MAC           1
#define ARP_TABLE_SIZE                      4
#define ARP_QUEUEING                       0
#define LWIP_MULTICAST_PING 1
#define LWIP_BROADCAST_PING 1

Also, I can see errors at field "Frame check sequence" in ARP replies, 
how can I fix this errors?

API change: restructuring ipv4/ipv6 integration

Hi all,

I just wanted to warn you I'm going to push a rather big change 
regarding ipv4/ipv6 integration where the old 'ip_addr_t' will be 
renamed to ip4_addr_t and ip_addr_t changed to replace ipX_addr_t, 
including a version information. This ensures ipv4 and ipv6 addresses 
are handled equal (more or less).

This results in an API change, which should hopefully not be noticed by 
ipv4-only users (LWIP_IPV6==0). In case it does change anything, please 
reply here!

This is in preparation for the 1.5.0 release, but I expect more changes 
in this area after possibly discussing this further on lwip-devel, so 
the API might change again in the next weeks or so. So unless you really 
want to follow development, I suggest to not pull master tip unless we 
have sorted this out.

More information on lwip-devel.

Re: How to have two different sockets for IPv4 and IPv6

I don't use the socket API but as far as I can remember, all you need 
is one socket listening on IPv6 ANY address. This will accept IPv4 
connections as well by default. It can also be disabled.

If there is no predefined sin6 address for ANY, your procedure of 
setting it to 0 is correct.

Somebody about a year or two ago had made sure this was working. Is it 
not working for you?

Cheers
Ivan

How to have two different sockets for IPv4 and IPv6

Hi,

I am trying to write a web server that listens on both IPv4 and IPv6
addresses. Although, only one implementation at a time works fine. However,
the code that I wrote for both simulateniously doesn't work. I mean I'm
creating two diff webserver tasks for IPv4 and IPv6. The socket for both
AF_INET6 and AF_INET and binding it with port=80 which is as follows:

//webserver_task_IPv4
iStatus = socket( AF_INET, SOCK_STREAM, 0 );
sin.sin_family = AF_INET;
sin.sin_len = sizeof(sin);
sin.sin_addr.s_addr = htonl(INADDR_ANY);
sin.sin_port = HTTP_PORT_NUMBER;               //port = 80
memset(&(sin.sin_zero), '\0', sizeof(sin.sin_zero));

//webserver_task_IPv6
iStatus = socket( AF_INET6, SOCK_STREAM, 0 );
sin.sin6_family = AF_INET6;
sin.sin6_len = sizeof(sin);
memset(&(sin.sin6_addr), 0, sizeof(sin.sin6_addr));
sin.sin6_port = HTTP_PORT_NUMBER;               //port = 80

Actually I'm looking for "in6addr_any" for filling IPv6 ANY Address into
IPv6 socket case but can't find anywhere in the stack and hence used
memset() to set sin6_addr to 0. So is there any replacement variable defined
for it in the stack?

Both above tasks works fine when implemented one at a time.

Can anyone please suggest proper socket binding that can listen for both
IPv4 and IPv6 at the same time.

Any help would be highly appreciated.

Thanks & regards,
Mohsin Kesarani

LWIP + IGMP

Dear all,

 

I want to receive UDP-packets from a multicast message. The system currently can receive unicast messages.

 

To receive multicast messages I’ve set the following settings in lwipopts.h

  #define LWIP_IGMP                       1

  #define MEMP_NUM_IGMP_GROUP             8

 

Also in the initialize function I’ve set the right flag

  netif->flags = NETIF_FLAG_BROADCAST | NETIF_FLAG_ETHARP | NETIF_FLAG_UP | NETIF_FLAG_IGMP | NETIF_FLAG_ETHERNET;

 

The initializing of the IGMP-group is as follows

 uint16 port;

  ip_addr_t groupAddress;

 

  getParamatersFromTransmissionGroup (group, &port, &groupAddress);

  __udpSocket = udp_new ();

  MF_ASSERT (__udpSocket != NULL);

 

  err_t err = udp_bind (__udpSocket, IP_ADDR_ANY, port);

  MF_ASSERT (err == ERR_OK);

 

  err = igmp_joingroup (&localAddr, &groupAddress);

  MF_ASSERT (err == ERR_OK);

 

  udp_recv (__udpSocket, data_received, this);

 

When I send data directly to the IP address assigned in LWIP I get to the breakpoint in data_received.

However when I change the destination IP address to the one configured in groupAddress, I get no data at all.

 

I’ve made some tests in Wireshark where I captured the packets. The test system consists of three devices

192.168.172.1 > Router

192.168.172.20 > Computer with Wireshark

192.168.172.113 > LWIP Device

I’ve attached the capturefile done in Wireshark, In this file you can see the LWIP device responds to a query.

If you need any more information, please reply to this mail.

 

Met vriendelijke groet, Best regards,

lwip ppp lower physical layer to app layer communication

Hi,

i am working on lwip ppp over serial using gsm.I am successfully able to
post to my web server.but

1)On calling lwip_read(s, Get_Post_Buffer_GSM, PPP_BUF_SIZE),it calls the
netconn_recv_data function,there is a call to
sys_arch_mbox_fetch(&conn->recvmbox, &buf, 0);on line 427
in api_lib.c.when the  function sys_arch.... returns the value inside the
buf is zero

2)on the lower side the function call sio_read succesfully reads the
expected string and post it using the ip_input 
function to the upper layer.

Question:

what would be wrong in my code that the upper TCP layer is not returning the
received buffer.that means lwip_read function not returning recevied buffer
value. pls suggest.

NOTE:I am succesfully able to post data using this GITHUB code mentioned
above.

Flushing buffer at netconn_delete

Hi Folks,

I have a server application, that communicate over HTTP with LwIP 1.4.1. My question is, that does the incoming connection flush it's buffer and does it a force send if I close the connection by netconn_close() or will be the data in the buffer lost?

Regards,
Norbert

Local "ping"

Hi All.
I have the following environment:
- host Windows-7 Professional, 64 bits, with two virtual machines(VM), Virtual Box:
   VM#1: with Ubuntu 12.04.1, 32 bits
   VM#2: with Fedora-17 Distro, 32 bits
- VM´s network configured as "NAT Network"

I have an application (POC) that uses  the lwip-stack. Inside it there is an ethernet-device, based on "ethernetif.c" to link the lwip-stack to network interface (eth) through a ethernet driver. 
I configure the netif with IP=10.0.2.62, MASK=255.255.255.0, GW=10.0.2.61

The eth-7 (VM#1) interface has this configuration:
eth7      Link encap:Ethernet  HWaddr 08:00:27:48:61:0c  
          inet addr:10.0.2.6  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe48:610c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:7187 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9353 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1153842 (1.1 MB)  TX bytes:592966 (592.9 KB)

I run the app on VM#1. 
I can ping the netif IP (10.0.2.62) from VM#2 with success. But when I ping the netif from own VM#1 I have no answer(local console), but the lwip-stack indicates (log) the arp received:
     etharp_update_arp_entry: 10.0.2.6 - 08:00:27:48:61:0c
     etharp_find_entry: found empty entry 0
     etharp_find_entry: selecting empty entry 0
     etharp_update_arp_entry: updating stable entry 0
     etharp_arp_input: incoming ARP request
     etharp_arp_input: replying to ARP request for our IP address


Questions:
  1) Is that scenario feasible?
  2) If (1) is true, why the local ping does not have reply? 

Thanks!

How could I have IPV6 in LWIP 1.4.1 offical release version

Hi,

Excuse me, I am a new Lwip developer, 
and so far I has complete porting Lwip_v1.4.1 to FREERTOS with ipv4
function.

I want to know how could I use Lwip_v1.4.1 to have ipv6 function?
Does Lwip_v1.4.1 official release provide ipv6 function?

Or I could only have ipv6 function in Git head version (1.5.0 beta)?

Thanks 
Evan
