RE: different IP than expected
I use those arrays to read the request and send the response, there is no stack
overflow error. I've defined a IP value inside the server file (#define) and
it worked as intended, but I want to be able to read the IP from Kconfig
instead of having it in the server file, I'll be looking for a way to do this.
Thank you all for the support!

Something as simple as stack overflow might be the issue. There are
some huge arrays on the stack that might be causing issues:
struct sockaddr_in address;
int opt = 1;
int addrlen = sizeof(address);
/char buffer[2048] = {0};//
//char response[4096] = {0};/
const char *file = "/data/client.html";
So it is going to need a stack allocation of something like 8Kb.

This is useful if your system has multiple network interfaces and you want to provide some kind of isolation. "address.sin_addr.s_addr = INADDR_ANY;" + "bind" is a way that you say "I want to receive requests from any interface". That is the way other server logic works. See apps/netutils/netlib_server.c and apps/netutuils/netlib_listenon.c. The only part that confuses me is that INADDR_ANY is zero. address is passed to bind() as read-only, const. So address.sin_addr should still be zero.
Re: different IP than expected
setting "address.sin_addr.s_addr" + "bind" is kind of a way you can use to
receive requests only from an interface that has a specific IP address.
This is useful if your system has multiple network interfaces and you want
to provide some kind of isolation.
"address.sin_addr.s_addr = INADDR_ANY;" + "bind" is a way that you say "I
want to receive requests from any interface".
So this does not have any relation to the interface you configure via
menuconfig. Obviously if you will set "address.sin_addr.s_addr" to address
configured via menuconfig it will work.

So setting a value for the IP address in Kconfig and assigning it to
address.sin_addr.s_addr should solve the problem?

I think that you misunderstood the data flow a bit.
So you have
...
address.sin_family = AF_INET;
address.sin_addr.s_addr = INADDR_ANY;
address.sin_port = htons(PORT);
if (bind(server_fd, (struct sockaddr *), sizeof(address)) < 0)
{
perror("bind failed");
exit(EXIT_FAILURE);
}
...
printf("waiting for requests at %s:%d...\n", inet_ntoa(address.sin_addr),
PORT);
So you assign INADDR_ANY to a address.sin_addr.s_addrand then call "int
bind(int sockfd, FAR const struct sockaddr *addr, socklen_t addrlen);" that has
"const" modifier for "addr" parameter hoping that it will modify the value that
you just assigned. That just simply will not work.

Hi,
"INADDR_ANY" definitely does not match "listens to the defined IP" statement. I
do not understand exactly what you are trying to do, but it would be good to
know what is the output of "ifconfig" running from NSH.
If you do not want to share code details, maybe you can check how your
application behaves on Linux and compare to what behavior you observe with
NuttX.
Can this somehow be reproduced with one of the apps available in the NuttX repo?

Re: different IP than expected
When I started with networking, I set the IP via kconfig. I remember that it was necessary to enter the same IP at two different places. Netlib and FTP server in my case.

Do you have any API call to get the IP? Because I read that like "int a =

If there is no API call to update "address" then you simply will print

Hi, "INADDR_ANY" definitely does not match "listens to the defined IP" statement.

different IP than expected
Hello everyone! I configured NuttX to a certain IP address and I have a webserver which listens to the defined IP: [cid:820c9f69-369e-403b-8928-15a97245100a] [cid:a42eded4-3e24-4b28-b0a7-07170d21a404] The HTML file above has a variable that contains the server IP address, but it is a different one: [cid:5e9d6cae-0b80-47cd-a05d-f9d52e1fdf80] the server replaces the text SERVER_IP_ADDRESS to it's actual IP and then sends the file to the client. This is the method I used to get the IP address: [cid:f59e2b66-2f08-4aa7-895c-936b962eab26] Why is it a different IP? The server is listening to one but this method returns another one.
