Hi Brenton,
The DNS server configuration shouldn’t be an issue in this case, as we provide the IP address of the server – in such case the DNS query isn’t even sent as we already know the IP address.
I’ve reproduced the problem locally, and it turned out there was a problem with ARP retransmission handling, wrong source address was selected for the retransmission, I’ve posted a PR with a fix proposal:
https://github.com/zephyrproject-rtos/zephyr/pull/40038
Another thing is that the reason for the ARP retransmission even being sent is the fact that e1000 driver does not process any incoming packets early after boot (for about 1 second). I have to little knowledge the particular device/driver
to figure out why is this happening, but I’ve asked the question in the aforementioned PR, perhaps we’ll get some answers there.
Regards,
Robert
Hello,
I am attempting to download a file hosted on a localhost file server.
- I am hosting a file named "Zephyr" using "python3 -m http.server 8980"
- I am using a zeth interface and the "overlay-e1000.conf" to allow
qemu to communicate with
localhost. I successfully tested the LWM2M client example to ensure the connection was good.
- I can download the Zephyr file when I input "http://192.0.2.2:8980/zephyr" into a web browser.
- I attempted using the "overlay-ci.conf" file to perform the download.
CONFIG_SAMPLE_BIG_HTTP_DL_URL="http://192.0.2.2:8980/zephyr"
however I get the following error:
Preparing HTTP GET request for
http://192.0.2.2:8980/zephyr
addrinfo @0x6da008: ai_family=1, ai_socktype=1, ai_protocol=6, sa_family=1, sin_port=1423
Iteration 1 of 1:
sock = 0

[00:00:00.000,000] <inf> net_config: Running dhcpv4 client...
Error: connect(sock, ai->ai_addr, ai->ai_addrlen)
exit
I managed to get the example to download the online vmlinuz file, however I cannot get the sample to download via localhost.
Do you have any suggestions on what steps I could have missed?
Could it be a DNS issue? for downloading the online vmlinuz file I used 8.8.8.8 as
CONFIG_DNS_SERVER1.
For localhost, I left it at 192.0.2.2
With thanks
Brenton
