Hi All,,

I have the FreeRTOS running on cortex, with webserver from freertos example. Everything works fine, Im able to display pages. But this is only when I run client browser on Linux machine. When I try to connect from Windows there is always a timeout. On windows I disabled the firewall, antivirus etc. but no luck. Also I have linux running on virtual machine, and this works as well. I've tried wget from windows (GNU build) and I am also able to pull a html file. Finally Wireshark claims that GET is sent... but on FreeRTOS webserver the rxStream is NULL and lBytes is 0 (for that request). Any ideas?

Thanks, Pawel

Interesting - we have tried from Windows too. Which browser are you using?

It would be helpful if you could post your wireshark log as an attachment - filtered to show just the HTTP traffic to your target.

A wget from your windows does work, while a Windows browser can not open the same embedded page? That sounds strange.

What value did you use for backlog in :

~~~~ static const struct xSERVERCONFIG xServerConfiguration[] = { #if( mainCREATEHTTPSERVER == 1 ) /* Allow for 12 simultaneous connections: / / Server type, port number, backlog, root dir. */ { eSERVERHTTP, 80, 12, configHTTP_ROOT }, #endif ~~~~ ?

When I try to connect from Windows there is always a timeout.

Do you mean that you never get to see that page?

Yes please, attach a PCAP file showing the HTTP-session that gets a time-out.

You may want to filter on e.g

ip.addr==192.168.x.x && tcp.port==80

Regards.

Seems like I've found the problem. Since we are low on ram I've minimized the MTU and WIN_SEG sizes, and this affected working with windows. The GET from windows has more info from browser, and from linux its smaller. Therefor the linux version was just fine. I will bring back the default server sizes (cleaning up other parts of code), and let you know if all is good.
