FreeRTOS webserver windows issue

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 ~~~~ ?

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.
