Re: [lwip-users] Handling sudden disappearance of network i/f

[Janusz U.]

I added
 pxSRVconn = netconn_new(NETCONN_TCP);          // init conn
 if (pxSRVconn != NULL)
  if (pxSRVconn->pcb.tcp != NULL)
   pxSRVconn->pcb.tcp->so_options |= SO_KEEPALIVE;      // turn on 
keep-alive

and not keep-alive is working. But I don't understand why when I close 
socket on my windows serwer the lwIP does not notify that. Only when I close 
my serwer the lwIP close too (RST state?).

cheers
