xtcp_wait_for_connection hangs

[stefanharjes]

Hi all,

after I upgraded the tcp/ip stack from 2v0 to 3v1 I have a problem building up a tcp connection. I simply call:

Code: Select all

  xtcp_connect(tcp_svr, 8080, server, XTCP_PROTOCOL_TCP);
  conn = xtcp_wait_for_connection(tcp_svr);

where I try to connect to a tomcat server on my local box (192.168.7.1). With2v0 the connection was build up at once, whereas with 3v1 the system waits at the second line for ever. I have looked at the tcp traffic using tcpdump and have attached the dump for both versions.

One can see the successful dhcp connection buildup. Then the xtcp_connect call begins with the lookup of the server address, but I do not know enough details about tcp/ip to understand why there is no tcp connection being made. Any hints would be appreciated

Thanks

Stefan
