[lwip-users] TCP reconnect issue

[farid mahini]

Hi,

 

I have created a TCP server (lwIP 1.3.0)  using socket APIs that allows only one client connection at a time.  Most of the time, I can connect, disconnect and reconnect with any problems. However sometimes after unclean disconnects (either client app is stopped or crashes), I am not able to reconnect to the TCP server. Cycling server power does not help. The ping does indicate the unit is up and configured.  If I change the server address and reboot, I can connect to teh new address. I recall it takes awhile for Windows to release an orphaned connection, but I can not connect to that server from any computer. Any ideas on what could be happening?

 

Thank you,
