I have an application running on a home network. the client is windows and the server is Centos 7. I can access the application from a browser, but when I try a HTTP POST from another Centos 7 box (CLI) I get 54 ECONNRESET Connection reset by peer RECV. after reviewing TCPDUMP i see that Centos drops the connection after trying to do a reverse DNS lookup. The problem is that I am not using DNS but direct IP addresses. How can I force Centos not to do a reverse DNS lookup? Best, ITschak
