All network services are working well EXCEPT web traffic on port 80 to one particular Linux box. We have other web services running on other Linux boxes that work fine. Traffic over port 80 to various machines, no problem there. But this one Linux server (which happens to host our primary enterprise web application) … not working. Wireshark output looks like its just not responding. Stuffed if I know whats going on. Successful connection caprtured in Wireshark attached along with failed capture. Network packet capture on the Linux box (native) looks like its receiving the request but just not replying. Perhaps they had a falling out, I dont know the history. Anyway … I respectfully request abundant knowledge and suggestions … cause I aint got shit. universalMember September 4, 2017 at 4:52 am #388834 Can you ping the Linux box and vice versa? If not, check the routing table/gateway setting. If the Linux server does respond to pings, you should check the firewall settings.
