can't access a service to a remote host


I have this network. host1 <-> router1 <-> router2 <-> router3 <-> router4 <-> host2. I can ping from host1 to host2, but I can access a service that is running in the port 50070.

Both hosts run linux in terminal mode.

I did tcptraceroute, and I get this output. It seems that it has connected, but when I access the service with a browser, I get Connection refused.

Am I reading right? The output got show that I connected to the destination?

HadoopWorkers-rci-0:~# tcptraceroute 10.103.0.20 50070
traceroute to 10.103.0.20 (10.103.0.20), 30 hops max, 60 byte packets
1 HadoopWorkers-fiu-0 (10.103.0.20) <rst,ack> 1.087 ms 1.016 ms 0.960 ms

Could be a firewall issue, or a NAT problem?
You need to check the rules on all routers and on servers.
Also check the logs on host2, if it doesn't give anything then run tcpdump on all routers to see how far the request goes.
