Enable HTTP TCP connection requests in Arch Linux for neo4j

Question

My laptop is running a local neo4j server. I can use it with localhost:7474 but when i try connecting it with 192.168.1.12:7474 it is unreacheable.

Turns out linux is blocking connections other than web server port 80. Because i can access my Apache server on 192.168.1.12/

I am trying to allow TCP connections on port 7474 by using

iptables -A TCP -p tcp --dport 7474 -j ACCEPT

but it gives a response as - iptables: No chain/target/match by that name.

How can i make other clients access neo4j server running at my laptop on port 7474. My laptop IP addr is 192.168.1.12.

Answer 1

I doubt that it is blocking it. Probably your neo4j server is only running at 127.0.0.1. You can check this out with netstat -nplt: you will probably see something (the apache) listening on 0.0.0.0:80 or :::80 (e.g. catchall address) but on port 7474 you will probably only see 127.0.0.1:7474 or ::1:7474. If this is the case you need to reconfigure your neo4j server to listen not only on localhost (don't know how, checkout the documentation).

Answer 2

Okay. I had uncommented the webserver address line but it still wasn't working. So i reinstalled neo4j. That solved it. Weird but worked.
