I just now installed the latest ES distro on an Ubuntu box with OpenJDK 6b27. It's failing to reach host -- that's an error that googles well, but with nothing that I've seen to help. The box is sitting at 10.1.10.179 and is pingable on its local network from a host windoz box (firewall off). It can ping out. But, ES refuses to boot. Using ifconfig and route, I've managed to see the host to 10.1.10.1, which is the default gateway on the windoz box running this network. I'd appreciate some hints at what I might be missing. BTW: the same build on another windoz box is running faultlessly. Thanks Jack -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Can you telnet from either host to the other on 9200/9300? Also, that's a super old JDK, if you have to use OpenJDK then upgrade, but you should ideally be on Oracle's 7 release 25.

Interesting stuff. I'll simply report what I did for the record. I did install the latest Oracle jdk, but, I think I didn't fully do the install; it's not like windoz where you just install it and set the system paths, etc. There's more with Ubuntu, which I did not do. But, when I purged OpenJDK, it unmasked an Oracle java 6, so I left that. The network issue resolved, finally, to some really hairy details of setting up eth0 on that box, which is sitting on a local gigabit network. I finally got that running, then opened up ES ports in the Windoz firewall, and am happy to report it's running fine now.
