No error/warning when remote gateway not accessible #337

Open asmodehn opened 8 years ago

asmodehn commented 8 years ago

One gateway publish its information on Redis hub. This information contain its ip/hostname.

If this IP/Hostname is not resolvable&accessible from another host, no warning or error is displayed. Just nothing happens ( no flipping/pulling log message ).

We should have an error/warning displayed so that the user know when/where he needs to correct his network configuration.

PS : This situation happened when running in virtualbox (1 robot, 1 concert), without having /etc/hosts setup to have both vbox find each other. Please comment here if you can confirm warning/error is displayed in a "wrong network setup" situation.
