Greet,
Looking for some help on how to setup two hobbit servers.
First I will explain what I have and then what I am trying to
accomplish.
Currently.
I have a rack of servers on the east coast with a hobbit server and a
second rack of servers on the west coast with it's own hobbit server.
Each hobbit server only reports on the servers in its rack. The two
hobbit server do not know the other exists.
What I would like to do is make the east coast hobbit server be the
"master" server.
Is there a way that I can have the west coast hobbit server send it's
display to the east coast hobbit server.
I would like to see both racks displayed on the east coast hobbit
server display. I do not want the west
coast clients to send data to the east coast hobbit server.
Thanks,
Lee
I think the easiest way to do this would be run a bbproxy on the west coast server. Change hobbitd on the west coast server so it listens on a port other than 1984, then start a bbproxy that forwards all incoming data to both the new port on the west coast server and to port 1984 on the east coast server. You will also have to update bb-hosts and the like on the east coast server.
Thanks, Larry Barber

Insert a bbproxy between the clients and the hobbit server on your west coast installation, then configure bbproxy to forward incoming messages to both servers.
Right now:
- West coast hobbitd listens on 1.2.3.4 port 1984
- West coast client sends message to IP 1.2.3.4 port 1984 (hobbitd)
With bbproxy:
- West coast hobbitd listens on 127.0.0.1 port 1984
- West cost bbproxy listend on 1.2.3.4 port 1984
- West coast client sends message to IP 1.2.3.4 port 1984 (bbproxy)
- bbproxy forwards incoming messages to 127.0.0.1 port 1984, and to east coast hobbitd on 5.6.7.8 port 1984.
Note that you do not need any changes to the clients.
Changes needed:
- Add a --listen=127.0.0.1 to hobbitd in your west coast hobbitlaunch.cfg
- Enable bbproxy in your west coast hobbitlaunch.cfg. Use the option "--bbdisplay=127.0.0.1,5.6.7.8" to tell it to forward requests to both servers.
- Change the BBSERVERIP setting in your hobbitserver.cfg to point at the 127.0.0.1 address. This setting is used e.g. by the web CGI's that talk to the "real" hobbit server, so it is best to point this at the real server IP, not the proxy.
- If you run network tests from the same server, then you probably need to change the CMD setting in hobbitlaunch.cfg also. Instead of calling bbtest-net directly, put it into a shell script wrapper and set BBDISP explicitly to the 5.6.7.8 address before running bbtest-net. Otherwise, it will pick up the BBSERVERIP setting and send the network test results to 127.0.0.1 - so they won't go through the proxy, and hence you won't see them on the east coast server.
- Restart Hobbit

Thanks Henrik and Larry for the replies.
I will definitely give that a try.
Thanks!
