Glacier in two machines

[yeranarraila]

Hi!
I'm trying to run a client and a server using glacier. If I run it in same machine, its works. But if I pu client in machine A and server in machine B, I receive this error below. Telnet is working fine and firewall is disabled:

Hi Tatiana,

It's difficult to spot the issue without seeing the code well.

Could you take the demoj/Glacier2/callback demo, modify its configuration and try to run it? If this does not work, please post your configuration and the error message you get - we already have the code.

For the server (Callback.Proxy, Callback.Server.Endpoints), you don't need an external interface or port reachable directly by your client. Glacier2 is an intermediary (router) between your client and your server, and it's Glacier2 that uses the Callback.Proxy to talk to the server, typically on an internal interface.

Best regards,
Bernard

Hi!

I run the demo, and receive this error:

This demo accepts any user-id / password combination.

#
# Glacier can forward requests buffered or unbuffered. Unbuffered
# means a lower resource consumption, as buffering requires one
# additional thread per connected client or server. However, without
# buffering, messages cannot be batched and message overriding doesn't
# work either. Also, with unbuffered request forwarding, the caller
# thread blocks for twoway requests.
# The default is to use buffering (=1), in both directions.

# regular routing, as well as for callbacks (reverse routing).
#

#
# To prevent Glacier2 from being flooded with requests from or to one
# particular client, Glacier2 can be configured to sleep for a certain

# forwarded. During this sleep period, new requests for the client are
# queued. These requests are then all sent once the sleep period is
# over. The unit is milliseconds.

#Glacier2.Client.AlwaysBatch=1
#Glacier2.Server.AlwaysBatch=1

#
# Glacier2 always disables active connection management so there is no
# need to configure this manually. Connection retry does not need to
# be disabled, as it's safe for Glacier2 to retry outgoing connections
# to servers. Retry for incoming connections from clients must be

Server and router are running in the same machine. Client is in other machine.

[bernard]

There are a few problems with your configuration:

- The Ice.Default.Router endpoints must match the client endpoints of your router

# '-h localhost' means listens only on loopback!
Glacier2.Client.Endpoints=tcp -p 4064 -h localhost

should be

Glacier2.Client.Endpoints=tcp -p 4064 -h 150.162.64.184

- likewise, the Callback.Proxy endpoint should match your server endpoints. Here, I would update the Callback.Proxy to:

Callback.Proxy=callback:tcp -h localhost -p 10000

(remember it's the Glacier2 router, not the client, that calls directly on this proxy)

Cheers,
Bernard
