Exception getReplicaName in Glacier2

[mamp]

Hello,

I'm using Glacier2 to allow access to an IceGrid Registry placed in a private network.

On the side of the registry, I have set the property IceGrid.Registry.SessionManager.Endpoints to enable the IceGrid/SessionManager. On the side of Glacier2 I have defined client and server endpoints, session manager and session timeout, and the IceGrid.Default.Locator.

The registry and the Glacier2 run ok. In fact, I can connect via icegrid-gui with the registry directly. However, when I try to connect via icegrid-gui with a Route session I receive the next exception:

Could not retrieve replica name: Ice.ObjectNotExitsException
id.name = ...
id.category=IceGrid
facet=""
operation=getReplicaName

After checking the logs I have observed that in the first case the registry receives an admin connection. On the other hand, when I connect via Route, the registry receives a client connection (without access to the Ice::Admin facet). I suppose that this is the problem, but I can not figure out how to solve it.

I'm attaching the configuration and log files for both the Registry and the Glacier2.

Best regards,

Miguel Ángel

Hi,

If your goal is to keep the IceGrid registry endpoints accessible to the private network, you should make sure to configure the registry endpoints with only internal network interfaces (using the -h <host> option for each of the registry endpoints).

I believe the reason why it doesn't work is that you're not using the right endpoints for the admin session manager. You should configure IceGrid.Registry.AdminSessionManager.Endpoints instead of IceGrid.Registry.SessionManager.Endpoints if you want to allow administrative access to the IceGrid registry with Glacier2.

Also you don't need to specify a port for the session or admin session manager endpoints. Finally, I also strongly recommend to use SSL to secure the admin session manager endpoints to ensure that only the Glacier2 router process can access these endpoints (otherwise, any Ice process might access these endpoints and create administrative sessions to your registry).

See here in the Ice manual for more information on how to secure IceGrid.

Cheers,
Benoit.

Hi,

I have replaced the property IceGrid.Registry.SessionManager.Endpoints with IceGrid.Registry.AdminSessionManager.Endpoints, and now everything works.

Thank you very much for your quickly and precise reply.
