Hello,
Is it possible to configure the Endpoints of the OPC UA server so that it will listen for connection on the given port at any IP address? It seems that it only binds to the specific IP addresses currently defined for the host, and we would like for it to work more like other apps (e.g. ssh) that listen on any IP (0.0.0.0). The netstat listing shows something like the following, where ssh is on port 22 and our server is on port 10025:

tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN –
tcp6 0 0 127.0.0.1:10025 :::* LISTEN 4027/java
tcp6 0 0 10.10.0.184:10025 :::* LISTEN 4027/java

We are running this on an ARM processor with ubuntu, and have the possibility of the network configuration changing after the server has started (e.g. could switch between wired and wireless LANs).

Thanks for your help.

I am afraid it is not possible with the 1.4.x version, but will be possible with 2.0, which enables you to specify the BindAddresses for the server, e.g.:

Set<InetAddress> bindAddresses = new HashSet<InetAddress>();
bindAddresses.add(InetAddress.getByAddress(new byte[] { 0, 0, 0, 0 }));
server.setBindAddresses(bindAddresses);

2.0 is currently in beta, so I recommend you try it out.

Thanks for the response. Do you have an idea of when 2.0 will be a release version?

We are working on new modelling features which will take some time to get finished, so there is no target date for the release yet. The communication features are solid in 2.0, but the SDK interfaces are subject to change a little bit.
