Using dynamically assigned port in guest executable in Service Fabric - azure-service-fabric

From the a guest executable, a Rest Server, how I can get the port assigned by Service Fabric?
I need to configure my executable to use this port. I guess I could use the port number as a parameter to execute my app, but I have not found it.
A workaround is
https://medium.com/#mattmazzola/service-fabric-using-dynamically-assigned-port-in-guest-executable-91a881e2a27a but it is not officially supported, so it could not work in a next version.

Following environment variable should be set before the guest executable starts
Fabric_Endpoint_[YourServiceName]TypeEndpoint

Not able to access a rest service in Microsoft Azure VM

I am having problem to access a node js rest service deployed on an ubuntu virtual machine. I am able to access the VM using putty, however I am not able to ping the reserve ip from command line. I have put the logs in the rest service as when it gets the hit it prints the log, the logs are not getting printed. I want to know if there is any additional setting which needs to be done to open a port from the virtual machine or it is supposed to be open by default. If I need to open the port in order to access the service, where should I look for it.
Thanks & Regards

No, Azure will not open other ports by default, we should open ports manually.

It is a classic VM, am I right? if so, we should make sure the rest service listening on which port, and add endpoints via Azure portal:
More information about create an endpoint please refer to this link.
If your VM in ARM module, we should add a inbound rules to NSG.

Consul.io - how to run multiple servers on same machine

This is probably a very basic question for you, but I'm just getting into consul and for testing purposes, I wanna run multiple servers on my PC. For example, I run the first server with
consul agent -server -bootstrap-expect=1 -dc=dev -data-dir=/tmp/consul -ui-dir="c:/consul 0.5.2/dist"
and then I try to run the second server with
consul agent -server -data-dir=/tmp/consul2 -dc=dc2
but it returns
==> Error starting agent: Failed to start Consul server: Failed to start RPC lay
er: listen tcp 0.0.0.0:8300: bind: Only one usage of each socket address (protoc
ol/network address/port) is normally permitted.
What am I missing from my command?
You are launching two consul servers using mostly default values. In this case the problem is that you use default ports.
When you read the error message you will notice that your second consul server tries to bind to port 8300. But your first server is already using this port, causing the second server to fail at startup. (note: consul binds to a variety of ports, each having another purpose and default setting. Take a look at the documentation).
As suggested by LenW, you can use Vagrant to set your environment. You could follow the consul tutorial.
If you do not want to use vagrant or set up any virtual machines on your own. You could change the defaults of the second server.
If you are trying to simulate a production topology on your dev machine I would look at using Vagrant in combination with VirtualBox to simulate a couple of machines for testing.

apache camel - deploying with cxfs web service

I'm trying to deploy my camel app which on start is creating a cxfrs endpoint. The url is like this: http://localhost:9876 . When I try to hit this one on a rest client or anywhere within my machine it works. But when I try to access it using my phone or other external devices, I'm not able to connect.
Am I missing something?
TIA
Using localhost will mean it is only accessible to your local machine, using 0.0.0.0 instead should make it publicly accessible.
0.0.0.0 should bind all available network interface on your remote machine, but from your description, somehow it only bind to localhost|127.0.0.1 so only accessible from local machine, could you use
http://external.ip.address:9876/foo/FooService
instead to see if it helps?
Also, you can try to access other network service(for example start a tomcat on remote machine and see if you can access it from your local machine) from that remote machine to see if it works, this can determine if your DNS correct or if there's really no firewall between them.

java.net.BindException when trying to run Jboss on remote system connecting it using RDC

I am trying to run JBoss(5.1) on remote system connecting it using RDC. Which ever port I try, it's says already in use and throwing java.net.BindException Cannot assign requested address: JVM_Bind
I have tried to change the port using jboss service binding configuration located at below path:
jboss\server\Server_Instance\conf\bindingservice.beans\META-INF\bindings-jboss-beans.xml
I have tried various options like ports-01, ports-02 ,ports-03 and then customizing the default port configurations as well with No luck.
I am just wondering how it is possible that it's not allowing any port whichever I try. One thing I would like to let you know here is that the remote system has 3 different logins and all of the users are using the system.
Appreciated if you can provide me any assistance please.
You can pass the -b ${IPofMachine} to bind to an IP. This will also make it externally accessible. You can do 0.0.0.0 which will bind to all available IP's

Powershell: Is it possible to have a service depend on remote services

I'm using Win32 Service object and there's Change which could be used to set Dependencies. Is it possible to set the service to depend on services running on a different machine? Currently, all the services run on the same machine but it's possible to run them each on a separate machine.
Nothing like that exists today, AFAIK. It is a good ask. Check this MS connect item: http://connect.microsoft.com/WindowsServerFeedback/feedback/details/293384/remote-machine-service-dependency
That said, you can create a script or another service to poll remote machines for dependent service startup and then start the local service.
