Note: In Slave machine Git only installed(Jenkins not installed)
In the key configuration you should put the private key not the public key
And in the slave machine you don't need to install Jenkins

I installed jenkins on my raspberry pi and when I opened the jenkins page, the introduction page comes up. The weird thing was that it said that my jenkins is offline and I should configure a proxy. That's weird because my raspberry pi has an internet connection and everything works fine. But then I tried to download github plugin for jenkins and no plugin was installed successfully. This is the exception:

But when I try to go to that site (http://updates.jenkins-ci.org/download/plugins/github/1.25.1/github.hpi) manually, everything downloads just fine. Any ideas why my jenkins cannot access internet and seems to be offline?

You failed to connect to your destination. Nobody can tell you anything different without some actual code.
It seems that your server is not running or you are giving wrong server info so you are getting
java.net.SocketTimeoutException: connect timed out
If you attach your code snippet it would be helpful
How can i detect this exception when i start my application:

The project is configured in the Spring way (http://projects.spring.io/spring-amqp/) and I can see the errors in the logs, but I can't detect it in my java Classes.
Consumer raised exception, processing can restart if the connection factory supports it. Exception summary: org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection timed out: connect

This can happen for example when you have no access to the AMQP port.
Thank you!
There is currently no event emitted when this error occurs (I have created a JIRA issue to add one.
In the meantime, since the the connection is shared, you could call createConnection() on the connection factory from your own code from time to time, to check the connection state.
Or, you could hook into the logging subsystem to capture the WARN log, as I described in this answer.
I just started using Jenkins and I'm seeing an issue where my slave services is crashing while running a job(the job executes an .exe program). The error I'm seeing is as follows -

Any help or insight on why this is happening would be great!
Eric
I am using Jenkins. Go the particular node,
Click on Configuration then in JVM options enter -Xms512m -Xmx1024m
That will increase the heap size.
