How to connect with ssh from your ubuntu host to guest os with virtualbox

1. VirtualBox > Settings > Network > Add (you will get vboxnet0)

ifconfig #will show you new interface vboxnet0

2. Shutdown your VM and do:

VM's Settings > System > check "Enable I/O APIC."
VM's Settings > Network > Adapter 2 > host-only vboxnet0

3. Start VM, on guest run

ifconfig
and check ip

4. Configuring port forwarding with NAT in your host machine

VM's Settings > Network > Adapter 2 > Port forwarding and add a rule and give following values to guest port and host port
Host port - 2222
Gurest port - 22

5. Now connect to the VM guest os with ssh using the following command

ssh -p 2222 root@localhost

WSO2 ESB tuning performance with threads

I have written several blog posts explaining the internal behavior of the ESB and the threads created inside ESB. With this post, I am talking about the effect of threads in the WSO2 ESB and how to tune up threads for optimal performance. You can refer [1] and [2] to understand the threads created within the ESB. [1] http://soatutorials.blogspot.com/2015/05/understanding-threads-created-in-wso2.html [2] http://wso2.com/library/articles/2012/03/importance-performance-wso2-esb-handles-nonobvious/ Within this blog post, I am discussing about the "worker threads" which are used for processing the data within the WSO2 ESB. There are 2 types of worker threads created when you start sending the requests to the server 1) Server Worker/Client Worker Threads 2) Mediator Worker (Synapse-Worker) Threads Server Worker/Client Worker Threads These set of threads will be used to process all the requests/responses coming to the ESB server. ServerWorker Threads will be used to pr

How puppet works in your IT infrstructure

What is Puppet? Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting. Using Puppet, you can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage change, scaling from 10s of servers to 1000s, on-premise or in the cloud. How the puppet works? It works like this..Puppet agent is a daemon that runs on all the client servers(the servers where you require some configuration, or the servers which are going to be managed using puppet.) All the clients which are to be managed will have puppet agent installed on them, and are called nodes in puppet. Puppet Master: This machine contains all the configuration for different hosts. Puppet master will run as a daemon on this master server. Puppet Agent: This is the daemon that will run on all the servers, which are to be managed using p

How to configure timeouts in WSO2 ESB to get rid of client timeout errors

WSO2 ESB has defined some configuration parameters which controls the timeout of a particular request which is going out of ESB. In a particular scneario, your client sends a request to ESB, and then ESB sends a request to another endpoint to serve the request. CLIENT->WSO2 ESB->BACKEND The reason for clients getting timeout is that ESB timeout is larger than client's timeout. This can be solved by either increasing the timeout at client side or by decreasing the timeout in ESB side. In any of the case, you can control the timeout in ESB using the below properties. 1) Global timeout defined in synapse.properties (ESB_HOME\repository\conf\) file. This will decide the maximum time that a callback is waiting in the ESB for a response for a particular request. If ESB does not get any response from Back End, it will drop the message and clears out the call back. This is a global level parameter which affects all the endpoints configured in ESB. synapse.global_timeout_inte
