SSH and SCP

This looks at how to SSH and SCP on default and non-standard ports

SSH

running on default port is 22.

 ssh <user>@<host>  (e.i ssh foouser@barserver)

running on non-standard port.

 ssh -p  <port> <user>@<host>  (e.i ssh -p 2000 foouser@barserver)

SCP

running on default port is 22.

 scp <file> <user>@<host>:<host-path-to-copy>  (e.i scp foo.txt foouser@barserver:/home/foouser/directory1)

running on non-standard port.

 scp -P <port> <file> <user>@<host>:<host-path-to-copy>  (e.i scp -P 2000 foo.txt foouser@barserver:/home/foouser/directory1)

Building WSO2 Carbon from WSO2 SVN trunk

Environment

Ubuntu 10.04

Applies To

WSO2 Carbon source trunk as of 22nd March, 2011.

Prerequisite

Install the following softwares,

JDK version 1.6.x

Mavan2 version 2.1.x

Subversion

- sudo apt-get update

- sudo apt-get install subversion

Environment Setup

Open up a terminal and type,

$ gedit ~/.bashrac &

Add the following lines at the end of ~/.bashrc file, which can be located under your home directory($HOME)

JAVA_HOME=

e.g: JAVA_HOME=/home/fazlan/sw-installables/jdk-1.6.22

M2_HOME=

e.g: M2_HOME=/home/fazlan/sw-installables/apache-maven-2.1.0

PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin

Save and close the file.

Verify the version of them,

$ java --version

$ mvn --version

Checkout WSO2 Carbon

Create a directory to checkout the source code.

$ mkdir wso2-svn

Checkout the carbon source code from wso2 trunk to the directory just created.

$ cd wso2-svn

$ svn checkout http://svn.wso2.org/repos/wso2/trunk/carbon

Build WSO2 Carbon

Once the checking out of the source code is completed, you can build the code

$ mvn install -Dmaven.test.skip=true

Note: maven.test.skip=true - this will stip the test cases

WSO2 carbon needs to be build in the following order,

buidling dependencies required by carbon,

$ cd carbon/dependencies

$ cd carbon/orbit

$ cd carbon/service-stub

$ cd carbon/core

$ cd carbon/components

$ cd carbon/feature

building products,

$ cd carbon/products

where you can build a specific product by providing -Dproduct= property.

values can be = appserver, bam, bps, brs, cep, ds, esb, greg, gs, is, mb, ms

e.g mvn install -Dmaven.test.skip=true -Dproduct=greg

Possible Build-time Problems and Solutions

You might encounter certain problems while building the code,

problem: exceeding the number of open file descriptor

solution: increase the number of open file descriptor count

$ su

enter root password:

root $ gedit /etc/security/limits.conf &

Enter the following lines at the end of the file

* soft nofile 65536

* hard nofile 65536

Save and close file.

Summary

This post is aimed to help you building the WSO2 Carbon platform from the WSO2 SVN trunk and this post will be updated accordingly in the future to reflect the build statergy of wso2 carbon.
