# Configuring Gitblit using SSH authentication

This article describes how to configure Gitblit with Talend Administration Center using SSH authentication.

## Before you begin

You have installed and configured Git as explained in the Talend installation guide.

## About this task

This was tested on the following architecture:

* Talend Administration Center installed on Windows
* Git installed on a Linux box

## Procedure

1. Use the following command to add the public key in the authorized\_keys file located in your .ssh folder:

   cat id\_rsa.pub >> authorized\_keys
2. Set the permission using the following command:

   chmod 600 id\_rsa.pub
3. Download Gitblit from [http://gitblit.com](http://gitblit.com/).
4. Install Tomcat and deploy the Gitblit war file.
5. Use the following command to add the git server as known\_hosts:

   ssh -l <git\_username> -p 29418 <git\_server>.

   Run the same command on the server hosting Talend Administration Center as well to create the known\_hosts file.
6. Open Gitblit with the following address: https://servernName:port/<war\_file\_name>.
7. Use the default username and password (admin/admin) to log in:
