With the introduction of Red Hat 6 a new utility was introduced to configure networking. It is called the Network Manager, is running as a service and appears on the desktop in the upper right corner:
Since it is a service it can be stopped and started to reset the network settings and it can also be disabled. It cannot to do all settings you might want to configure, for example bonding of networkcards.
Besides the Network Manager there are other ways to configure the network. You can edit the network configuration files manually, or use the old “system-config-network” tool.
We'll go through the different options in this article.

This is the documentation page about the setup from mercurial on Red Hat systems here. Mercurial is a versioning system which uses a master repository server. The usual setup is shown in this picture:
Once you know how everything works, setting up Mercurial is quite easy, and consists of these steps:
- Installation
- Install Mercurial on master repository server
- Install Mercurial on client server
- Repositories
- Create AD Service account for mercurial on master repository server
- Create repository
- Cloning
- Create SSH trust between AD service account on master repository server
- Create clone
- Configure clone
The Red Hat Enterprise Linux 6.5 Management Server will function as the master repository server, while all other servers will function as a client, since we want to create a versioning system of all /etc directories.
Note that the element abbreviation for Mercurial is hg. Using mercurial will be done with the command hg.
