Linux can be configured as a network workstation, a DNS server, a mail server, a firewall, a gateway router, and many other things. Network administration is one of the main tasks of a Linux administrator.
In this Video Learning Path, you will begin with configuring and deploying several network services including file, web, mail, and servers. You will then learn how to enable NAT on the router in order to allow Internet access from the network.
Going ahead, you will learn to configure Samba to centralize authentication for your network service and Linux client to leverage it for authentication.
You’ll also set up SMTP and IMAP mail services, and enable spam filtering. Then we’ll configure our own XMPP-based IM service, configure it to communicate with other XMPP services, and configure Pidgin as a client to utilize the service.
Finally, you will have a network with a number of services running on it, and will implement monitoring in order to detect problems as they occur.
By the end of this Video Learning Path, you will learn to build, maintain, and secure a computer network using Linux.
For this course, we have combined the best works of this esteemed author:
Gregory Boyce is a technologist with nearly 20 years' experience using and managing Linux systems. He has spent the last 15 years working at Akamai Technologies, where he has worked in roles ranging from network operations, internal IT, information security, software testing, and professional services. Currently, he heads up the Linux OS team that manages Akamai's custom Linux operating system, which runs on their massively distributed customer-facing network.
In this video, we will configure IPV4 in both the servers.
We will see how to connect two networks, here we will configure 3 servers and interchange the data.
It works the same way as setting up a DNS server for an internal hostname, just with a few additional parts that we'll want to make sure are in a good state.
In this video, we will look at how the synchronization of settings works, and what it will coordinate on your behalf.
In this video, we will join machine to the domain using Administrator credentials to participate in an AD-style domain.
In this video we're going to look at ejabberd, which is an extremely powerful and flexible option that has great online documentation.
Nagios is an industry standard for open source monitoring and reporting. It is incredibly flexible and extendable, for better or worse.
Monitoring your local system, you have full access to information regarding number of processes, amount of memory, CPU usage, and so on. When you're looking at remote systems, you're limited to accessing remotely accessible information like if a remote port is listening, ping ability, and so on.
You need to define a name for the service and the command to run in order to monitor it.
SNMP is useful for monitoring network equipment like routers and switches, which often have SNMP agents built into them.
Linux servers are typically configured to use a syslog based logging system for handling events.
