Dynamic DNS Configuration On IPFire Firewall

dynamic dns configuration on ipfire firewall
We have recently discussed in details the benefits of using dynamic dns for an environment where the IP address changes frequently as with the use of dsl modems, and the likes.

This guide, discusses how to configure dynamic dns on pfsense router, another popular open source unified threat management gateway solution.

In this guide, ”Dynamic DNS Configuration On IPFire Firewall”, we will not go into discussing the benefits and use of dynamic dns, but we will simply implement it in IPFire and test it out with a practical use case.

Setting Up A Share on Samba4 Active Directory Domain Controller

Setting Up A Share on Samba4 Active Directory Domain Controller
In previous guides, we learnt how to install samba4 on a new debian server. We also learnt how to manage(add users, computers, GPO e.t.c) our samba4 active directory server using rsat on windows.

In this guide, we will do some more by enabling  file sharing capabilities on samba4 active directory controller. This guide will aim to enable file sharing on the domain controller, much like on a windows domain controller.

Note: This may not be the best practice. I feel that it will be better to setup a seperate file server using samba4 or windows server flavors. However, we will go on with setting up a file share on our active directory server for a small office network.

Python Script to Remotely Administer Servers Using Telnet and SSH

Python Script to Remotely Administer Servers Using Telnet and SSH
Every network administrator who manages cisco routers, switches and firewalls, Linux routers/firewall, Mikrotic routers, e.t.c, understands the benefits of running commands over secure shell(SSH). Our routers are configured by the admin, to allow SSH access, and a remote ssh client is used to administer and issue configuration commands to the servers whenever we want.

What we may not know, actually, is that we can harness the full powers of python and the full powers of SSH to make out automation (automatic configuration) much more fun. In a recent study, it is believed that automation techniques, scripting, is a necessary skill for every network and system administrator. It not only makes your work more fun, it also saves time and energy, allowing you to be more productive.

The general rule of thumb is that any task that is repetitive should be automated. My opinion though!
