How unoriginal I am for short titles… Well, if you have your own DNS server or DHCP server, This is your post 😉 We're not really going to get it through logs, we will do this by auditing your traffic 😉 We will audit the requests generated by the DNS service, or DHCP to view it in Grafana!
¡Oh! A back to the basics! As promised, we started a series of podcasts that will be and will start from the base to get to know certain IT services, Today it's time for the pillars: DNS, DHCP and NTP.
Good! Nothing, I wanted to share with you a little fight I had in a summer project, among several things he had to migrate a Windows DHCP server 2003 to Windows 2016 Server, I share with you the steps I followed to migrate it to the new server in less than a crows! Think of each DHCP environment, with each rank, with all the exclusions, Customizations… How to avoid resetting it!
What's up txabales!!! How do we usually find out that a DHCP server is down or a scope is full?? Thank you to our dear users, No? As the idea is that our users are the last to notice any problems in our organization (apart from the bosses)… we will take advantage of our monitoring facility based in Nagios or Centreon to control yet another critical point in an organization, DHCP Service!
In this document we will show how to assign IP addresses with our DHCP servers to computers that we are interested in, based on certain conditions such as belonging to an AD group, if they have an antivirus installed, If you have the S.O.. up-to-date… we may indicate whether we are interested in giving you an IP address of our areas or denying you access to the network,
One of the great new features that Windows brings 2012 Server is the possibility of having the DHCP service in high availability (Finally!), since it is one of the most critical services of organizations. We can create a load balancing between two DHCP servers or mark one server as active and another passive, the latter waiting for the fall of the asset to provide service.
This procedure explains how to move the DB from our DHCP to another server, It doesn't matter the S.O. of origin, how if we migrate from NT4 to NT4, NT4 to 2003, a 2000, of 2003 to 2003… The first thing we will need is the DHCPexim, The tool that migrates, download from AKI. And we start installing it on the server from which we want to migrate the DHCP service, then once exported to a text file we will install the DHCPexim on the destination server to import that file, More details:
When we set up a net, Or when we migrate one and it has a fixed address, we remember how good it would be to have a DHCP server set up and forget about the issue of going post by post modifying any network data. DHCP is used to save a network administrator work, IPs are configured from the server, a range of IP addresses to be assigned to the positions is established and that's it, We can also include, all the data that interests us apart from the IP, such as, What is the gateway, DNS, WINS and many more. We can assign the duration of the IPs in the clients, by default are 8 days. We can reserve IPs by MAC addresses. And see the list of assigned IP addresses.
