a DNS (or DNS-like) service updated with the mapping {client-name => current ip address} Handing this on the OpenVPN server(s) is relatively easy with a --client-connect script on the OpenVPN servers. The client connect script is passed the IP address of the new connection. You can then use that to call nsupdate to adjust your DNS records. Here is an ...

There is some ambiguity in your question, but the following presumes you are talking about setting up a high-availability MS SQL environment on a Hyper-V failover cluster. You are correct in so far as you will need a domain controller separate to the failover cluster nodes - for example, to reliably authenticate to the cluster nodes (some sysadmins set up ...

You need at least three servers. 1x Domain Controller 2x SQL Servers This, of course, assumes a lab or dev environment. In production, you will want at least one additional domain controller.

Starting after 2008 R2 Microsoft changed "Services and Applications" to "Roles". Also in the referenced example, "Under Actions (on the right), click Move this service or application to another node" is now "Under Actions, click move, then either best possible node or select node".

Assuming that the apex A record for example.com. was pointing at a broken IP address, most companies I know would change the A record and skip the www change entirely: Most admins would rather not have their website broken for users who key in the name of the website without the www prefix. This goes double for admins who don't trust their webapp devs to ...

I agree. As long as the "real servers" have stable IP addresses the A records should have long TTLs. Keep the TTL on the CNAME records low to enable fast switching to another real server in case of failure or whatever.

The error message peer holds all free leases can also mean that the request has been received on the wrong network interface, e.g. if a computer is only configured to get an IP on eth0, but the DHCP request is received on eth1. deny dynamic bootp clients is typical for such a setup. In my case one interface was for the workstation network and the other one ...

Do i have to add any separate iptable rules for different IP's (VIP and Static Public IP)? That depends on how your existing iptables rules look like. If your'e explicitly allowing access to specific IP addresses, then yes, you need to add rules to the VIP. If you just accept connections to the specific port, then no. How to allow (listen) traffic only on ...

This is a strange request... Mainly because there shouldn't be issues that result from vMotion (manual or DRS-triggered) in a vSphere environment. A vMotion should be safe. If there are issues stemming from it, you need to fix those instead of reacting to guest-level problems. This doesn't answer your question directly, but you're chasing the symptom ...

I know this is an old question, but it comes up fairly high in results of a Google search on this subject, so I would like to offer a more complete set of circumstances on why you might want either configuration: For those who want to have two connections to two switches in case of any type of failure of network equipment to have full redundancy (like me) ...
