Now we are talking about webhosting management in changing the hostname. The Change Hostname option enables you to change the hostname of your server. It is important to choose a hostname that will not be used for any account, and the hostname must be socially acceptable, as it will appear in all mail headers. The hostname must be a FQDN (Fully Qualified Domain Name). All valid hostnames must have at least 2 dots in them, for example entropy.yourdomain.com. find these qualified domain name at web hosting rating.

Your Web Hosting Manager automatically generates 10 random hostnames based on

your current hostname as samples which you can use. Your hostname should be a Fully Qualified Domain Name that will not be used elsewhere on the server. You should never set your hostname to an name that is already used (www, ftp, mail, etc) or to the name of an account on the server (www.domain.com).

Here are steps to overcome:

1. To access the Networking Setup Menu, click on Networking Setup, on the main            screen of your WebHost Manager interface.

2. Click on Change Hostname.

3. Enter your changed hostname in the New Hostname field.

4. Click on Change.

In some take down scenarios, anticrime responders determine that a domain name is being used for fast flux attacks, go to the registrar or registry where  website hosting the domain name is registered, explain the nature of the problem, and convince the registrar to take the domain name out of service. Registries and registrars are not bound by policy to respond in a particular way to complaints regarding fast flux hosting and the fast flux hosting technique in and of itself is not an illegal activity until it is clearly associated with an illegal activity (computer abuse and fraud, identity theft). Registries and registrars set their own policies regarding abuse and implement response procedures independently. However, some common practices exist. Registries will require sufficient information to clearly demonstrate that the domain name is being abused or is abetting criminal behavior and will typically conduct their own investigations. If the registry’s own investigation corroborates the data presented by the responder or claimant, the registry may take that evidence to the registrar of record who will typically act quickly to resolve the trouble reported. The registrar’s own policy and the ICANN RAA (if applicable for the TLD in which the domain name is registered) affect the registrar’s response, which may be to suspend the domain (i.e., use HOLD status to prevent the DNS from resolving the name); suspend the domain name and change the registration record to reflect that the domain name is dispute or the registration policy has been abused; or suspend the domain name and delete it from the zone.

Registries typically respond to requests from law enforcement, subpoenas, and court orders in an expeditious manner. Many registries and registrars have general abuse departments, and FAQs and contact forms are often browser-accessible. Registries and registrars might provide similar FAQs and forms to facilitate and expedite communication with LEA and anticrime responders. Rapid modification of A resource records that resolve to the fluxed referral name servers thwarts detection and hampers measures to shut down fast flux webhosting sites.

NTP or Network Time Protocol to give it its full name is an internet protocol designed to distribute precise time around a network. NTP is a UDP based protocol used to synchronize system time on network infrastructure, such as servers, workstations and network equipment .

This article describes how to utilise the Network Time Protocol authentication features to authenticate time references when synchronizing clients to a NTP Server.

NTP Server Security

Network Time Protocol is used to provide a precise time reference for time critical applications. Therefore, NTP can pose a security risk if malicious users attempt to corrupt a NTP timestamp to create a false time on network equipment.

NTP provides increased security in the form of authentication. Authentication is intended to overcome security risks by ensuring that any response received from an NTP time server has come from the intended reference. The client sends a request for time to a NTP server. The server then responds to the client with a precise timestamp along with one of a number of agreed encrypted keys. On receipt of the timestamp, the client un-encrypts the key and verifies it against a list of trusted keys. The client can then be sure t Continue reading »
