Cisco CCNA Certification Exam Tutorial: DNS name and IP-Server Command

DNS behavior of a Cisco router are important issues for both the CCNA exam and real production networks worldwide, and you probably did not know there were so many DNS details before you began studying for Review! In this tutorial we'll look at the ip name-server command and its proper use.

When a command is mistyped on a Cisco router, the default router is attempting to resolve the DNS. First, the router looks for a table of IP host on the local router to perform this resolution - that's what the "translating" word in the output refers. If there is no table d'hote or IP of the IP host table contains no entry for what is typed, the router sends a broadcast to resolve this name through a DNS server remote. To avoid this broadcast, enter the global command no ip domain-lookup. Of course, to use DNS to resolve hostnames, ip domain-lookup will be reactivated if it has been disabled.

Contin R2 #

Translate "continues" ... domain server (255.255.255.255)

% Unknown command or computer name, or unable to find the address of the computer

A command is misspelled as "Contin. Default behavior of Cisco router is to resolve this entry locally via an IP host table, which is not present on the router. A program is then sent to find a server to perform DNS name resolution. The DNS lookup attempt must time out before the configuration can continue.

R2 # conf t

R2 (config) # no ip domain-lookup

Contin R2 #

Translate "continues"

% Unknown command or computer name, or unable to find the address of the computer

With "no ip domain-lookup" configured, the router does not try to find a remote DNS server. She sees no local resolution configured and almost immediately sends a message to the console that the name can not be resolved.

R2 # conf t

R2 (config) # ip domain-lookup

R2 (config) # ip name-server 10.1.1.1

Contin R2 #

Translate "continues" ... domain server (10.1.1.1)

A DNS server is installed on the network with IP address 10.1.1.1. DNS Lookup is reactivated with the field of IP-Lookup command and the IP address of the DNS server is specified with the ip name-server command.
It's just that easy to tell a Cisco router exactly where the DNS server is!

This article is therefor biramous into two parts. We instrument care at the option options to construct themes in Windows 7 in the front line and analyze bag recipient themes in the endorsement split of the article.

The Windows 7 News Guide To Windows 7 Themes: Default Options

The Windows 7 operating system comes with a selection of themes installed. These pre-installed themes can be activated instantly in the operating system in the Personalization menu. The easiest way to access this menu is by right-clicking on the Windows 7 desktop to open the context menu that contains a link to Personalize the operating system.

The accustomed options to fill, fit, corrupt, tile or country are accessible.

Window Apologise and Appearing

Window colors define how menus in the Windows operating system look like. Microsoft has made it easier for users to change the colors by offering to save to several color themes with the click of a button. This will change the window borders, start menu and task bar if executed. The menu provides access to enabling the transparency, changing the color intensity and a color mixer as well.

The old Windows Color and Appearance menu that users of previous Microsoft operating systems are used to work with is still available under advanced appearance settings. This menu can be used to customize the window color and appearance further.

Sounds

The sounds menu is one of the menus that looks almost like the version in previous Windows operating systems. It can be used to configure system sounds for specific events in the operating system like critical battery alarms, windows startup or devices that disconnect. The only apparent change is the number of additional sound schemes that have been added to the operating system.

Screen Saver

The screen saver configuration menu looks almost exactly like the menu in Windows XP. Windows 7 users can pick a screensaver and define the wait time before the screensaver becomes active. Access to power options are provided which have also been provided in previous operating systems.

Desktop Icons

This menu can be used to configure, display and hide desktop icons. Here it is possible to select the icons that should be displayed on the computer desktop. This includes a Computer, network or recycle bin icon. All of these icons can be changed in the very same menu. It is furthermore possible to block themes from changing desktop icons.

Windows 7 – Be Ready

Key challenge with deploying a new operating system is preparing for the upgrade in your enterprise, from legacy applications, deployment schedules and seriously down to the how are you planning to roll out a new OS. While in the lab testing we discovered a few use cases that highlighted how you could deploy new OSes after normal work hours - Minimize end user and IT productivity impacts and maximize deployment saturation in the shortest period of time using Intel vPro Technology to initiate a remote PXE or media boot or an integrated power on command.

We dug in deeper and found the following value points from our lab test for deploying after you have vPro enabled:

• Perform remote OS deployments on bare metal hardware

• Perform remote OS deployments on PCs where the OS or PC agent are non-responsive

• Meet defined or mandated OS deployment timelines regardless of PCs’ power state or connectivity (wired / wireless)

While I realize that having vPro enabled is not always possible before an OS upgrade, therefore we are going to be posting how to deploy Win7 and enable vPro at the same time to assist with your deployment. We will be updating the following wiki as the new use cases are completed.

Microsoft to Best Buy Staff: Here's Why Linux Sux

(Edit, to draft, Slurp)

Microsoft is offering Best Buy employees Windows 7 for $10 if they complete training that includes selective truths about Linux. Apparently Windows 7 is totally safer, and Linux won't work with cameras, iPods, or games like World of Warcraft. WTF?

True, there's no elegant solution for the iTunes Music Store under Linux. And that's a fair enough point. But when it comes to player software, Linux has plenty of options, including Banshee. And the iPod, most MP3 players, and printers work fine under Linux.

True, Linux won't run every Windows program, but Wine supports a bunch of them. Special versions like CodeWeaver's CrossOver Games actively support World of Warcraft.

Video chat on all major IM networks? Try Pidgin or Skype. Windows Live Essentials? There's plenty of free alternatives.

There's some extra steps involved in the above, so I'm not saying that Linux is suitable for each and every newbie, particularly those who would ask Best Buy for advice in the first place. But some of Microsoft's info is a little…distorted. [

Microsoft's training materials teach Best Buy employees how to trash Linux

Look, nobody's saying Linux is perfect for every consumer (or even most), but Microsoft's "training material" for Best Buy employees casts the open source operating system in a bit of a bad light -- and isn't exactly accurate. A few of the humorous tidbits in the Linux comparison guide include mentioning World of Warcraft as incompatible with Linux (despite great support for it under WINE), calling Linux's safety reputation a "myth," and describing Linux updates and upgrades as difficult and time consuming. The availability of Windows Live Essentials as a "free download" is also quite laughable -- Linux has endless free alternatives to Microsoft's Live Essentials, and many of them are better than what Microsoft offers. Not to say there hasn't been the odd consumer that was burned by purchasing a Linux-running netbook, but we'd say there are enough tangible benefits to Windows for Microsoft to avoid misinformation when talking down the open source competition.
