Adding username and password authentication to Cisco routers and switches doesn’t take more than a few minutes, does not require a software upgrade in most cases, and will increase router and switch security.
Boosting authentication increases security by forcing hackers to guess both the username and password rather than just a password. And authentication can be passed to a central server so that users and passwords can be created and modified in one spot without having to change the configuring on every router and switch in the company. Additionally, this type of authentication is needed to configure Secure Shell access to routers and switches, which encrypts administration traffic. Cisco supports username and password authentication on almost every device so a software upgrade is probably not needed before configuration. But Secure Shell requires a software upgrade in many cases.
This article will include configuration examples for local and TACACS+ server authentication. A nice example for configuring RADIUS authentication on routers and switches or passing authentication back to the company’s Active Directory can be found at TechRepublic..
In many cases, administrators impartial configure a telnet password for their network devices, which is the least secure plot to permit access. Here is an example of the method those routers are configured.
RouterA#configure terminal
RouterA(config)# line vty 0 4
A router’s telnet interface is called a vty, short for Virtual Teletype Terminal.
RouterA(config)# password letmein
RouterA(config)# end
This will allow access to router via telnet by just the password letmein. Below is an example of configuring a router for username and password authentication from a local database stored on the router itself. If you have more than one router or switch, each router will need to be configured. Either way is more accept than just a password by itself. A more complex password increases security, so use passwords that are difficult to guess and create usernames that are not as simple to guess like admin or cisco..
RouterA#configure terminal
RouterA(config)# username Jane password Doe
RouterA(config)# username Bob password Smith
RouterA(config)# aaa new-model
RouterA(config)# aaa authentication login default local
RouterA(config)# end
The configuration creates the usernames Jane and Bob with the passwords Doe and Smith respectively. AAA stands for authentication, authorization and accounting. The line ‘aaa authentication login default local’ specifies that local authentication should be used for login by default. The passwords will show up in the configuration just as you typed them and be readable by everyone that has access to the router configuration file unless the service password-encryption command is used. For example:
RouterA#configure terminal
RouterA(config)# service password-encryption
RouterA(config)# end
Now your passwords will be encrypted in the configuration. There are hacker tools available that can decrypt these passwords, so configurations should still be stored in a secure place.
Here is a eye at configuring TACACS+ authentication. In this example, the switch or router will first look to TACACS+ for authentication and then if that fails, it will look in the local user database. This will give you access if your network device loses network connectivity to the TACACS+ server. This example assumes there is a working TACACS+ server already running on your network. If not, notes on configuring a TACACS+ server on Linux can be found here.
RouterA#configure terminal
RouterA(config)# aaa new-model
RouterA(config)# aaa authentication login default group tacacs+ local
RouterA(config)# tacacs-server host 10.1.1.1
RouterA(config)# tacacs-server host 10.1.1.2
RouterA(config)# tacacs-server key SecretPassword
RouterA(config)# end
If the switch or router has access to the authentication server, then the next time that you log in, the device should prompt you for a username rather than just a password. Complete details on configuring aaa access can be found on Cisco’s website.

Cliff Bleszinski, also known as “CliffyB,” of Story Games and a major figure in the PC gaming world, has made some controversial comments about the situation of the PC gaming industry. Bleszinski is quoted in Gamasutra as saying “I consider the PC is just in disarray.” He further comments that “what’s driving the PC right now is Sims-type games and World of WarCraft and a lot of stuff that’s in a Web-based interface. You objective click on it and play it. That’s the direction PC is evolving into so for me, the PC is kind of the secondary part of what we’re doing. It’s distinguished for us, but honest now making AAA games on consoles is where we’re at.”
While one can say that he may have made these comments simply to relieve drive up sales on his console games, which he mentions in the quote above, does Bleszinski’s statements speak the truth about a larger argument? That is, what is better, PC or console games? Besides, what is he future of the PC gaming market?
I have been enthusiastically playing console games for nearly 20 years, ever since as an eight-year-old being introduced in 1989 to a pair of mushroom-eating, koopa troopa-stomping Italian plumbing brothers named Mario and Luigi. Since that time, I have watched console gaming grow up from 8-bit games to multi-effect environments into which players are incredibly immersed. The beauty of all this? These console games can be played on self-contained systems that increasingly appeal to most every demographic imaginable. While some may laugh at the cost of buying some of today’s high-end console game systems, like the Playstation 3 (which was at one point easily selling for more than $600), compare the costs of game systems to those of computers, both desktops and laptops, which can cost in the lower thousands.
And what about the idea of kids getting off the couch and getting some activity? Well, at least there are console games that young and older players alike move around having fun with their video games, including the Nintendo Wii Sports. How many PC games allow their players to do anything but sit in a chair staring at a conceal?
Of course, there are many great PC games, some of which I have played myself over the years. I loved a game called Coaster, one of my earliest PC titles which I played back in the mid 90s. My father and sister are both Freecell, Minesweeper, and Riven fans, and Dad liked Doom. Sis loved the King’s Quest series.
PC games have their audience, but that’s just the point: PC games seem to be filing a niche role while console games are taking off. That is because console games are self-contained, portable (Traveling? Simply take along the console, some games, and a few cords and connect the system to most any relative’s, friend’s, or hotel’s television), and offer dozens—even hundreds—of titles. Console games today are so super-powered, they can literally bring the player into the imaginary video game world thanks to ravishing special effects, ever-improving sound technology, and crisp resolution.
PC games will always have a market, but it will increasingly become a niche market that targets young adult males; meanwhile, console games will continue to reach and entertain game players of every age, including seniors, who now are looking to games like Nintendo’s Brain Age to help keep their minds sharp. With the Atari, ColecoVision, Nintendo, Sega, and Playstation all major players in the console gaming market, the industry has thrived for thirty years. Meanwhile, the PC gaming market has had to work hard to keep players interested in their games over a period of time when computer operating systems have changed dramatically, making it difficult for many people who simply cannot afford to constantly be updating computer systems to play the multiple sequels that some titles, like those stemming from Myst, Doom, and King’s Quest, which have been released over a number of years.
While console game systems also have over the years undergone technological changes which require players to buy whole new systems to keep playing new titles, at least once a game console and its games have been purchased, one can go succor and indulge in the games practically forever.While the desktop computer my family now has is based on a platform to large too handle my decade-old, floppy-based Coaster game, I quiet can and do play games on our Nintendo Entertainment System, Super Nintendo Entertainment System, Nintendo 64, and Playstation 2. Ah, the joy of owning a self-contained gaming console.
