    Default *TechSims* CCNA [online router sim v0.3]

    It still needs a lot of work, but I present to you: the beta version of our online router simulator:

    www.techexams.net/testsim/techsim.php

    Just give it a shot and let me know what you think. please keep in mind that this is just a very preliminary version and still needs a lot of work.

    If you do not have a recent version of a Java VM it can be installed automatically. This works for most browsers, but you may need to install it manually.

    We recommend you install "JAVA SOFTWARE FOR YOUR DESKTOP" before trying to use our TechSims
    http://java.com/en/download/download_the_latest.jsp

    Current beta:
    version 0.3
    build 2
    Last update: March 7, 2004, 9:10 AM

    **********************************
    Supported/recognized commands:

    enable
    disable
    hostname
    configure terminal
    exit
    end
    logout
    ip classless
    ip subnet-zero
    interface ethernet 0
    interface serial 0
    interface serial 0
    ip address
    description
    bandwidth
    clock rate
    enable password
    enable secret
    router rip
    copy running-config startup-config
    copy startup-config running-config
    shutdown
    show version
    show running-config
    show startup-config
    ?

    Special keys:
    <TAB> - auto command completion (currently only in User and Priv Exec mode, other will be added very soon)
    <CTRL-Z> - exits configuration mode
    <CTRL-B> - move one character left
    <CTRL-F> - move one character rigth


    restart sim



    The following commands are supported but do not relate to the CCNA exams, they are added for the BSCI exam:
    router isis
    is-type level-1
    net
    ip router isis
    isis circuit-type level-1
    isis circuit-type level-2-only

    - When a command is entered that is currently not supported, the sim will reply with "% Command not supported".

    - At any time, you can use the command "restart sim" to restart the TechSim, with the default minor configuration.

    - Not all abbreviated versions of the currently supported commands are recognized, if your favorite one is missing let me know and I'll add it.

    Added ip address command, more show running-config output that can actually be changed, isis command (for BSCI routing exam).

    Currently working on improved password support, including vty and console password, password encryption and better relationship between enable and secret.

    Made some significant changes to the interface, making it look more 'real'.


    Comments anyone?

    Well, I made through all 10 steps successfully. unfortunately, I can only say it "looks" good, since I have no idea what it should look like.

    well done, it looks exactly as a router promt looks like, i have a question about this, i did all of the techsim test very well, i took three courses about cisco routing technologies and cisco wna administration but finally after finish it i tought "what can i do with this if it is not applicable in the real world" i mean this scenarios are not seen everydays working in the computers environment, at least not in regular places with a bounche of pcs, i know this interface is known for a network administrator and something else so i am happy to answer that test good but where exactly can i apply this knowledge if i dont see these routers and promts everywhere, i also bought a linsys router and it has a kind of web page set up that doesn't allow me to manipulate a lot of things, specially about wireless, anyway any further help will be great .

    thanks and good job in this forum and actually in this place its great always look for the stuff you guys have for study purposes

    thank you very much

    Unfortunately, I beleive that a grasp of true networking is impossible without hands on experience. That's just my opinion. The routers are there, but if you specialize im cisco particularly, you might find yourself lacking in other important skillsets, such as server administration. (Excuse the runon sentence)

    To Webmaster:
    I tried the sim, and unfortunately it didn't work for me, I couldn't press enter. I'm using the Sun java runtime development libaries on a fresh install of XP. I haven't had an opportunity to try it on linux browsers but I'll do that tomorrow.

    Ramsesk,

    The prompt in our TechSim is similar to what you get when you connect to a router by using a console cable (http://www.techexams.net/technotes/c...hardware.shtml)
    or when you connect to the router by using a telnet session. What you see is the command-line interface to configure the IOS, Cisco's OS. Experience with other brands of routers is often not very useful when it comes to configuring Cisco routers.

    So do I
    You probably need to click on the right side of the blue arrow before you click enter. I know it is kind of a limitation right now, but I'm sure I'll solve that eventually.

    I just uploaded a new version of our online router sim for the CCNA TechSim. I has some major improvements compared to the previous version:

    - Added a startup configuration (and copy start run, copy run start, show start commands)
    - Added support for auto command completion (TAB key) (doesn't work for some commands in config modes yet.)
    - Added support for CTRL-Z to exit config modes.
    - Added support for CTRL-B (left) and CTRL-F (right)

    - Improved password system (enable, secret. Others will be added soon, including better encryption options)
    - Improved ip address configuration command. Now actually validates the format of an the IP address and subnet mask (subnet mask validation will be improved soon, currently accepts ip address as subnetmask)
    - Improved the 'looks' (larger window, horizontal cursor, black background/white text)
    - Improved the use of the ? command, now works in all modes (not for partial commands yet)
    - Removed the need to 'click right from the blue arrow' to begin.


    Things I'm working on:
    - terminal history support (commands and shortkeys)
    - CDP commands
    - more show commands (interface, hosts etc.)
    - password encryption
    - more TechSims (labs in our sim)
    - lots and lots more....

    After I added all the commands for the CCNA exam, I will add a second router to the sim (see diagram) which can be configured by starting a telnet session from router1. Then I'll also add more routing related commands and eventually, hopefully, access-lists....

    Let me know what you think of it...

    ... and I thought the Dutch were only good at soccer :P

    Really nice work. Though I always have two windows (applets) of the RouterSim running simultaneously ... must be an Opera problem. (And to test it I can't log in to the site on another browser since I'm already logged in here)

    Well, you thought wrong

    I have to admit I haven't tested it on all non-IE browsers. Although 98% of our visitors use IE, I will download a couple of other browsers to see if the sim works.

    Try clicking the bottom line of the black part (right above Welcome...) and then press Enter. I suspect your browser doesn't allow th focus to be set to a java applet element.

    Default Interconnecting Cisco routers!

    Hey,
    I would be very grateful if someone helps in this one:
    I have 3 cisco 2500 series routers to configure. Of all the interfaces configured all of them are up BUT only 2 of them have LINE PROTOCOL UP, the rest have line protocol down.
    I have tried checking over and over plus reconfig from scratch and yet no solution.
    How can I troubleshoot this problem... ? What could be the problem?

    Thanks for your comments guys. I will have a look later today and hope you can try it after that. There are several ways to load a Java applet, and it now seems that I haven't done it in the most optimal way.

    Ok, I've made some changes to the code that loads the applet into the Java plug-in. Please try again and let me know it it works. Be sure to delete your temp internet files before trying. If it still doesn't work, please provide your OS and browser version.

    Very impressive! I'm sure that someday, when I get into the Cisco stuff, this will come in very handy!

    Thanks for all your hard work!

    A couple of Java issues to begin with, but easily corrected with a quick download and install.

    Other than that, it is an excelltent sim for folks starting out and wanting to get the feel of "cisco."

    Thank you for your hard work in developing it. I am sure it will be much used.
