I think putty & teraterm the popular free ones. Hyperterm may still be out there.

There is the telnet client from the command prompt. I'm pretty sure you can telnet from the command line with Vista too (since I telnet to my Linux boxes all the time and don't remember installing any additional telnet software).

SecureCRT seems to be the popular software to pay for -- but that could be because an older version is used in the CCIE Labs.

If you search the forums for putty you'll probably find most of the previous threads where people asked about the best/free/most popular terminal emulation programs. If you limit your search to the Cisco forums, you'll also find most of the "popular tools" for/of Cisco Professionals threads.

i figured out how to do it with the hyperterminal.
i have another question mike
i'm reading the wendell odom book part 1 and he just showed me how to configure basic password and hostname. I went along and i did on my 2950 and it all worked. Then he moved on to ssh configuration process. for some reason when i type the transport input telnet ssh comand i get an error. What could be the problem?

I believe it's not installed by default. You need to go to Control Panel > Programs > Windows Components to enable/disable it.

i'm having trouble with the ssh configuration process

mikej412

You need an IOS image that supports the crypto functions. Most of the newer IOS software will support it for security, but not all the older IOS images had it (since there were also export restrictions on encryption technology in those days).

If you have an image that supports ssh, check out Configuring Secure Shell on Routers and Switches Running Cisco IOS - Cisco Systems

You need a crypto image to run SSH, what is the IOS version you have?

post an output of "show version'

does mine support it? i'm just following everything the book says
emma#configure terminal
enter configurationcommands, one per line. end with CNTL/Z.
emma(config)#line vty 0 15
emma(config-line)#login local
emma(config-line)#transport input telnet ssh
emma(config-line)#exit
emma(config)#username wendell password hope
emma(config)#ip domain-name example.com
emma(config)#crypto key generate rsa


that's what the book tells me to do to set up ssh. But i get the error message after i enter the transport input telnet ssh

rotinhell2568

do you guys know how i can fix this?

dtlokee

You need an image with crypto (typically will have 'k9' in the filename).

In the past you could download the switch IOS from Cisco's website without a service contract but I don't know if that is the case anymore.

rotinhell2568

so do you know what i can do then?

dtlokee

Go to the Cisco website > support > download IOS > switches software then login with your CCO account or create a guest account if you don't have one. It may allow you to download the softerware, I am not sure

mikej412

You can check the IOS Feature Navigator to find if your IOS supports ssh.

But since it appears that a guest level Cisco CCO login still gets you to the Switch IOS images, here's the latest versions available.

Your version's feature set seems to match the non-crypto image.

I posted the download steps/path in the http://www.techexams.net/forums/ccna-ccent/31002-ios-2924xl.html thread. I think it works better if you log in first, using the log in link on the main page, rather than waiting for the challenge. That way if you follow a wrong link, you get the not authorized message rather then login prompt and then the not authorized message (and you wonder why it didn't work).

Do you have an IOS upgrade using XMODEM section in your book?

Doing an IOS upgrade using XMODEM was a lab when I did the Cisco CCNA Network Academy. Doing it once in a lab environment is usually enough to make a person think twice on the job before doing something stupid like accidentally erasing the IOS image on flash.

An XMODEM IOS image upload is one of those things you will remember for the rest of your life.

Matt George has his Cisco IOS Recovery via XMODEM video in the http://www.techexams.net/forums/ccna-ccent/39100-some-free-cbts-finally.html thread.

Get PuTTY or SecureCRT if you can. Hyperterminal is a terrible terminal emulator.

PuTTY and SecureCRT will also allow you to telnet/SSH into your devices as well so you don't need to mess with multiple programs. One program will do it all.

rotinhell2568

mike which out of the four you listed should i download?

rotinhell2568

Cisco Catalyst 2950 12 Switch, Release 12.1.22-EA12,
C2950 EI AND SI IOS CRYPTO IMAGE

is this the correct one?

mikej412

You want either of the CRYPTO images.

If you're not on a dialup modem, download both CRYPTO versions and use whatever version works easiest in any matching lab your book may have.

The Web Device Manager is fun to look at once or twice.... but if you're going to XMODEM, then stick with the CRYPTO only image since it's smaller.

I think we also did a Cisco CCNA Network Academy Lab that used the tar file for the install (the CRYPTO and Web Device Manager) -- you couldn't do that with just the CRYPTO image .bin file.
