If you are the proud owner of a New ICY NAS-Box 4220 (referred to as NAS from now on on this page) you may have discovered that telnet does not work. You will find this out if you try to venure beyond the Web Interface provided by the box. telnet is used to access network devices as well as providing simple command line interface to UNIX or LINUX. This is similar to the cmd Window on Windows XP or (for those of us old enough DOS.
This page shows you how to enable Telnet Access to your NAS-4220.
The instructions are aimed at a novice user. Experts can just get on with it - you were a novice once!
As initially installed "out of the box" the NAS-4220 does not support telnet however so first we need to enable it. This is quite simple.
|1||Connect to your NAS 4220 box using your favourite
browser. Enter the URL http://<nas> – replace <nas>
by your NAS box name or IP address. The screen shown should appear.
Enter your standard administrator <user name> and <password> (default is admin/admin).
Click Login Button.
The next screen to appear will be the standard– replace <nas> by your NAS box name or IP address. NAS screen.
|2||Enter the following URL in your web browser – replace <nas>
by your NAS box name or IP address. Note that the part following <nas>/
can be copied [CTRL+C] from the text
below and pasted into– replace <nas>
by your NAS box name or IP address. the URL [CTRL-V] in your browser to
f– replace <nas>
by your NAS box name or IP address.inal part of the URL displayed
http://<nas>/cgi/telnet/telnet.cgi followed by [Enter]
The telnet enable screen will now appear.
|3||You now need to click the Enabled
Checkbox (this has already been done on the screenshot).
Click Save button
Close down your browser. The NAS now supports telnet connections.
Windows contains a telnet program but the user interface (in particular copy/paste) is awful. It is far better to use a freeware program - PuTTY - which is a very comprehensive telnet access program (and a lot more beside) and is universally (well almost) for this sort of task when using Windows. I have never seen an open source licence like it - free for home, industry government!
If you are using LINUX then read no further - you already have a telnet client program.
Right - let us install PuTTY.
PuTTY is a free, small download from the internet. The screenshots and description is for XP using Internet Explorer 7. Vista may vary in detail. My system is in the UK using UK localisation. You will have to interpret these into your own language if your computer is configured for another language.
|1||First we need to download the program. Using
your favourite browser enter the following URL http://www.putty.org/
Clink on link - You can download PuTTY here
This takes you to the download page.
|2||Scroll down to the binaries section. There are several
choices here which are equally valid. Click
on the option putty-0.60-installer.exe
under the heading A Windows installer for everything
The File Download dialog box will appear.
|3||When the File Download dialog box appears choose Save to your local drive (at least that is my preference). Choose a suitable location to store the download. The download is 1.67 Megabytes.|
|4||You can then choose Run to start the installation. A Security Warning dialog pops up to confirm that you want to run the software. Click on Run to continue.|
|5||A standard Windows Setup screen appears - click Next to continue|
|A standard dialog box showing the installation location
appears. Only change to installation path if you have good reason to do
so. The default is usually OK
|Confirm that the Start Menu folder is acceptable (orchange it is you must) by clicking Next|
|Choose the options you want. I find the d</a>efaults aare
|Confirm installation by clicking Install<</a>/a>|
|Installation procedes in the normal way and we end with
this screen. Click Finish
Shut down the Readme when you have read it. PuTTY is now installed.
Uninstall uses standard Windows uninstall should you ever feel the need.
I would make one standard tweak to the defaults PuTTY uses. this is my personal preference and is not essential. There is a further tweak to make it slightly easier if the NAS is the only device you want to use PuTTY with.
through the Start Menu.
The screen shown is the main control/configuration Window. You use this to select the device to talk to and the type of connection. The pane on the left allows many parameters to be configured. We will be changing one of these.
Click on Window on the Category pane.
The next screen appears.
|The Window now shows the default initial state. The
line I recommend sho</a>uld be changed is Lines
of scrollback. With PuTTY you can look back through the
history of what you have been doing. 200 lines is sometimes not enough.
unless you are short of memory I always set it larger. The actual value
used is personal preferance. I recommend a value between 1000 and
10000. I personally always use 10000 which is far larger than I have
ever needed. Let us choose 10000
- type it into the Textbox.
Return to the Session (i.e. the initial) screen by clicking on Session.
|We are on the final stage now. Change the Connection Type to Telnet by
clicking on the Telnet Radio
Go to the Host Name [or IP address] textbox and enter the IP address you have configured onto the NAS or its Name - in this example <NAS> is used, you should use your own.
Finally click on Save. This will save to configuration settings so you don't need to go thorough this again when you start PuTTY again..
Start PuTTY trough Start Programs unless you already have the Window open following configuration.
You open a PuTTY session by Clicking Open and a new Window will open showing a login prompt.
In the sample shown below the device name has been replaced by <nas>. In your case it will the device name you have entered or the device default.
The login command has been issued using root as the login name and admin as the password (i.e. this is the same password to that used to login as admin on the web configuration screen). Note that the password does not echo the characters typed for obvious reasons.
<nas> login: root
BusyBox v1.00-rc3 (2007.08.08-11:22+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.
You now have a prompt to access the UNIX command set. Just follow the instructions or learn how to use the more basic commands, there are no help files on the NAS (man pages in UNIXspeak) but Google will usually find what you are looking for.
