SSH
Telnet is a secure form of Telnet, using an RSA key.
Telnet is a more powerful means of access than FTP, and as such
there are more possibilities for error, and actions which may
cause harm to the server. Please note that SSH Telnet access
to an account is a privilege which can be revoked if we determine
that the user's activities are detrimental to the health of
the server.
The first step is to let us know you need SSH
Telnet access - your account must be enabled for this access.
The second step is to download and configure an SSH Telnet application.
Third, you will need to create a key using your PC's SSH software,
then use SSH feature within your Control Panel to upload the
key to our servers. Once it is uploaded, you will be able to
connect to our servers using SSH.
There are many good programs available on the
Internet; three we've heard good things about are:
As an example we have provided instructions below
for setting up SecureCRT to access an account.
SSH Settings:
Protocol: ssh1
Port: 22
Cipher: 3DES
Authentication: RSA
Here are the Basic Steps to set up SSH on your domain.
1. E-Mail support to request SSH access. (Include
your domain and username) Allow sufficient time for support
to add SSH access to your domain.
2. Launch you SSH Software
and set up per the program instructions. We have provided instructions
for Secure CRT and PengiNet on this site.
3. Create an RSA Key per the program instructions.
4. Go to your control panel and click on SSH and
paste your RSA key in the box indicated.
5. You will then need your access addresses. This
is the IP number from which you are accessing the server. (not
the IP address for your hosting account) If you cannot determine
the IP address you are accessing from, you may be able to input
your ISP "from" address using this form:
*.aol.com
*.earthlink.net
IMPORTANT: after submitting new information, wait
about 10 minutes until the server updates
6. Log in with your software, using the passphrase
used when you created your RSA Key.
Setting Up SecureCRT Software
First you must Create an RSA Key with Secure CRT:
1. Launch the Secure CRT application. The application displays
typically with the Connect dialog box open to the Session List
tab.
2. Select the New button to create a new session. The Session
Preferences , new dialog box displays.
3. In the Name field, enter name of the session you are creating.
4. In the Protocol field, select ssh from the drop-down list.
5. In the Hostname or IP field, enter your domain name or the
IP number for your domain.
6. Complete the rest of the fields on this screen with the appropriate
information. Make sure to enter your domain user name in the
Username field and to select RSA from the Authentication fields
drop-down list.
7. Select the Advanced button. The Advanced SSH Options dialog
box displays.
8. On the General tab, select the Create Identity File button
from the Identity Filename section of the dialog box. The SecureCRT
RSA Key Generation Wizard displays.
9. Click on the Next> button to proceed with the next step
of the Wizard.
10. If you wish to use a passphrase as an added layer of security,
enter the passphrase in the Passphrase and Confirm Passphrase
fields. Be sure to enter it into both fields in exactly the
same way. Dont forget to keep your passphrase handy. You
will need it when establishing a connection to the server.
11. In the Comment field, either accept the default value or
enter a new one. The comment will be your way of knowing when
the application is prompting you for your passphrase.
12. Click on the Next> button to proceed to the next step.
(Note: the Back button can be used throughout this wizard to
move back to the previous step and make changes if necessary.)
13. You need to determine the length of your RSA key pair needs
to be determined. It is recommended that you choose a value
between 1024 and 2048 bits. 512 bits is the absolute minimum
and is not recommended.
Once you have entered a number, select 'Next' to proceed.
14. As the instructions in the wizard indicate, you need to
move your mouse around on the screen for the application to
generate the key. The application uses a complex set of formulas
to create the key out of your mouses movements. When you
have moved your mouse around sufficiently, the screen automatically
changes and the key pair is generated. This is shown in the
image below. You do not need to move your mouse around for this
second part of the step.
15. When both progress bars are full, the Next button
becomes enabled. Select it to proceed.
16. Select the folder on your hard drive in which to store the
key. You can accept the default, which is usually the identity
sub-folder of the SecureCRT folder, located wherever you installed
the application originally.
17. To complete the wizard, select the Finish button. The Advanced
SSH Options dialog box reappears.
18. From there, select the OK button to close the dialog box.
The Session Preferences new dialog box reappears.
19. Select OK to apply the changes and end the procedure. Your
newly created session will now appear at the bottom of the Session
List.
How To Place the RSA Key on the Server:
1. (If you left the SSH Manager open from earlier sections in
this manual, you may skip this step.)
From the Control Panel, select the SSH icon. Once again, the SSH
Manager displays.
Place your key in the text box that is provided
in the SSH Manager and submit it. (To do this, you must open
the key in another application, copy it, and then paste it into
this text box.)
2. Launch any text-editor. On a Windows-based PC, Notepad will
suffice. (This is available from the Start menu, under Programs,
then Accessories.)
3. From the Notepad File menu, select Open. The Open dialog
box displays.
4. Find the key file by switching the Files of type field to
All Files (*.*). Then, move through the directory structure
to the location of your file, identity.pub. (The application
stated where the file would be stored in the previous procedure.)
When you located the file, double-click on it to open it in
Notepad. (Note, the image below has been altered, so the key
will not actually work.)
5. Once the key is displayed in Notepad, highlight the entire
key with your mouse. From the Edit menu, select Copy.
6. Switch back to the SSH Manager and paste the key into the
text box. You can do this by placing the cursor in the dialog
box and either selecting Edit and then Paste from your browsers
main menu or by using the key combination [Ctrl] + [V]. (Note:
the image below has been altered. It is not a real key.)
7. Select the Submit button. A new screen displays.
8. Enter the IP address for any computers from which you will
be accessing the server. You can get this information from your
ISP (Internet Service Provider). Or, if you are currently at
the computer you will be regularly using, you can find the IP
address by opening a DOS prompt and typing the command, ipconfig.
9. After you have entered a number in at least one of the spaces
provided, click on the Next button. A new screen displays.
10.Make sure that the IP address listed is correct. Then select
the Submit button. A message appears indicating that you will
be able to access the server, via your SSH software (Secure
CRT), from one of the addresses you listed within the next ten
minutes.
Once these steps have been performed, use the Secure CRT software
as usual to establish a connection to your site on the server.
You will be prompted for your passphrase when the connection
is made. Once the connection is made, Secure CRT works similarly
to other telnet utilities.
