Basic Connections and Configuration 75
and fingerprints for the GigaVUE node. Paste these in a file and keep them
nearby when you connect via SSH2 the first time. This way, you’ll be able to
compare the actual host key to what your SSH2 client says is being
presented. Once you’ve verified that they are the same, you can choose to
trust the host key, allowing future connections to take place seamlessly.
Changing Host Keys
You can use the ssh server host-key generate command to change the
default host keys provided with the GigaVUE TA Series node. The command
has the following syntax:
ssh server host-key <rsa1 | rsa2 |dsa2> <private-key | public-key> generate
For example, to configure a new RSAv1 public hostkey, you could use the
following command:
(config) # ssh server host-key rsa1 public-key generate
Initial User Account Configuration
Before you start mapping traffic, you must change the password for the
admin account and add a few other accounts for use by different level users.
(You may have already used the jump-start script to change the password for
the
admin account.)
Changing the admin Account Password
1.
To change the password for the admin account using the username
command, refer to the following:
(config) # username admin password <password>
Passwords must meet the following standards:
•
Include 8-30 characters.
•
Include at least one numeral
•
Include at least one capital letter
•
Include at least one special character (for example, ! , @ , # , $ , % , ^ , & ,
or * – ASCII [0x21, 0x2F], [0x3A, 0x40], [0x5B, 0x5F], [0x7B,0x7E]).
Enter a new password that meets the standards and confirm the
password.
Setting Up Some Basic Accounts
The TA Series node has a local account database that can optionally
integrate with an LDAP, RADIUS, or server for authentication. Any
account you want to authenticate using an external AAA server must have a
matching account name in the local database.
Authentication, user levels, and roles are discussed in detail in the
GigaVUE-OS CLI User’s Guide . For now, however, it is easiest to simply
