Basic GigaVUE H Series Connections and Configuration 103
Verifying Host Keys During Connection
To verify that the host key presented during an SSH2 connection is in fact the GigaVUE
node’s, you can connect over the console port (refer to
Access the Command-Line
Interface over the Console Port on page 37 ) and use the show ssh server host-keys
command to see the current public host keys and fingerprints for the GigaVUE-HC3.
Paste these in a file and keep them nearby when you connect via SSH2 the first time.
This way, you will be able to compare the actual host key to what your SSH2 client says
is being presented. Once you have verified that they are the same, you can choose to
trust the host key, allowing future connections to take place seamlessly.
Changing Host Keys
Use the ssh server host-key generate command to change the default host keys
provided with the GigaVUE-HC3. 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
Enabling the GigaVUE H Series Web Server
GigaVUE-FM is Gigamon’s Web-based management interface for the GigaVUE
H Series. Use GigaVUE-FM for many node configuration, management, and
operations tasks.
To use GigaVUE-FM with a GigaVUE H Series node, you must enable its Web server
with the
web enable command. For example:
(config) # web enable
Check the status of the Web server using the show web command. Make sure that
Web-based management console enabled: is set to yes , indicating that the Web
server is enabled. For example:
Once the Web server is enabled, you can use GigaVUE-FM for GigaVUE H Series
connections, as described in
Connecting to the GigaVUE H Series Node from
GigaVUE-FM on page 104 . Refer to the GigaVUE-OS CLI Reference Guide for
information on other Web server settings you can configure.
