Configuring general host settings
You view and modify general host settings in the Administration > Networking: Host Settings page.
The Host Settings page isn’t controlled by the SCC Network role but by the SCC General Settings role. The Host Settings page accepts IPv4 and IPv6 addresses.
When you initially run the installation wizard, you set required network host settings for the SCC. Use these groups of controls on this page only if you require modifications, additional configuration, or want to verify the DNS configuration:
•  Name - Modify the hostname only if your deployment requires it.
•  DNS Settings - We recommend you use DNS resolution.
•  Hosts - If you don’t use DNS resolution, or if the host doesn’t have a DNS entry, you can create a host-IP address resolution map.
•  Configure How this Appliance Connects to the Network - Configure proxy addresses for web or FTP proxy access to the SteelHead. You can also create a whitelist of domains allowed to bypass the proxy. Because SteelHead backups to SCC are blocked if a proxy is enabled, this option lets you enter an exception to allow direct SteelHead to SCC communication.
Changing the hostname from IPv4 to IPv6
The SCC uses the SSH and HTTPS to communicate with appliances. The SSH connection is initiated from SCC and merely changing the SCC hostname from the SteelHead will not disconnect and reinitiate the SSH connection.
Explicitly breaking SSH/HTTPS channels
You must explicitly break the SSH and HTTPS channels on the SCC. You can break the channels in any one of these ways:
•  The IPv4 channel can be broken by disabling the IPv4 address from the Interface.
•  The IPv6 channel can be broken by disabling the IPv6 address from the Interface.
•  Rebooting the SCC.
Alternatively, you can also break the SSH/HTTPS channels by:
•  running the CLI command no scc enable on the SteelHead.
•  specifying the new IP address of SteelHead in the Manage > Appliances: Appliances Pages: Host Settings. For details about change the SteelHead appliance IP address in the SCC, see Managing host settings.
-or-
changing the IP address in SCC in the Host Settings page. For details, see To modify host settings.
This table summarizes the CLI steps to establish the SSH/HTTPS channels.
Appliance conditions
No SSH/HTTPS channels
There is SSH/HTTPS channel already over IPv4
There is SSH/HTTPS channel already over IPv6
SteelHead & SCC reachable over IPv4 and IPv6
To establish an SSH/HTTPS channels:
scc hostname <ip-address> scc enable
Until  the existing SSH/HTTPS channel is broken explicitly the IPv4 SSH/HTTPS channel will continue to  exist. Break the channels using the procedures described above.
To reestablish the SSH/HTTPS channels:
scc hostname <ip-address>
scc enable
Until  the existing SSH/HTTPS channel is broken explicitly the IPv6 SSH/HTTPS channel will continue to  exist. Break the channels using the procedures described above.
To reestablish the SSH/HTTPS channels:
scc hostname <ip-address>
scc enable
SteelHead & SCC reachable over IPv4 only
To establish the SSH/HTTPS channel over IPv4:
scc hostname <ip-address> scc enable
To establish the SSH/HTTPS channel over IPv4:
scc hostname <ip-address>
scc enable
Not applicable
SteelHead & SCC reachable over IPv6 only
To establish the SSH/HTTPS channel over IPv6:
scc hostname <ip-address> scc enable
Not applicable
To establish the SSH/HTTPS channel over IPv6:
scc hostname <ip-address>
scc enable
To change the hostname
1. Choose Administration > Networking: Host Settings to display the Host Settings page.
2. Under Name, modify the value in the Hostname field.
3. Click Apply to apply your changes to the running configuration.
4. Click Save to Disk to save you settings permanently.
To specify DNS settings
1. Choose Administration > Networking: Host Settings to display the Host Settings page.
2. Under DNS Settings, complete the configuration as described in this table.
Control
Description
Primary DNS Server
Specify the IP address for the primary name server. The IP address can be either IPv4 or IPv6. For IPv6 specify an IP address using this format: eight 16-bit hexadecimal strings separated by colons, 128-bits. For example:
2001:38dc:0052:0000:0000:e9a4:00c5:6282
You don’t need to include leading zeros. For example:
2001:38dc:52:0:0:e9a4:c5:6282
You can replace consecutive zero strings with double colons (::). For example:
2001:38dc:52::e9a4:c5:6282
Secondary DNS Server
Optionally, specify the IP address for the secondary name server.
Tertiary DNS Server
Optionally, specify the IP address for the tertiary name server.
DNS Domain List
Specify an ordered list of domain names.
If you specify domains, the system automatically finds the appropriate domain for each of the hosts that you specify in the system.
To modify host settings
This procedure is required when you want to override DNS-provided host information.
1. Choose Administration > Networking: Host Settings to display the Host Settings page.
2. Under Hosts, complete the configuration as described in this table.
Control
Description
Add a New Host
Displays the controls for adding a new host.
IP Address
Specify the IP address, either IPv4 or IPv6, for the host.
For IPv6 specify an IP address using this format: eight 16-bit hexadecimal strings separated by colons, 128-bits. For example:
2001:38dc:0052:0000:0000:e9a4:00c5:6282
You don’t need to include leading zeros. For example:
2001:38dc:52:0:0:e9a4:c5:6282
You can replace consecutive zero strings with double colons (::). For example:
2001:38dc:52::e9a4:c5:6282
Hostname
Specify a hostname.
Add
Adds the host.
Remove Selected
Select the check box next to the name and click Remove Selected.
Apply
Applies your settings to the running configuration.
3. Click Save to Disk to save your changes permanently.
To set a proxy
1. Choose Administration > Networking: Host Settings to display the Host Settings page.
2. Under Configure How this Appliance Connects to the Network, complete the configuration as described in this table.
Control
Description
Enable Proxy Settings
 
 
 
Provides network proxy access to the SteelHead. Enables the SteelHead to use a proxy to contact the Riverbed licensing portal and fetch licenses in a secure environment. You can optionally require user credentials to communicate with the proxy, and you can specify the method used to authenticate and negotiate user credentials.
Proxy access is disabled by default.
RiOS supports these proxies: Squid, Blue Coat Proxy SG, Microsoft WebSense, and McAfee Web Gateway.
Web/FTP Proxy
Specify the IP address, either IPv4 or IPv6, for the network or FTP proxy.
For IPv6 specify an IP address using this format: eight 16-bit hexadecimal strings separated by colons, 128-bits. For example:
2001:38dc:0052:0000:0000:e9a4:00c5:6282
You don’t need to include leading zeros. For example:
2001:38dc:52:0:0:e9a4:c5:6282
You can replace consecutive zero strings with double colons (::). For example:
2001:38dc:52::e9a4:c5:6282
Port
Optionally, specify the port for the network or FTP proxy. The default port is 1080.
Enable Authentication
Optionally, select to require user credentials for use with network or FTP proxy traffic. Specify these values to authenticate the users:
•  User Name - Specify a username.
•  Password - Specify a password.
•  Authentication Type - Select an authentication method from the drop-down list:
–  Basic - Authenticates user credentials by requesting a valid username and password. This is the default setting.
–  NTLM - Authenticates user credentials based on an authentication challenge and response.
–  Digest - Provides the same functionality as basic authentication; however, digest authentication improves security because the system sends the user credentials across the network as a Message Digest 5 (MD5) hash.
Proxy Whitelist
Optionally, add or remove domains from a proxy whitelist.
Apply
Applies your changes to the running configuration.
