Upgrade Software
From time to time, Cobalt Networks, Inc. issues updates to critical software that
runs on its products. Updates can be obtained from the Cobalt Networks Web
page (http://www.cobalt.com). Updates come in the form of a “package” file with
a “.pkg” file name suffix. The Update Software screen allows you to install new
packages on the CacheRaQ 4; see Figure 27.
Installing a package file
To install a package file:
1. Obtain the .pkg file from the Cobalt Networks Web site at
http://www.cobalt.com/support/download/index.html.
2. Save the .pkg file on the computer on which you run your Web browser.
3. On the CacheRaQ 4 UI, click Maintenance on the left. The Administrator
Settings table appears.
4. Click Upgrade Software at the top. The Upgrade Software and Software on
the Cobalt CacheRaQ 4 tables appear.
5. The Upgrade Software table offers three options for selecting a file.
a. To install a .pkg file referenced by a URL, enter the URL into the
URL field.
b. To upload a .pkg file from your computer, enter the path and file name or
click Browse... to search for the file on our computer.
c. The admin user can also use FTP to upload packages to the directory
/home/packages and then install them using the Loaded: option.
To do so, the admin must first telnet in to the CacheRaQ 4 and then FTP
out to get the package file. By default, you cannot FTP in to the
CacheRaQ 4.
6. Enter the admin password and click Install a ‘.pkg’ Package. The admin
password is required as a security precaution.
