Frequently Asked Questions 71
Q: Can I use Red Hat Network to upgrade my Red Hat Linux kernel?
A: Yes. You must use
Red Hat Update Agent
version 2.5.4 or higher. If you choose the kernel
packages and allow Red Hat Network to install them to your system, it will modify your LILO config-
uration file so that your system boots the new kernel the next time it is rebooted. If you just download
the RPM packages and install them yourself, you will need to modify LILO to boot the new kernel.
Q: Why does the
Red Hat Update Agent
return the error "No Route to Host"?
A: The system you are running it on is not connected to the Internet, or the system is attempting to
access Red Hat Network through a proxy server. Proxy server settings can be configured in the newest
version of
up2date
available at http://www.redhat.com/support/errata/RHBA-2000-138.html. For
instructions on configuring the proxy server, refer to Section 3.2, General Settings.
Q: Why does the Red Hat Network Registration Client return the error "No Route to Host"?
A: The system you are running the
Red Hat Network Registration Client
(
rhn_register
) on
is not connected to the Internet, or the system is attempting to access Red Hat Network through a
proxy server. Proxy server settings can be configured in the newest version of rhn_register available
at http://www.redhat.com/support/errata/RHBA-2000-138.html. For instructions on configuring the
proxy server, refer to Section 2.1, Configuring the
Red Hat Network Registration Client
