The netdump-server package is not shipped with Red Hat Enterprise Linux 5. Netdump has been replaced by Kdump (see How do I configure kexec/kdump on Red Hat Enterprise Linux 5? for information on configuring Kdump).

If you need to continue using Netdump with Red Hat Enterprise Linux 5 to support older clients, there are two options:

1. Set up a Red Hat Enterprise Linux 4 Virtual Guest on a Red Hat Enterprise Linux 5 machine and configure it as netdump server.

2. Install the Netdump packages from the EPEL program on your Enterprise Linux 5 machine. See How do I use Extra Packages for Enterprise Linux (EPEL)? for information about EPEL and how to use it.

This error can occur if the system is only registered to the base channel (Eg: Red Hat Enterprise Linux (v. 5 for 32-bit x86) and not the Virtualization channel in Red Hat Network (RHN). The virtualization packages are only available in the "Red Hat Enterprise Linux Virtualization" channel and not the base channel.

To resolve this, preform the following steps"

1. Login to Red Hat Network

2. Select Systems tab.

3. Click on the appropriate system

4. Click on the link "Alter Channel Subscriptions".

5. Add the child channel "Red Hat Enterprise LinuxVirtualization" (Eg: Red Hat Enterprise Linux Virtualization (v. 5 for 32-bit x86)

6. Save and rerun the yum command that failed.

Note: Another cause for this error could be a problem with the Yum metadata cache. See Why do I get "Error: Missing Dependency:" messages from Yum when updating packages on Red Hat Enterprise Linux 5? for more details.
