Q: What is the difference between the Red Hat Update Agent and the Red Hat Network Web
Application?
A: Both allow you to retrieve the latest software packages for a registered system from RHN. However,
the Red Hat Network Web Application allows you to manage more than one registered system at
the same time through a Web interface and is more customizable.
Q: Why is something called rhnsd running on my system and what does it do?
A: rhnsd is the Red Hat Network Daemon. Every thirty minutes, it sends a request to Red Hat Net-
work asking for any notifications or updates and works in coordination with the Red Hat Network
Web Application to schedule automated tasks. It only sends information to Red Hat Network re-
quested by you. If you add a new system using the Red Hat Network Web Application, the next
time the Red Hat Network Daemon probes Red Hat Network it receives a request to return the infor-
mation you requested as part of your System Profile such as what package versions are installed on
your system.
