Chapter 2. Requirements
9
If the RHN Proxy Server is configured to distribute custom, or local packages, make sure
that the
/var
mount point on the system storing local packages has sufficient disk space
to hold all of the custom packages, which are stored in
/var/spool/rhn-proxy
. The
required disk space for local packages depends on the number of custom packages served.
2.4. Additional Requirements
The following additional requirements must be met before the RHN Proxy Server installa-
tion can be considered complete:
Full Access
Client systems need full network access to the RHN Proxy Server services and ports.
Firewall Rules
The RHN Proxy Server solution can be firewalled from the Internet, but it must be
able to issue outbound connections to the Internet on ports 80 and 443. In addition,
if the Proxy will be connected to an RHN Satellite Server that will be configured to
push actions to client systems and the Proxy, you must allow inbound connections on
port 5222.
Synchronized System Times
There is great time sensitivity when connecting to a Web server running SSL (Se-
cure Sockets Layer); it is imperative the time settings on the clients and server are
reasonably close together so the that SSL certificate does not expire before or during
use. It is recommended that Network Time Protocol (NTP) be used to synchronize the
clocks.
Fully Qualified Domain Name (FQDN)
The system upon which the RHN Proxy Server will be installed must resolve its own
FQDN properly.
A Red Hat Network Account
Customers who will be connecting to the central Red Hat Network Servers to receive
incremental updates must have a Red Hat Network account. The sales representative
assists with the setup of this account at the time of purchase.
Backups of Login Information
It is imperative that customers keep track of all primary login information. For RHN
Proxy Server, this includes usernames and passwords for the Organization Adminis-
trator account and SSL certificate generation. Red Hat strongly recommends this in-
formation be copied onto two separate floppy disks, printed out on paper, and stored
in a fireproof safe.
