Chapter 7. Troubleshooting
55
The following measures can be used to troubleshoot general connection errors:
•
Attempt to connect to the RHN Satellite Server’s database at the command line using
the correct connection string as found in
/etc/rhn/rhn.conf
:
sqlplus
username/password@sid
•
Ensure the RHN Satellite Server is using Network Time Protocol (NTP) and set to the
appropriate time zone. This also applies to all client systems and the separate database
machine in RHN Satellite Server with Stand-Alone Database.
•
Confirm the correct package:
rhn-org-httpd-ssl-key-pair-
MACHINE_NAME-VER-REL
.noarch.rpm
is
installed
on
the
RHN
Satellite
Server
and
the
corresponding
rhn-org-trusted-ssl-cert-*.noarch.rpm
or raw CA SSL public (client)
certificate is installed on all client systems.
•
Verify the client systems are configured to use the appropriate certificate.
•
If also using one or more RHN Proxy Servers, ensure each Proxy’s SSL certificates are
prepared correctly. The Proxy should have both its own server SSL key-pair and CA SSL
public (client) certificate installed, since it will serve in both capacities. Refer to the SSL
Certificates chapter of the
RHN Client Configuration Guide
for specific instructions.
•
Make sure client systems are not using firewalls of their own, blocking required ports as
identified in Section 2.4

7.5. Satellite Debugging by Red Hat
If you’ve exhausted these troubleshooting steps or want to defer them to Red Hat Network
professionals, Red Hat recommends you take advantage of the strong support that comes
with RHN Satellite Server. The most efficient way to do this is to aggregate your Satellite’s
configuration parameters, log files, and database information and send this package directly
to Red Hat.
RHN provides a command line tool explicitly for this purpose: The
Satellite Diagnostic
Info Gatherer
, commonly known by its command
satellite-debug
. To use this tool,
issue the command as root. You will see the pieces of information collected and the single
tarball created, like so:
[root@miab root]# satellite-debug
Collecting and packaging relevant diagnostic information.
Warning: this may take some time...
* copying configuration information
* copying logs
* querying RPM database (versioning of RHN Satellite, etc.)
* querying schema version and database character sets
* get diskspace available
* timestamping
