I've changed the DNS name setting of my Proxy Server, and now my client systems
can't update. How can I fix t his?
Run the up2date -u command on the client system for the name change to take effect.
How can I determine whether the client s are connecting to the Squid server?
The /var/log/squid/access.log file logs all connections to the Squid server.
The Red Hat Update Agent on the client systems does not connect through the RHN
Proxy Server. How can I resolve this error?
Make sure that the latest version of the Red Hat Update Agent is installed on the client systems.
The latest version contains features necessary to connect through an RHN Proxy Server. The
latest version can be obtained through the Red Hat Network by issuing the command yum
update yum as root or from http://www.redhat.com/support/errata/.
The RHN Proxy Server is an extension of Apache. See T able 6.1, “Log Files” for its log file location.
My RHN Proxy Server configuration does not work. Where do I begin troubleshooting it?
Make sure /etc/sysconfig/rhn/systemid is owned by root.apache with the permissions
0640.
Read the log files. A list is available at T able 6.1, “Log Files”.
6.4. General Problems
To begin troubleshooting general problems, examine the log file or files related to the component
exhibiting failures. A useful exercise is to tail all log files and then run up2date --list. You should
then examine all new log entries for potential clues.
A common issue is full disk space. An almost sure sign of this is the appearance of halted writing in the
log files. If logging stops during a write, such as mid-word, you likely have filled disks. T o confirm this, run
this command and check the percentages in the Use% column:
df -h
In addition to log files, you can obtain valuable information by retrieving the status of your various
components. T his can be done for the Apache Web server and Squid.
To obtain the status of the Apache Web server, run the command:
servi ce httpd status
To obtain the status of Squid, run the command:
servi ce squid status
If the administrator is not getting email from the RHN Proxy Server, confirm the correct email addresses
