Debugging Proxy

A few pointers for issues you might run into with Proxy:

Useful log files:

• /var/log/httpd/* - Apache logs
• /var/log/squid/* - Squid logs
• /var/log/rhn/rhn_proxy_broker.log - Proxy Broker Server
• /var/log/rhn/rhn_proxy_redirect.log - SSL Redirect Server

Config files:

• /etc/httpd/conf.d/*.conf
• /etc/rhn/rhn.conf
• /etc/squid/squid.conf
• /etc/sysconfig/rhn/up2date

You can raise the debug level in /etc/rhn/rhn.conf to increase logging to the Proxy Broker and SSL Redirect logs - set to a value between 0 (default) and 9 (loads of debugging info).

Common Errors

When starting up Squid: "Aborted $SQUID $SQUID_OPTS >>/var/log/squid/squid.out FATAL: Could not determine fully qualified hostname"

Set visible_hostname in /etc/squid/squid.conf - see [[https://access.redhat.com/articles/10825]]

If after running configure-proxy.sh your clients receive a "Spacewalk Proxy service not enabled for server profile: 'proxy_fqdn' Error Class Code: 1002", try rerunning rhn-proxy-activate as below, then verify that the systemid of your new proxy server as specified in /etc/sysconfig/rhn/systemid matches the row in rhnproxyinfo in your database:

rhn-proxy-activate --server=<fqdn-of-your-master-here>


[you@asatproxyserver ~]# grep ID- /etc/sysconfig/rhn/systemid 
<value><string>ID-1000036838</string></value>
[you@asatmasterserver ~]# spacewalk-sql -i
psql (8.4.20)
