Appendix F: Basic Troubleshooting Troubleshooting proxy rules 658 cf acl set loglevel=4 This increases the level of rule audits from the default level 2 (minor) to level 4 (major). Note: Modifications to the log level setting will not be overwritten if acld is restarted. To return the log level to its default value, you must manually reset it. When the connection attempt is rejected, the proxy or server will generate a more verbose audit message as shown below: May 5 02:37:42 2002 CDT f_ping_proxy a_aclquery t_info p_major pid: 184 ruid: 0 euid: 0 pgid: 184 fid: 2000001 logid: 0 cmd: 'pingp' domain: Ping edomain: Ping +|pingp|INFO|MAJOR|PING_PROXY|aclQUERY =Skipped 'http_out': query service 'ping' != rule 'http'.

Skipped 'telnet_out': query service 'ping' != rule 'telnet'. Skipped 'nntp_out': query service 'ping' != rule 'nntp'. Skipped 'real_media_out': query service 'ping' != rule 'RealMedia'.

Skipped 'cobra_all': query agent 'proxy' != rule 'server'. Skipped 'login_console': query agent 'proxy' != rule 'server'. Access denied by rule 'deny_all'. You can use this output to determine why each proxy rule failed to match the connection request. Locate the proxy rule that you thought should have matched. Then inspect and correct the proxy rule. 6 When you are done troubleshooting, type the following command to lower the level of rule audits back to the default: cf acl set loglevel=2
Appendix F: Basic Troubleshooting Troubleshooting proxy rules If you do not set the loglevel back to 2, you will run out of disk space. Monitoring allow and deny rule audit events Another troubleshooting tool is the rule monitoring tool (acat_acls). This real time monitoring tool enables you to display allow and deny rule audit events as they occur on the Sidewinder G2. Because the rule audit events are displayed in real time, this tool provides a Sidewinder G2 administrator a unique window by which to view Sidewinder G2 rule activity. You can use the tool to determine if your rule database is properly configured, or to simply view how your rules are being used on a live system. For example: • If you are not certain whether your Telnet rule is properly configured, you can start the monitoring tool, attempt your Telnet connection and see (in real time) whether the connection is allowed or denied. • If you want to see (in real time) which rules are currently the most heavily used, start the monitoring tool and watch as the current rule audit events scroll by within a command window. The remainder of this section provides information on using the monitoring tool. Information can also be found by typing man acat_acls at a Sidewinder G2 command prompt. Starting the rule monitoring tool (acat_acls) To start the rule monitoring tool, enter the following commands at a Sidewinder G2 command prompt: srole /usr/bin/acat_acls -a -d where: • -a = display allow rule audit events • -d = display deny rule audit events If you want to view only allow rule audit events or only deny rule audit events, simply omit the undesired option (-a or -d). 659
