Manual diagnostic tests

The Manual tab offers 4 commands typically run from the Linux command line.

Ping, used to determine if a remote device can be reached across the network.

Traceroute, used to determine the path network packets take and measure delays across the network.

NSlookup, used to obtain domain name or IP address mapping.

TCPDump, used to analyze network packets.

Click the radio button next to the command you want to execute and enter parameters for the command in the entry field provided.

Enter a server name or IP address for Ping or Traceroute.

Enter a server name for NSlookup.

Enter valid parameters for TCPDump. Click the link provided for additional information on using TCPDump with Content Gateway. View the same technical article using this link.

Click the Run button next to your selected command to execute the test. The results for Ping, Traceroute, and NSlookup display in the Test Results section at the bottom of the pane.

Test results for TCPDump are typically too long to easily display and review in the Test Results window. When TCPDump is run, the Test Results window simply indicates the success or failure of the command.

As TCPDump runs, output is written to /opt/WCG/logs/tcpdump.pcap. This file is overwritten each time TCPDump is executed. When a test is successful, a link is provided so that you can download and view or save a copy of the most recent file.

To avoid disk space problems, tcpdump.pcap is limited to 10,000 packets. Once that limit is reached, no additional output is written to the file.


	Important TCPDump uses a lot of system resources. Try to avoid using it during peak hours when the system is busy.

As each command executes, the Run button becomes a Stop button. Click Stop to abort the command.
