Setting rolling packet capture with increased size limit on ProxySG

Products

• Advanced Secure Gateway Software - ASG
• ProxySG Software - SGOS

Issue/Introduction

As of SGOS 6.5.2.1, a packet capture can be set to exceed the previous hard coded maximum capacity of 100MB. Now, it will allow a capture up to 3% of the available system memory at startup (not to exceed 4GB). The default packet capture file size is still 100MB. Increasing the capacity of the capture file is done manually each time and cannot be set to automatically capture more than the default for future captures. The following instructions will show how to increase the maximum capacity of the packet capture file.

 

Resolution

1. In the ProxySG management console, go to Maintenance>Service Information>Packet Captures, and click the Start Capture button.
2. In the Start Capture dialog box, select the radio button for Capture last ____ matching KBytes and enter the value of 4000000 in the empty field. 
3. Click the Start Capture button.

   



Note: An expected error window will display. This message will let you know the maximum packet capture file size the ProxySG will accept. 

   

 

Use the maximum value of the capsize you received in the error if wanting to obtain the largest packet capture file possible. Otherwise, enter a lesser value as needed. 

After closing the error message dialog box, start over.

Follow steps 1 - 3 again but this time on step 2, enter a value no greater than the max capsize value you received in the error. 

Note: If you would like the capture to NOT be a rolling capture, but just have an increased size, you can choose the option in the above image showing Capture first _________ matching Kbytes in step 2.
