Veritas Access Troubleshooting Guide

To use the tethereal command

• To use the Support> tethereal export command, enter the following:

  Support> tethereal export url [nodename] [interface] [count] 
  [source]

  url	Provides the location to export the network traffic details. The default file name tethereal.log is used if a file name is not specified in the url.
  nodename	The name of the node from where the traffic details are generated.
  interface	Specifies the network interface for the packet capture.
  count	Specifies the maximum number of packets to read. The maximum allowed file size to capture the network traffic details is 128 MB. For a very large "count" value, if the file size exceeds 128 MB, then the command stops capturing the network traffic details.
  source	Specifies the node to filter the packets.

  For example, to export the network traffic details, enter the following:

  Support> tethereal export scp://user1@172.31.168.140:˜/
  Password: *******
  Capturing on pubeth0 ...
  Uploading network traffic details to scp://user1@172.31.168.140:˜/ 
  is completed.

  When you export network traffic details, press the Ctrl + C keys to stop the capture process and upload traffic details to the URL site.

To use the tethereal show command

• To use the Support> tethereal show command, enter the following:

  Support> tethereal show [nodename] [interface] [count] 
  [source]

  nodename	The name of the node from where the traffic details are displayed.
  interface	Specifies the network interface for the packet capture.
  count	Specifies the maximum number of packets to read. If you do not specify a count value, the network traffic continues to be displayed until you interrupt it.
  source	Specifies the node to filter the packets.

  For example, the traffic details for five packets are:

  Support> tethereal show access_01 pubeth0 5 172.31.168.140
  0.000000 172.31.168.140 -> 10.209.105.147 ICMP Echo (ping) request
  0.000276 10.209.105.147 -> 172.31.168.140 ICMP Echo (ping) reply
  0.000473 10.209.105.147 -> 172.31.168.140 SSH Encrypted response 
  packet len=112
  0.000492 10.209.105.147 -> 172.31.168.140 SSH Encrypted response 
  packet len=112
