See the documentation for your CLI client. On your management computer, start PuTTY. Type the packet capture command, such as:. A dialog appears where you can configure PuTTY to save output to a plain text file. In Session logging , select Printable output. You do not need to save it with the.
Click Apply. Close the PuTTY window. Open the packet capture file using a plain text editor such as Notepad. Delete the first and last lines, which look like this:. These lines are a PuTTY timestamp and a command prompt, which are not part of the packet capture. If you do not delete them, they could interfere with the script in the next step. Convert the plain text file to a format recognizable by your network protocol analyzer application. You can convert the plain text file to a format.
To download fgt2eth. The fgt2eth. To use fgt2eth. Methods to open a command prompt vary by operating system. On Windows 7, click the Start Windows logo menu to open it, then enter cmd. Open the converted file in your network protocol analyzer application. When troubleshooting networks and routing in particular, it helps to look inside the headers of packets to determine if they are traveling along the expected route.
Packet sniffing can also be called a network tap, packet capture, or logic analyzing. W h a t can sniffing packets tell you. If you are running a constant traffic application such as ping, packet sniffing can tell you if the traffic is reaching the destination, what the port of entry is on the FortiGate unit, if the ARP resolution is correct, and if the traffic is being sent back to the source as expected.
Note that RPF can be disabled by turning on asymmetric routing in the CLI config system setting, set asymetric enable , however this will disable stateful inspection on the FortiGate unit and cause many features to be turned off. If you configure virtual IP addresses on your FortiGate unit, it will use those addresses in preference to the physical IP addresses. You will notice this when you are sniffing packets because all the traffic will be using the virtual IP addresses.
What to look for in the information the sniffer reads. For a simple sniffing example, enter the CLI command diag sniffer packet port1 none 1 3. This will display the next three packets on the port1 interface using no filtering, and using verbose level 1. At this verbosity level you can see the source IP and port, the destination IP and port, action such as ack , and sequence numbers. With verbosity 4 and above, the sniffer trace will display the interface names where traffic enters or leaves the FortiGate unit.
When troubleshooting networks, it helps to look inside the header of the packets. This helps to determine if the packets, route, and destination are all what you expect. Packet capture can also be called a network tap, packet sniffing, or logic analyzing. Select the interface to monitor and select the number of packets to keep. Select E n a b l e Filters.
Enter the information you want to gather from the packet capture. To run the capture, select the p l a y button in the progress column in the packet capture list. If not active, N o t Running will also appear in the column cell. The progress bar will indicate the status of the capture. You can stop and restart it at any time. When the capture is complete, click the D o w n l o a d icon to save the packet capture file to your hard disk for further analysis. Packet capture tells you what is happening on the network at a low level.
This can be very useful for troubleshooting problems, such as:. If you are running a constant traffic application such as ping, packet capture can tell you if the traffic is reaching the destination, how the port enters and exits the FortiGate unit, if the ARP resolution is correct, and if the traffic is returning to the source as expected. You can also use packet switching to verify that NAT or other configuration is translating addresses or routing traffic the way that you want it to. Before you start capturing packets, you need to have a good idea of what you are looking for.
Capture is used to confirm or deny your ideas about what is happening on the network. If you try capture without a plan to narrow your search, you could end up with too much data to effectively analyze. On the other hand, you need to capture enough packets to really understand all of the patterns and behavior that you are looking for.
