Removing Fortigate Reminders on Login to Dashboard

When logging into Fortigate, certain operations are checked and a reminder window has to be passed before you get to the dashboard. For example you will definetly have this window show up after a firmware upgrade. If you have the actions planned for a later date do not want to get the reminder window here's how.

config system global

set gui-forticare-registration-setup-warning disable

set gui-firmware-upgrade-warning disable 

end 

 

 

          

Packet Capture / Sniffer setup on a Fortigate without a disk

Here's how I go about to capture packets in a Fortigate Firewall which does not have a disk.

1. Use a good SSH Client that can log the session, such as putty. And setup the log session to file feature.
This will than allow me to get the capture output as a text file and run through the utility that converts it to a pcap file.

2. Setup the sniffer on Fortigate:

diagnose sniffer packet <interface_name> <‘filter’> <verbose> <count> <tsformat>

For example:

diagnose sniffer packet any "host <src_host_ip> and host <dst_host_ip>" 6

(verbose=6 gives interface names to the output, we'll get as much info as we need, thus the maximum level of verboseness)

 

3. Cleanup the text file and run it through the conversion utility.

Fortinet utility (there's linux perl and windows exe version here)

Usage: 

fgt2eth.exe -in <file captured>.txt -out <output name>.cap

 

Alternatives which I haven't test yet:

fgsniffer (announcement post on fortinet forums)

sniftran 

4. Open the converted pcap file in Wireshark.

5. Get a dark coffee and dive deep into the capture! :)
