Fortianalyzer with gmail setup

If you tried to setup Fortianalyzer sending alert via gmail but kept fail

p/s  if you tried setup with 3th party apps for send notification via gmail, this guide might suit too.

Current my analyzer running 5.2.5

Herewith the steps

1. Setup on Fortianalyzer mail server setup



for information about gmail setting
https://support.google.com/a/answer/176600?hl=en


2. SSH to Fortianalyzer , configure the secure option, this command make sure using starttls.

Example

config system mail
    edit "Gmail"
        set secure-option starttls
   next
end

below is the wireshark capture  using starttls, as the red arrow indicate the SSL handshake start


3. Login into your gmail account

4. Access the url https://www.google.com/settings/security/lesssecureapps , turn it on



You can skip steps 5 and 6 if you 1st time setup gmail smtp server, else continue

5. Access the url https://accounts.google.com/DisplayUnlockCaptcha, click continue


6. You will come to this page below



6. Let test the email setup, right click the email setup and key in the recipient email


7. You should successfully send the email

CAUTION : reload stack switch

最阴Cisco :D


Sometimes habit/dependent lead to mistakes.

When reload 2960x stack switch (maybe apply to all stack switch), you might reload entire stack

Sometimes is too confident when execute command but shit happen



Normally reload member by execute reload slot x, 

So, when execute reload , less/missing 1 alphabet (reload slo 1) ; it still working fine, reload the member switch 




But when execute reload, example
reload slor 2 !! It should prompt error as usual, but this time cisco prompt confirm, so just press enter ; 
Surprise !!!


It reload entire stack switch
 




What if the switch is in production and design as below


At that moment,

Engineer



5 min downtime is not fun at all , my career is on chopping board or ban access to customer data center

Customer might lost  million dollars (trading) , or someone lost his life (if Hospital failed to authenticate patient medical card and missed the golden rescue period)

Lucky was in post migration environment

So, I posted something in community
herewith my post at Cisco community

https://supportforums.cisco.com/discussion/12732176/2960x-reload-command-issue


community member post it proper document about reload command, Cisco treat it as reason when execute wrong command LOL

herewith document 

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960x/software/15-0_2_EX/stack_manager/command_reference/b_stck_152ex_2960-x_cr/b_stck_152ex_2960-x_cr_chapter_01.html#wp3486313748


But I look at it as defect coding. Confusing engineers/administrator and mislead engineer.


Although it proper document but doesn't make sense to me or any engineer because  used to it prompt error when execute wrong command, sadly in this case it doesn't 

Be caution when reload stack switches


Thanks
