How do you know if an DDoS attack is happening?

Not all disruptions to service are the result of a denial-of-service attack. There may be technical problems with a particular network, or system administrators may be performing maintenance. However, the following symptoms could indicate a DoS or DDoS attack:

* unusually slow network performance (opening files or accessing websites)
* unavailability of a particular website.
* inability to access any website.
* dramatic increase in the amount of spam you receive in your account.

DDOS attack

DDOS attack: Find the domains which are under attack.

If your cpanel server is under DDOS attack then just go to the directory /usr/local/apache/domlogs and then use the command:

grep ‘408 -’ *.com > output_file_name

You can use the search pattern for any other domains with the extension .net .org etc.
