So i just registered today on this awesome forum. Hoping to gain knowledge and learn from people about hacking from this forum. so i have some questions (Its nub questions)

1)What is Dns and Dns spoofing?

2)What is a Default Gateway and what is a Subnet mask?

3)What is a Port?
4)When i use Nmap in Kali Linux sometimes when i scan Ips it shows all ports are filtered what does that mean?

5)So when i open My Slowloris dos Program what should i set the -timeout to be? 1 second or 100 seconds

Okay that's all of my Questions sorry if am really noobish

thanks in advanced.

For 1 and 2 put the words in Google and read what comes up.

For 3, so the same for the words "network port".

For 4, do the same for the words "filtered port".

For 5, read up on what slowloris does (again, Google knows all and Wikipedia elaborates). Given what the program is intended to do you should be able to understand what a good value is.

My advice to you: Read this pinned topic on where to begin with hacking because trying to DDoS a machine without even knowing what a network port is sounds a lot like wanting to partake in the Tour The France before learning to crawl.

1 DNS is like the phone-book of the internet... google is the website name (www.google.com) but it also has an ip which you can get by using a command like ping...

DNS spoofing is tricking a computer to go to the wrong ip (and therefore the wrong website)

2 Default gateway is the internal ip of your router... the subnet mask is the way the network is split... home networks would have lots of available subnets but few hosts (255.255.255.0) link with more detail :https://www.youtube.com/watch?v=EkNq4TrHP_U

3 Ports are (if open) sort of open doors where information can flow between computers. The "traditional internet" (http) is on port 80 and the "secure internet" (https) is on port 443

4 Filtered ports send a signal back that U SHALL NOT PASS and closed ports don't answer.

5 Dos'ing a machine is almost imposible with only one computer, look in to DDos'sing (basically Dos'ing with more machines). The more fun stuff is mitm (man in the middle), just look this one up on youtube... good tools include bettercap ettercap mitmf and ofc. the wifi pineapple. But check if you are allowed to do it on the network you are on...
