Really appreciate these Go tutorials. Good Go content is hard to come by.

i tired making a good port scanner in rust since im building an AI and was going o add a thing where you can say a target and port scan it but sadly there wasnt any good tutorials for it so your channel and vid cam up. i followed along and i have to say amazing work man, this saved me probobly a good week trying to find a good tutorial! keep doing what your doing man

This was great. Have to try this with goroutines to do the checks asynchronously

Thanks for making these

This is Awesome. Thanks man.

Hey, great video! I've just got a note about the bit at the end. I don't think the UDP part of this code will provide useful results - with TCP, the connection is successful when you send a packet and get an acknowledgement in response; with UDP, the connection is considered successful if you just send the packet (regardless of if anyone actually receives it). Notice that the UDP scan results report all ports as open.

Keep rocking buddy

Hi, what IDE are you using in this tutorial?

Hey, What is that font?

Hello bro! How can I get the body (JSON, plain text,...) of a request from the packets I've got?

Black hat go?;) I subbed btw!

performance can be improved using go routines

Why are all the udp opened?

Github repo doesnt work /gone

All tcp closed all udp opened

amazing how you dont use go routines

Great tutorial thanks :) I tried adding goroutines: the scan becomes almost immediate. func InitialScan(hostname string) []ScanResult { var results []ScanResult wg := sync.WaitGroup{} for i := 1; i < 1024; i++ { wg.Add(1) go func(port int) { fmt.Printf("Go routine created for port %v ", port) results = append(results, ScanPort("tcp", hostname, port)) results = append(results, ScanPort("udp", hostname, port)) fmt.Printf("Go routine %v done ", port) wg.Done() }(i) } wg.Wait() return results } Way faster but the results are displayed in a random order :)
