Thank you for reaching out @claudiociardelli,
i think it should come from your firewall. What does return
$ nmap -T4 -sT 192.168.1.70
?
Also what is the operating system of your server?
Or it may come from an actual bug, that https://github.com/skerkour/kerkour.com/commit/f1ea1ea6f6996b3ccc99fbeee4106523b10db7e4 should have fixed.
Could you tell me if the result is similar with the new version
NAME="Ubuntu" VERSION="20.04.3 LTS (Focal Fossa)"
I applied the fix, but still not returning all ports. Nmap tells me this
~/projects/kerkour.com/2021/rust_fast_port_scanner$ nmap -T4 -sT 192.168.1.70 Starting Nmap 7.80 ( https://nmap.org ) at 2021-10-16 20:31 UTC Nmap scan report for dev01 (192.168.1.70) Host is up (0.00013s latency). Not shown: 998 closed ports PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp Nmap done: 1 IP address (1 host up) scanned in 0.25 seconds
Thanks for the feedback.
What does return https://github.com/skerkour/black-hat-rust/tree/main/ch_02/tricoder

Sylvain, tricorder and rust_fast_port_scan now work correcty. I wonder if I had not retested correctly yesterday after refreshing my local repository. Thx for your help
I'm glad to hear that :)
Have a nice day
Hello @claudiociardelli , I tested rust_fast_port_scanner today. Not sure if this is an issue or a lack of understanding from me: I run the program with the IP address of my linux server to check what ports might be listening to requests. so I ran the command like this:
I will not print the result here, But I get 1002 rows in the result so, all the ports tested. From @claudiociardelli (https://github.com/skerkour/bloom/issues/72)
However when I check what ports are listening as per https://www.techrepublic.com/article/how-to-locate-and-close-an-open-port-in-linux/ I only see 6 open ports
