[Bug]: how to open port

[lzhphantom]

Problem description

I run qemu-system-x86_64 -hda alpine.img -boot c -m 6144 -smp 3 -netdev user,id=nde1,hostfwd=tcp::2222-:22,hostfwd=tcp::8848-:8848,hostfwd=tcp::3306-:3306 -device e1000,netdev=nde1,id=d-net1 --vnc :1, namp only scan 80,2222,3306,5901,8022, the 8848 port is missing.

Steps to reproduce the behavior.

alpine.img set 50G
running qemu-system-x86_64 -hda alpine.img -boot c -m 6144 -smp 3 -netdev user,id=nde1,hostfwd=tcp::2222-:22,hostfwd=tcp::8848-:8848,hostfwd=tcp::3306-:3306 -device e1000,netdev=nde1,id=d-net1 --vnc :1
run nmap 127.0.0.1

What is the expected behavior?

how to make 8848 port, can be scan out

Try explicitly set port range for nmap scanning.

nmap -p 1-10000 127.0.0.1

By default nmap scans only common ports (https://nmap.org/book/man-port-specification.html).

There's nothing wrong in your qemu command.
