我在 ubuntu 上启动 samba 时遇到困难

我如何查看我的机器上打开了哪些端口？

root@ubuntu-s-1vcpu-1gb-intel-nyc1-01:~# sudo netstat -ntlp | grep LISTEN

(added lines suggested in that guide but adjusted the path line to the directory I created)
i.e.

[sambashare]
    comment = Samba on Ubuntu
    path = /root/samba
    read only = no
    browsable = yes



root@ubuntu-s-1vcpu-1gb-intel-nyc1-01:~# sudo service smbd restart
root@ubuntu-s-1vcpu-1gb-intel-nyc1-01:~# sudo ufw allow samba

( could use any username but used root)

root@ubuntu-s-1vcpu-1gb-intel-nyc1-01:~# sudo smbpasswd -a root
New SMB password:
Retype new SMB password:
Added user root.

我可以通过 SSH 连接到该 ubuntu 服务器...并且在那里看到 0.0.0.0:22。

当我从另一台计算机执行

$nmap -p22,445 157.111.214.123
Starting Nmap 7.91 ( https://nmap.org ) at 2021-04-24 02:44 GMT Daylight Time
Nmap scan report for 157.111.214.123
Host is up (0.084s latency).

PORT    STATE    SERVICE
22/tcp  open     ssh
445/tcp filtered microsoft-ds

Nmap done: 1 IP address (1 host up) scanned in 2.43 seconds

（据我所知，“过滤”与关闭一样好..因此，端口回复不是关闭的，而是根本不回复..因此某些设备（例如防火墙）没有响应来表明端口是打开的）。

当我尝试从（我敢说是 Windows 机器）访问 SAMBA 共享时，例如\\IP或 net use \\IP，它不起作用。但这并不奇怪，因为 nmap 显示端口 445 未打开。
