尝试打开端口 8000

尝试打开端口 8000

我有一台运行 Ubuntu 的 Nvidia Jetson。我正在尝试设置 web2py。当我在 Jetson 上使用 Chrome 时,它​​会显示 web2py 的“hello world”,但当我使用本地网络上另一台机器的浏览器时,它无法连接。

在 Jetson 上:

jrraines@Georgejetson:~$ nmap localhost

在网络上的 Raspberry Pi 上:

pi@rpi-HRA:~ $ sudo nmap 192.168.0.125

当我看到这个时,我意识到我也从来没有能够使用 VNC 连接到 Jetson。
