如何通过 LAN 在 8080 上访问网页（由 Pycharm 许可证服务器提供服务，位于 Ubuntu）
How to access webpage (served by Pycharm License Server, on Ubuntu) on 8080 over LAN
我正在尝试在我的 LAN 上设置 PyCharm License Server。
我有一个 Ubuntu 16.04 服务器，hightower 设置用于执行此操作。我已经安装了许可证服务器，它似乎在 8080:

但是我无法从局域网上的另一台计算机访问 webpage at 8080，以便继续该过程。
从工作站 01-e 在 LAN 上使用 GUI/Ubuntu 16.04，尝试访问 hightower:8080 或 http://hightower:8080/register 或 192.168.0.7:8080 或 hightower.domain.local:80801 或任何组合给我：
Firefox can’t establish a connection to the server at hightower:8080.
我可以 ping hightower:
...-01-e:~$ ping hightower
PING hightower.domain.local (192.168.0.7) 56(84) bytes of data.

那么如何让这个页面在我的 LAN 上可见？
编辑：进一步挖掘，似乎 8080 仅提供给本地主机。我猜这就是问题所在。

已修复。我不得不 运行:
<license_server_home>/bin/license-server.sh configure --port 8080 --listen 0.0.0.0
而不是建议的：
<license_server_home>/bin/license-server.sh configure --port 8080 --listen license-server.mydomain.com
我可能也可以将 /etc/hosts 更改为：
admin@hightower:~$ cat /etc/hosts
127.0.0.1 localhost
0.0.0.0 hightower
但有人向我推荐这不是一个好的做法，因为我只想访问一个端口。
