如何在8080上通過局域網訪問網頁（由Ubuntu上的Pycharm許可證服務器提供服務）

Question

我試圖在局域網上設置一個PyCharm License Server。

我有一臺Ubuntu 16.04服務器，hightower設置要做到這一點。我已經安裝了許可證服務器，它似乎在8080成功運行：

admin@hightower:/opt/jetbrains$ sudo bin/license-server.sh start 
Starting JetBrains License Service...

* Started @1055ms 
* JetBrains License Service is listening on {hightower:8080} 
JetBrains License Service is running 

但我不能從另一臺計算機訪問webpage at 8080在局域網上，爲了繼續這一進程。

從工作站，01-e局域網與GUI/Ubuntu的16.04上，試圖訪問hightower:8080或http://hightower:8080/register或192.168.0.7:8080或hightower.domain.local:80801或任何組合給了我：

的Firefox無法建立到連接服務器在hightower：8080。

我可以ping陶瑋：

...-01-e:~$ ping hightower 
PING hightower.domain.local (192.168.0.7) 56(84) bytes of data. 
64 bytes from hightower.domain.local (192.168.0.7): icmp_seq=1 ttl=64 time=0.170 ms 

防火牆不上，在黑暗中的服務器hightower

admin@hightower:/opt/jetbrains$ sudo ufw status 
Status: inactive 

刺痛，看看是否實際上是被服務的頁面：

admin@hightower:/opt/jetbrains$ wget hightower:8080 
--2017-01-30 13:47:38-- http://hightower:8080/ 
Resolving hightower (hightower)... 127.0.1.1

Reusing existing connection to hightower:8080. 
HTTP request sent, awaiting response... 200 OK 

所以如何使此頁面在我的局域網中可見？

編輯：額外的挖掘，它看起來8080只被提供給本地主機。我猜這是問題所在。

admin@hightower:/opt/jetbrains$ netstat -nl 
Active Internet connections (only servers) 
Proto Recv-Q Send-Q Local Address   Foreign Address   State  
tcp  0  0 0.0.0.0:22    0.0.0.0:*    LISTEN  
tcp6  0  0 127.0.1.1:8080   :::*     LISTEN  
tcp6  0  0 :::22     :::*     LISTEN  
tcp6  0  0 127.0.0.1:33247   :::*     LISTEN 

編輯：

admin@hightower:~$ cat /etc/hosts 
127.0.0.1 localhost 
127.0.1.1 hightower 

# The following lines are desirable for IPv6 capable hosts 
::1  localhost ip6-localhost ip6-loopback 
ff02::1 ip6-allnodes 
ff02::2 ip6-allrouters 

Answer 1

固定它。我只好跑：

<license_server_home>/bin/license-server.sh configure --port 8080 --listen 0.0.0.0 

，而不是建議：

<license_server_home>/bin/license-server.sh configure --port 8080 --listen license-server.mydomain.com 

我可能也改變了/ etc/hosts來閱讀：

admin@hightower:~$ cat /etc/hosts 
127.0.0.1 localhost 
0.0.0.0  hightower 

但它推薦給我這是不好的做法，因爲我只想要一個端口可以訪問。
