<p>工作用的電腦，昨天終於難得的reboot了(uptime 看了一下，大概是三百多天)</p>
|
|
|
|
|
|
<p>結果重開機之後，發現原本在打tunnel 連 ptt 的 wireguard VPN 掛掉了</p>
|
|
|
|
|
|
<p>手動下指令也啟動不了</p>
|
|
|
|
|
|
<p>查了一下發現是 ubuntu 18.04 kernel 4.15.0-106 的包</p>
|
|
|
|
|
|
<p>看來就連kernel 最好都不要自動升級…</p>
|
|
|
|
|
|
<p>一開始不管怎麼下指令要啟動wireguard Interface 都會出錯</p>
|
|
|
|
|
|
<pre><code>root@hqdc034:~# wg-quick up wg0
|
|
|
[#] ip link add wg0 type wireguard
|
|
|
RTNETLINK answers: Operation not supported
|
|
|
Unable to access interface: Protocol not supported
|
|
|
[#] ip link delete dev wg0
|
|
|
Cannot find device "wg0"
|
|
|
root@hqdc034:~# wg-quick up wg1
|
|
|
[#] ip link add wg1 type wireguard
|
|
|
RTNETLINK answers: Operation not supported
|
|
|
Unable to access interface: Protocol not supported
|
|
|
[#] ip link delete dev wg1
|
|
|
Cannot find device "wg1"
|
|
|
</code></pre>
|
|
|
|
|
|
<p>因為很久沒動了，所以wireguard config 檔案應該是沒有問題</p>
|
|
|
|
|
|
<p>不過還是檢查看看？</p>
|
|
|
|
|
|
<pre><code>root@hqdc034:~# wg showconf wg0
|
|
|
Unable to access interface: Protocol not supported
|
|
|
</code></pre>
|
|
|
|
|
|
<p>很好，果然不是config 的問題，看來是wireguard 某些套件有狀況了</p>
|
|
|
|
|
|
<p>用modprobe 檢查一下</p>
|
|
|
|
|
|
<pre><code>root@hqdc034:~# modprobe wireguard
|
|
|
modprobe: FATAL: Module wireguard not found in directory /lib/modules/4.15.0-106-generic
|
|
|
</code></pre>
|
|
|
|
|
|
<p>OK ，找到問題了，看起來是新版本的kernel 有某些狀況？</p>
|
|
|
|
|
|
<p>anyway</p>
|
|
|
|
|
|
<p>要解決其實很簡單，要不就直接上 20.04 XD</p>
|
|
|
|
|
|
<p>要不就重裝 wireguard-dkms (這個似乎是新釋出的套件，本來沒有這個的)</p>
|
|
|
|
|
|
<pre><code>root@hqdc034:~# apt-get install wireguard-dkms wireguard-tools linux-headers-$(uname -r)

|
|
|
使用 'apt autoremove' 將之移除。

下列套件將會被升級：
