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)
結果重開機之後發現原本在打tunnel 連 ptt 的 wireguard VPN 掛掉了
手動下指令也啟動不了
查了一下發現是 ubuntu 18.04 kernel 4.15.0-106 的包
看來就連kernel 最好都不要自動升級...
<!--more-->
一開始不管怎麼下指令要啟動wireguard Interface 都會出錯
```
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"
```
因為很久沒動了所以wireguard config 檔案應該是沒有問題
不過還是檢查看看?
```
root@hqdc034:~# wg showconf wg0
Unable to access interface: Protocol not supported
```
很好果然不是config 的問題看來是wireguard 某些套件有狀況了
用modprobe 檢查一下
```
root@hqdc034:~# modprobe wireguard
modprobe: FATAL: Module wireguard not found in directory /lib/modules/4.15.0-106-generic
```
OK 找到問題了看起來是新版本的kernel 有某些狀況?
anyway
要解決其實很簡單,要不就直接上 20.04 XD
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)
```
root@hqdc034:~# apt-get install wireguard-dkms wireguard-tools linux-headers-$(uname -r)
正在讀取套件清單... 完成
正在重建相依關係
正在讀取狀態資料... 完成
linux-headers-4.15.0-106-generic 已是最新版本 (4.15.0-106.107)。
linux-headers-4.15.0-106-generic 被設定為手動安裝。
wireguard-tools 已是最新版本 (1.0.20200513-1~18.04)。
wireguard-tools 被設定為手動安裝。
以下套件為自動安裝,並且已經無用:

python-psycopg2 python3-flask-htmlmin python3-htmlmin sntp
使用 'apt autoremove' 將之移除。
下列套件將會被升級:
wireguard-dkms
升級 1 個,新安裝 0 個,移除 0 個,有 123 個未被升級。

<description>&lt;p&gt;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)&lt;/p&gt;
&lt;p&gt;結果重開機之後發現原本在打tunnel 連 ptt 的 wireguard VPN 掛掉了&lt;/p&gt;
&lt;p&gt;手動下指令也啟動不了&lt;/p&gt;
&lt;p&gt;查了一下發現是 ubuntu 18.04 kernel 4.15.0-106 的包&lt;/p&gt;
&lt;p&gt;看來就連kernel 最好都不要自動升級&amp;hellip;&lt;/p&gt;</description>

<p>前幾天公司的一台 Synology DS 415+ 發生異常</p>
<p>注意到的時候,四顆硬碟燈號都不斷的在閃爍</p>
<p>但是已經無法登入系統</p>
<p>重開機之後更慘,四顆硬碟燈號全部橘燈恆亮</p>
<p>底下的電源藍燈不斷的在閃爍</p>
<p>因為工作的關係現在很多時間都花在VIM的操作上</p>
<p>雖然我一再表示不希望送修了</p>
<p>所以之前花了滿多時間調整出一個適合自己的VIM環境</p>
<p>一來是已經過保二來是DS415+ 本身就有intel bug三來是因為對synology的NAS 實在沒有愛&hellip;</p>
<p>原本的作法是把這個設定好的環境丟到自己建立的gitea 上面</p>
<p>不過主管還是希望能夠先問群暉維修的費用多少</p>
<p>然後每到一台新的機器就要去clone 下來</p>

<p>想做一個 10G 的 LAB 環境出來已經很久了。</p>
<p>只是礙於10G RJ45的卡太貴了然後光纖的種類又太複雜</p>
<p>前幾天公司的一台 Synology DS 415+ 發生異常</p>
<p>如果直接在淘寶購買,很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
<p>注意到的時候,四顆硬碟燈號都不斷的在閃爍</p>
<p>所以一直沒有付諸行動。</p>
<p>但是已經無法登入系統</p>
<p>硬體的工作很久沒碰了,剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡以在台灣的價格來說算很便宜的 (550)</p>
<p>重開機之後更慘,四顆硬碟燈號全部橘燈恆亮</p>
<p>聊了一下,跟他請教了關於線材、光纖模塊的問題,回答也都很快很到位</p>
<p>底下的電源藍燈不斷的在閃爍</p>
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p>
<p>雖然我一再表示不希望送修了</p>
<p>就是到貨有點久,等了兩個禮拜左右,一直到昨天東西才寄到</p>
<p>一來是已經過保二來是DS415+ 本身就有intel bug三來是因為對synology的NAS 實在沒有愛&hellip;</p>
<p>今天就花了點時間測試一下</p>
<p>不過主管還是希望能夠先問群暉維修的費用多少</p>

<p>Bookstack 是一套非常好用的線上&rdquo;筆記&rdquo;系統</p>
<p>他用圖書館/書本的概念,讓使用者可以建立自己的&rdquo;圖書館&rdquo;</p>
<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
<p>而且支援 Markdown 語法</p>
<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
<p>或者是boostnote(只能在本機)</p>
<p>都或多或少有點小缺點</p>
<p>Bookstack則是沒有這些問題不過就是系統「大」了點&hellip;</p>
<p>不過還好有人做成docker的方式來啟動大大的降低了建置的難度(其實也沒有很難啦只是要裝個PHP、弄個DB而已)</p>

<title>Ubuntu 18.04 Kernel 4.15.0-106 Unable to Start Wireguard Interface</title>

<description>&lt;p&gt;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)&lt;/p&gt;
&lt;p&gt;結果重開機之後發現原本在打tunnel 連 ptt 的 wireguard VPN 掛掉了&lt;/p&gt;
&lt;p&gt;手動下指令也啟動不了&lt;/p&gt;
&lt;p&gt;查了一下發現是 ubuntu 18.04 kernel 4.15.0-106 的包&lt;/p&gt;
&lt;p&gt;看來就連kernel 最好都不要自動升級&amp;hellip;&lt;/p&gt;</description>

<h1 class='entry-title'> Ubuntu 18.04 Kernel 4.15.0-106 Unable to Start Wireguard Interface</h1>
</div>
<div class="entry-container">
<div class="entry-content">
<article>
<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&hellip;</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 &quot;wg0&quot;
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 &quot;wg1&quot;
</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)

linux-headers-4.15.0-106-generic 已是最新版本 (4.15.0-106.107)。
linux-headers-4.15.0-106-generic 被設定為手動安裝。
wireguard-tools 已是最新版本 (1.0.20200513-1~18.04)。
wireguard-tools 被設定為手動安裝。
以下套件為自動安裝,並且已經無用:

python-psycopg2 python3-flask-htmlmin python3-htmlmin sntp
使用 'apt autoremove' 將之移除。
下列套件將會被升級:
wireguard-dkms
升級 1 個,新安裝 0 個,移除 0 個,有 123 個未被升級。
