<p>最近一直在玩 wireguard ，先前把各個分公司和總部的VPN 改用 wireguard 建立</p>
<p>想說再打個VPN tunnel 來當跳板連 ptt 好了</p>
<p>因為wireguard 建立很簡單，而且又可以指定想要繞出去的路由，不會影響原本的網路環境</p>
<p>本來是在vultr 的VPS上面建立這個tunnel</p>
<p>但是那台VPS連去ptt 很頓，卡卡的</p>
<p>所以改用google cloud platform 的free tier 來做</p>
<p>反正只是拿來當跳板，不會有什麼流量、運算產生，可以一直保持免費的狀態</p>

<p>因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN</p>
<p>雖然說其實沒有什麼不好，但是畢竟不是我建立的，而當初的文件也都不見了</p>
<p>完全沒辦法了解當時設計的邏輯，造成後續debug 困難</p>
<p>可以想像一下，一台VPN router ping 不到remote、ping不到internet、甚至ping不到自己 是要怎麼debug !?(翻桌</p>
<p>之前買了兩台edgerouter X 拿來玩了一下 wireguard，感覺還不錯，不過只有測試到點對點</p>
<p>這次試試看躲在gateway後面，看看能不能建立多點的VPN環境</p>

<p>工作上常會需要用ssh登入遠端主機檢查LOG，有必要的時候，還要把log複製回本機來處理。</p>
<p>以前都是傻傻的用 scp 傳檔案</p>
<p>之前就記得有這個xclip/xsel 可以用，但是一直沒有弄清楚怎麼執行</p>
<p>早上研究了一下，順便做個筆記。</p>

<p>最近因為一直碰到硬碟故障的問題，算起來那一批同時購買的5X顆 seagate 2T硬碟，已經有一半以上故障返修了&hellip;.</p>
<p>然後又因為一直沒有添購新的硬碟，只能用這些快過保/已過保的撐著</p>
<p>所以最近不斷的在更換機器內的硬碟，而且還沒有熱插拔！</p>
<p>也導致原本負責處理盤點資產的同事困擾，因為跟手邊的紀錄已經對不起來了</p>
<p>然後就變成要對資產的時候，需要一台一台登入，然後去下不同的指令，取得想要的硬體資訊，超級麻煩的！</p>
