<p>之前總部和分公司之間 是用buffalo 的小AP 灌 openwrt</p>
<p>然後用strongswan 來打 IPSEC site to site VPN</p>
<p>config 看起來不是很難 (只是看起來)</p>
<p>但是實際上已經找不到當初的文件</p>
<p>所以要維護很困難(光那些RSA KEY 就不知道為何、如何產生)</p>
<p>後來採購了兩台edgerouter X 做測試</p>
<p>也用openvpn 成功的建立了 site to site VPN</p>
<p>本來想說 openvpn 已經夠簡單了</p>
<p>今天看到文章說用wireguard 可以更簡單</p>
<p>於是研究了一下,發現還真的很簡單!</p>

<p>之前為了能夠在執行完 ansible playbook 後能有個log 可以看</p>
<p>所以在每次執行的時候,都要加入 tee 的指令</p>
<p>像是</p>
<pre><code>ANSIBLE_CONFIG=/home/D/ansiblecontrol/ansible.cfg /usr/local/bin/ansible-playbook /home/D/ansiblecontrol/playbook.user_client.yml --vault-password-file=/home/D/ansiblecontrol/vault.passwd -i /home/D/ansiblecontrol/inventory/production -f1 --limit tyuserclients |tee /tmp/tyuserclients.log
</code></pre>
<p>一直都是放在crontab 裡面執行,也就沒有去管他</p>
<p>反正也沒有人關心結果怎樣 (攤手</p>

<p>今天發生一件有點詭異的事情,本來應該要經過某個指令才會產生的檔案</p>
<p>居然不知為何自己產生了,在我記憶中沒有去執行過那個指令</p>
<p>翻了一下 bash_history ,裡面也只有下過哪些指令,沒有紀錄時間,完全沒有參考價值(攤手)</p>
<p>所以翻了一下網路至少把這兩台主要跑ansible的機器的log功能補上紀錄所有指令以及時間的部份</p>
