### vpnに接続する方法

まずは、pritunl-serverを立ち上げて、profileをdownload(or rewirte)します。

次に、clientを使い接続します。この辺の仕組みは一度構築すると便利に使えます。usbは外で使う事が多く、local-networkに入るための手段を確立しておくことは重要です。

```sh:/etc/pacman.conf
[pritunl]
Server = https://repo.pritunl.com/stable/pacman
```

```sh
$ sudo pacman-key --keyserver hkp://keyserver.ubuntu.com -r 7568D9BB55FF9E5287D586017AE645C0CF8E292A
$ sudo pacman-key --lsign-key 7568D9BB55FF9E5287D586017AE645C0CF8E292A
$ sudo pacman -Sy
$ sudo pacman -S pritunl-client-electron
$ sudo pacman -S pritunl-client-electron-numix-theme
$ pritunl-client-electron
# ここでprofile(.vpn)をimport

$ git clone https://github.com/cghdev/gotunl.git
$ cd gotunl
$ go install
$ ./${GOPATH}/bin/gotunl -l
$ ./${GOPATH}/bin/gotunl -c 1
```
