Vyatta から VyOS への移行

Linux VyOS

Vyatta Core 6.3 で動かしていたルータを VyOS 1.0.4 に移行したので、その手順について。
だいたい 5 分ほどで終わります。

前半の OS イメージを入れ替える部分は、
Vyatta Core は VyOS になりました - JANOG (PDF) に。
後半の設定変更部分は、
Vyatta CORE 6.6R1 から VyOS 1.0.4 へ変更してみた - Soukaku's HENA-CHOKO Blog
に沿ってやってます。

まず、OS イメージの切り換え。VyOSの鍵を導入する。

vyatta@vyatta-0:~$ wget http://vyos.net/so3group_maintainers.key0

vyatta@vyatta-0:~$ sudo apt-key add so3group_maintainers.key
OK

続いて VyOS のイメージをダウンロード＆登録する。
デフォルトで通してますが、イメージ名の変更がいる場合や、設定を引き継がない場合は適宜変更してください。

vyatta@vyatta-0:~$ add system image http://mirror.vyos-users.jp/iso/release/1.0.4/vyos-1.0.4-amd64.iso

で、再起動

vyatta@vyatta-0:~$ reboot
Proceed with reboot? [confirm][y] (そのままリターン)

The system is going down for reboot NOW!^M

vyatta@vyatta-0:~$ Write failed: Broken pipe

(ここまで前半資料に沿ってます。ここから後の資料に沿って）

再起動したのを見計らって再接続すると、 VyOS に切り替わっているので、

$ ssh -i vyatta_key vyatta@vyatta.example.com
