RaspberryPi 2/3をavahi-browseで検索できるようにする #RaspberryPi

RaspberryPi 2のRaspbian Stretch を使用しています。

avahi-daemonは最初から入っていたのですが、デフォルトでは設定が足りないようです。
NanoPi Neoと見比べて、以下のファイルをコピーしたらうまくいくようになりました。

/etc/avahi/services/ssh.service

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">

<service-group>

  <name replace-wildcards="yes">%h</name>

  <service>
    <type>_ssh._tcp</type>
    <port>22</port>
  </service>

</service-group>

これでRaspberryPi2を再起動。
PCのLinuxからavahi-browseコマンドで見つかるようになりました。

$ avahi-browse -a -t |grep rasp
+   eth1 IPv6 raspberrypi                                   SSH Remote Terminal  local
+   eth1 IPv4 raspberrypi                                   SSH Remote Terminal  local

これで以下のようにしてsshでログインできます。

$ ssh pi@raspberrypi.local
