VMwareのubuntuから他のubuntuに通信するとき(ROS2など)が上手くいかないとき

Posted at

具体例

・VMwareのubuntuからラズパイ4のubuntuとROS2で通信(talkerやlistenerなど)をやろうとした時に上手く行かなかった
・SSHやpingは上手くいく

原因

・VMware上のubuntuのネットワーク設定(NAT→ブリッジにするとうまくいく)
・NATだと一旦ホスト(僕はWindows)を経由するけどブリッジはしないっぽい
・ブリッジへの設定はアダプタ(WiFi含む)の設定に気をつける

教訓

・仮想マシンから通信するとき、OSに依存するやつは気をつけなきゃいけない
