WSL2 Ubuntu にホストWindowsからRDP接続したい
解決したいこと
質問 Windows 11 WSL2 (Ubuntu) のIPアドレスとxrdp の続きです。
Winows 11 Pro 25H2 で WSL2 を有効化して Ubuntu 24.04.3 LTS (Noble Numbat) をインストールし、ネットワークモードは Nat で稼働させています。そこまでの経緯は上記の質問にあります。
WSL Settings のネットワークモードが Nat なので、Ubuntu ではホストの Windows と異なる IPv4 アドレスとなっています。そこで、この Ubuntu で xrdp を動かし、ホストの Windows のリモートデスクトップ接続 (mstsc.exe) で、Ubuntu の IPv4 アドレスを指定して接続してみたい。
xrdp を稼働させるまでの手順は下記のように行いました。
sudo apt update
sudo apt upgrade
sudo apt install ubuntu-desktop
sudo apt install xrdp
sudo adduser xrdp ssl-cert
sudo systemctl restart xrdp
RDP接続は下記の手順で試しました。
- Ubuntu からログアウト
- Windows で リモートデスクトップ接続 を実行
発生している問題・エラー
リモートデスクトップ接続 を実行して Ubuntu の IPv4 アドレスを入力すると、ウィンドウが開いてログイン画面は出るのですが、数秒後にウィンドウが勝手に閉じてしまい、ログインが不可能です。
そこで Ubuntu にコンソールでログインして、ログを見てみました。

[ERROR] がありますね。
いろいろ検索して調べましたが、まだどのエラーも原因がつかめません。
何か情報がありましたらご教授いただければ幸いです。
