설정

1. WSL을 microsoft 설명서에 설명된 순서대로 설치
2. c:\wsl2_network 경로에 wsl2_network.bat, wsl2_network.ps1 파일 생성. ps1 파일의 ports(16번째 줄)에 forwarding을 원하는 port 기입.
3. root 비밀번호를 생성하고 apt 패키지 관리자 update 및 upgrade

bash
sudo passwd root
su
apt update && apt upgrade

4. net-tools와 openssh-server 설치

apt install net-tools openssh-server

5. vi /etc/ssh/sshd_config -> Port는 원하는 값으로 PasswordAuthentication는 yes로 변경

vi /etc/ssh/sshd_config
:%s/#Port 22/Port 2222
:%s/#PasswordAuthentication no/PasswordAuthentication yes

6. ssh 서비스 접근시 비밀번호를 묻지 않게 설정

su
echo "%sudo ALL=NOPASSWD: /etc/init.d/ssh" >> /etc/sudoers

7. ssh 서비스 재시작

/etc/init.d/ssh restart

8. windows 관리자권한 powershell에서 batch file을 스케줄러에 등록. 본인의 username을 입력하고 실행하면 비밀번호 입력 창이 뜬다.

schtasks /create /ru username /rp /sc onstart /tn wsl2_network /tr c:\wsl2_network\wsl2_network.bat /rl highest

sshd: no hostkeys available -- exiting. 발생시

sudo ssh-keygen -A

wsl2_network.bat

@echo off
powershell.exe -ExecutionPolicy Bypass -File C:\wsl2_network\wsl2_network.ps1
bash -c "sudo /etc/init.d/ssh restart"
exit

wsl2_network.ps1
