WSL2 ubuntu18.04配置3 配置ssh远程登陆

WSL中已经内置了ssh服务，但是看到有帖子说自带的ssh有问题，因此卸载掉重新安装

ss                ssdpapi.dll       ssh-agent         ssh-import-id-gh  ssh-keyscan.exe   sstpsvc.dll
ssText3d.scr      ssdpsrv.dll       ssh-agent.exe     ssh-import-id-lp  ssh.exe           sstpsvc.mof
sscore.dll        ssh               ssh-argv0         ssh-keygen        sshd
sscoreext.dll     ssh-add           ssh-copy-id       ssh-keygen.exe    sspicli.dll
ssdm.dll          ssh-add.exe       ssh-import-id     ssh-keyscan       sspisrv.dll

2

2.安装ssh

apt-get install openssh-server

3. 安装ifconfig工具

apt-get install net-tools

4. 配置ssh服务

先备份，后修改哦

cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bk
vi /etc/ssh/sshd_config

修改的内容如下

Port 22#远程端口为22 默认
ListenAddress 0.0.0.0#监听地址为0.0.0.0表示监听所有来访的ip
PasswordAuthentication yes#允许用户通过密码登陆
PermitRootLogin yes#允许root用户登陆

查看ip地址

ifconfig

可以看到内网地址为172.18.225.147

7.在局域网下进行ssh登陆

这里使用的软件是mobaxterm，其他ssh登陆工具用法类似
输入ip地址，指定用户名和端口号

登陆后界面

8. 开机启动ssh服务

添加 service ssh start

vi /etc/init.wsl
