远程连接WSL2

WSL2开启SSH. 按照网上的教程1折腾了一下，据说自带的OpenSSH有问题，需要先卸后装先配置一下源,看下/etc/os-release： PRETTY_NAME=”Ubuntu 22.04.3 LTS” NAME=”Ubuntu” VERSION_ID=”22.04″ VERSION=”22.04.3 LTS (Jammy Jellyfish)” 配置相应版本的源

先卸后装openssh

sudo apt remove openssh-server
sudo apt install openssh-server

1 2	sudo apt remove openssh-server sudo apt install openssh-server

然后修改配置文件，这里还是用的密码登录，密钥的差不多处理

Port 2222   #设置ssh的端口号, 由于22在windows中有别的用处, 尽量不修改系统的端口号
PermitRootLogin yes   # 可以root远程登录
PasswordAuthentication yes     # 允许密码验证登录
AllowUsers dancingline # 远程登录时的用户名

Port 2222 #设置ssh的端口号, 由于22在windows中有别的用处, 尽量不修改系统的端口号

PermitRootLogin yes # 可以root远程登录

PasswordAuthentication yes # 允许密码验证登录

AllowUsers dancingline # 远程登录时的用户名

然后重启服务

sudo service ssh --full-restart

1	sudo service ssh --full-restart

新装的ssh可能不是默认开机自启的，顺便设置了

sudo systemctl enable ssh

1	sudo systemctl enable ssh

同样的，Windows上自带的OpenSSH（如果装了的话）也有问题，就是连不上，需要重新装一个或者用Xshell之类的软件来连接，或者参考2把环境变量里的ssh换成一个正常的（比如git bash自带的那个）。然后应该可以在Windows上用powershell连接了

ssh -P2222 dancingline@localhost # 注意Windows上的ssh命令跟linux略有不同，端口号要用-P参数指定

1	ssh -P2222 dancingline@localhost # 注意Windows上的ssh命令跟linux略有不同，端口号要用-P参数指定

Windows端口转发上一步只能保证本机连接到WSL，为了能在局域网甚至外网上进行连接，需要进行一些设置，主要分为两步：首先在Windows防火墙设置端口，给刚才设定的SSH端口2222添加入站规则，这部分参考3 ；然后是端口转发，这里有一个比较严重的问题，WSL2每次重启都会换IP，在网上4找了个powershell脚本，摘录如下（运行需要管理员权限）

# 找到WSL2的IP
$ip = bash.exe -c "ifconfig eth0 | grep 'inet '"
$found = $ip -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';
if( $found ) {
    $ip = $matches[0];
    echo "Found IP $ip"
    # 端口转发，listenport和listenaddress表示监听的端口和IP，connectport和connectaddress表示转发到的端口和IP
    iex "netsh interface portproxy add v4tov4 listenport=2222 listenaddress=* connectport=2222 connectaddress=$ip";
    # 展示已有的
    iex "netsh interface portproxy show all;"
}
else { echo "The ip address of WSL2 cannot be found!"; }

# 如果不想用了，下面可以删除端口转发
# netsh interface portproxy delete v4tov4 listenport=2222 protocol=tcp

# 找到WSL2的IP

$ip = bash.exe -c "ifconfig eth0 | grep 'inet '"

$found = $ip -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';

if( $found ) {

$ip = $matches[0];

echo "Found IP $ip"

# 端口转发，listenport和listenaddress表示监听的端口和IP，connectport和connectaddress表示转发到的端口和IP

iex "netsh interface portproxy add v4tov4 listenport=2222 listenaddress=* connectport=2222 connectaddress=$ip";

# 展示已有的

iex "netsh interface portproxy show all;"

}

else { echo "The ip address of WSL2 cannot be found!"; }

# 如果不想用了，下面可以删除端口转发

# netsh interface portproxy delete v4tov4 listenport=2222 protocol=tcp

可以把这个脚本命名forward_wsl2_port.ps1, 放进Windows计划任务开机自动执行。，具体操作是：右键点win开始按钮，选择computer management, 选择Computer Management(Local) –> System Tools –> Task Scheduler –> Task Scheduler Library, 在Task Scheduler Library上右键，选择 Read more…

webmin安装及模块proftpd

在arm kylin服务器上安装webmin 1 官网下载最新的webmin-2.013.tar.gz，并解压到/usr/local/webmin/ 2 运行/usr/local/webmin/setup.sh 安装proftpd：下载和编译安装proftpd:

wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.8.tar.gz
tar -zxvf proftpd-1.3.8.tar.gz
cd proftpd-1.3.8
./configure --prefix=/usr/local/proftpd --sysconfdir=/usr/local/proftpd
make  && make install

wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.8.tar.gz

tar -zxvf proftpd-1.3.8.tar.gz

cd proftpd-1.3.8

./configure --prefix=/usr/local/proftpd --sysconfdir=/usr/local/proftpd

make && make install

编写service启动文件：

[root@installer55 proftpd-1.3.8]# cat /usr/lib/systemd/system/proftpd.service 
[Unit]
Description = ProFTPD FTP Server
After = network.target nss-lookup.target local-fs.target remote-fs.target

[Service]
Type = forking
PIDFile = /usr/local/proftpd/var/proftpd.pid
Environment = PROFTPD_OPTIONS=
EnvironmentFile = -/etc/sysconfig/proftpd
ExecStart = /usr/sbin/proftpd $PROFTPD_OPTIONS
ExecReload = /bin/kill -HUP $MAINPID

[Install]
WantedBy = multi-user.target

[root@installer55 proftpd-1.3.8]# cat /usr/lib/systemd/system/proftpd.service

[Unit]

Description = ProFTPD FTP Server

After = network.target nss-lookup.target local-fs.target remote-fs.target

[Service]

Type = forking

PIDFile = /usr/local/proftpd/var/proftpd.pid

Environment = PROFTPD_OPTIONS=

EnvironmentFile = -/etc/sysconfig/proftpd

ExecStart = /usr/sbin/proftpd $PROFTPD_OPTIONS

ExecReload = /bin/kill -HUP $MAINPID

[Install]

WantedBy = multi-user.target

启动和错误处理

1、启动
  systemctl start proftpd
2、启动会报错
  这里报错：- Fatal: Group: Unknown group &#39;nogroup&#39;.
3、处理修改配置文件
   vi /usr/local/proftpd/proftpd.conf
   --修改前
   # Set the user and group under which the server will run.
  User                             nobody
  Group                            nogroup
  --修改后
  # Set the user and group under which the server will run.
  User                             nobody
  Group                            nobody
4、再次启动即可

1、启动

systemctl start proftpd

2、启动会报错

这里报错：- Fatal: Group: Unknown group 'nogroup'.

3、处理修改配置文件

vi /usr/local/proftpd/proftpd.conf

--修改前

# Set the user and group under which the server will run.

User nobody

Group nogroup

--修改后

# Set the user and group under which the server will run.

User nobody

Group nobody

4、再次启动即可

配置用户及目录

1、建目录和用户
  建立目录 mkdir -p /data/
  建立用户 useradd -d /data/ftp -s /sbin/nologin ftp_user
  配置密码 echo ftp_user|passwd --stdin ftp_user
 修改权限 chown -R ftp_user:ftp_user /data/ftp
2、添加配置文件，在配置文件末尾添加如下代码
 vi /usr/local/proftpd/proftpd.conf
  <Directory /data/ftp>
     HideNoAccess off
      <Limit STOR MKD>
       Order deny,allow
       allowUser  ftp_user
      </Limit>
  </Directory>

3、重启服务 

4、登录ftp查看
可以在windows文件管理器里打开ftp://x.x.x.x/
可以用wget命令下载：
wget -nH -m -r --ftp-user=ftp_user --ftp-password='ftp_user'  ftp://x.x.x.x/aarch64-kylin/20230224/a.txt

1、建目录和用户

建立目录 mkdir -p /data/

建立用户 useradd -d /data/ftp -s /sbin/nologin ftp_user

配置密码 echo ftp_user|passwd --stdin ftp_user

修改权限 chown -R ftp_user:ftp_user /data/ftp

2、添加配置文件，在配置文件末尾添加如下代码

vi /usr/local/proftpd/proftpd.conf

HideNoAccess off

Order deny,allow

allowUser ftp_user

</Limit>

</Directory>

3、重启服务

4、登录ftp查看

可以在windows文件管理器里打开ftp://x.x.x.x/

可以用wget命令下载：

wget -nH -m -r --ftp-user=ftp_user --ftp-password='ftp_user' ftp://x.x.x.x/aarch64-kylin/20230224/a.txt

登录报错： Invalid shell: ‘/usr/sbin/nologin’ 解决： vim /etc/shells 结尾添加： /usr/sbin/nologin /sbin/nologin 下载安装proftpd webmin模块： 2 wget https://download.webmin.com/download/modules/proftpd.wbm.gz 2 打开webmin页面上的模块管理，从页面上选择服务器路径进行模块安装

VScode Unable to load schema

打开ansible yaml文件，经常报错：

Unable to load schema from 'http://json.schemastore.org/ansible-stable-2.9': connect ETIMEDOUT 137.117.17.70:80

1	Unable to load schema from 'http://json.schemastore.org/ansible-stable-2.9': connect ETIMEDOUT 137.117.17.70:80

是代理的问题，可添加代理：

Press F1
Type user settings.
Select Preferences:Open User Settings from drop down
Put below code and modify accordingly

"http.proxy": "http://username:password@hostname:port/",
"http.proxyAuthorization": null,
"http.proxyStrictSSL": true

Press F1

Type user settings.

Select Preferences:Open User Settings from drop down

Put below code and modify accordingly

"http.proxy": "http://username:password@hostname:port/",

"http.proxyAuthorization": null,

"http.proxyStrictSSL": true

我选择关闭代理：

"http.proxy": "",
"http.proxyAuthorization": null,
"http.proxyStrictSSL": false

"http.proxy": "",

"http.proxyAuthorization": null,

"http.proxyStrictSSL": false

烦人的报错提示终于消失了
