在旧电脑里发现这个软件：

怀念那时的软件不用一堆的在线功能，小巧精焊，压缩完不到2M。

Ubuntu 22.04.1默认采用systemd-resolved作为DNS维护服务，其生成的/etc/resolv.conf文件内容如下：

# This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8).
# Do not edit.
#
# This file might be symlinked as /etc/resolv.conf. If you're looking at
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 192.168.1.1

如果需要修改DNS服务器，则修改文件/etc/systemd/resolved.conf中的DNS字段，示例:

#  This file is part of systemd.

#  terms of the GNU Lesser General Public License as published by the Free
#  Software Foundation; either version 2.1 of the License, or (at your option)
#  any later version.
#
# Entries in this file show the compile time defaults. Local configuration
# should be created by either modifying this file, or by creating "drop-ins" in
# the resolved.conf.d/ subdirectory. The latter is generally recommended.
# Defaults can be restored by simply deleting this file and all drop-ins.
#
# Use 'systemd-analyze cat-config systemd/resolved.conf' to display the full config.
#
# See resolved.conf(5) for details.

再重启服务生效：

sudo systemctl restart systemd-resolved

frps作为服务端，需要在Windows服务器上实现服务后台运行，借助winsw工具快速搞定，记录如下：

• 下载winsw
  https://github.com/winsw/winsw/releases
  下载对应的版本，如WinSW-x64.exe

• 填写服务配置文件
  配置文件名：WinSW-x64.xml，注意取名跟所下载的应用程序名WinSW-x64.exe相同，并放入同一目录下。

  <service>
  <!--  该服务的唯一标识  -->
  <id>frps</id>
  <!--  该服务的名称  -->
  <name>frp-server</name>
  <!--  该服务的描述  -->
  <description>frp服务器</description>
  <!--  要运行的程序路径  -->
  <executable>C:\bug\frp\frps.exe</executable>
  <!--  携带的参数  -->
  <startargument>-c</startargument>
  <startargument>C:\bug\frp\frps.toml</startargument>
  <!--  第一次启动失败 60秒重启  -->
  <onfailure action="restart" delay="60 sec"/>
  <!--  第二次启动失败 120秒后重启  -->
  <onfailure action="restart" delay="120 sec"/>
  <!--  日志模式  -->
  <logmode>append</logmode>
  <!--  指定日志文件目录(相对于executable配置的路径)  -->
  <logpath>logs</logpath>
  </service>

• 安装并启动服务

  以管理员权限运行cmd:

    WinSW-x64.exe install
    WinSW-x64.exe start

• 查看log
  找到配置文件所在的logs目录查看即可。
