Quick start

Installation

releases

Download the corresponding system version, the server and client are separate.

Server start

After downloading the server compressed package, unzip it, and then enter the unzipped folder.

  • execute installation command

For linux、darwin sudo ./nps install

For windows, run cmd as administrator and enter the installation directory nps.exe install

  • default ports

The default configuration file of nps use 80,443,8080,8024 ports

80 and 443 ports for host mode default ports

8080 for web management access port

8024 for net bridge port, to communicate between server and client

  • start up

For linux、darwin sudo nps start

For windows, run cmd as administrator and enter the program directory nps.exe start

After installation, the windows configuration file is located at C:\Program Files\nps, linux or darwin is located at /etc/nps

If you don't find it started successfully, you can check the log (Windows log files are located in the current running directory, linux and darwin are located in /var/log/nps.log).

  • Access server IP:web service port (default is 8080).
  • Login with username and password (default is admin/123, must be modified when officially used).
  • Create a client.

Client connection

  • Click the + sign in front of the client in web management and copy the startup command.
  • Execute the startup command, Linux can be executed directly, Windows will replace ./npc with npc.exe and execute it with cmd.

If you need to register to the system service, you can check Register to the system service

Configuration

  • After the client connects, configure the corresponding penetration service in the web.
  • For more advanced usage, see Complete Documentation

Contribution

  • If you encounter a bug, you can submit it to the dev branch directly.
  • If you encounter a problem, you can feedback through the issue.
  • The project is under development, and there is still a lot of room for improvement. If you can contribute code, please submit PR to the dev branch.
  • If there is feedback on new features, you can feedback via issues or qq group.

  • Windows版本内存与当前TCP连接数持续增长

    Windows版本内存与当前TCP连接数持续增长

    Windows版本服务端,nps程序占用的内存与当前TCP连接数会持续增大,不会随使用的具体情况下降。

    NPS使用情况 1、客户端4个 2、TCP隧道70个左右,用于RDP及SQL连接 3、几个域名解析(不使用https)

    即使是深夜,使用量极少的时候 内存与当前TCP连接数都会持续增长。 内存 深夜每两分钟增长5-10MB,白天10-150MB。 当前TCP连接数 没有仔细监控,看过的较高的数字可以达到4万,是否在Windows环境此功能是不准的?

    客户端内存也是持续增大,重启客户端 可以使服务端的当前TCP连接数 从几万迅速降到一两千,但无法使用服务端内存下降。

    主要是遇到内存过大,导致操作系统异常的问题。为解决此问题,只能写了个程序用于检测内存占用情况,以及定时重启。

    这是一直存在的问题,希望后续版本能修正。

    服务器配置,Windows Server 2019 1809 x64,4核8G,10M带宽(实际使用量不到3M) NPS版本:基于v0.26.7,去除了nps服务部署,改用nssm运行程序

    (安全端口未开放)nps域名解析问题

    在按照官网文档操作时 我在本地5000端口启了一个web服务。想通过a.myhost.com直接访问

    我在nps的web端域名解析配置 域名:a.myhost.com 内网目标(ip:端口) :127.0.0.1:5000 客户端id:对应客户端的id

    这个时候我访问的时候a.myhost.com,没有正常响应。

    是我操作的问题吗

    编译报错 go build cmd/proxy_client/proxy_client.go 提示找不到utils包

    尝试复制utils文件夹到对应目录,会报错更多信息。。。 还请指点下如果能正常编译出来,谢谢!

    如果采用 git checkout tag v.17 再进行编译,可以成功生成bin文件。 不过和当前版本应该有很多不一样,那个是客户端和服务端都在一个可执行程序里面。
