Welcome to the netman!

Netman is a light weight network manage tool on Ubuntu. It consists of common network management tools. You can easily find network problems on your personal host using netman.

What can netman do?

Framework

Details

1. Accounting management

   1.1 Real-time monitoring of network equipment traffic and rate changes, based on Bmon tool.

   1.2 A log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as information source, based on vnstat tool.

2. Configuration management

   2.1 Show a network connection editor that supports adding, modifying, viewing and deleting connections, based on [nmtui](nmtui is a curses‐based TUI application for interacting with NetworkManager. When starting nmtui, the user is prompted to choose the activity to perform unless it was specified as the first argument.).

   2.2 Advanced network management deployed on IPMininet which can offer traffic engineering by SRv6.

3. Safty management

   3.1 Firewall configuration based on ufw, including open/close firewall, allow/deny specific ports or services, check firewall status, etc.

   3.2 Check whether there are dangerous ports in use automatically, based on netstat and a list of dangerous ports.

4. Performance management

   4.1 Network Performance module collects the latency and packet loss data and automatically estimates a application-perceived latency for the user's references.

5. Fault management

   5.1 Automatic network fault diagnostic for you reference. It automatically detects and locates network faults by testing the connectivity between network nodes and inspecting DNS servers, and provides suggested solutions.

   5.2 Network diagnostic by probing routers on the route path and provide corresponding statistical information, based on mtr tool. Using these information, the location of network fault can be located more accurately.
