Auto bras dial and dynamic DNS tool for Nanjing University

The network system of NJU has a mystery flow control mechanism. Some times it may be triggered and the bandwidth and visitable domains of a certain machine will be limited. The limitation can be bypassed by change a machine's MAC address. But if we do this, the auto-dial function of nju bras will not work (because it identifies a machine by it's MAC address). So I developed this tool to auto dial the bras to help you stay online even if you changed your mac address remotely (by RDC or some other tools).

It can also help you maintain a dynamic dns to your machine and notify something via tools like bark.

Usage

• prepare a config like template.yaml
• njuddns -c /path/to/your/config
• check the log

Modules

njubras: a bras dail/status query tool

    loginStatus, err := DoLogin(username, password)
    logoutStatus, err := DoLogout()
    err = AcquirePortalStatus()
}

TODO & Roadmaps

• Use new logging system to notify correctly
• Support more ddns and notify tools
• Support login via unified login of NJU
