Investigate command line tools on airos #25

Open edoput opened 7 years ago

edoput commented 7 years ago

The system configuration is kept in /tmp/system.cfg. Well, it's not really kept in there, it is stored in NVRAM and read into there on boot. There are command line tools for maniuplating this. They are all bound up in a multi-call binary called ubntbox, evidently a nod to busybox. The main interesting one is,

cfgmtd -- read and write the config to the NVRAM

So, for example, one thing that one might do is

vi /tmp/system.cfg
cfgmtd -w

to edit the config, and then write it to NVRAM

Once you have saved it you can reboot by issuing the “reboot” command or you can do a soft apply:

/usr/etc/rc.d/rc.softrestart save

Unfortunately it does still cut the user out of the antenna but it leaves a wonderful ouput
