Shell script for displaying RN 214 LCD messages
Hi everyone, I made a small ssh shell script for displaying texts on Readynas 214 (or 204) OS6.0.xx LCD Display (e.g. for messages of an end of a ssh shell programm). Have fun with it! Name it a...
hello StephenB,
I know you are here master, and we/me appreciate you all but listing all possible commands WHICH ARE DANGEROUSLY FOR THE NAS IS NOT VERY CONSTRUCTIVE. eg like firmware_update, start_raids are not that what surely anyone of Netgear wants, isn't it?
In my case I just wanted to give a little shell tool for infos on the LCD screen (the other ones I already knew, and beside of that I can "!hexray" and ghidra anything on RN...)
But anyway thanks to you for giving some bad peoples an idea to write trojans with firmwar_update

k as a command - and there are a lot more of these commands than show up in the help text.

start_raids is already referenced here, all that is new is that it is a soft link to rnutil. Folks from Netgear have previously posted the commands used to manually update the NAS flash from ssh.
I agree that playing with the commands w/o documentation is risky - though Sandshark and I both have NAS that we only use for exploration. Netgear could deny support if you damage your system with ssh.
But nothing I posted would give much help to a hacker. If they have a ReadyNAS (or download the free VM), then they can easily see all this stuff for themselves.
