Echo'ing into a file only works with root and not sudo












0















I have a directory /sys/class/leds/ with the file bananapro:green:usr/trigger that controls an (green) onboard led. The contents of this file just contains the modes for the led. As root, I can run echo "default-on" > /sys/class/leds/bananapro:green:usr/trigger and have the led turn on. If I try to do this from a different user, I get the following responce from bash;



bash: /sys/class/leds/bananapro:green:usr/trigger: Permission denied


I have tried also running using



sudo bash -c echo "<command>"


from the non root user (with sudo access)
Any recommendations on getting file permissions for users other than root
I do apologize in advance for my horrid formatting






permissions sudo root echo

My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
