CODEGATE 2016: JS_is_not_a_jail

JS_is_not_a_jail
nc 175.119.158.131 1129

After connect the server, I try to "quit()" command.
It was occurred a error with the file path "/home/codegate/cg.js"

I can use a read() feature to read the code.

read('/home/codegate/cg.js')

FLAG:
easy xD, get a more hardest challenge!
