Just got 2 antminers today, SSH'd into them, typed in "vi etc/config/cgminer" and added "option api_allow 'W:0/0" on a new line. Saved the file, rebooted the antminer and now etc/config/cgminer appears to not exist whenever I try to open it up again on both antminers. Resetting the antminer does not fix this.

Any ideas what I can do?
