I did something dumb. I accidentally set my SSH server to port 80, where the web config also listens. Now I can't get into either.
Luckily, I still had the folder with my NFS exports file available from a network share. I exported my root directory, rebooted the router, and now have full file system access via NFS.
I guess I'm looking for a conf file or something where I can temporarily stop the SSH server from starting on boot so I can fix the ports. I also found "script_wanup.sh" and "script_init.sh" if there's a command I could add to kill the SSH server once its started.
