I have installed vsftpd and configured it for a simple ftp on extended storage on my Netgear R7500v2 router. I can only get the process to startup properly when NOT in standalone mode. In standalone I get an error "500 OOPS: could not bind listening IPv4 socket" when loading. However, I cannot specify an ip address and port for listening unless I use stand alone.
I've seen google references to this error when running xinetd, but I'm not running that or anything else that would appear to conflict with the binding the socket. Interested in any help on this ftp. I chose it because it was supposed to be easy, but can't find any good documentation as it relates to LEDE.
