how to close ports for ac56u?

[bobyang]

I have turned all the services off.. but I still see these are open. I just wonder how to turn them off? (I only want to keep 53, 443, and 22)

thanks!

You can't close everything down. Some of these are used by the printer sharing feature of the router, for instance.

I see. but I don't use printer feature so I cannot close it?

thanks to vt1431! very great info as following

optional:
to easy list used ports/files try optware/entware lsof utility:

lsof | grep IPv4 | sort | less

to get rid of unused usb printer try this:

nvram set usb_printer=0; nvram commit

and place in /jffs/scripts/services-start:

#!/bin/sh
service stop_lpd
service stop_u2ec
