I'm trying to "hide" the fact that SSH + deluge are running when port scanned. I think my options are I can firewall the server, open SSH port and keep it visible, and get to the deluge by going to localhost:8112 after a ssh -D $someport. Or, I can use knockknock and hide SSH and Deluge but need to keep 1outbound+1inbound tcp port open for deluge xfers (or use knockknock-proxy). - Server(s) running Ubuntu 10.10 --> 12.04 - knockknock --> http://www.thoughtcr...are/knockknock/ - SSH - deluge-torrent.org/ 1. Has anyone on the forums attempted to setup port knocking with knockknock before? 2. Am I correct in assuming that it would be wise to NOT use UFW to configure my firewall and instead rely strictly on iptables? I believe this to be true because knockknock will need custom iptable entries to work. 3. SSH seems simple to think through. Knock on one port and connect. All Inbound+Outbound traffic flows over one port after the connection is established -- easy enough. 4. I threw in an application like Deluge because I can't get my head around the firewall logic. "deluged" runs as a local daemon on the server. Once a Torrent is added it needs two ports to operate (1 Inbound + 1 Outbound). "deluge-web --fork" is a web gui to add/remove Torrents. It runs on a separate port (8112 by default), for a total of three. My best guess is to create a knockknock rule for the web gui (8112) and leave deluge's inbound (5000) + outbound (6000) ports open and standard SSH knockknock rule. OR should I use the knockknock-proxy? Can anyone contribute/comment on how this should be setup? THANKS
