My Phone, The File Server

I'm cleaning out my room.

There's so much stuff that could make other people happier than it makes me. If anyone is interested in a variety of things, from fancy knapsacks to Tsum Tsums to dolls, let me know.

But that's not why we're here - We're here because I found my old Moto X phone. I'm not sure why I stopped using it, but I know I replaced it with the Galaxy S5 in 2014, and eventually my mother's hand-me-down LG Stylo until I dropped it and shattered the screen.



And receiving my own LG Stylo 2 this February. If I knew I still had my Moto, I wouldn't have paid money for an upgrade (Assuming it still works on T-Mobile's networks. It should).

So I found the article - What To Do With an Old Smartphone - And besides some usual suggestions - one stood out.

Make Your Phone into a File Server.

 I picked the app FTP Server - It opens the appropriate ports on the phone and grants file access. Of course, you could probably do it a different way without the help of a third party application.

And Lo and behold;




While the default port for FTP is 21, this one is using 2221. Why? I change it to 21 to see if it still works. It doesn't, so I turn it back.

Here are the settings on the application;







It seems that we can only pick one directory to work from at a time. I took a screenshot, placed it in the appropriate folder, and simply saved it from the "server"!


I can also enable a password and username to log in;

This is a private network, so no problems. But one could probably lure people to an open file server in a public place. How could I monitor hits? 



These are the interfaces the application can listen to. PAN and Wifi make sense, but how would outside connections come through on the Loopback? Does Mobile Data have a port to listen on?

Since the phone I'm using (The Stylo 1) Does not have access to the phone network, Mobile's a moot point anyway. I could install this on my active phone, but that doesn't seem smart. I don't do sensitive business on my phone to begin with, but why allow access?

So, why does this work? Because it's in a private network. It's using a private IP address, significant to our network only.

BUT....can I upload something to it from my Macbook?


I've never used the 'Go' option on my Macbook in the five years I've had it until today. 

I can connect to the server easily, using the IP address, port, and login creds.



So, I'll take this image;


And stick it somewhere on the server. Will it show up? 
There's not an upload option in the server settings, so no. But this was certainly a fun and informative thing to play with! 

I'll be sure to use this more in the future, if I can find an option with upload capabilities.

Wireless Diagnostics on Mac OS; Packet Sniffing on a WLAN

There's a post sitting in my drafts about Wireshark and how to sniff packets out of the air that was going to be about sniffing for authentication packets for Wi-Fi hotspots that aren't broadcasting SSID (Which you shouldn't do apparently! It's still not safe). I was watching this video to find a little more information about how to properly use Monitoring mode on my Macbook to sniff for WLAN packets on the network. So when he said "Just open up Wireless Diagnostics and sniff your network (check your width and channel)." It was shocking to me.
