Hi all,

so I have installed vsftpd on my Debian Buster system, now I want to check my IP address and it gives the following: XXX.X.X.1/8. I believe this refers to localhost IP address on my computer.

No I want to connect from Android phone using AndFTP application, but when you add Hostname as your local IP address as describer above, it fails.

I am using standart Virgin Media Hub 3.0 here in UK, but the question is can I even connect through this hub to my localhost PC with anFTP application or do I have to provide an IP address of the router itself?

Is it even possible and how do I get that hubs IP address whilst using Linux terminal?

Thank you

1. You should be using sftp and not ftp especially over the internet. andFTP supports sftp protocol which is ssh.

2. If you want to connect to your PC over the internet you need to forward ssh port in the hub.

3. There are many ways to find your public IP address. Just Google it.

4. There are free dynamic DNS sites so you can have the same URL regardless if your public IP address changes.

I second the recommendation to drop FTP and stay with SFTP. For that, uninstall vsftpd and install openssh-server. Then you will have SFTP support on your server and can then adjust it to work with keys.

Then once you can log in from Android using SFTP with keys over the LAN, forward port 22 on your router (or another external port) to your server's port 22.

Some reasons to stay with SFTP is that SFTP is very easy to set up and requires only one port be opened and forwarded from your router. FTP, on the other hand, requires various random per-connection ports to be opened. Even experienced system and network adminstrators find FTP difficult. So, if you're stuck at this stage with FTP, please cut your losses and upgrade to SFTP. You'll save many hours of wasted effort as well as prevent your system from becoming a pushover for attacks.

Wow, easier than I thought (still beginner though), thank you guys.

Now, I have installed sshd server thanks to manual, however:

1) So I cd to /etc/ssh/ and then edit sshd_config and add "Port 2222", so It wont block any existing ports.

And then check the existing ports with netstat -tulpn, so I can seee Active Internet Connections, but all I see is port 22 within tcp and tcp6.

Why I do not see the port 222 based on changes in sshd config?

Should the newly set port be active even if I changed "ListenAddress" value to my current instead of default?

2) I will try to connect using: ssh -p 2222 username@ip

And It returns Connection Refused..

And even if I restart sshd I can still see active port 22, but not 2222

What am I doing wrong and how to establish new ports connection?

Thank you all,

Every PC with tcp/ip networking has a localhost virtual network adapter with the same IP address i.e IPv4 127.0.0.1 or IPv6 ::1. No need for obfuscation. This allows networking applications to connect to clients on the same computer regardless of an active physical network.

What address did you use for the ListenAddress?

The first step is to check to see if ssh works on the computer itself. ssh -p 2222 username@localhost

If that works you can try connecting from your phone using the systems LAN address. If you look at the output of the ip a command you will see something like
2. enp0s25: ...
...
inet xxx.xxx.xxx.xxx

That inet address is your LAN IP address. Assuming your phone is connected to your LAN use ssh -p 2222 username@xxx.xxx.xxx.xxx
