I need to configure port forwarding, perhaps?

Forwarding port 8333

To have a fully functional Bitcoin node, you need to forward incoming connections on port 8333 to the device running Bitcoin core.

We first assign a static local IP to our bitcoin core host, e.g., 192.168.1.201, then we create a forwarding rule to that host for all incoming connections on port 8333.

I use pfSense, and this is my config for a static IP. Consult online to accomplish this on your router.

Where is the conf file for bitcoin-core? The wiki says to check: /home/username/.bitcoin/bitcoin.conf

But I see:

How do I run bitcoin-core in prune mode? And, where is the conf file?

The GUI:

bitcoin

But I'm just looking to use the console, and have no need, nor space, for the blockchain. Never mind the bandwidth.

You can follow this guide.

Pretty straight forward response to what you are looking for. :)

Here is a copy of that reference, in case the website is not available anymore in the future:

Bitcoin Core Daemon

If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (This can be a locked account used only by Bitcoin Core.) If you changed users in a graphical interface, start a terminal.

Type the following command:

bitcoind -daemon

It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface).

Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:

error: {"code":-28,"message":"Verifying blocks..."}

After it starts, you may find the following commands useful for basic interaction with your node: getblockchaininfo, getnetworkinfo, getnettotals, getwalletinfo, stop, and help.

For example, to safely stop your node, run the following command:

bitcoin-cli stop

A complete list of commands is available in the Bitcoin.org developer reference.

When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several days, and it may take much more time on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.

Optional: Start Your Node At Boot

Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab on most distributions, run the following command:

crontab -e

Scroll to the bottom of the file displayed and add the following line:

@reboot bitcoind -daemon

Save the file and exit; the updated crontab file will be installed for you. On most distributions, this will cause Bitcoin Core daemon to be automatically started each time you reboot your computer.

Well, I clicked "prune":

bitcoin

and clicking "edit configuration file" brings up gedit with file and path:

nicholas@mordor:~$ 
nicholas@mordor:~$ cat snap/bitcoin-core/common/.bitcoin/bitcoin.conf 
#test
nicholas@mordor:~$

not sure how that helps me run bitcoin-core from the console, however.

This is an old question, but still. I found that the location of the bitcoin-core run file is:

/var/lib/snapd/desktop/applications/bitcoin-core_bitcoin-qt.desktop

In this file I found the command:

Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapdesktop/applications/bitcoin-core_bitcoin-qt.desktop /snap/bin/bitcoin-core.qt %u

So I just put this line into my /home/.bashrc file:

alias bitcoin-core='env BAMF_DESKTOP_FILE_HINT=/var/lib/snap/desktop/applications/bitcoin-core_bitcoin-qt.desktop /snap/bin/bitcoin-core.qt %u'

After restarting the terminal, the command works fine:

neobliz1@us:~$ bitcoin-core
