Pfsense ssh

These serve two purposes. First, they encrypt your data and prevent Man-in-the-middle attacks, and secondly, they verify that the site you visit is the site it claims to be. I used to think that the former was more important, but now I am more of the opinion that identity verification is most important, now that phishing attacks are commonplace.

LetsEncrypt has recently stepped in to help solve this problem. With this in mind, when I saw that my UniFi controller was marked:.

For a long time, certificates have been sold by certificate authorities, but now you can get them for free from LetsEncrypt. However, there are some provisos to be aware of. First while you used to be able to get a 3 year certificate from a vendor, LetsEncrypt certs are 90 days, and must be renewed.

Secondly, you have to be able to prove you control the name that the certificate is for. This makes things more complicated.

In effect, you either need to be able to prove you control the DNS entry of your server, or the server itself. Fortunately, pfSense makes this reasonably easy. Essentially, you create a dns entry for the server behind the firewall you want:. And I made this a cname that points to my firewall server.

LetsEncrypt expects to find an HTTP server there on port 80, and it wants to see a secret on that server to show that the requester, DNS owner, and server owner are all the same. LetsEncrypt will only let you do 5 calls per hour, so they have a staging environment that allows building and testing your solution.

When the key icon becomes a check, you are ready to ask for a certificate. These will enable your renewal, and the extraction of the certificates to a folder so you can easily move them to another server.

After you do something like this, I recommend an external port scan to check that you are still secure. If there is block that looks like:. Now that you have them, you need to get them to the server where the controller is. Doing this requires the following steps:. Aside from a bit of scripting skill my scripts are definitely roughwe need a trusted user that can connect from the pfSense server to the internal server in order to copy the file.

Enter passphrase empty for no passphrase : Enter same passphrase again:. Set ownership and permissions: the user needs to own those files, and the directory has to be globally executable, and the authorized keys has to be globally readable.

This lets the ssh service see them:. First, you will need the copier user to be able to use sudo with no password to only execute one command, so execute:.

This will use ssh to authenticate with your private key and run the command remotely. It should complete, and your unifi controller should still work.

I will run Putty Generator and change the Number of bits in it to make the key harder to crack. So I will put bits instead of I will click on Generate and move my mouse within the putty generator window until the key is generated.

You will have to keep moving your mouse cursor within this window in order for this bar to finish generating your key. Then Now I will save both Public and private key in a folder for my own use. Click Yes and continue then type the Username that I setup and the passphrase that you set it up. I am going to try and show the network configuration by typing Ifconfig ….
