Using a custom domain

What you will need:

• a domain
• the ability to edit DNS records for that domain

First, you need to get your key's fingerprint:

ssh-keygen -l

The output should be something like: 2048 SHA256:YOUR_FINGERPRINT COMMENT (RSA)

Copy the entire string.

Next, add the DNS records (replace YOUR_SUBDOMAIN with the subdomain you want to use):

• Name = YOUR_SUBDOMAIN, Type = A, Value = 159.89.214.31
• Name = YOUR_SUBDOMAIN, Type = TXT, Value = authkeyfp=SHA256:YOUR_FINGERPRINT

Run it:

serveo http -d YOUR_SUBDOMAIN.YOUR_DOMAIN.com
