  • Using ssh-keygen to generate key pair to get fringerprint.
  • Note your key's fingerprint to use later. Fingerprint look like: SHA256:07jcXlJ4SkBnyTmaVnmTpXuBiRx2+Q2adxbttO9gt0M.
ssh-keygen

  • Create a CNAME point to serveo.net.
  • For each SSH key to allow, a TXT record at _serveo-authkey.[domain] = [fingerprint].

Step 3

  • Request your subdomain/domain from serveo.
ssh -R subdomain.example.com:80:localhost:3000 serveo.net
