Preface

You might have heard of the Reality protocol long ago. No domain, no certificate required, easy deployment, low cost. Many say it’s “low profile, safe, difficult to identify.” But why do you always get zero speed test results, instant disconnections, or handshake failures? Why in 2025 do many people still recommend this protocol? Do you know the real reasons behind handshake failures and zero speeds?

Video Demonstration

Do you really know how to configure Reality? Setup fails frequently, which 90% of people step into! Reality deployment full process!

Preparations

  1. One VPS, reinstalled with major operating systems; Debian 12 recommended. (VPS in this video demo is from BandwagonHost CN2 GIA, while budget users are advised checking Akkocloud)

  2. RealiTLScanner target website scanner Releases Page

  3. Reality protocol target website checking tool Releases Page

Finding Target Domains

Domain Conditions

Base terms:

  • Avoid using jumping domains (domains that complete with redirects).
  • Must support TLS 1.3
  • Must support X25519
  • Must support HTTP/2 (H2)
  • Must match SNI accurately

Bonuses:

  • Try avoiding nodes resting behind CDNs.
  • Try avoiding heavily populated pages.
  • Opt for small TLS handshake delay factors.
  • Close node IP (Check utilizing RealiTLScanner tool).

How to Locate Target Domains

Use the RealiTLScanner tool, scan VPS creating file.csv exports using commands below:

# macOS/Linux Commands
# If prompted damaged execution, run: sudo xattr -r -d com.apple.quarantine (target spec)
./RealiTLScanner -addr VPSIP -port 443 -thread 100 -timeout 5 -out file.csv 

# Windows Command (Terminal on Desktop):
cd "%USERPROFILE%\Desktop"
RealiTLScanner-windows-64.exe -addr VPSIP -port 443 -thread 100 -timeout 5 -out file.csv

Important Notes:

  • Run RealiTLScanner locally whenever possible, rather than on remote nodes.
  • Change output name inside consecutive runs to avoid overwrite failures: file1.csv, file2.csv, etc.

# Install latest
bash <(curl -Ls https://raw.githubusercontent.com/alireza0/s-ui/master/install.sh)

# Legacy ver, e.g. 1.0.0
VERSION=1.0.0 && bash <(curl -Ls https://raw.githubusercontent.com/alireza0/s-ui/$VERSION/install.sh) $VERSION

Setup panel UI

Important: If you haven’t applied for domains or certificates, avoid accessing via straightforward HTTP to mitigate exposure risks before SSL logs save successfully!

Establish remote encrypted tunnel setup first locally before configuring node sub tier controls:

ssh -L <local_port>:127.0.0.1:<remote_panel_port> <user>@<server_IP>
# E.g.: ssh -L 54321:127.0.0.1:55555 root@178.157.58.201

# For non-default SSH ports, e.g., 2222:
ssh -fN -p 2222 -L <local_port>:127.0.0.1:<remote_panel_port> <user>@<server_IP>

Enabling tunnel setups

When the shell echoes #, tunnel establishments succeeded.

Now visit absolute http://127.0.0.1:54321/55555 to setup. Keep tunnel sessions open while doing setup node modifications prior to SSL deployment completion fully securing directly buffers thereafter safely.

Afterword

Reality protocol is simple yet detailing. Advantage leans heavily on no-cert, no-domain setups deploying cleans and cleanly cleanly.

Amid TLS throttling environments today, Reality picking up destination TLS echoes acts definitively better obscuration than standard proxy masks. But improper targets or clock offsets trigger failures. Maintain small, un-CDN’d target spec buffers and access remotely via tunneled secured logic initially bypassing sniffing probes accurately smoothly.
