## Why The existing loopback listener mode does not provide the stdin/stdout transport needed by OpenSSH's `ProxyCommand`. ## What changed - Relay one SSH session over HTTP/3 CONNECT with `--environment-id ENV --port PORT`, defaulting to the public Portals gateway and port 22. Also accept an explicit `--proxy-url` with `--target ENV:PORT`. - Require ChatGPT OAuth login, enforce cloud configuration and application network policy, and restrict OAuth credentials to the built-in gateway origin. Leave SSH authentication and host-key verification to OpenSSH. - Preserve binary stdio, propagate input half-close, exit on gateway EOF, and report rejected CONNECT requests by HTTP status without exposing arbitrary peer error text. - Require ERS-issued v2 tunnel JWTs for Portals listener mode unless OAuth mode is selected, and reject older ERS tunnel JWTs during credential updates. - Disable UDP segmentation offload for SSH tunnels on Linux to avoid stalled bulk transfers on affected paths. Document an OpenSSH configuration example. ## Testing Add coverage for argument validation, gateway routing, credential boundaries, JWT startup and renewal checks, binary relay and half-close behavior, gateway EOF and rejection, and cloud policy enforcement before gateway connection.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):
curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh
$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; irm https://chatgpt.com/codex/install.ps1 | iex
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
