SOCKS5 Proxy Support in Network Sandbox

Entry
JSON All of v2.0.17
EntryKind: in v2.0.17,
ChangesSection of the release

What: Complete SOCKS5 proxy server added alongside existing HTTP proxy for enhanced network sandboxing on Linux and macOS. Provides dual-proxy infrastructure on ports 1080 (SOCKS) and 3128 (HTTP).

How to use: Automatic when network sandbox is enabled. The SOCKS proxy is configured via environment variables:

# Automatically set when sandbox is active
ALL_PROXY=socks5h://localhost:1080

Details:

  • SOCKS5 server implementation with authentication and connection filtering
  • Unix socket bridges for both HTTP and SOCKS proxies on Linux (claude-socks-.sock, claude-http-.sock)
  • Environment variables automatically configured: ALL_PROXY, all_proxy, GIT_SSH_COMMAND, FTP_PROXY, GRPC_PROXY, etc.
  • Function QJ6() wraps commands with dual proxy setup using socat
  • Parallel initialization of both proxy servers in HJ6()
  • Evidence: QJ6() at line 207609, Bp2() at line 207346, KJ6() and HJ6() at line 207225 in v2.0.17 (SOCKS functionality completely absent from v2.0.15; only HTTP proxy existed)
