AWS dcv: Update Linux client proxy settings and add SOCKS5 option

Service: dcv · 2026-10-15 · Documentation medium

File: dcv/latest/userguide/using-connecting-linux.md · Type: network

Summary

Rewrites the connection proxy configuration steps: renames options (None/System/SOCKS/HTTP/HTTPS), adds a SOCKS5 proxy option, and changes proxy authentication to an Authentication toggle with sign-in credentials.

Security assessment

The change documents proxy configuration including authenticated HTTP/HTTPS/SOCKS5 proxies and credential entry, which is security-adjacent network configuration guidance but does not address a specific vulnerability or incident.

Evidence

+     * To connect to the Amazon DCV server through a specific SOCKS5 proxy server, choose **SOCKS**. Specify the IP address or the hostname of the proxy server, as well as the communication port. If the proxy server requires authentication, toggle the **Authentication** switch and enter your sign-in credentials.
