file-proxy-monitor

File and Proxy Monitor is an independent open-source Linux desktop workbench
combining a real dual-pane filesystem manager with live socket inspection and
proxy diagnostics.

Key Features:
- Dual-Pane Filesystem Manager (Tab 0): Browse real local and removable-media
directories side by side, copy, move, rename, create directories, delete
with confirmation, compare directory contents, and verify SHA-256 digests.
- Live Kernel Socket Table Reader (Tab 1): Inspect active IPv4/IPv6 TCP and
UDP endpoints directly from Linux kernel procfs tables with local/remote
addresses, ports, connection states, UID, socket inode, queue counters,
live filtering, and CSV export.
- HTTP CONNECT & SOCKS5 Proxy Latency Tester (Tab 2): Measure real TCP
connect time, HTTP CONNECT or SOCKS5 handshake latency, and total roundtrip
duration over real sockets, with optional Basic / RFC 1929 authentication.
- Local TCP / HTTP / SOCKS5 Relay Listener (Tab 2): Bind a local listener on
loopback 127.0.0.1 to accept HTTP CONNECT, plain HTTP, SOCKS5, or TCP port
forwarding sessions while logging real proxied TX and RX byte counters.
- Bilingual English (default) and Vietnamese UI with instant switching.
