Description

Long transfers with no activity may get dropped by firewalls/NATs. There is no keep-alive message in the protocol.

Location

src/shared/protocol.h (NEED STATUS enum)

Suggested Fix

Add STATUS_KEEPALIVE to the NET_STATUS enum. Sender sends it periodically during long chunk transfers; receiver resets its timeout on receipt. Frequency should be configurable (default: every 30s of inactivity).

Severity

medium
