%description
A cross-platform network monitoring tool built with Rust. RustNet provides
real-time visibility into network connections with detailed state information,
connection lifecycle management, deep packet inspection, and a terminal user
interface.

Features include:
- Real-time Network Monitoring for TCP, UDP, ICMP, and ARP connections
- Deep Packet Inspection (DPI) for HTTP/HTTPS, DNS, SSH, and QUIC protocols
- Connection lifecycle management with protocol-aware timeouts
- Process identification and service name resolution
- Cross-platform support (Linux, macOS, Windows, BSD)
- Advanced filtering with vim/fzf-style search
- eBPF-enhanced process detection (enabled by default with automatic fallback)

================================================================================
RustNet %{version} has been installed with eBPF support!

NETWORK PACKET CAPTURE PERMISSIONS:
  RustNet requires specific Linux capabilities for packet capture and eBPF
  process detection. These have been automatically set if setcap is available.

  To verify permissions are set correctly:
    getcap %{_bindir}/rustnet

  Expected output (modern Linux 5.8+):
    %{_bindir}/rustnet cap_net_raw,cap_bpf,cap_perfmon=eip

  Or for legacy kernels (pre-5.8):
    %{_bindir}/rustnet cap_net_raw,cap_sys_admin=eip

  If capabilities are not set, you can manually set them:
    # For modern Linux 5.8+ with eBPF support
    sudo setcap 'cap_net_raw,cap_bpf,cap_perfmon+eip' %{_bindir}/rustnet

    # Or for legacy kernels without CAP_BPF support
    sudo setcap 'cap_net_raw,cap_sys_admin+eip' %{_bindir}/rustnet

  Note: RustNet uses read-only packet capture (no promiscuous mode).
        CAP_NET_ADMIN is NOT required.

  Alternatively, run rustnet with sudo:
    sudo rustnet

  eBPF FALLBACK:
    If eBPF fails to load, rustnet will automatically fall back to procfs-based
    process detection. Check the TUI Statistics panel to see which detection
    method is active.

  For more information, see the documentation at:
    %{_docdir}/%{name}/README.md

USAGE:
  rustnet              # Start network monitoring
  rustnet --help       # Show all options
