================================================================================
|
|
RustNet 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 /usr/bin/rustnet
|
|
|
|
Expected output (Linux 5.8+):
|
|
/usr/bin/rustnet cap_net_raw,cap_net_admin,cap_sys_admin,cap_bpf,cap_perfmon=eip
|
|
|
|
Or for older kernels:
|
|
/usr/bin/rustnet cap_net_raw,cap_net_admin,cap_sys_admin=eip
|
|
|
|
If capabilities are not set, you can manually set them:
|
|
# For Linux 5.8+ with eBPF support
|
|
sudo setcap 'cap_net_raw,cap_net_admin,cap_sys_admin,cap_bpf,cap_perfmon+eip' /usr/bin/rustnet
|
|
|
|
# Or for older kernels
|
|
sudo setcap 'cap_net_raw,cap_net_admin,cap_sys_admin+eip' /usr/bin/rustnet
|
|
|
|
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.
|
|

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