Usage: wgctl watch [options]
|
|
|
|
Live monitor of WireGuard activity.
|
|
- Handshakes from connected peers (green)
|
|
- Connection attempts from blocked peers (red)
|
|
- Firewall drops from restricted peers (red)
|
|
|
|
Options:
|
|
--name <name> Filter by client name
|
|
--type <type> Filter by device type
|
|
--blocked Show only blocked peer attempts
|
|
--allowed Show only handshakes
|
|
--restricted Show only firewall drop events
|
|
--raw Show raw IPs without host/service resolution
|
|
|
|
Examples:
|
|
wgctl watch
|
|
wgctl watch --name phone-nuno
|
|
wgctl watch --blocked
|
|
wgctl watch --type phone
