+# respondd-crashed
+
+This tool ping every "offline" node at every ip address of a meshviewer.json to detect, if a respondd deamon is not running anymore.
+
+
+## give access to run ping
+```bash
+ sudo setcap cap_net_raw=+ep %GOPATH/bin/respondd-crashed
+```
+
+
+## Usage
+
+Usage of respondd-crashed:
+  -ll-iface string
+    	interface to ping linklocal-address
+  -loglevel uint
+    	Show log message starting at level (default 40)
+  -meshviewer-path string
+    	path to meshviewer.json from yanic (default "meshviewer.json")
+  -ping-count int
+    	count of pings (default 3)
+  -ping-timeout duration
+    	timeout to wait for response (default 5s)
+  -run-every duration
+    	repeat check every (default 1m0s)
+  -status-path string
+    	path to store status (default "respondd-crashed.json")
+  -timestamps
+    	Enables timestamps for log output
