Amazing, i just found the setting in the config of my web installation. I was looking for a file to edit.
Now i have changed it to /sbin/ping and now i don't get anymore errors, but if i clear a subnet and readd it, and rescan it, it still shows every client als "Online". If i scan one client if it's available, it tells me it's offline, but keeps the green dot on the left side to the IP... Shouldn't that one get red if there is no client occupying that IP? Or did i get something basic wrong?
