The mobile broadband is used as a fallback, when the wired connection is unavailable. That works fine using standard ping. However the wired connection isn't under my control and somtimes there's a firewall there, blocking everything except of HTTP traffic.\r\n\r\nSo I tried to use httping. With httping as a tracking method the interface state is detected as online, as long the connection is available. When the connection is disconnected, the interface state goes to offline. But when the connection is working again, the interface won't go online.\r\n\r\nTest output in that state, on a network where both http and ping are allowed:\r\n```\r\nroot@charlie-wlan:~# ifconfig\r\n...\r\neth1      Link encap:Ethernet  HWaddr ...\r\ninet addr:10.31.0.217  Bcast:10.31.0.255  Mask:255.255.255.0\r\n...\r\n\r\nroot@charlie-wlan:~# ping -I eth1 1.1.1.1 -c 1\r\nPING 1.1.1.1 (1.1.1.1): 56 data bytes\r\n64 bytes from 1.1.1.1: seq=0 ttl=56 time=9.875 ms\r\n--- 1.1.1.1 ping statistics ---\r\n1 packets transmitted, 1 packets received, 0% packet loss\r\nround-trip min/avg/max = 9.875/9.875/9.875 ms\r\n\r\nroot@charlie-wlan:~# httping -y 10.31.0.217 1.1.1.1\r\nPING 1.1.1.1:80 (/):\r\nconnect time out\r\n```\r\n"}}
