If the destination machine has disabled ping, what response is recieved?
- dec0dedab0de 2y agonothing from that machine, but the way the ttls work, it doesn’t affect the responses from routers along the way. Same if the destination doesn’t exist at all.
- mannyv 2y agoTotally untrue. Network admins will often disable traceroute responses because security. Edit: the less someone knows about your internal topology the better. Security through obscurity does work.
- ru552 2y ago~~ Security through obscurity does work. As a layer.
- Hikikomori 2y agoWindows disables ping by default for what I'm guessing is security.
- dec0dedab0de 2y agoI was answering a question about what happens if it is disabled on the destination machine. The destination machine has no say over any other device along the route.
- teddyh 2y ago“ping” is ICMP ECHO_REQUEST and ICMP ECHO_RESPONSE. Traceroute uses ICMP TIME_EXCEEDED. So blocking only “ping” will not affect traceroute. And if you block all ICMP, you break your own internet: <http://shouldiblockicmp.com/ http://shouldiblockicmp.com/>
- newman314 2y agoThe number of companies that I've encountered that wholesale block ICMP because "security" is painfully high.
