Hello, I want to use "ip route get" to get the next hop ip, but I get the following error: RTNETLINK answers: Invalid argument my command line is: ip route get from 1.2.3.4 to 192.168.1.1 iif eth0 If I use: ip route get 192.168.1.1, it succeeded. I don't know why it failed when I add "from" and "iif" option. Please give me a hand. Thanks a lot.
