"Network is unreachable" error on Kali Linux on Virtual Box VM on Mac OSX
by EmileDiaz from LinuxQuestions.org on (#4W98T)
Hi all:
New to Kali Linux and this forum. I am running Kali on a VirtualBox on a mac laptop.
I'm unable to ping a url or an ip. I get either a ""Temporary failure in name resolution" or "Network is unreachable" when I try various network queries. Seems like I either don't have a proper DNS configured or something else perhaps
I am posting details of some basic info below that I did to see what the "/etc/hosts" and "etc/resolv.conf" files contain. Also I did some looking to see what the "ip a" or "ifconfig" bring up. Particularly worrisome was the" route -n" query (see below) which brought up nothing under the headings of "Destination" "Gateway" "Genmask" etc...That all looks wrong but I don't know enough to fix it.
When I try and set the ip of my router for eth0 is when I get the "network is unreachable" error.
Perhaps someone can read the details below and help.
Many thanks.
