I have a problem. So, when I connect to any wi-fi station I can't use google or yandex. I solved that. The thing was in dns. I added google dns servers to 'resolv.conf' and it worked fine. However, after reconnection it does the same thing and I have to write manually or with script to set dns.
Is there any way to make this process automatically when the computer connects to the network? I tried to do it through the network/interfaces post-up and if-up.d . But it didn't help. The code is like that.

interfaces:

auto wlan0
 iface wlan0 inet dhcp
 post-up /etc/network/ssh_and_dns_start

ssh_and_dns_start:

#!/bin/sh

add_dns()

echo "nameserver 8.8.8.8
nameserver 8.8.4.4" >> /etc/resolv.conf


add_dns
exit 0

Try adding this to /etc/dhcp/dhclient.conf

interface "wlan0"
 supersede domain-name-servers 8.8.8.8, 8.8.4.4;

The way I did it was hackish and probably not the way you would want to do it, but if you just need the bleeping thing working...

So I had set up Kali connected to ethernet and when I went to add a wifi connection, no DNS. /etc/resolv.conf pointed to something like /run/resolvconf/... which pointed to yet another thing.

There's not the option to sudo yourself and vim /etc/resolv.conf - for a few reasons. So logout, login as root, delete the symlink /etc/resolvconf/... points to, then vim /etc/resolv.conf and add the nameservers you want, e.g.

nameserver your.gateway.ip

or

nameserver 8.8.8.8
nameserver 8.8.4.4

Before this, you can try

root@kali# dhclient wlan0

to get some information. I didn't find it very helpful. Editing the wireless connection settings with the GUI didn't work for me, even though it picked up on the nameservers. I just went ahead and deleted the symlink for /etc/resolv.conf and created /etc/resolv.conf, and all was fine.
