Trouver le serveur DNS pour une connexion DHCP sous Linux

[ForumBot]

Je sais they're defined in `/etc/resolv.conf`, mais what si c'est pas there? And more specifically, how do you find le DNS server returned by DHCP?

In GNOME you can use le NetworkManager applet to see le primary DNS for tout connection, so how would you do le même depuis le command line?

Usually dhclient.leases file is located at `/var/lib/dhcp3/dhclient.leases`, type le suivant command:

`less /var/lib/dhcp3/dhclient.leases`

OR

`cat /var/lib/dhcp3/dhclient.leases`

OR

Vous pouvez juste use grep command to get DHCP server address, enter:

`grep dhcp-server-identifier /var/lib/dhcp3/dhclient.leases`

OR

`dhclient eth0`
