Έτσι και εγώ έστησα ένα εικονικό δίκτυο με την χρήση Virtualbox Vms:
Στο Lubuntu vm έστησα ακόμη και έναν bind9 DNS Server με τις εξής ρυθμίσεις:
- named.conf:
- Κώδικας: Επιλογή όλων
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local
include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
//include "/etc/bind/named.conf.default-zones";
- named.conf.local
- Κώδικας: Επιλογή όλων
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
forwarders {
208.67.222.222;
208.67.220.220;
};
//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys. See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;
auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
acl "intranet" { 10.42.0.0/24; };
view "intranetView" {
match-clients { "intranet"; };
recursion yes;
zone "intranet.example.com" {
type master;
file "/etc/bind/db.intranet";
};
include "/etc/bind/named.conf.default-zones";
};
view "outside" {
match-clients { any; };
recursion no;
include "/etc/bind/named.conf.default-zones";
};
- Και όπως βλέπετε παραπάνω την ζώνη intranet.example.com στο αρχείο db.intranet:
- Κώδικας: Επιλογή όλων
$TTL 604800
@ IN SOA intranet.example.com. (
2 ; Serial
604801 ; Refresh
86400 ; Retry
241 ; Expire
604801 ) ; Negative Cache TTL
;
@ IN A 10.42.0.1
app1 IN A 10.42.0.1
app2 IN A 10.42.0.1
Δε το Lubuntu Vm έχει και τα εξής interfaces
- Κώδικας: Επιλογή όλων

Όμως όταν μπαίνω στο σε ένα VM και προσπαθώ να κάνω ping το intranet.example.com λαμβάνω:
Όμως μπορεί και κάνε resolve το google.com.
Έχετε ιδέα πως να το λύσω.
Ακόμη για την εφαρμογή αυτή μήπωςε θέλω και δεύτερο network interface στο Lubuntu vm μου;
