Bind: Can you configure multiple domains using the same nameserver
Can you add multiple domains to a nameserver without creating a new IP address? I have one IP address on my machine and have configured forward and reverse zone files. Names are resolving fine.
I know I can add another domain to the named.conf file and create new forward and reverse files. what name server IP would i add to the forward file for the second domain and how is it configured in the forward file? Also I have named my reverse file with the reverse of the first 3 octets of my system IP address. I need to change that and what should i use for the reverse zone names?
Code:
named.conf:
zone "myserver.com" {
type master;
file "fwd.myserver.com.db";
allow-update { none; };
};
zone "xx.xx.xxx.in-addr.arpa" {
type master;
file "xx.xx.xxx.db";
allow-update { none; };
};
zone "newdomain.com" {
type master;
file "fwd.newdomain.com.db";
allow-update { none; };
};
/var/named:
cat fwd.myserver.com.db
$TTL 86400
@ IN SOA nameserver.myserver.com. root.myserver.com. (
10030 ;Serial
3600 ;Refresh
1800 ;Retry
604800 ;Expiry
86400 ;Minimum TTL
)
; Name Server
@ IN NS nameserver.myserver.com.
;A Record Definitions
nameserver IN A xxx.xx.xx.xx
server1 IN A xxx.xx.xx.xx
server2 IN A xxx.xx.xx.xx
How do I configure the forward zone record for the newdomain? i have used the one system IP address for the name server in the myserver.com domain.
Hello,
I have 3 domains virtually hosted "name based" the first one "domain1.com" has its ServerName entered as domain1.com. this domain will load in a browser by www.domain1.com or simply domain1.com. the next two domains "domain2.com" and "domain3.com" ServerNames are listed as domain2.com and...

Hello all. I'm hoping you can help with a problem I'm having with Samba. I have Samba running on a Solaris host.

Dear all,
I've not a good starting point I'm afraid, but I was forced to deploy Samba under pressure of failing hardware so an urgent migration was done. We didn't get the IBM AIX 6.1 supplied one running at all, so we pulled down the samba.org version 3.4.3. We couldn't get that working as... (0 Replies)

unbound
unbound(8) unbound 1.5.1 unbound(8)NAME
unbound - Unbound DNS validating resolver 1.5.1.
SYNOPSIS
unbound [-h] [-d] [-v] [-c cfgfile]
DESCRIPTION
Unbound is a caching DNS resolver.
It uses a built in list of authoritative nameservers for the root zone (.), the so called root hints. On receiving a DNS query it will ask
the root nameservers for an answer and will in almost all cases receive a delegation to a top level domain (TLD) authoritative nameserver.
It will then ask that nameserver for an answer. It will recursively continue until an answer is found or no answer is available (NXDO-
MAIN). For performance and efficiency reasons that answer is cached for a certain time (the answer's time-to-live or TTL). A second query
for the same name will then be answered from the cache. Unbound can also do DNSSEC validation.
To use a locally running Unbound for resolving put
nameserver 127.0.0.1
into resolv.conf(5).
If authoritative DNS is needed as well using nsd(8), careful setup is required because authoritative nameservers and resolvers are using
the same port number (53).
The available options are:
-h Show the version and commandline option help.
-c cfgfile
Set the config file with settings for unbound to read instead of reading the file at the default location,
/var/unbound/unbound.conf. The syntax is described in unbound.conf(5).
-d Debug flag: do not fork into the background, but stay attached to the console. This flag will also delay writing to the log file
until the thread-spawn time, so that most config and setup errors appear on stderr. If given twice or more, logging does not switch
to the log file or to syslog, but the log messages are printed to stderr all the time.
-v Increase verbosity. If given multiple times, more information is logged. This is in addition to the verbosity (if any) from the
config file.
SEE ALSO unbound.conf(5), unbound-checkconf(8), nsd(8).
