Networking Woes

Postby figroll » 2013-09-13 12:22

Hi guys, first post here, been scouring the FAQ's and general bits and got pretty much used to debian now, I've tried Ubuntu, Fedora and Cent OS and find debian the best (I know Ubuntu is debian based but a load more differences).

So i'm at home with the system, been using this for around 6 months now I can, configure apache, ssh, webmin, samba, proftpd, phpmyadmin, mysql and run terminal via putty. One thing I'm slightly confused about is describing bind9. What I aim to do is run the server on the network currently 192.168.0.160, hit that in the address bar here's apache and a few projects i'm working on, all good, but further to that I am currently assigning ip's in my hosts file so 192.168.0.160 site1.lan etc. As you know things change, I am very organised and even have a second root mimicking exactly how my online webserver is to simply transfer the files over, update the database move on.

So far so good, but ideally instead of as you know constantly updating the hosts file I am aware of bind, further more I want control over the a records and more importantly mx which I have attempted. bind setup, test.lan assigned to ip 192.168.0.160, cmd in windows ping test.lan nothing, dig test.lan throws up:

Code: Select all
root@dns:~# dig test.lan

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> test.lan
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 56988

;; SERVER: 8.8.8.8#53(8.8.8.8)
;; WHEN: Fri Sep 13 12:02:26 2013
;; MSG SIZE  rcvd: 101


To be fair as new to bind9 unsure what that is actually saying at a guess nothing has worked however. So further to this, this is how I want to play it really and if you don't mind me asking some questions:

1. I do not want to make this available outside the lan so no need for google, opendns servers.
2. Where does the server reside? I'm connected into the router a not so good sagem sky default, dns ip range going upto .100
3. How do I build the bridge for the network to connect?

I am very willing to learn this, let's call it the last piece of the puzzle to the perfect home office web testing lan!

Thanks in advance :D

I confess I still don't know what your question is.

That said, some random thoughts that may or may not prove helpful...

BIND for a local DNS server is like a piano for a paperweight. Effective enough, but massive overkill. If all you are looking to do is run a local DNS server, DNSMasq does the job very nicely, and is vastly easier to configure. There is a bit of a learning curve, but the docs are exemplary.

Your local DNS server is a local machine. Where else would it be?

Based on the error your posted, it looks as if your local machine(s) are unaware of your local DNS server. So I'm guessing that at least part of your issue is incorrectly configured DHCP, and has nothing to do with DNS/BIND/whatever.

Thanks for the reply, confusing post yes I agree!

Well I've made a development, the dns is on 192.168.0.160 server, I've now pointed my configuration in windows to use this as the preferred server, created a virtual host in apache and it is loading, ping in cmd is receiving packets.

DNSmasq was running on my router into another router but I wanted to pull this out of the equation, does DNSmasq support MX records? I need to test out email server configurations and internal imap mail from the sites contact forms etc, hence, my choice of bind, plus, getting into bind would bypass hiding behind the fact of its complex layout and setup so I thought go for the worst case scenario?

Again thanks for the response

Sure, I'll do your searching for you.

Here you go. https://www.startpage.com/do/search?cmd ... 3F&cat=web

Well that is interesting, sorry for the inconvinience I should have gave it a search myself, it's one of those things where you write it and think what did I just write there?

You've been more than helpful, see what I come up with now :D

Thanks again and apologies for being lazy there.

It seems DNSmasq is not as effective, I again point the network to the DNS server but it would not ping however nslookup did ping back results but on the local ip. So changes made and it still did not work for some reason. Bind however is, I'm surprised at my findings so far, Overhaul absolutely however if I stick with plan A to get to grips with the more complicated software is that a bad thing.

So back again, Bind sort of works however in dig there is no answer. This is my setup and perhaps I'm doing something wrong with the "bridge" (connecting the network together).

Desktop Pc >>> wireless router (192.168.0.5) - static
Raspberry Pi >>> wireless router (192.168.0.160) - static

Desktop Pc (Windows 7) > using preferred dns server 192.168.0.160 > Debian 7 running on raspberry with webserver.

Ping cannot find "test.lan" on the following config:

Code: Select all
# Configuration file for dnsmasq.
#
# Format is one option per line, legal options are the same
# as the long options legal on the command line. See
# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.

# Listen on this specific port instead of the standard DNS port
# (53). Setting this to zero completely disables DNS function,
# leaving only DHCP and/or TFTP.
#port=5353

# The following two options make you a better netizen, since they
# tell dnsmasq to filter out queries which the public DNS cannot
# answer, and which load the servers (especially the root servers)
# unnecessarily. If you have a dial-on-demand link they also stop
# these requests from bringing up the link unnecessarily.

# Never forward plain names (without a dot or domain part)
#domain-needed
# Never forward addresses in the non-routed address spaces.
#bogus-priv


# Uncomment this to filter useless windows-originated DNS requests
# which can trigger dial-on-demand links needlessly.
# Note that (amongst other things) this blocks all SRV requests,
# so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.
# This option only affects forwarding, SRV records originating for
# dnsmasq (via srv-host= lines) are not suppressed by it.
#filterwin2k

# Change this line if you want dns to get its upstream servers from
# somewhere other that /etc/resolv.conf
#resolv-file=

# By  default,  dnsmasq  will  send queries to any of the upstream
# servers it knows about and tries to favour servers to are  known
# to  be  up.  Uncommenting this forces dnsmasq to try each query
# with  each  server  strictly  in  the  order  they   appear   in
# /etc/resolv.conf
#strict-order

# If you don't want dnsmasq to read /etc/resolv.conf or any other
# file, getting its servers from this file instead (see below), then
# uncomment this.
#no-resolv

# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
# files for changes and re-read them then uncomment this.
#no-poll

# Add other name servers here, with domain specs if they are for
# non-public domains.
#server=/localnet/192.168.0.1

#******************************************************************
# these are google's domain name server. OpenDNS is an alternative
# and there are others if you don't want to use google.
server=8.8.8.8
server=8.8.4.4
#******************************************************************

# Example of routing PTR queries to nameservers: this will send all
# address->name queries for 192.168.3/24 to nameserver 10.1.2.3
#server=/3.168.192.in-addr.arpa/10.1.2.3

# Add local-only domains here, queries in these domains are answered
# from /etc/hosts or DHCP only.
#local=/localnet/

# Add domains which you want to force to an IP address here.
# The example below send any host in double-click.net to a local
# web-server.
#address=/double-click.net/127.0.0.1

# --address (and --server) work with IPv6 addresses too.
#address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83

# You can control how dnsmasq talks to a server: this forces
# queries to 10.1.2.3 to be routed via eth1
# server=10.1.2.3@eth1

# and this sets the source (ie local) address used to talk to
# 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that
# IP on the machine, obviously).
# server=10.1.2.3@192.168.1.1#55

# If you want dnsmasq to change uid and gid to something other
# than the default, edit the following lines.
#user=
#group=

# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
interface=eth0
interface=wlan0
# Or you can specify which interface _not_ to listen on
#except-interface=
# Or which to listen on by address (remember to include 127.0.0.1 if
# you use this.)

#********************************************************************
listen-address=127.0.0.1
listen-address=192.168.0.160
#********************************************************************

# If you want dnsmasq to provide only DNS service on an interface,
# configure it as shown above, and then use the following line to
# disable DHCP and TFTP on it.
#no-dhcp-interface=

# On systems which support it, dnsmasq binds the wildcard address,
# even when it is listening on only some interfaces. It then discards
# requests that it shouldn't reply to. This has the advantage of
# working even when interfaces come and go and change address. If you
# want dnsmasq to really bind only the interfaces it is listening on,
# uncomment this option. About the only time you may need this is when
# running another nameserver on the same machine.
#bind-interfaces

# If you don't want dnsmasq to read /etc/hosts, uncomment the
# following line.
#no-hosts
# or if you want it to read another file, as well as /etc/hosts, use
# this.
#addn-hosts=/etc/banner_add_hosts

# Set this (and domain: see below) if you want to have a domain
# automatically added to simple names in a hosts-file.

#*******************************************************************
expand-hosts
#*******************************************************************

# Set the domain for dnsmasq. this is optional, but if it is set, it
# does the following things.
# 1) Allows DHCP hosts to have fully qualified domain names, as long
#     as the domain part matches this setting.
# 2) Sets the "domain" DHCP option thereby potentially setting the
#    domain of all systems configured by DHCP
# 3) Provides the domain part for "expand-hosts"
#domain=thekelleys.org.uk

# Set a different domain for a particular subnet

# Same idea, but range rather then subnet
#domain=reserved.thekelleys.org.uk,192.68.3.100,192.168.3.200

# Uncomment this to enable the integrated DHCP server, you need

have you tried setting domain to just test.lan and then setting test.lan 192.168.0.160 in /etc/hosts?

looks complicated, machine running dnsmasq has address/domain inside dhcp range

if you can't ping, might be a firewall on the router, it's probably easier to setup basic connectivity first, and then dnsmasq and other stuff but I do it backwards a lot of times too,

Your dig is querying google, not your own server.

Even if it was ...
figroll wrote:

# Add local-only domains here, queries in these domains are answered

you don't have test.lan set as a local domain.

figroll wrote:interface=eth0
interface=wlan0
#listen-address=127.0.0.1
listen-address=192.168.0.160

Here you have told it to listen on two interfaces, but then restricted it to one IP address.

Also, you have set test.lan to be the domain name appended to hostnames in the specified subnet (which is generally unnecessary unless you have multiple subnets you want to differentiate by name).

If you are expecting test.lan to resolve to a host, where have you set that?

Thanks for the replies, networking wise I'm new to this thanks for the patience.

So if i remove googles DNS servers that will just query the LAN? (What I want).

I understand if I say set

Code: Select all
#local=/localnet/


to:

Code: Select all
test.lan=/test.lan/192.168.0.160


that will resolve test.lan?

how do I (with the setup above) get the dnsmasq to listen to everything that goes through the router to load sites up in windows?

Again thanks :)

*** EDIT ***

I'm now getting a response from dig, it appears Dnsmasq is working better:

However if I setup the windows 7 machine to use 192.168.0.160 as an alternate dns server I get no internet! so a bit debugging to do, next to get MX records also....

Thanks
