 Posted: Tue Feb 14, 2017 3:32 am Post subject: Setup DNSmasq DNS Server ? |
 |
|
Hi All Im back again...
eccerr0r Was a great help with my last problem.. but now I'm hoping someone can help me out with simplifying my local network a little better...
I have a Gentoo/home router made approx 1 year ago from the wiki here.. and I am using DNSmasq to provide my dhcp clients their address ..
quick overview of network
BELL DSL MODEM --> GENTOO ROUTER / APACHE SERVER --> MY NETWORK
My network is made up of Multiple Gentoo Linux machines / iMACs / WINDOWS / etc
I would like to get DNSmasq to provide HOSTS files to all my machines so i don't have to setup hosts files on each of my machines
can someone help me with this as I have tried many times to setup a DNS server (I think this is what i want to do) but have never had any luck getting a DNS server to actually work.
thanks in advance

Take a look at the Wiki article first. Let us know what you don't understand.

DNS has always been my downfall I usually manually point my machines to 8.8.8.8 8.8.4.4
So I should make
Gentoo Router
| Code: |
/etc/resolv.conf
NAMESERVER=8.8.8.8
NAMESERVER=8.8.4.4
|
rest of computers on network
| Code: |
/etc/resolv.conf
#LOCAL NETWORK
NAMESERVER=192.168.0.1
#AWAY FROM HOME (LAPTOP)
NAMESERVER=8.8.8.8
NAMESERVER=8.8.4.4
|
then this should make the computers Look at Gentoo Router first to get DNS information if I am connected to the local network once then if I am not on local network it will try the google dns servers..
So if connected to Local network DNS MASQ should use the /etc/hosts file to connect to local network stuff and then if it can't find the information in the /etc/hosts file it will then use the /etc/resolv.conf and send information thru google name servers... is this correct?
I tend to overthink the problem and make it harder then it is.. But being new to the world of Linux I get confused .. Im pretty sure I have done the top and I either can't get to the outside network or the local stuff still don't work.... I am going to post my host file in the next post... maybe I am doing something wrong in there
and do I delete my host files off of the local machines to make the computers use my gentoo routers host file? |

Here is the Hostfile on my gentoo router (GW1 -- GENTOO ROUTER is HEADLESS all work on this machine is done thru SSH)
| Code: |
/etc/hosts
# /etc/hosts: Local Host Database
#
# This file describes a number of aliases-to-address mappings for the for
# local hosts that share this file.
#
# In the presence of the domain name service or NIS, this file may not be
# consulted at all; see /etc/host.conf for the resolution order.
#
# IPv4 and IPv6 localhost aliases
127.0.0.1 GW1.mike-net GW1 localhost
::1 GW1 localhost6.localdomain6 localhost6
# Local Systems On Network
192.168.0.100 imac.mike-net imac
192.168.0.200 DT0.mike-net dt0
192.168.0.101 GW2.mike-net gw2
192.168.0.110 PI1.mike-net pi1
192.168.0.111 PI2.mike-net pi2
192.168.0.106 acer.mike-net acer
# For Apache virtual hosting:
127.0.0.1 localhost cowboy0629.ddns.net
127.0.0.1 localhost needfulthings.ddns.net
#
# Imaginary network.
#10.0.0.2 myname
#10.0.0.3 myfriend
#
# According to RFC 1918, you can use the following IP networks for private
# nets which will never be connected to the Internet:
#
# 10.0.0.0 - 10.255.255.255
# 172.16.0.0 - 172.31.255.255
# 192.168.0.0 - 192.168.255.255
#
# In case you want to be able to connect directly to the Internet (i.e. not
# behind a NAT, ADSL router, etc...), you need real official assigned
# numbers. Do not try to invent your own network numbers but instead get one
# from your network provider (if any) or from your regional registry (ARIN,
# APNIC, LACNIC, RIPE NCC, or AfriNIC.)
#
|
Now I'm pretty sure I have done this part wrong so if someone could tell me what it should actuaally look like
| Code: |
# IPv4 and IPv6 localhost aliases
127.0.0.1 GW1.mike-net GW1 localhost
::1 GW1 localhost6.localdomain6 localhost6
|
I would like to get IPv6 working as well but one problem at a time... because I don't know anything at all about Ipv6 except the Ipv6 ip address looks more like a mac address
So would I add
| Code: |
/etc/hosts
# For Apache virtual hosting:
127.0.0.1 localhost cowboy0629.ddns.net <--/
127.0.0.1 localhost needfulthings.ddns.net <--\ if I take these two lines out my virtual hosting does not work to the outside world
## ADD LINES BELOW
192.168.0.1 cowboy0629.ddns.net
192.168.0.1 needfulthings.ddns.net
|
If I add the above to the host files of the client machine it works while Im at home but then when I leave the house I have to delete them lines from client machine to view sites over the internet this is why I want my machine to provide a local dns so when I come home with a laptop it will see my websites so I can work on them and test... and then when I leave home I can see them without having to edit the host file all the time on my laptop |

Hey Cowboy0629
First off: Normally the dhcp server tells the clients which DNS servers to use! It is possible that the google servers aren't reachable in a network with local resolvers in place.....
Dnsmasq is first of all a DNS server and if you enable its dhcp features it will promote itself as DNS server to its dhcp clients.
Dnsmasq reads the /etc/hosts on the machine where it is running and distributes these entries! So if you place the ddns name there pointing to localhost, then your clients will not reach your sites with that name - as they are not running on localhost (the client)! You will need to solve that somehow!
I guess it should be enough if you just use the ddns hostnames on the internal ip of the router in your hosts.
If you use the dns settings provided by the dhcp server you also don't have to change your hosts file on the clients if you leave the house..... 
HTH

hypoid is the DNS server to the LAN, and has a fixed IP in network startup. The other machines (except the router and the access point, each of which has a fixed IP) use dhcp, and dnsmasq assigns them the IP addresses listed in my /etc/dnsmasq.d/dnsmasq-local.conf file. |

Ok I don't have the /etc/dnsmasq.d/dnsmasq-local.conf directory so now I know I have done something wrong.... 
I have
/etc/dnsmasq.conf

I just realized that Connection Manager (connman) changes my resolve.conf to
| Code: |
# Generated by Connection Manager
nameserver 127.0.0.1
nameserver ::1
|
does not matter what connection I am on same thing |

Putting the material in /etc/dnsmasq.conf works too. I created the /etc/dnsmasq.d directory, and populated it, so that when dnsmasq is updated by portage, I have fewer changes in /etc/dnsmasq.conf.
| Code: | # Include another lot of configuration options.
#conf-file=/etc/dnsmasq.more.conf
#conf-dir=/etc/dnsmasq.d
# Include all the files in a directory except those ending in .bak
#conf-dir=/etc/dnsmasq.d,.bak
# Include all files in a directory which end in .conf
conf-dir=/etc/dnsmasq.d/,*.conf |
I don't know connman. I recently looked at networkmanager, and it too appeared to take over all or parts of network setup. However, there was a means to cause it to use a dnsmasq.config other than the hardcoded dnmasq.conf command line in networkmanager.
Okay ... edit to add, sussed this from the connman webpage (and I notice the unmasked connman in the portage tree is pretty old)
| Code: | | Thanks to Mylène Josserand, ConnMan 1.31 now properly exposes multiple cellular contexts provided by oFono whenever supported by the cellular subscription. In addition, ConnMan now writes its resolv.conf file to [/var]/run/connmand with the provided tmpfiles.d and init script creating the run-time directory and a symlink from /etc/resolv.conf. If the run time directory does not exist, ConnMan falls back to modifying /etc/resolv.conf as before. |

As for using the same netname inside the LAN as outside, and getting to the same place, that involves both DNS resolution, and routing of packets from outside the LAN.
If I am inside the LAN, cboldt.is-a-geek.net resolves to 192.168.0.1
Again, from /etc/dnsmasq.d/dnsmasq-local.conf (or /etc/dnsmasq.conf)
| Code: | | cname=cboldt.is-a-geek.net,hypoid |
If I am outside the LAN, I am outside my own DNS, so get whatever IP address is served by the DNS I am petitioning for network addresses. At this moment, cboldt.is-a-geek.net is at 72.224.158.246
In addition to IP address resolution, when I am outside the LAN, connections to cboldt.is-a-geek.net first hit the router, and the router decides what to do with those packets. From your question, you have that part working.
Edit to add: curvate.net works the same way. It is 192.168.0.1 to machines inside the LAN, and until my ISP reassigns my IP address, it is 72.224.158.246 to machines that are outside of the LAN. The specific names like "printhost" and "jabber," those are NOT visible outside the LAN. |

How do I go about setting this dnsmasq.d directory up.. I like when config files are in a dir like that because then I don't have to worry about the system updating them and I remember reading about that but figured i couldn't do that with gentoo because the DIR was not there... But once this directory is set up.. instead of putting my address in the dnsmasq.conf file I just put them in a file inside this directory correct? and then I don't have to restart the service every time I make a change..
thanks for all your help so far.. Im still lost in the above answer but I thinking if I get things cleaned up on my server it will be easier to folow your examples Do I just create directory? and then what do I call the host file in there |

Use the command line. If you are not logged in as root, preface the two command below with "sudo"
| Code: | cd /etc
mkdir dnsmasq.d |
Or, since we know /etc exists, just `mkdir /etc/dnsmasq.d` will work.
Then you have to configure dnsmasq to look there. The supplied /etc/dnsmasq.conf has example lines for this. I used the example that loads everything named /etc/dnsmaq.d/*.conf
I try to use "local.cfg" files whenever possible, for exactly the reason you mentioned.
As for having to restart or not, read the man page for dnsmasq. Some information will update automatically (/etc/hosts and similar, if I recall), some other information will be re-read if the running dnsmasq is send a SIGHUP (some DHCP material), and other information requires stopping and restarting.
Edit to add: call the host file whatever you want. I have three files in /etc/dnsmasq.d. "banner-ads.conf", "local-block.conf", and "dnsmasq-local.conf" My "dnsmasq-local" has the dhcp-by-MACID assignments as well as the aliases and other settings. You can break your local config up into separate files, combine them all in one file, whatever floats your boat.
The "banner-ads" file is taken from https://pgl.yoyo.org/adservers/serverlist.php, using the "address=/101com.com/127.0.0.1" form. |

I think I got it now.. But not 100% yet I will let you kknow when I get home testing everything remotely with work I it seems to be finding the websites now from a computer on the local network but hard to tell...
next i was wondering if there was a way to get dnsmasq to assign a static ip to a computer using the host name of the machine because my laptop has 2 mac address wireless and wired... (I use connman becuase i use the e21 desktop environment) but I miss network manager because I would just clone the wireless mac with the wired... so I am unabe to get them to work the same address... I like being able to access any of my computers from anywhere in the house from any machine.. ..
I tried putting both mac address into dnsmasq with the same address and it will not let me do this so
I need dns masq to say <hostname> = IP address
thanks for all help

The dhcp-host= lines are powerful! Below lifted straight from the dnsmasq.conf file shipped with the package.
| Code: | # Supply parameters for specified hosts using DHCP. There are lots
# of valid alternatives, so we will give examples of each. ... The order of the
# parameters in these do not matter, it's permissible to give name, address
# and MAC in any order.
# Give a host with Ethernet address 11:22:33:44:55:66 or
# 12:34:56:78:90:12 the IP address 192.168.0.60. Dnsmasq will assume
# that these two Ethernet interfaces will never be in use at the same
# time, and give the IP address to the second, even if it is already
# in use by the first. Useful for laptops with wired and wireless
# addresses.
#dhcp-host=11:22:33:44:55:66,12:34:56:78:90:12,192.168.0.60
# Give the machine which says its name is "bert" IP address
# 192.168.0.70 and an infinite lease
#dhcp-host=bert,192.168.0.70,infinite |
For that second example, I assume that "bert" has to communicate his HOSTNAME when requesting an IP address. For the first example, I assume that in addition to assigning the IP addy, dnsmaq would be happy to assign the "hostname" too. |

As for accessing any machine, consistently, the need for a known IP depends on your habits and preferences. I like to know the IP addy in case dnsmasq fails (or I fail to set it up right), but in practice, I think I "always" call the machines by name, so don't care what their local IP is.
I also use a little trick in /etc/ssh/ssh_config, which associates an alias (home) to a netname, but only for ssh related action (which applies to ssh, of course, but also to scp and rsync)
| Code: | Host home
Hostname cboldt.is-a-geek.net |

thanks.. that paragraph for some reason is not in my .conf file... I thought I seen it at some point.. but I thought it was on a website.. and you know how it goes you see a website with great information and can't find it again when you actually want it... |

i read your stuff.. and everything has your domain name attached to it.. am I able to do this with my domain once I get it on wednesday.. I have finally decided not to use the ddns.net address and get myself an actual domain.. Thank-you for all your help so far I will know tonight if my original question has been solved.. No I am wondering if I should continue on with the hostname.domain.com stuff or ask a new question |

cboldt.is-a-geek.net is a DDNS name. The IP changes at the whim of my ISP, and it falls to me to keep the name/IP association up to date.
There are a bunch of places that will hand you a DDNS name for the asking. is-a-geek.net is hosted by dyndns (dyn.com), and they offer quite a few options, including is-a-llama.com and broke-it.net.
curvate.net also resolves to here. That name I had to pay for separately.
I use a cronjob script to daily check what IP my ISP has given me. It changes maybe a few times a year. When it does, the script calls ez-ipupdate to inform dyndns of the change. |

Is GW2 getting its DNS from your dnsmask setup? It can either be told to get its DNS service via the IPs named during dhcp network setup, or it might be configured to get its nameservice elsewhere. I use `dig` to figure out what the machine is using for dnsserver. `dig gw1`
I also think you have the "cname" parameters reversed. The alias is first, the real HOSTNAME is second.
Separately, your machine "acer" can be defined as ...
| Code: | | dhcp-host=30:52:cb:46:8b:ad,30:65:ec:91:83:f0,acer,192.168.0.106 |
Then "acer" can just get it's net config via dhcp, with dnsmasq giving the name and IP regardless of which MACID comes over the transom.
My pleasure being of help.
Edit to correct: I think you have the right order in cnames. Assuming gw2 is getting nameservice from your dnsmasq machine, the question is whether or not "gw1" ever gets an IP address. My "home" machine has a HOSTNAME=hypoid, and that relationship is defined in /etc/hosts on "hypoid" That /etc/hosts file includes the LAN address for hypoid (192.168.0.1), which matches the network setup in /etc/conf.d/net on "hypoid", which asserts that fixed IP for itself. |

just realized I sent you the resolv.conf out of gw2 in the above post.. the actual resolv.conf for GW1 (router) is
| Code: |
/etc/resolv.dnsmasq.conf
nameserver 127.0.0.1
## External nameservers
# Google #
nameserver 8.8.8.8
nameserver 8.8.4.4
