Now I'm thinking when I remove dnsmasq I also need to remove odhcpd-ipv6only before installing dnsmasq-full.

The dnsmasq DHCPv6 server provides the same set of features as the DHCPv4 server, and in addition, it includes router advertisements and a neat feature which allows nameing for clients which use DHCPv4 and stateless autoconfiguration only for IPv6 configuration. 1537853508 18:b4:30:be:9a:b0 192.168.3.120 01:18:b4:30:be:9a:b0, Mon Sep 24 09:06:59 2018 daemon.notice odhcpd[1529]: Got DHCPv6 request This script does the work of locating and changing the firewall rule.

Hopefully that will give some insights. DNS and DHCP configuration for OpenWRT https://wiki.openwrt.org/doc/uci/dhcp The dnsmasq and dhcpd configuration is located in /etc/config/dhcp and controls both DNS and DHCP server options. Both versions worked in both of my routers. The versions are built during the same build run, so they should be as identical as possible. I have managed to set up DNS on my router without the need for static IP addresses using dnsmasq as the main DHCP client. Firewall settings It's important to note that the addresses your clients will be reachable publically, much unlike the standard IPv4+NAT setup commonly used. 1537869657 78:d2:94:4f:ec:21 192.168.1.126 * * Changeset r34106 (isolating stamp files for build variants) has apparently broken dnsmasq package's dhcpv6 variant. lzma_fs returned unexpected result 0x1 You should review the, r34106 (stamp files for build variants) broke dnsmasq package's dhcpv6 variant. When you have a router running OpenWRT this can be done at the firewall level. This ticket should maybe closed as invalid and a new one opened, as the problem description is wrong. Next status will be 'reopened'. http://linux.die.net/man/1/lzma returned, and that is 1. The steps to get this working are as follows: The first step is to install the required packages. to your account. Restart your dnsmasq server to activate the new settings and verify that your clients successfully receieve IPv6 addresses. 1537871020 a0:6a:44:52:89:03 192.168.1.118 * 01:a0:6a:44:52:89:03 (see below from lzma help file.). When the router "did not boot", it started the boot process but then got stuck in the middle, just the power led slowly blinking. Already on GitHub? I have solved this by deleting the lease files (/var/lib/NetworkManager/.lease on Ubuntu and /var/lib/dhcpcd5/.lease on Raspbian) and then reconnecting the network. option dhcpv6 'server' 1537866076 8c:3b:ad:e3:3c:f8 192.168.1.107 01:8c:3b:ad:e3:3c:f8 Every received DNS query not currently in cache is forwarded to the upstream DNS servers. THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. I checked some of the the "bad builds" with a hex editor, but there are a few dozens of 00 bytes at the end of the kernel area, so kernel size overflow is not the reason.

So no clue from the error number. Sign in In particular, on my router both DNS and DHCP are handled by unbound. I ordered a serial-USB converter, so in a few days I may have more info. First we'll add a firewall rule to be dynamically updated: Upon a new or renewed lease, Dnsmasq calls the script /usr/lib/dnsmasq/dhcp-script.sh, which, in turn calls /sbin/hotplug-call dhcp (after setting up an environment). I have flashed both routers over 100 times, but that should not be too much for the flash chip, should it? option ra 'server' SQUASHFS error: squashfs_readdir: read_block I threw that away so I can't verify my assumption. One supporting factor for this line of reasoning is that there was one firmware version, the first with which I noticed this problem, where I had succesfully flashed my 3700v1, but that then failed in a 3700v2, although it had been built on the same compilation run. Alternatively, the new Virtualbox version 4.2.4 screws things up. Since the Linux machines keep ahold of their lease when disconnected, something about the lease renewal process (as opposed to the full lease negotiation process) doesn't trigger Dnsmasq to add the client to the DNS. Both static and dynamic DHCP leases are supported, along with stateless mode in DHCPv6. Dnsmasq, however does provide such callbacks making automatic updating of firewall rules a relative breeze. errors are returned, but in most cases just LZMA_RESULT_DATA_ERROR is Thank you for leading me to discover the solution! It looks like including dnsmasq-dhcpv6 variant after r34106 causes the router not to boot up. I just didn't have to do this with LEDE V17. I have now a serial to USB converter and the bootlog from serial console is as below. So, we need to add some sections to the /etc/dnsmasq.conf file that contains the remainder of the configuration. Sections The firmware gets built normally and there is no apparent fault in the build process. If nobody else starts complaining about similar issues, this might be something specific to my buildhost :-( My build host is Ubuntu 12.04 x64 in Virtualbox, but I have used the same machine to build Openwrt since April 4-5 times per week, so it sounds strange that it would have broken down now. By Edgewall Software. Please provide a complete bootlog. The key part is probably: I earlier thought that it might be faulty flash memory, but at the first glance that does not sound like that, as checksum is right, but lzma_fs returns error regarding squashfs. option expandhosts '1' option local '/lan/' But if youre not much into advanced configuration and just want to completely block out some network hosts from reaching the internet (and hence phoning home) then its a lot simpler to do this directly from the DHCP and simply leave them without a DNS and gateway configuration.

Start with editing /etc/config/dhcp to add the following tag definitions in the file (tag identifier can be any string, I chose these for clarity purposes): These definitions stop the DHCP server from providing gateway and/or DNS information to the hosts they are applied to. This wasn't an issue on any of the LEDE 17 versions but has been an issue on the OpenWrt 18 versions. 4 # This is free software, licensed under the GNU General Public License v2.

Apparently the previous build's leftovers are enough to get included in the final firmware. Powered by Discourse, best viewed with JavaScript enabled, Configuring DNS using dnsmasq DHCP and dynamic IPv6 firewall rules, Configure dnsmasq to provide DHCP and DNS. Let's add one: This script simply does a sanity check to ensure we're updating the firewall rule to the correct host by matching the hostname and the DUID. During the past few months I have had in my config the normal dnsmasq disabled and dnsmasq-dhcpv6 enabled. dnsmasq provides a DNS server, a DHCP server with support for DHCPv6 and PXE, and a TFTP server.

At the first glance it looks like the lib_bootstarp/lzmadecode.c basicly Otherwise the system is working fine, I can see in DHCPv6 leases being issued. It works but it's not the most graceful solution. Request an /56-prefix using dhcpv6-pd and configure a prefix delegation; Set up dnsmasq to handle router advertisement and dhcpv6 along side the regular dhcp for IPv4; And then covering some basics. There are multiple ways to delegate and obtain IPv6-prefixes, the most common way is that your ISP delegate a prefix to you using slaac or dhcpv6. To serve custom information instead include the IP addresses in the options definition, for example: Then create mac-specific host configurations and add the tag attributes to the hosts that should receive the custom configuration: Save changes to the file (via SSH/SCP) and then reload and use Save & Apply on OpenWRTs DHCP and DNS page to make the configuration changes apply. several conflicting dnsmasq variants. (diffconfig added to the ticket). It would be helpful if you could attach serial and capture the bootlog of the device failing to boot. Those differ from the defaults mentioned in the lzma's built-in help texts, and do differ from Netgear's build process (which uses the defaults in lzma and version 4.32, not 4.65). package: dnsmasq-full Name: dnsmasq-full Version: 2.85-8 Description: It is intended to provide coupled DNS and DHCP service to a LAN.\\ \\ This is a fully configurable variant with DHCPv4, DHCPv6, DNSSEC, Authoritative DNS\\ and IPset, Conntrack support & NO_ID enabled by default.\\ Installed size: 178kB Dependencies: Instead, we'll want to install dnsmasq-full opkg update && opkg install dnsmasq-full This issue is probably due to my router handling DNS/DHCP different than the standard openWrt setup.

I really fail to see how a broken dnsmasq-dhcpv6 would prevent the router from booting. I have already built newest trunk 34245 and it works both in my v1 and v2 routers. The problem is there for several WNDR3700/3800 users, but it is probably something related to invalid lzma compressed images instead of package stamps. Of course, if you change all instances of home.example.com to a real domain and set up some glue records you can get to all the devices from the outside (provided you have port forwards set, of course). The problem with odhcpd is that it doesn't provide script callbacks that will notify of new or renewed DHCP leases.

It is designed to be lightweight and have a small footprint, suitable for resource constrained routers and firewalls. (Alternative reason might be something wrong in image generation.). And a new 34085 then booted ok in both routers. The boot process after that looks quite similar to the failing ones until the point where squashfs image is successfully decompressed to 0x80800000 and then control gets transferred to Linux kernel: Somehow I find it hard to believe that is a flash failure.

And that has worked ok. After r34106 that combination stops the router from booting. Somehow it sounds like there is an illegal structure in the squashfs compressed image that breaks the decompression, or something like that. 1537868184 00:e0:4c:36:e9:17 192.168.1.112 * Have a question about this project? At least my ar71xx/wndr3700 does not. /sbin/hotplug-call dhcp executes scripts in the /etc/hotplug.d/dhcp folder. I am thinking about alternative explanations, and the first that comes into mind is the current ar71xx/wndr3700 kernel size optimization in the build process. But I'm sure I see DHCPv6 leases being issued in the log. Looks like the reason was indeed the lzma compression parameters. The firmware gets built normally and there is no apparent fault in the build process. One idea is the lzma parameters " -lc1 -lp2 -pb2 ", which have been introduced without any explanation four years ago with r12628. This website uses cookies. When the boot fails, the router answers to ping at 192.168.1.1, but does not answer to any connection attempt with telnet or ssh. It sets the size based on the estimation size, it first calculates the used 64k blocks and rounds upward to the next 64 kB size. You really need to know why you want to prefer dnsmasq over odhcpd for IPv6, there's a reason why odhcpd is developed - dnsmasq is lacking in regards to dynamic prefixes (thanks dear ISPs) and other domains. But if you "make clean" and build then a post-r34106 version, the build succeeds but is not bootable. https://dev.openwrt.org/browser/trunk/target/linux/ar71xx/image/Makefile#L571. option dnssec '1' (I made the last build without clean, as it was supposed change just the image creation), Read about the lzma/xz memory consumption here: Anything better? By default, there are no scripts here. This allows better performance and management of DNS functionality on your local network. I guess that router somehow does not boot properly from u-boot to kernel, or something like that. ### SQUASHFS loading 'image/uImage' to 0x80800000 I built 34036 and 34066 fully from scratch and they both worked both in v1 and v2.
