"Active DHCPv6 Leases" on status page is empty if system is running dnsmasq-full. Otherwise the system is working fine, I can see in DHCPv6 leases being issued. I have been unable to determine a clear reason to create failing/booting images, and I have used the vanilla dnsmasq today (with no dhcpv6 support). Instead, we'll want to install dnsmasq-full, For testing purposes, we may also want to install the dig command. dnsmasq provides a DNS server, a DHCP server with support for DHCPv6 and PXE, and a TFTP server. And that booting difference sounds strange. During the past few months I have had in my config the normal dnsmasq disabled and dnsmasq-dhcpv6 enabled. It seems I'm lying, I don't see any DHCPv6 leases. The problem is there for several WNDR3700/3800 users, but it is probably something related to invalid lzma compressed images instead of package stamps. (Alternative reason might be something wrong in image generation.). 1537868184 00:e0:4c:36:e9:17 192.168.1.112 * I threw that away so I can't verify my assumption. option resolvfile '/tmp/resolv.conf.auto' When you have a router running OpenWRT this can be done at the firewall level. 4 # This is free software, licensed under the GNU General Public License v2.

Alternatively, the new Virtualbox version 4.2.4 screws things up. I had to de-brick it with a TFTP flash to get it back to running order. option rebind_protection '1' The problem with odhcpd is that it doesn't provide script callbacks that will notify of new or renewed DHCP leases. 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. 1537861626 0c:b2:b7:45:6c:b4 192.168.3.172 -0B3E 01:0c:b2:b7:45:6c:b4 If you want to contribute to the OpenWrt wiki, please post HERE in the forum or ask on IRC for access. So, we need to add some sections to the /etc/dnsmasq.conf file that contains the remainder of the configuration. I will attempt to increase the buffer set in Makefile and try rebuilding tonight. (diffconfig added to the ticket). 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. 1537854905 4c:605d:8e:e3 192.168.1.116 * * It was a bit of a process and quite a steep learning curve, so I figured I'd document what I did here on the forums in case anybody else finds themselves wanting this feature. This wasn't an issue on any of the LEDE 17 versions but has been an issue on the OpenWrt 18 versions. Jow is probably right that it is not about that package. 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. I then modified the ar71xx image makefile and removed those non-standard compression parameters from the lzma command line. And that has worked ok. After r34106 that combination stops the router from booting. option localise_queries '1' Next status will be 'reopened'. If the prefix were to change, your existing firewall port forwards for IPv6 will be crippled until you manually re-set them at some point. ), overall it's not a terribly painful process. At least my ar71xx/wndr3700 does not. You should review the, r34106 (stamp files for build variants) broke dnsmasq package's dhcpv6 variant. 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. package: dnsmasq-dhcpv6 Name: dnsmasq-dhcpv6 Version: 2.85-8 Description: It is intended to provide coupled DNS and DHCP service to a LAN.\\ \\ This is a variant with DHCPv6 support\\ \\ Installed size: 157kB Dependencies: libc, libubus20210630 Categories: base-system Repositories: base Architectures: It looks like including dnsmasq-dhcpv6 variant after r34106 causes the router not to boot up.

Looks like badly confused build config in .config, as you are trying to install e.g. returns 0 for success and 1 for most errors. Then I built 34085 and it failed in both routers. This script does the work of locating and changing the firewall rule. Sections SQUASHFS error: squashfs_readdir: read_block option dnsseccheckunsigned '1', config dhcp 'lan' While there is a little bit of configuration involved and a couple of custom scripts to fill in the functionality gaps (be sure to include the files in your backups! I have flashed both routers over 100 times, but that should not be too much for the flash chip, should it? Hang on, odhcpd? 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. The resolution will be deleted. Self-registration in the wiki has been disabled. (according to juhosg, this will probably be later fixed in AA, after the rc1 images have been built.). ERROR: LzmaDecode.c, 547 As you're probably aware, IPv6 prefixes can change pretty frequently depending on your ISP. Somehow it sounds like there is an illegal structure in the squashfs compressed image that breaks the decompression, or something like that. I fetched wndr3800 sources from Netgear and extracted the u-boot part here: If nobody suggests anything better, I will continue to live with this change: Fixed in trunk with r34248 which applies the 20-bit dictionary size option "-d20" to just wndr3700/3800 instead of all ar71xx images. let 'kk = (((s + c) / (64 * 1024) + 1) * 64)'; which sets the allocated kernel size. 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. ### SQUASHFS loading 'image/uImage' to 0x80800000 Please provide a complete bootlog.

Looks like the reason was indeed the lzma compression parameters. 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. 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 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. option ra 'server' But if you "make clean" and build then a post-r34106 version, the build succeeds but is not bootable. Some of the builds have worked, some have not, even regarding version 34105. option dhcpv6 'server' option leasefile '/tmp/dhcp.leases' I will rebuild 34085 once again from scratch and retry. I actually created the images with two different parameter lines in target/linux/ar71xx/image/Makefile: First that already discussed removal of the current parameters: But then also with original parameters, but added the directory size limitation from the default 8MB to 1 MB = 20 bits. By Edgewall Software. 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. to your account. dnsmasq's dhcpv6 variant got introduced by r32764. Configure dnsmasq to provide DHCP and DNS Bonus: Dynamic IPv6 firewall rules Install Packages The first step is to install the required packages. lucenera January 14, 2019, 8:18pm #5 I followed the Github page of the Stubby package to configure DNS on TLS. Now I'm thinking when I remove dnsmasq I also need to remove odhcpd-ipv6only before installing dnsmasq-full. option interface 'lan' Both versions worked in both of my routers.

Apparently the previous build's leftovers are enough to get included in the final firmware. When the router "did not boot", it started the boot process but then got stuck in the middle, just the power led slowly blinking. 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. Changeset r34106 (isolating stamp files for build variants) has apparently broken dnsmasq package's dhcpv6 variant. Details are below. 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). option authoritative '1' It includes proxy-mode, where the PXE system co-operates with another DHCP server. This ticket should maybe closed as invalid and a new one opened, as the problem description is wrong. Reading whole flash contents from /dev/mtd and comparing to the original image? If you do not agree leave the website. https://dev.openwrt.org/browser/trunk/target/linux/ar71xx/image/Makefile#L571. Regards, Jim Once this is all set up, you should be able to dig @[router_ip] AAAA [hostname].home.example.com. I was unable to connect to the router with telnet or SSH, so there is no bootlog available. dnsmasq. 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. At the first glance it looks like the lib_bootstarp/lzmadecode.c basicly I have already built newest trunk 34245 and it works both in my v1 and v2 routers. E-mail address and user name can be saved in the Preferences. It is designed to be lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It would be helpful if you could attach serial and capture the bootlog of the device failing to boot. Dnsmasq, however does provide such callbacks making automatic updating of firewall rules a relative breeze. http://koti.welho.com/hnyman1/Openwrt/trunk_error_does_not_boot/Netgear3800_uboot.zip. The strange thing is that I can flash again those firmware images that I know from earlier experience to be working. The firmware gets built normally and there is no apparent fault in the build process. option limit '150' 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. Well occasionally send you account related emails. http://sourceforge.net/projects/lzmautils/forums/forum/708858/topic/3965542, Based on those articles, it might be sensible to either revert to default parameters, or based on seeing the parameters at staging_dir/host/bin/lzma to change the default directory size from 23 bits (8 MB) to something smaller, as the firmware is usually much smaller. Then, it calls a script that I've stored in /usr/sbin/update-uci-firewall-rule. 1537871020 a0:6a:44:52:89:03 192.168.1.118 * 01:a0:6a:44:52:89:03 But the router does not start after the flash. of the source file, possibly from this function: That would suggest that the error is related to the structure of the http://linux.die.net/man/1/lzma Dnsmasq serves as a downstream caching DNS server advertising itself to DHCP clients. My kernel size is currently quite at a 64 kB border (917117, 916862 B = 13,994 x 64kB), and I am thinking if it is possible that the estimation is a few bytes short and the final kernel image just crosses the border by a few bytes and thus the kernel bootline gets set wrong. 1537832014 b4:f7:a1:be:e3:00 192.168.3.115 * 01:b4:f7:a1:be:e3:00 The PXE system is a full PXE server, supporting netboot menus and multiple architecture support.

One idea is the lzma parameters " -lc1 -lp2 -pb2 ", which have been introduced without any explanation four years ago with r12628. config dnsmasq The versions are built during the same build run, so they should be as identical as possible. Note: DHCP is handled by unbound with the help of odhcpd.dnsmasq is not used (or even installed for that matter). Have a question about this project?

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. Changeset r34106 (isolating stamp files for build variants) has apparently broken dnsmasq package's dhcpv6 variant. Is there any good way to check the flash quality? And a new 34085 then booted ok in both routers. I see DHCPv6 leases displayed until I remove "dnsmasq" and install "dnsmasq-full". This wasn't an issue on any of the LEDE 17 versions but has been an issue on the OpenWrt 18 versions. I have now a serial to USB converter and the bootlog from serial console is as below. There are several places where 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. Sign in I have uploaded the build r34174-2012-11-12-2328 to http://koti.welho.com/hnyman1/Openwrt/trunk_error_does_not_boot/ , so if somebody wants to test the build with a v1, please do so. 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. option domain 'lan' generated lzma encoded file. A new Flyspray task has been opened. When I receive the serial port converter, I will test my 3700v1 and see the boot log what it says.

It looks like including dnsmasq-dhcpv6 variant after r34106 causes the router not to boot up. dhcp: opkg_install_cmd: Cannot install package dnsmasq-dhcpv6. option dnssec '1' I see DHCPv6 leases displayed until I remove dnsmasq and install dnsmasq-full. It works but it's not the most graceful solution. https://forum.openwrt.org/viewtopic.php?id=40565. So that some bit does not get toggled by flashing any more, and it randomly depends on the firmware image, if the bit is right. dnsmasq-dhcpv6 looks a bit strange compared to most packages, as it tries to be a variant instead of being an add-on toggle to decide on inclusion of dhcpv6 functionality in the main package. This allows better performance and management of DNS functionality on your local network. There are times when you need to filter out what some hosts in the network can or cannot do. 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. dnsmasq-dhcpv6 is visible in menuconfig next to normal plain dnsmasq. option ra_management '1', dhcp.leases: 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.
