Needless to say, the death of the machine left my small network in shambles, because I couldn't connect to anything to fix things without first configuring temporary static addresses; sans DHCP, stuff fails... :) I'm anything but a DHCP specialist, but I want to bounce this idea off you anyway, even if you mind. ;-) The trick, as I understand it, in setting up more than a single dnsmasq instance in a network, is to ensure that it uses --dhcp-script to STORE the leases and --leasefile-ro to force the script to produce a list of current leases ("init") from which a launching dnsmasq obtains its data before going on its usual business. If we were able to ensure the "data store" (i.e. lease database) were available on two machines A and B (and up to date on both of course) the solution would be eas</pre> Jan-Piet Mens 2012-05-25T11:17:57 http://comments.gmane.org/gmane.network.dns.dnsmasq.general/5851 <pre>Hi List, I'm currently looking for a solution to provide ssh-keys via DNS. Seems like sshfp records will solve this issue ... so far so good. Since we are using dnsmasq as dns/dhcp/pxe-server I wanted to ask how to put the generated sshfp records into dnsmasq ??? After searching for a while I got only guides for "how to create sshfp records" or things like "put your sshfp records into dns"....not that helpful. Can somebody enlighten me if it is possible to offer ssh keys via dnsmasq, and how to configure it ? I tried it similar to the TXT-Records, therefore I created a config-file sshfp.conf and inserted: "" myhost SSHFP 1 1 cbe4...c6dc myhost SSHFP 2 1 20ea...b241 "" But if I want to start dnsmasq I got the error: "" Starting DNS forwarder and DHCP server: dnsmasq dnsmasq: bad option at line 1 of /etc/dnsmasq.d/sshfp.conf failed!

I think this is at least partially caused by a bug in dnsmasq.c: the main loop only calls icmp6_packet if daemon-&gt;dhcp6 is non-NULL, but dnsmasq should respond to icmp6 packets if it's providing just RA services (no dhcpv6) too. That is: I think dnsmasq.c needs something like this: diff --git a/src/dnsmasq.c b/src/dnsmasq.c index 1b951f0..11c2d73 100644 --- a/src/dnsmasq.c +++ b/s</pre> Marien Zwart 2012-05-21T13:14:44 http://comments.gmane.org/gmane.network.dns.dnsmasq.general/5832 <pre>Is it possible to send a message to the client device when an IP address is allocated via DHCP? This would only be a static info message for my purposes, and it wouldn't matter much if some clients didn't support showing it and so ignored it. Apparently Apple Wi-Fi routers do this, but I'm not sure if this is a vendor-specific addition or something that other DHCP servers are capable of too.

DNS is working fine for A, AAAA, CNAME and PTR records. DHCP for IPv4 is also working. I have recently began to dabble with IPv6 on my LAN and since I do not yet have a provider for IPv6, I have decided to use RFC 4193 Unique Local (fdxx:) addresses for my LAN. Since I only have a few machines, I chose a subnet prefix of /123 and using static IPv6 configuration I was able to ping6 other machines on the same subnet (even by their names), as well as from one subnet to another, even using a sit tunnel. When I set my dhcp-range option in dnsmasq.conf with a prefix-length of 123, I get an "inconsistent DHCPv6 range" error. setting this value to 125 or greater seems to work, also setting it to 120 or less seems to be acceptable to dnsmasq. Checking out my range with an ip calculator didn't reveal any errors (my dynamic ip range is within the same 5-bit subnet).

I installed dnsmasq on some of our boxes and configured the boxes to use 127.0.0.1 in /etc/resolv.conf (so they use dnsmasq). That works really well and I can resolve DNS queries on those boxes. All the queries get send from dnsmasq to our internal DNS server (which has internal zones configured). For testing I checked the incoming DNS requests on the central DNS server with the usage of "dnscap". I encountered a strange thing: When I do a "dig session-storage.fd.corp" (fd.corp is an internal domain) the first time on one box where dnsmasq is installed I can see that one requests comes in on the central DNS server. The second time I execute it, nothing comes in on the central DNS. So it gets cached in dnsmasq which is fine. The problem appears when I do a "dig session-storage.fd.corp" and a "dig AAAA session-storage.fd.corp" alternately. I can see an incoming request for every dig request on the central DNS server which means that there is no ca</pre> Nick 2012-05-18T08:14:28 http://comments.gmane.org/gmane.network.dns.dnsmasq.general/5804 <pre>Hello i am the author of the vim syntax file for dnsmasq: https://vim.googlecode.com/hg/runtime/syntax/dnsmasq.vim Currently i am in the process of updating it for 2.61 and have a question regarding whether it is allowed for comments starting in the middle of the line.

The default value according to the manpage was 1.5 seconds and not changeable. This option lets you set the timeout to a number of milliseconds. I noticed that I had to multiply the given timeout by 2 in order for it to wait the correct amount of time. This is reflected in the PING_WAIT constant as well, which was set to 3 in order to wait 1.5 seconds. While I believe my patch is performing correct behavior, I'd appreciate some explanation as to why this is necessary. I've placed a maxmimum limit of 15 seconds on the timeout. This is because it appears that PING_CACHE_TIME must be greater than the timeout. See the patch made in dhcp.c for the area where this issue is of concern. I have attached the output of `git diff` to this email as a patch. If this is not the correct format, please let me know.

No Router Advertisement and corresponding syslog sendto error when replying on Router Solicitation from Windows XP and possible other OSes It's caused by absence of source IPv6 address in RS packet, what is allowed by RFC if host's interface doesn't acquired valid link-local yet In this case RA should be sent to all nodes multicast address (sources has ALL_HOSTS define, which has a bit different meaning) 2. For non-slaac modes periodic RA doesn't work because next RA event could be reset by empty next slaac event Actually it could work only for the first time, if additional random delay is 0.

I'm running dnsmasq for DHCP services (as part of CloudStack). IP addresses are statically assigned via mac, defined in /etc/dhcphosts.txt. This all works perfectly fine for a single IP block. Until I try to assign IPs for another IP block, and then get May 10 01:28:49 dnsmasq-dhcp[1057]: no address range available for DHCP request via eth0 Problem is, when I order IP blocks from my provider, they're routed to me via my VLAN. I have multiple /28s on this single Ethernet segment. I need dnsmasq to be able to answer DHCP requests to Ethernet addresses with IP addresses that are outside the network range of the listening interface. My understanding is this is a limitation in dnsmasq? On the DHCP side, I can't think of a technical limitation that causes this - DHCP is a layer 3 protocol, it doesn't care about IP ranges on interfaces.

Is there anything in dnsmasq which implements listening on a multicast address? The IANA address allocation does say that 224.0.0.12 is a standard DHCP server address, on which I assume DHCP servers can listen. First: is this even a responsibility of this application layer of the stack, or is it supposed to be implemented in kernel or network configuration? Second: the end goal is to have multiple dnsmasq-based DHCP servers listening on not-well-known IP addresses on the network. Also, the servers should only receive requests from a proprietary relay agent, which won't know the IP address of the DHCP servers. I think multicast is the way to solve this, but I'm not positive. Any ideas? </pre> David Dombrowsky 2012-05-09T20:00:15 http://comments.gmane.org/gmane.network.dns.dnsmasq.general/5771 <pre> Dear DNSMASQ'ers I am developing code for an embedded micro controller with a network interface. I am presently working on the DCHP client code where dnsmasq is both name server and dhcp server. The dnsmasq OS environment is OpenBSD, although I doubt the OS is a factor here. While I am by no means new to network programming, I have never actually written code to make DHCP happen before so I am learning new details as I go. I am considering how to handle the case where the client (my controller) asks for a specific hostname in its DISCOVER and REQUEST messages and I know that specific name is not available because it is committed to an unexpired leaseholder. In no case is dnsmasq responding to my client's option 12 in its OFFER or ACK messages. By that I mean, in cases of a clear name being requested or in cases where the requested name is in conflict with an already committed name, I see nothing from dnsmasq on option 12.
