Hi Simon, thanks for your time! :) FYI: When I use dibbler-server, my cisco wlan-ap gets an ipv6-address leased with default config.

It it possible to alter that config? If so can you try without "send
rapid-commit", to see if that improves things?

[Dnsmasq-discuss] DNSMasq DHCPv6 seems to fail with dhcp6c
Hello!
I've here an WLAN-AP from Cisco. It's the WAP4410N.
It supports nativly IPv6 and DHCPv6.
My Problem is, it seems not got get an IP from DNSMasq for IPv6. As I
have SSH on this AP, i debugged a little bit.
There is the client "dhcp6c" installed.
The config there is:
interface br0 {
send rapid-commit;
request dns-servers;
request domain;
};
I am attaching verbose log files of dnsmasq-dhcp and dhcp6c. Can someone
look into it? Is this a problem with dnsmasq, or is this the fault of
Cisco and dhcp6c? As I see in the log, there seems to be given an IP to
my AP, but my AP does not use it?
Thanks!
Conrad

Re: [Dnsmasq-discuss] Detect conflicting DHCP servers
Contacting DHCP servers is a task for a DHCP client, not a DHCP server. There are a number of scripts available which will send a request and listen to all responses (not just the first), generating an alert if any unexpected nodes responded. Google "rogue DHCP detect".

[Dnsmasq-discuss] Feature Request(s)
Hi Simon - I'm a big fan of DNSMasq, it's great software, thanks all for your hard work. I had three requests/questions I just wanted to throw out there that would come in handy for simplifying configuration in what I think would be an intuitive way. For the most part, this is related to consolidating DNSMasq implementations into a single config file and extending cmd line syntax to reduce reliance on external files. I really like the self contained simple nature of DNSMasq and I won't be happy until it's as powerful and cryptic as Perl ;) 1) address=/domain/ip works great as described, but *.domain and *.*.domain (etc...) also resolv based on this syntax. Syntax like address=/.domain/ip that would prevent *.domain from resolving, or address=/..domain/ip would prevent *.*.domain but allow *.domain, something in that vain, would come in handy. That way, single A records could be overridden with address=/.host/ip so I could keep everything in a single dnsmasq.conf file without maintaining a separate addn-hosts file. Seems like this could extend functionality in a very intuitive, backwards-compatible way without adding much messiness to config or documentation. 2) Any reason why an /etc/hosts syntax line can't be put in a dnsmasq.conf file? As far as I can tell it wouldn't break the dnsmasq syntax, and it would allow for consolidating files in a very intuitive, minimalist way. 3) If #1 & #2 aren't feasible, how about something like a=host,ip that would allow for an A/PTR pair in more traditional dnsmasq.conf style syntax, to reduce the need for an addn-hosts file. 4) How come cname= only works for local hosts? Would that be difficult to implement so you could create CNAMEs for A records hosted on upstream servers? regards, Rob ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
[Dnsmasq-discuss] Detect conflicting DHCP servers
Dear list, our DHCP requests are handled by dnsmasq on the main server. Every now and then a technically illiterate person connects a device to the network that by default acts as DHCP-server, may it be a print server or a switch. Is there a way to tell dnsmasq to periodically scan for other DHCP-servers and give a warning if necessary? Thanks ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
