[Dnsmasq-discuss] Logfile rotation
Hi, I just started using dnsmasq on my home network. It is running on my QNAP TS-509 NAS and it works great! I have a question about log rotation. I know I have to send a SIGUSR2 to perform a log rotation but what exactly happens? How does it work? I enabled logging and there are messages being logged. I issued a kill -12 pid of dnsmasq but nothing happened. IS the log supposed to be renamed and a new one created using the same name specified in the conf file? I've read the man page but I still can' figure out how it works and what is supposed to happen. Thanks Don

logrotate does not exist on the NAS. I can write a script to perform it on dnsmasq if someone would tell me what happens when dnsmasq receives SIGUSR2. -Original Message- From: santiago.j.zar...@gmail.com [mailto:santiago.j.zar...@gmail.com] On Behalf Of Santiago Zarate Sent: Sunday, January 24, 2010 11:16 PM To: Don Muller Cc: dnsmasq-discuss@lists.thekelleys.org.uk Subject: Re: [Dnsmasq-discuss] Logfile rotation I would suggest you to use logrotate directly...: http://linux.die.net/man/8/logrotate 2010/1/24 Don Muller d...@djmuller.com: Hi, I just started using dnsmasq on my home network.

I strongly suspect that it closes its current file (by filehandle) and opens again the same name. Therefore you should relink (move/rename) the existing logfile beforehand so that the open attempt finds no existing file and creates a new one. On POSIX, you can rename a file which is in use and all open filehandles stay valid (writing the same file but with a different name from before, IOs to a file don't involve the name except for open itself). -Original Message- From: santiago.j.zar...@gmail.com [mailto:santiago.j.zar...@gmail.com] On Behalf Of Santiago Zarate Sent: Sunday, January 24, 2010 11:16 PM To: Don Muller Cc: dnsmasq-discuss@lists.thekelleys.org.uk Subject: Re: [Dnsmasq-discuss] Logfile rotation I would suggest you to use logrotate directly...: http://linux.die.net/man/8/logrotate 2010/1/24 Don Muller d...@djmuller.com: Hi, I just started using dnsmasq on my home network.

Jeremy M wrote: What will the broadcast address in the --dhcp-range configuration affect if not broadcast replies? The value of the broadcast address option sent to the client. This will eventually be installed in the client's network interface, along with the allocated IP address and the netmask. The broadcast address and netmask are optional in dhcp-range, since they are normally copied from the interface on the server which connects to the subnet the client is on. It's possible to omit them, except that the netmask has to be supplied when using a DHCP-relay, as dnsmasq can't determine it automatically. Don't forget that when the DHCP server is broadcasting to the client, the client doesn't yet know its IP address, so it can't respond to the network-broadcast address. Hence the use of 255.255.255.255 HTH Simon. On Sun, Jan 24, 2010 at 3:39 AM, Simon Kelley si...@thekelleys.org.uk mailto:si...@thekelleys.org.uk wrote: Jeremy M wrote: You were exactly right. The firewall was blocking outbound broadcast packets on the subnet. I'm not sure if this is correct, but my config specifies: dhcp-range=wireless,192.168.3.50,192.168.3.250,255.255.255.0,192.168.3.255,12h I think that's saying the broadcast address should be 192.168.3.255, but broadcasts attempts are actually going out on 255.255.255.255. 255.255.255.255 is always a valid broadcast address on IP networks, and the correct one to use for DHCP. 255.255.255.255 = limited broadcast address, propogates only on one network segment. 192.168.3.255 = network broadcast address. May be routed to other network segments be suitably configured routers. I'm glad that's fixed. Probably worth a FAQ entry! Cheers, Simon.

That's correct, but you may also have to create the new one and change its ownership/permissions so that dnsmasq can write to it. Remember that whilst running dnsmasq will probably not be uid=0 Cheers, Simon.
[Dnsmasq-discuss] basic host name problem
Hi, I've got a gateway server running dnsmasq for dhcp on my LAN and I've got a couple of problems with the host names of the dhcp clients. The first is a Belkin print server which picks up its ip address and passes thro its hostname MFD8FDC7. This appears in dnsmasq.leases - so I should be able to communicate with it now, right? There must be something missing from my dnsmasq config because I see now that any attempt to use the host names of dhcp clients from the gateway server fail with unknown host I'm on debian stable if that makes any difference. I've got 127.0.0.1 in my /etc/hosts 127.0.0.1 localhost isengard.localdomain isengard 192.168.0.2 isengard.localdomain # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts along with all that ipv6 stuff, which someone somewhere recommended at some point but I don't recall the details now (should I ditch it?) Plus this is the settings in dnsmasq.conf: adam@isengard:~$ decomment.sh /etc/dnsmasq.conf domain-needed bogus-priv filterwin2k server=/localdomain/127.0.0.1 local=/localdomain/ expand-hosts domain=localdomain dhcp-range=192.168.0.3,192.168.0.254 dhcp-option=option:router,192.168.0.2 dhcp-option=option:mtu,1500 Any inspiration gratefully received.
