Hello,
I'm using dnsmasq as part of the LEAF (uClib) firewall application on
sourceforge. The project recently moved to using version 2.26 of
dnsmasq, and that version is not working for me, where 2.24 works fine
with an identical dsnmasq.conf file and on an otherwise identical LEAF
system. After I tried version 2.27 with the same results, the LEAF
folks suggested I forward details to this group.
I rebooted my router (a WRAP board from PC Engines) at 10:43 pm last
night, at which time dnsmasq started. This morning dns was down, and
I looked on the router.
[chloris 07:12:50]~\: ls -l /var/run/dnsmasq.pid
-rw-r--r-- 1 root root 6 Mar 31 22:43 /var/run/dnsmasq.pid
dnsmasq is no longer running, and I don't see anything in the logs to
indicate why it died:
[chloris 07:26:49]/var/log\: ps -ef | grep dns
13082 root 300 R grep dns
[chloris 07:26:58]/var/log\:
(After restarting it, I see this:
[chloris 07:41:37]/var/log\: ps -ef | grep dns
13280 nobody 364 S /usr/sbin/dnsmasq
)
One of my hosts renewed its lease successfully at 10:47 pm last night:
Mar 31 22:47:38 bimmer dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67
Mar 31 22:47:38 bimmer dhclient: DHCPACK from 10.21.21.254
It tried again, and failed, at 11:17 pm
Mar 31 23:17:38 bimmer dhclient: DHCPREQUEST on eth0 to 10.21.21.254 port 67
Mar 31 23:18:24 bimmer last message repeated 3 times
The 22:47:38 DHCPACK above is the last in the logs. There are more DHCPREQUESTs and then
Mar 31 23:48:36 bimmer dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
Mar 31 23:48:40 bimmer dhclient: No DHCPOFFERS received.
(My daughter reports that the internet "stopped working" at about
11:20. She was using bimmer.)
Another of my hosts renewed its lease successfully at 10:51. But when it
tried again at 11:21 it failed.
Here is the entire /var/log/daemon.log on the router, "chloris", up
until the last entry from dnsmasq:

Chloris has plenty of memory. That's not why dnsmasq died.
[chloris 07:26:58]/var/log\: free
total used free shared buffers
Mem: 127724 10784 116940 0 44
Swap: 0 0 0
Total: 127724 10784 116940
There's also plenty of ram "disk" space:
[chloris 07:42:02]/var/log\: df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/root 10240 5820 4420 57% /
tmpfs 10240 28 10212 0% /tmp
tmpfs 10240 80 10160 1% /var/log
That's all the information I can think to give you now. Please let me
know if there's anything else. I'll have to restart dnsmasq in order
to send this mail, but it dies pretty reliably several times per day.
I'm available for the next four days, but after Tuesday will be
traveling and so must re-install the older dsnmasq since I'm the only one
here who can restart it on the router.
Thanks,
