dnsmasq not starting at boot

Freek

For some reason, dnsmasq isn't starting when I boot my VPS.
Every time I reboot my VPS, I have to manually type /etc/init.d/dnsmasq restart.
I already added '/etc/init.d/dnsmasq restart' to my /etc/rc.local file, but sadly doesn't make a difference.
How can I check why it doesn't start on boot?

Thanks

What OS?

Freek

That might've been handy to list indeed. Sorry about that!
Ubuntu 10.04.4 - 64 Bit on Xen.

Have you checked the logfiles for an indication?

NickM

Try adding it to the startup sequence properly first...

update-rc.d dnsmasq defaults

sleddog

Or if using dependency boot...

insserv -d dnsmasq

Freek

@nabo /var/log/boot is empty and /var/log/messages doesn't contain anything about dnsmasq.

@NickM. It seems like it has already been added to the startup sequence:
System start/stop links for /etc/init.d/dnsmasq already exist.

@sleddog I'm not using dependency boot afaik.

dnsmasq logs to /var/log/daemon. See your /etc/syslog.conf for details.

Freek

@nabo /var/log/daemon is empty, as well as /etc/syslog.conf :O ?

update-rc.d dnsmasq defaults?

Ubuntu changed it to /etc/rsyslog.d/50-default.conf. I though there still was more compatibility between Debian and Ubuntu. Apparently, not.

Freek

@TheHackBox @NickM already suggested that
@nabo Nothing to see there regarding dnsmasq...?

@Freek you can try start it when network is setup

create the file /etc/network/if-up.d/dnsmasq
with something like this:

#!/bin/sh
[ "$IFACE" != "lo" ] || exit 0
/usr/sbin/invoke-rc.d dnsmasq restart

and make it executable
chmod a+x /etc/network/if-up.d/dnsmasq

Freek

@prometeus Thanks, but again, 'computer says no'. I don't get it.. totally flabbergasted over here. Nothing to see in log files, it just doesn't start on boot. I have to execute 'service dnsmasq restart' manually after each and every boot to get it running....

sleddog

Put this in /etc/dnsmasq.conf:

log-facility=/var/log/dnsmasq.log

Then restart dnsmasq, confirm that the log file is created and has data.

Then see what's there when you reboot.

Freek

@sleddog Thanks for the help, appreciate it.
I restarted dnsmasq, the log file is created and has data:
Jun 12 03:19:58 dnsmasq[5696]: started, version 2.52 cachesize 150
Jun 12 03:19:58 dnsmasq[5696]: compile time options: IPv6 GNU-getopt DBus I18N $
Jun 12 03:19:58 dnsmasq[5696]: reading /etc/resolv.conf
Jun 12 03:19:58 dnsmasq[5696]: using nameserver 8.8.4.4#53
Jun 12 03:19:58 dnsmasq[5696]: using nameserver 8.8.8.8#53
Jun 12 03:19:58 dnsmasq[5696]: read /etc/hosts - 2 addresses

After rebooting my VPS, this was the only line that was added:
Jun 12 03:20:17 dnsmasq[5696]: exiting on receipt of SIGTERM
Which is invoked by the reboot command I guess... No signs of why it's not booting.

Recently had to reboot my VPS due to a datacenter migration. When it came back online, I was unable to use my VPN. Started to change all sort of settings, just to realize after an hour or so that I forgot that dnsmasq doesn't boot (for some reason) on startup.
So I'm giving this a bump because it's starting to annoy me now.

What does the init info at the top of the init script (/etc/init.d/dnsmasq) look like. Here's mine on Deb 6:

### BEGIN INIT INFO
# Provides:       dnsmasq
# Required-Start: $network $remote_fs $syslog
# Required-Stop:  $network $remote_fs $syslog
# Default-Start:  2 3 4 5
# Default-Stop:   1
# Description:    DHCP and DNS server
### END INIT INFO

And what does this show you...

cat /etc/init.d/.depend.start

Freek

Thanks for the reply @sleddog!

My init info at the top of the init script looks exactly the same, but here's it anyway:

`#!/bin/sh

BEGIN INIT INFO

Provides: dnsmasq

Required-Start: $network $remote_fs $syslog

Required-Stop: $network $remote_fs $syslog

Default-Start: 2 3 4 5

Default-Stop: 1

Description: DHCP and DNS server

END INIT INFO

`

cat /etc/init.d/.depend.start gives me:
cat: /etc/init.d/.depend.start: No such file or directory

That can't be good, can it?
Thanks in advance!

OK, forget that... guess your really are not using dependency boot.

Have a read at https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/876458

Post your dnsmasq.conf

Remove any reference to 'bind-interfaces' in the config.

I'm running out of ideas. I think it's a Ubuntu thing (upstart???) but I don't know Ubuntu well enough to say more.

If you want a hacky solution which does not fix your problem but might work:

Edit /etc/rc.local, add the daemon itself (dnsmasq -options) (not the rc.d script).

That did the trick!! Wohooo!! Thanks man!

Sadly did not work. dnsmasq doesn't seem to have a separate daemon. Luckily @sleddog suggestion fixed it! Finally!
