Issue with Dnsamasq when adding a static lease

Hi All

I am getting this error when adding a new static lease

dhcpleases		Could not deliver signal HUP to process because its pidfile (/var/run/dnsmasq.pid) does not exist, No such process.

Running version 2.3.2

the pid file does exist and contains a process id

-rw-r--r--  1 root  wheel       5 Aug 27 16:31 dnsmasq.pid

The new static lease is not recognised meaning the new device does not get an IP (as only listed devices get IPs)

Any help appreciated

Upgrade to current.

I have upgraded to current and the issue persists. Any other suggestions?

Sure.

Start by detailing your setup.
pfSEnse, by default, uses the Resolver (unbound). Not the Forwarder (dnsmasq).
What are you using ?

When you add a static lease, are you doing this here : Services => DHCP Server => LAN

Sorry for the silly questions, I'm trying to do what you do.
I just witched to the Forwarder, DNS, checked that it worked = resolved, and added a static lease. Didn't saw any errors.
So, what else did you take from default ? ;)

Hi

Thanks for the reply.

Current Base System 2.4.3_1

Using Dnsmasq as the forwarder - not using a DNS resolver

To add a static lease Service -> DHCP server -> LAN

Add all necessary details and then apply changes. When I look at system logs I get errors mentioned above

Since my upgrade to current release there are a few more messages

Did you accessed the console and checked :
/var/run/dnsmasq.pid does not exist ?

Also : while you're in console mode, run a
ps ax | grep "dnsmasq"
(or whatever the process name of dnsmasq is.

It should run, because : if not, no more DNS ....

Btw : why the Forwarder ?
And, because it takes 1 minute to activate the Resolver : less problems / more problems ?

/var/run/dnsmasq.pid

Yes file exists and process id matches Dnsmasq

[2.4.3-RELEASE][admin@gw.genepool.private]/var/run: cat dnsmasq.pid 
94419
[2.4.3-RELEASE][admin@gw.genepool.private]/var/run: ps ax|grep dnsmasq
94419  -  S        0:25.69 /usr/local/sbin/dnsmasq --all-servers -C /dev/null -
16940  1  S+       0:00.00 grep dnsmasq

We have a corporate DNS server, so don't wish to resolve addresses (or block any) just forward them on.

This setup has been running for some time like this, however errors are new.

The issue existed .... a long time ago (Google and forum.netgate.com are my sources).
You restarted pfSense after upgrading ?

I'm using the Forwarder right now and leave it there for a moment. Didn't see any "pid" errors ... yet.

Btw : the error (see your first post) might be correct : check with the logs Status => System Logs => System => DNS Resolver if dnsmasq wasn't restarting at that very moment.

Now when I restart dnsmasq I get

/services_dhcp_edit.php: The command '/usr/sbin/arp -d '192.168.170.239'' returned exit code '1', the output was 'arp: writing to routing socket: No such file or directory'

I actually opened a separate ticket about this - but obviously they are connected
