DNSmasq status shows on Raspberry pi 4:

Jan 18 17:05:13 raspberrypi systemd[1]: Starting dnsmasq - A lightweight DHCP and caching DNS server...

Jan 18 17:05:13 raspberrypi dnsmasq[1122]: Too few arguments.
Jan 18 17:05:13 raspberrypi systemd[1]: Started dnsmasq - A lightweight DHCP and caching DNS server.

I am following the DNSmasq set up here. Nslookup and ping by host name on all the Windows and Linux clients suggest local DNSmasq nameservice is working.

The after <dnsmasq[1121]: read /etc/hosts> suggests a hosts file problem but it is just this :

127.0.0.1   localhost
127.0.1.1   raspberrypi

No changes were made to dnsmasq.conf. The only by default un-commented lines in it are :

hcp-mac=set:client_is_a_pi,B8:27:EB:*:*:*
dhcp-reply-delay=tag:client_is_a_pi,2

DNSmasq site specific commands are in /etc/dnsmasq.d/home.dns :

# General Configuration
domain-needed
bogus-priv
domain=xyz
dhcp-range=192.168.0.100,192.168.0.130,12h
dhcp-option=3,192.168.0.1
#
# Static IP Assignments
dhcp-host=90:A4:DE:8A:08:86,Onkyo,192.168.0.121
dhcp-host=D4:85:64:A8:EA:04,Manila,192.168.0.122

What might the too few arguments error be pointing at?

  • the last line says Started dnsmasq so, it's running - by the way I get the same error on all my pi's and I've made even less additions than you :p

  • The actual issue is something to do when openresolv is installed (which seems to be default on Raspberry Pi OS) - I have several servers all running debian, i.e. what Raspberry Pi OS is based on - and none of them have this "error" with dnsmasq - until I install openresolv

  • I see that openresolv can be uninstalled - but I don't know what I would be breaking.

  • when you uninstall openresolv, you can copy /etc/resolv.conf/bak to /etc/resolv.conf - if the former exists - otherwise, you just edit /etc/resolv.conf with entries appropriate to your needs - e.g. I have google nameserver entries in mine nameserver 8.8.8.8 and nameserver 8.8.4.4 - though on the pi, I also have nameserver 192.168.23.1 before the google ones - where 192.168.23.1 is my router address

  • What is the specific problem? I can't see any error message. The message you are worry about isn't marked as error. dnsmasq has exit status 0 (ok).

1 Answer 1

Reset to default
2

It seems that the Too few arguments is not a problem and can be ignored.
