Hi I have network at a school setup with

  1. pfsense as firewall, router, dhcp and captive portal (for wifi), domain: schoolname.intranet
  2. zentyal: freeradius, ldap, dc, and dns

problem:

clients can't resolve hostnames into ip address, I tried and hostname.schoolname.intranet but neither work.

Business need:

I wanted to be able to use the hostname in veyon so I can have a master computer (teacher's) being able to see other computers on the network and manage them from that master computer, I wanted to do this using the hostname as opposed to the ip address.

some details

  1. there are two networks: 10.20.20.x (wired, pfsense: .1, zentyal: .24 ) and 10.30.30.x (wireless)
  2. client internet connectivity and dns external resolution works fine
  3. dns server issued through dhcp for dhcp clients is 10.20.20.24 (zentyal server)
  4. dns forwarder is enabled in pfsense
  5. zentyal'dns has a forwarder: .1 (pfsense)

if I do dig <hostname> @<pfsense or zentyal ip> it resolves fine

but if I do dig <hostname> I get no resolution

here's sample of a hostname: clementesepxx

fcortxx@benedictoxx:~$ dig clementesepxx

; <<>> DiG 9.16.1-Ubuntu <<>> clementesepxx
;; global options: +cmd

here's the ping command for same hostname from the same client

fcortxx@benedictoxx:~$ ping clementeseptimol
ping: clementesepxx: Temporary failure in name resolution
fcortxx@benedictoxx:~$ ping clementeseptimol.schoolname.intranet
ping: clementesepxx.schoolname.intranet: Name or service not known
fcortxx@benedictoxx:~$ 

any guidance or help is appreciate it.

    Your question is mostly offtopic here as not related to a business setting. But: 1) ping is not an adequate tool to troubleshoot DNS 2) Do not put data needed to understand your question in some remote link that can go stale, put everything needed in your question 3) dig without @ queries the locally configured recursive nameserver, which seems to be 127.0.0.53 based on your trace... which is typically the address uses by systemd-resolved so look at it. It says SERVFAIL which should appear in logfiles, as it is a sign of misconfiguration of something. Jul 25 at 16:41
  • Thank you @PatrickMevzek for the feedback. I've added the pics of my pfsense config and some info about why I need this as a business setting. This afternoon I'll check out the logs as you suggested to see if I can spot something to change. Jul 26 at 18:38

this more like a work around but it's been the solution for now that I have now adopted to my problem/issue:

I ended up setting up static mappings on my pfsense box: Under status > dhcp leases, I went ahead and found the boxes that I needed to have a predefined Ip address and I clicked on the plus sign in order to setup static dhcp mappings, I used addressed outside the dhcp pool previously configured for said network.

now on veyon I can use ip addresses instead of hostnames (which I think it's better in the long run instead of hostname to ip lookups)

source: static DHCP mappings
