macos 13.5 (Ventura) : "host" & "nslookup" commands can resolve the local domain, but ssh & safari can't connect to host

Inside my network I have DNS server which controls local domain nucme. The command host can resolve the domain name:

administrator@iMac-1 / % host 123.nucme

123.nucme has address 192.168.1.22

and nslookup command works well:

administrator@iMac-1 / % nslookup 123.nucme

Server: 192.168.1.22

Address: 192.168.1.22#53

Name: 123.nucme

Address: 192.168.1.22

But when I try to connect to 123.nucme over ssh:

administrator@iMac-1 / % ssh user@123.nucme

ssh: Could not resolve hostname 123.nucme: nodename nor servname provided, or not known

The ping command does not work as well

administrator@iMac-1 resolver % ping 123.nucme   

ping: cannot resolve 123.nucme: Unknown host

Why? I flushed DNS cach and restarted DNS daemon on my mac:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder

Apple support has not helped me at all. They said to connect me with senior manager but it takes a while.

Solution:

open terminal and run the followin commands:

• if your system does not have /etc/resolver folder:

sudo mkdir /etc/resolver

(the system will ask your password)

• echo 'nameserver ip_address_of_your_nameserver' | sudo tee your_domain

Now you can check if your domain can be resolved:

administrator@iMac-1 resolver % scutil --dns

DNS configuration

resolver #1

 nameserver[0] : 192.168.1.1

 nameserver[1] : 192.168.1.22

 nameserver[2] : 192.168.2.22

 nameserver[3] : 1.1.1.1

 nameserver[4] : 8.8.8.8

 nameserver[5] : 8.8.4.4

 flags  : Request A records

 reach  : 0x00020002 (Reachable,Directly Reachable Address)

...

resolver #8

 domain  : nucme

 nameserver[0] : 192.168.1.22

 flags  : Request A records

 reach  : 0x00020002 (Reachable,Directly Reachable Address)

Now you domain can be resolved.

administrator@iMac-1 resolver % ping 123.nucme
