This command, host -t SRV _ldap._tcp.sopranos.org.arpa gives me this error. Host _lda

Hello, y?all! Please keep it simple. I'm what I like to call a classic antique. Retired in '08.

Doing all this on a virtualbox, taking snapshots before each and every change. Trying to setup a domain controller on Linux Mint 22. Everything updated. (Always:)

I?m following these instructions: https://github.com/hortimech/Samba/b...ux%20Mint%2022

And each and every time I get to this same spot, and I get the same results.

sudo smbclient //localhost/netlogon -UAdministrator -c 'ls' Password for [SOPRANOS\Administrator]: . D 0 Wed Oct 9 15:15:08 2024 .. D 0 Wed Oct 9 15:15:08 2024
50770432 blocks of size 1024. 36740828 blocks available

At this point, I?m good.

At the very next step, I?m not. I?ve restored snapshots 4 times, with the same result.

host -t SRV _ldap._tcp.sopranos.org.arpa Host _ldap._tcp.sopranos.org.arpa not found: 3(NXDOMAIN)

No A records either. I tried a few things I found on google, and I couldn?t even get onto the web afterwards. I could ping 8.8.8.8, but not google.com.

sudo kinit Administrator [sudo] password for richie:
kinit: Cannot find KDC for realm "SOPRANOS.ORG.ARPA" while getting initial credentials

My hosts file:

127.0.0.1 localhost
192.168.1.206 ra.sopranos.org.arpa ra
The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters

Do I even need that "stuff" for IPv6? I disabled it. Don't need it, don't want it. Just clutters things up.

See that? IPv6 just clutters things up.
