    This has answered so many questions I've had about domains! Please make more videos on this!

    Thanks Jay.
    That was the perfect balance and agree to going into no more detail than was strictly necessary without going off topic.

    MS Domain controller AD is based on three software/protocols which Kerberos, LDAP and CIF (which is SMB and implemented in Samba in Linux). And they also usually have a DNS server, but that can also be another software in Linux.
    (Use Kerberos for single sign on and verify machines AND users, LDAP for search databases for machine names and user names etc and CIF for send scripts to machine to set up software).

    Sometimes after a reboot, the old hostname persists. I had to change the file /etc/cloud/cloud.cfg. There is a setting preserve_hostname: false. I had to change this to true and the new hostname survives a reboot.

    I'm guessing an IT guy connected wrongly to the shinra server is probably what took down the midgar plate.

    If you are working on a server in a terminal how do you know what the full domain name of that server is? Can it be displayed in the bash prompt as an alternative to the host name?

    Great video! I have two questions about domain controllers: 1) What is an example of a domain controller other than Active Directory by Microsoft? 2) What use does a domain controller have for managing systems not running Windows? Thanks for posting!

      Think you would be looking at OpenLDAP or similar.
      Would love to see a video going over this (if there isn't one already)

    Please make a video about Two-Factor Disk-Encryption, with Yubikey, FIDO2 or something like that.

    I install AD, because it is the best admin tool. After installation, I have the capabilities of a network device manager.

    What is the smartest/safest way to mount a server files on different class c. Situation I have spun up a linode server, but not reachable for an employee in the country he is in.. but he can spin up a cloud instance in the country he is in, and from within this server he can shell into my linode instance. He is looking to permanently mount one of my directories.. I am think even secure nfs is not that secure.

    I'm a hint disappointed in this video just cause I feel like I have more questions now.
    Is the domain name for a computer set by the computer itself? Or by some network setting?

    • @noweare1

      You actually have to purchase a domain name. I agree this was not his best presentation but he does have the best videos overall. Basically I think of domain name as a human readable substitute for an ip address.

    Can you explain assigning a fqdn without a domain controller?

  • @Theborg72

    hi, really interesting but got a thought
    in case you do not have a domain controller. how do you then set it up so it finds the right server with domain requests

    After becoming a fan of Steven Universe (simultaneously the most exciting and disappointing series I've ever watched) I started naming servers after types of gems. Mythological pantheons is also a scheme I've used.

    Please I need help, how to associate hostname to IP address

  • @canadianwildlifeservice8883

    I can't post a link as an example or else my comment gets deleted, but why didn't he explain the concept of subdomains when discussing a FQDN? He mentions hostnames, and domain names, but not subdomains. Subdomains are the beginning part of a domain name, which is necessary for dynamic DNS, which is basically a domain name with a subdomain name in front.

    They are data objects or source if you don't care about author's right on data which is illegally obtained. I don't care about authors in this context.
