Nice but too many ads
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.
As always, awesome explanation.
Love from INDIA. 🙏🏻
That's awesome video Jay. You are the coolest Linux teacher in the Universe. Respect from Poland.
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
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).
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.
i have struggled with this for a long long time!!
thank you for doing this video.
I install AD, because it is the best admin tool. After installation, I have the capabilities of a network device manager.
Crap video, too much sponsored content.
Hello there, is your playlist on how to configure Ubuntu server from the get go you uploaded few years ago not available anymore?
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?
Can you explain assigning a fqdn without a domain controller?
This has answered so many questions I've had about domains! Please make more videos on this!
how do you download ct template from promox to pc if can how if no why can't it allow to download
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?
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.
Please make a video about Two-Factor Disk-Encryption, with Yubikey, FIDO2 or something like that.
I'm guessing an IT guy connected wrongly to the shinra server is probably what took down the midgar plate.
Thanks Jay.
That was the perfect balance and agree to going into no more detail than was strictly necessary without going off topic.
