Re: Here there be Dragons!

I'm not a Linux expert. (I have Xbuntu installed on a throwaway, 9 year old, 3 gb laptop for educational purposes. And maybe games for grandkids.)

SU was a new one to me. FWIW, here's a note I found about it:

Ubuntu was the first widely used Linux distribution that adopted sudo-only approach by default. When one installs Ubuntu Linux, the root account is created without any password. One needs to assign a password to the root account to log in as root. In Ubuntu and many other Debian-based distros, the user needs to remember just a single password. This way, Ubuntu encourages a user to avoid logging in as a root user. In distros like Fedora, a person needs to create different passwords for root and user accounts.

Yes, using Virtual Box.  Using an older Ubuntu (16.04 LTS) and yes, it has sudo, but not su.  So you can execute one command at a time as root, but you can't get into "root mode".

Are you building the virtual machines on top of Microsoft Windows?  If so, are you using Oracle Virtual Box, VMWare, or something else?

Doesn't Ubuntu have a Sudo command?

Don't get lost...

Okay, folks, I'm beginning a dark, dangerous journey.  I just wanted to leave notice in case I disappear; a search party may be needed. My goal is to create a network of interconnected Linux machines, all of which can be accessed by API from anything (including the IBM i). To that end, I'm installing LAMP stacks on Ubuntu virtual machines and trying to get them to talk to one another.  I'm learning acronyms like LTS and SSH and PDT and strange incantations like /etc/network and php7.0-curl.

I've already got several VMs created.  And I could swear that new ones are popping into existence without my intervention. But it just might be late night hallucinations.  Anyway, don't be surprised if you hear strange noises from this part of the world.

Here there be dragons...
