comment Setup a common /opt such that both my Linux Distributions can use it
Possible, but you'd have to skip all the usual package management on either distro and do manual installs of pretty much everything -- and then keep the dependencies sorted and parallel on your own as well. Good luck.

comment How can I test if a file in /root exists without su to root?
@user164825 If a non-root user has read access to /root/, something has gone very wrong with your system setup.

The issue isn't with the file 1.txt, it's that root's home directory isn't world-readable and really shouldn't be.

Note that in virtually all distributions worth the name, loopback is already configured out of the box.

In a pinch you could probably netcat the digital in/out ports....

comment n-factor SSH authentication for CentOS 7
@Codemed to clarify: 2FA is not a bad idea, and there is no reason it can't be done well. The way you're trying to do it isn't it, though; this answer attempts to point you in the direction of something that is likely to work.

comment n-factor SSH authentication for CentOS 7
@codemed Just because you don't like being told that your original question was poorly informed doesn't mean this is a bad answer. The "instructions" you ask for don't exist because the way you say you're trying to set things up won't work. You were trying to use GCC to compile a shell script, for cryin' out loud.

Debian does not automatically install a webserver unless you tell it to during installation. If you want to run one, use apt-get install apache2 or apt-get install nginx or apt-get install lighttpd, as per taste.

Then you don't have anything listening on those ports, which is why you get connection refused.

Do you actually have anything listening on that port? Say, apache or nginx or lighttpd ? Use the netstat -pat command to see what if anything is listening on which TCP port(s)

@muru Out of curiosity, why not?
