Hi Guys, can you please give some advise on a little problem that I'm facing, and maybe some confusion to?
I have a file/web server that I use to play with it, and it does not have a graphical desk top, after it boots it stays on a terminal mode waiting for commands.
i use ssh (putty) to login on the server from my desktop PC.
What i wanted to ask, is it possible to have all the commands that I'm typing on the ssh appear on the monitor that is connect on the server?
I searched to web trying to find something about that, but was unsuccessful, can you please give me some ideas?
i found a option to forward a session by using the option -X on ssh, but to use that would i have to have the x server installed on my server?
and if I do install it, would it make the server have a graphical desktop? I don't want to have the server to be graphical, I like it in terminal mode.
thank you.

Welcome back. Which distro is this for?

Kind of, but for what reason? The commands you run via PuTTY have the same effects as if they were run locally via the console on the server itself.

One way to have both your PuTTY terminal and the server's console showing the same output would be to use a terminal multiplexer like tmux. Most servers have it available by default, but if not you can install it with your package manager. After that, start a new session on the server's console:

Then use PuTTY from the other machine and log in to the same account. From there, attach to the established session:

There are a lot of variations on that theme. There is a lot more which can be done with tmux, so it has a lot of options and the reference manual "man tmux" is quite long.

About X11, it is the other way around. The X server is the graphical display and the programs you see and interact with are the clients. So it would be possible to run a graphical program on your server and have it display on your local machine by means of X forwarding. If you have a legacy OS you might have to add a package like Xming or XQuartz to have the prerequisite X server for that.

Which activities do you wish to do on the server?

For some ideas, check answers to the question How can I hook on to one terminal's output from another terminal? @SE U&L.

In that direction, once one knows the device of the terminal and the console, and one is using an advanced shell like Bash or Zsh, then tee can be used with process substitution and redirection to mirror from the PTS into both.

There, SSH is logged into some PTS and the console is active on TTY3. It will mirror any output from the PTS to the TTY but not vice versa. Although one can work in the TTY and nothing will show up in the PTS. So the TTY is not read-only. Read-only could be arranged in tmux with a little planning.
