Different console background for different servers?

Question

SSH

Good day, Habr!
I think each of those who use the built-in ssh console client from under Linux at least once got confused and executed a command on the server that should have been on the local machine or vice versa, or even confused the server. In general, you understand what I mean;)
Any ideas how to recolor the background of the console so that it is acceptable for server A it was black, server B is gray, etc.

Answer 1

Make different prompts on different servers, then this setting will be independent of the terminal emulator used. For example, [19:13:13; [email protected]; dir]$you can highlight [email protected] in different colors.

Answer 2

In my opinion, it is enough to enter the server name in PS1:

\[\033[1;33;41m\h>\]\[\033[1;32;40m \D{%d.%m, %H:%M}\] \[\033[1;33;40m\w\]\[\033[1;32;40m\]\[\033[0;37;40m\n

And the color can also be changed using the PS1.
It is convenient to select the desired colors using the script:

Answer 3

5 servers in tabs and get the dream of an epileptic. :)
I use "[lapatopa frol:~]$" coloring for the welcome font color, usually green + machine name highlighted in red/yellow (in this case, lapatopa is my local laptop, so I have it green). On production servers, I have the server name highlighted in red :)

Answer 4

I don't have many servers. I work out by setting up Profiles in the Gnome Terminal.
The command for each profile is ssh [email protected]
On the Colors tab, you can customize the look you want.

Answer 5

Maybe it will help:

$ setterm -foreground green -background black -store

If it works, then add it to .bashrc (well, or which shell you use) and that's it.
PS
There is a doubt that it will not work (for example, run top , and it will take yes and change all the colors back), but I can’t check: there’s nothing.

Answer 6

besides displaying the server name in the prompt, I also highlight different tabs for different machines: 3-local, 4-production-server

Answer 7

I once used this:
ssh () { echo -ne '\033]50;colorscheme=BlackOnWhite\a'; =ssh $*; _exitcode=$?; echo -ne '\033]50;colorscheme=Linux\a'; return $_exitcode }
Sharpened for konsole / yakuake, allows you to distinguish the local machine from ssh.
