Hello,
We have many Production & Pre-Production AIX boxes. I wanted to set default background color of all Production boxes so any of the user who connects remotely using Putty or other SSH client to Production boxes can distinguish it clearly.
I know I can use Putty settings to achieve this but there is no guaranty that all other users would do it.

I tried playing around with xterm settings (setb/setf) in terminfo directory but dint had any luck.
Can anyone please help me out on this?

Thanks

You might try using the following thing in the users' .profile
echo '\033[41;97m'

I have tried this but the problem is if I re-size the Putty window from full screen (maximized) to some other size and back again to full screen, background color doesnot expand and have to issue clear command every time.

That I guess will be irritating for all users.

I think the background colour should be on all places where there is output written on the terminal or where the user types something... if this isn't good enough I'll be interested in your solution

yes, that's the difference between teletype style and fullscreen style user interfaces.

you can use different putty profiles and manage colors therein
OR only color the prompt (PS1)
OR use X11 xterm

AND get back to more important tasks ;-)

peace

Hi,

I am not sure which version of PuTTY you are using, but using version 0.60 and vt100 emulation, I am not having this problem. I can change screen size and the entire screen is the same background colour. You may need to examine the Putty settings and ensure that for "When window is resized:" the radiobutton "Change the number of rows and columns" is selected.

I have a number of shell scripts which cycle continuously and which use the "termdef -c" and "termdef -l" requests to determine screen size, and then adjust the output accordingly. Most of these then use the vt100 escape sequences to change the screen colours. Nothing too fancy.

If the Putty setting "Terminal - Use background colour to erase screen" is set, then the screen will clear to the background colour. This makes the background colour transmitted by the host fill the entire screen, and not just the echoed text.

You may consider setting the screen background colour in /etc/profile or /etc/motd but you must then 'clear' the screen for it to work.

It is possible with tput command.

• 0: Black
• 1: Blue
• 2: Green
• 3: Cyan
• 4: Red
• 5: Magenta
• 6: Yellow
• 7: White

Try below command to change background:

tput setb 4               -------> 4 for Red

Try below command to change foreground:

tput setb 4            --------> 4 for Red

Hope this info help much...

What if you include the ANSI escape code in the PS1 prompt? At least after the user hits enter, it will be reset to the proper color. It's not perfect, but it might be good enough.
