At my job, I ssh into a development server everyday. I usually use exceed XStart to ssh in, but I downloaded PuTTY to see if I could do anything that I couldn't do with XStart.

I spend almost the entire day looking at the regular white background/black text terminal. The TERM variable in the server is set to vt100, and as far as I know, it's an eight-color display.

I was wondering if there was a way to have PuTTY emulate a 256 color terminal. I would really like some syntax highlighting in Vim, and the built-in ones are just awful. I've tried vim -T xterm-256color, and that only seems to let me use the default color schemes.

I also tried setting t_Co=256, but that doesn't work either.

If it helps, the dev server is a Red Hat 6 box.

1. Configure Putty

In Settings -> Windows -> Colours there is a check box for "Allow terminal to use xterm 256-colour mode".

2. Let the app know

You'll probably have to change Settings -> Connection > Data > Terminal-type string to "xterm-256color".

I have just verified that I can get 256 colors in Vim with PuTTY when that option is enabled. PuTTY seems to set the TERM to "xterm" automatically for me; you may still need to manually do ":set t_Co=256" within Vim. –  Heptite Jun 14 '12 at 17:48
    
I tried the Allow xterm 256-color mode, and that hasn't done anything. I also changed the terminal string to xterm-color, that also did nothing. –  Tom Jun 14 '12 at 19:54
    
@Tom the terminal should be xterm-256color –  bahamat Jun 14 '12 at 21:46
    
@bahamat: good catch, I'll update the answer. –  RedGrittyBrick Jun 15 '12 at 0:10

@Tom: All other systems that I've used use xterm-256color. If putty doesn't do anything with that I'm not sure anything else can be done. Check this page: http://www.frexx.de/xterm-256-notes/ and try the 256colors2.pl script to determine for sure wether or not it's working. –  bahamat Jun 15 '12 at 18:10
