What is Solar-PuTTY?

GNS3 uses Solar-PuTTY as the default terminal software, a tabbed terminal software based on PuTTY. Solar-PuTTY’s default window is an orangeish font color on a black background.

Personally, I don’t like the background color and font color. If you try to change the background color or font color, you may be confused as to how to do so. (I was so confused that it took me about 3 hours of research and trial and error to change the font and background color…)

How to change the background color and font color on Solar-PuTTY is explained.

Step3:Save the “Default Settings”

This is the confusing part. When you click [Open] on the [PuTTY Configuration] page, the changes are not reflected. You have to save the “Default Settings” in order for the font and background color settings to take effect. Go to Session and select “Default Settings” and click [Save]. This will save your changes. After that, you can close the screen by clicking [Cancel].

Step4:Reconnect the console

If you connect to your router’s console again, the font and background color changes will be reflected.
