Save modified settings in a named session.

Before you start to make any changes in Putty, a named session should be created so said changes can kept for future use. Under this session you may also save the connection type and host name of the destination. The host name or IP address and port number can be entered in the box labeled "Host Name (or IP address)" and "Port". One of five connection types can be selected from the section labeled "Connection Type". Once these have been set, in the textbox under "Saved Sessions" enter a name for the session be stored as. Then click on the save button. See Box 1.


Box 1.

To restore these changes after changing sessions or exiting Putty, select the saved sessions from the "Load save, or delete a stored session" and click the "Load" button.

Change the terminal font.

Look in the box on the left and find the Category named "Window". Then click the sub-category "Appearance". Next, find the "font settings" section and click on the "Change" button to modify font settings for the current session. See Box 2.


Box 2.

Once there, choose a font family, style and size for Putty to use and select "Ok". See Box 3.


Box 3.

Return to the starting window by selecting the "Session" option under category, then click the "Save" button to save the changes to the font for the current session.

Change various coloring formats.

This section will describe how to change color properties on Putty's terminal window. Travel to the "Colours" category under "Window" on the left hand side. There you will see multiple settings with color properties in the RGB format to change. To change one, click on the property you'd like to change, such as "Default Background", and modify any combination of the red, green and blue values or click on the modify button to choose from a color palette. See Box 4.


Box 4.

Return to the "Session" category and click on the "Save" button to store these changes to the current session.

There are numerous options to change, so its worth experimenting with the colors to produce a unique terminal experience. As you can see, my session is looking fabulous.


Modify lines of scroll-back.

To change the amount of lines of scroll-back within the Putty terminal, first travel to the category "Window". On this view is a section titled "Control the scrollback in the window". Enter the value you would like to change it to. For example, 20000 lines of scroll-back gives more lines of output than the default value of 200. See Box 5.


Box 5.

Travel back to the "Session" category and click on "Save" to store these changes to the current session.

Setting an auto-login username.

To give Putty a username to automatically use when connecting, first travel to the "Connection" category on the left, then to "Data". In the section named "Login details", there is a place to enter the desired auto username across from the section named "Auto-login username". See Box 6.


Box 6.

After entering a username, travel to the "Session" category and click "Save" to store the default username to the current session.
