Set PuTTY defaults, permanently

PuTTY or one of its forks is a standard tool for administering Unix and Linux machines from Windows. It provides SSH connectivity for command line access, as well as keypair management for compatible programs like WinSCP.

Unfortunately, PuTTY has some terrible defaults. For example, it limits itself to 200 lines of scrollback by default, which guarantees that you’ll lose some history in most SSH sessions.

There’s a way to fix this and other defaults.

First, load the “Default Settings” saved session:1-load-default Then, configure the defaults as you like. For example, I’m increasing my lines of scrollback from 200 to 20,000: 2-configure

Then, save the new default settings:


PuTTY will now have a sensible defaults whenever you’re connecting to a random server.
