When configuring a bunch of devices (switches, routers or even computers), most of the configuration will be identical. The Konsole program of KDE has a nice feature which sends the keyboard input to all open tabs. By simply telnet-ing or ssh-ing into the devices and activating this feature, I can quickly configure them all at once.
At work, using my Windows laptop, I have been looking for a feature like this. After some googling I foundIt’s a standalone application which emulates this behaviour: It sends emulated keypresses to all (or a subset of) open putty sessions.
Configuring 8 blade-switches with PuttyCS is a breeze: just open all the putty sessions and start typing in PuttyCS!
