It seems like everybody uses the free PuTTY client for accessing SSH
from Windows, but the lack of a tabbed interface has kept me using the
commercial SecureCRT application for years… until now.
With the PuTTY Connection Manager you can not only use tabs, but
also wrap PuTTY in a slick interface. The underlying client is still
the same putty.exe that you are used to… in fact the application
doesn’t even come bundled with it.
The first time you launch the application you’ll be asked to enter the location to your copy of PuTTY.
And finally, a tabbed version of PuTTY!
