Poderosa: A Viable Alternative To Putty
Anyone who needs to ssh to or script scp copies from Windows to *nix hosts knows about putty. It is practically the de-facto standard since it works flawlessly (insofar as a software program can be flawless) and is not just free to use, but is also open source.
While the individual programs provide high-utility, it does not meet everyone's needs. In the past, I have tended to use Xshell from NetSarang when connecting to my Linux, Solaris, FreeBSD and OS X hosts from my Windows boxes, but haven't kept up with the license purchases and have defaulted to putty ever since, all the while missing my tabbed terminal window.
Enter: Poderosa. Since it is at version 4, I have no idea how I missed up until now, but it is a full-features ssh terminal (with tabs!) that does almost everything you might need. It supports ssh keys (and has a decent keygen interface) and has a decent selection of terminal preferences. It has built-in support for cygwin shells and provides some nifty extra features (command auto-complete, command-output pop-up display) in the event you do any work with cygwin.
Poderosa, like it's putty cousin, is fully open source as well as free to use and is extensible through a fairly robust plug-in architecture. It lacks ssh port forwarding and the ability to scp files, but it has enough features that it will supplement the putty utilities for me (how can I *not* keep putty with me on my USB thumb drive) quite well from now on.
