Negaduq

I've been using it for a long time and almost every day at one point or another. It's interface is fluid and easy to follow. There no fighting with termcap settings and genuinely for me it just works. It has a lot of features and support for things that I have not had a need to use on my ipad (port forwarding, pubkey auth for example) and really all the basic and not so basic features you would want with an SSH client. Anyone looking for a ssh client should really give this a go you won't be disappointed.
