One of my top five must-have apps for the iPad was an SSH / terminal app. In my goal to be laptop free on trips away from home, a terminal app that I could use for SSH connection to my various work servers was a priority. Although I don't need terminal access all the time, I do use it to do some quick things via command line, and often times it's been a life saver. In the past, an SSH app on my iPhone proved to be invaluable as I've been able to do so many things remotely via command line. Although using any terminal app via the iPhone is not ideal because of the tiny screen, it sure does come in handy when you're in a bind and have to do some quick fixes remotely. This along with a VNC client would be a wonderful boon to any traveling System Administrator, especially if it worked on the iPad! Lucky for us, there's iSSH.
The good folks at Zingersoft were kind enough to allow us to test drive their iSSH 
app which originally came out on the iPhone, but has now been upgraded to take advantage of the large screen on the iPad as well. I hadn't used iSSH before but heard great things about the iPhone app through other friends who do use it. I had been using pTerm on my iPhone, in case you were wondering.
iSSH has a whole ton of features. In fact, so many features that I honestly don't know how (or don't need to) to use them. Here's a good comparison list of iSSH vs other Terminal type apps just to give you an idea of how feature rich this app is. Not only does iSSH do VT100 emulation, SSH, ANSI/Color/Xterm and telnet, it can also do VNC too!
As I stated earlier, my use for SSH connectivity is very minimal and I rarely need more than just plain SSH and VT100 emulation. Getting things up and running was quick and easy in iSSH. Click on Add Configuration and fill out the connection information on the screen. iSSH allows you to ask for your password each time you connect, which I think is a great feature. Wouldn't want anyone taking over one of my computers via any app if the iPhone or iPad was ever stolen!
Once connected you should be transported to familiar territory as iSSH will look just like any other VT100 terminal. In portrait mode, iSSH has a split screen, which might be useful to a lot of folks who need this capability. There was currently no way to turn this off, but according to iSSH's support forum, the next update will have support to configure this feature. In landscape mode, you get full screen view of the terminal with a translucent keyboard overlaid. You can toggle the keyboard to be translucent, solid or hidden. I use this mode the most since it's the easiest for me to type on. It took a while to get used to typing on the translucent keyboard, but once I was accustomed to it, it felt like home. The next release should allow you to set the terminal size so folks who don't like the translucent keyboard can work happily.
You can also connect to any machine that has a VNC running. To test this out, I went and turned on VNC sharing on my MacBook Pro. From here I was able to control my Mac in real time on the iPad's really large screen. Once in VNC mode, there is a hovering panel that allows you to do the arrow keys, standard iPad keyboard as well as left and right mouse clicks. I wasn't quite sure how to get the keyboard to do any control or command keys though. So far, the current version of iSSH doesn't let you use a bluetooth keyboard or keyboard dock, but this will be fixed in an upcoming release. Having VNC functionality embedded into iSSH is a real plus for this app.
I think iSSH helps me take a huge step toward never needing to carry around my MacBook Pro with me on trips. As I mentioned earlier, there are far more features to this app than just what I've been able to wrap my brain around. If you're looking for an SSH client for iPad, this is the ONE! iSSH - SSH / VNC Consle is available in the iTunes App Store.
This app is a must have for me too!
By the way, that's some serious uptime on that server in your screenshot!
Heh. Yeah it is. Maybe you can help me fix that, no?
Can you do X forwarding so you can bring the display portion of apps to your iPad without having to do VNC?
VNC has its usefulness, but it is not anywhere near as good as running the X server to display a remote application written to xlib.
I'm not sure if it can do exactly what you want it to do, but it does work with X. See here: http://www.zinger-soft.com/support_a_4.html
