Download this app if: you need an open-source Secure Shell (SSH) client.
ConnectBot is a powerful open-source Secure Shell (SSH) client. It can manage simultaneous SSH sessions, create secure tunnels, and copy/paste between other applications.
This client allows you to connect to Secure Shell servers that typically run on UNIX-based servers.
Pretty much the best free SSH client out there — The only tricky part is using the software without a hardware keyboard. I found I had to use the swype keyboard and access the arrow keys to make it useful for accessing bash shells. That, and learning the alternative Ctrl-key sequences is a must. e.g. Ctrl+i for a tab needed for tab-completion.
