Setting up the Project
We recommend using Maven to manage your Java dependencies. Instrutions and an example pom.xml are available in our article:
Executing Remote Commands
A common requirement of using a Java SSH API is to execute commands on remote servers. As an end-user, SSH has two separate mechanisms that can acheive this; you can start an interactive shell and type commands by just connecting to the server i.e.
ssh root@hostname, or you can execute the ssh command appending the command you want to execute to the command line i.e.
ssh root@hostname ls -l
Executing Single Commands
Executing Interactive Commands within a Remote Shell
It is often required that a command be executed under a privileged account using the Sudo command. This could prompt the user for their password, which presents a problem for many developers as the shell is just a stream of bytes and examining the command output for this can be problematic. Maverick Synergy has solved this problem with its ExpectShell implementation.
