Examples

Run a command on a remote machine using password authentication

  <sshexec host="somehost"
	username="dude"
	password="yo"
	command="touch somefile"/>

Run a command on a remote machine using key authentication

  <sshexec host="somehost"
	username="dude"
	keyfile="${user.home}/.ssh/id_dsa"
	passphrase="yo its a secret"
	command="touch somefile"/>

Run a command on a remote machine using key authentication with no passphrase

  <sshexec host="somehost"
	username="dude"
	keyfile="${user.home}/.ssh/id_dsa"
	command="touch somefile"/>

Security Note: Hard coding passwords and/or usernames in sshexec task can be a serious security hole. Consider using variable substituion and include the password on the command line. For example:

  <sshexec host="somehost"
	username="${username}"
	password="${password}"
	command="touch somefile"/>

Invoke ant with the following command line:

    ant -Dusername=me -Dpassword=mypassword target1 target2
