| <h3>Examples</h3> |
| <p><b>Run a command on a remote machine using password authentication</b></p> |
| <pre> |
| <sshexec host="somehost" |
| username="dude" |
| password="yo" |
| command="touch somefile"/> |
| </pre> |
| |
| <p><b>Run a command on a remote machine using key authentication</b></p> |
| <pre> |
| <sshexec host="somehost" |
| username="dude" |
| keyfile="${user.home}/.ssh/id_dsa" |
| passphrase="yo its a secret" |
| command="touch somefile"/> |
| </pre> |
| |
| <p><b>Run a command on a remote machine using key authentication with no passphrase</b></p> |
| <pre> |
| <sshexec host="somehost" |
| username="dude" |
| keyfile="${user.home}/.ssh/id_dsa" |
| command="touch somefile"/> |
| </pre> |
| |
| <p><b>Run a set of commands from a command resource (file) on a remote machine using key authentication with no passphrase</b></p> |
| <pre> |
| <sshexec host="somehost" |
| username="dude" |
| keyfile="${user.home}/.ssh/id_dsa" |
| commandResource="to_run"/> |
| </pre> |
| |
| |
| <p><strong>Security Note:</strong> Hard coding passwords and/or usernames |
| in sshexec task can be a serious security hole. Consider using variable |
| substitution and include the password on the command line. For example:<br> |
| <pre> |
| <sshexec host="somehost" |
| username="${username}" |
| password="${password}" |
| command="touch somefile"/> |
| </pre> |
| Invoke ant with the following command line: |
| <pre> |
| ant -Dusername=me -Dpassword=mypassword target1 target2 |
| </pre> |
