34 <para>
35 The <application>ssh-askpass</application> is a generic executable name for
36 many packages, with similar names, that provide a interactive X service to
37 grab password for packages requiring administrative privileges to be run.
38 It prompts the user with a window box where the necessary password can be
39 inserted. Here, we choose Damien Miller's package distributed in the
40 <application>OpenSSH</application> tarball.</para>
