The modules collected herein provide perl classes which I base further projects on.
This perl module contains several useful functions for the statistical analysis of a series of measurements. These were implemented during my diploma thesis to.
The ssh-add utility (see SSH agent for details) accepts a program in the environment variable SSH_ASKPASS that retrieves a passphrase from the user. This is especially useful to use the SSH agent from a script or a GUI (i.e. without a console).

The following code forms the typical header for my Perl scripts:
It is possible to control the SSH client while being logged in to a server:
The SSH agent stores unencrypted private keys to help you log in to servers without supplying your private key’s passphrase during retries.
