ftpUP was designed as a more reliable and quicker acting alternative to dyndns for making Web servers, which are connected via dial-up links, available under a fixed address. It gets your IP on a definable interface and creates an html document containing the current URL of your local server, and uploads it to an existing website. You can also include a logo or other information in the file which is uploaded. Another advantage over dyndns is that the link can point to any URL, ie. your websites can be delivered from anywhere else if your local server goes offline.
shwatchr is a small Perl script that audits logins to shell accounts on Linux/*NIX machines that originate from arbitrary hosts on the Internet. When a successful login occurs and a shell is spawned, shwatchr is executed from the shell rc file and compares the host from which the login originates against a list of known/allowed hosts. If a match is not found then shwatchr can be configured to either send an email to a separate alert email address that contains the time and host from which the login took place or issue a warning and proceed to kill all user shells. shwatchr does not require root to execute and hence users can have some measure of knowledge and security over who is logging into their accounts even if they can't modify firewall or tcpwrapper rulesets, or look at system logs.
