Linux_logo is a program, that can be used to pretty up your open ports, like telnet, ftp, ssh etc. It outputs text in ansi or ascii (depending on what you want). Currently it is in the version 5.03, that was released on 3rd January 2008. It provides system information, along with pretty ansi graphics of tux or debian, or something custom (if you want). It can be displayed in the login screen as well (the text based ones, and not the xserver ones). It is again distributed under the GNU GPL.
