Portsentry logs the connection attempts to a special file called portsentry.history. This file is located in /usr/local/psionic/portsentry directory by default. Mandrake comes with it pre-installed and is located at /etc/portsentry directory, instead. You will need to bee root to access the default directory. I like the separate logging as it is easier to see exactly what you are looking for. Good luck.
Happy Hacking
