SSL UUCP user shows up at boot

Hi Apple Gurus,

I recently tweaked my system to disallow certain services. I am quite fond of Linux and use on quite frequently Darwin and Terminal. I've setup Ports and have tried out Fink etc. I've even tried setting up Ubuntu on my Mac Mini (bought sometime around 2010).

Anyhow, here's my question. I've tweaked these services by adding the # sign in front of the services found in /etc/services as well as linked to /private/etc/services and now (perhaps 3 weeks later), I see reboot my system and see an extra user called Unix to Unix Copy Protocol. Why and how did this appear on my system?

I'm familiar with the UUCP but have never really used it, since it's legacy as I understand it. It's what was used during the ARPANET times and back when people were developing the Internet with Universities.

I also have another question. My root password has been comprised, and I can't even reboot the system in Single User mode to reset it. Can't Command/Option P-R or Command S. How can I reset my root password so I can reconfigure my /etc/services to disallow yet another UUCP service that I see has popped up, namely SUCCP (SSL UUCP). Wow I thought this UUCP stuff was unused nowadays. I guess I was wrong.

Any advice would be much appreciated.

Thanks

Michael
