"Then I decided to check out the newsgroups to find some more information to get things running how I wanted them. I don't recall which newsgroup it was, but I got a huge shock when I found out how insecure my box could be now that I had the ability to run all these funky services that I thought were run only by servers. Could sendmail really be running? Why? Is some unknown person trying an exploit on my ftp port? Run 'netstat -a' I was told by an anonymous usenet poster. Lo and behold, I had not just one or two services actively "listening" for connections, but many."

"Why would a home user need any of these services running? The way I see it, there are too many home users trying Linux nowadays for most every possible service to be running on a stock install. If any of these users are like myself, they install everything just so they can see what is available. Then not only do they have to go through and shut down unnecessary services like sendmail, ftp, portmap, yp, etc, but they have to learn how to do this first. Linux is mainly a server OS, and has been for years. Most administrators know what any given box is going to be doing before it's even installed. It makes sense to me that administrators would to have to turn any given service on, rather than turning off what they don't want. That directly relates to home users as well. Especially the new ones just now trying Linux with their cable or ADSL modem connected 24/7."
