Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi there, wonder if someone can help me out. Think my cable modem is blocking http request coming from the web. I have a linux box doing masquerading and I'm able to access my server internally using my public IP. However, if i try accessing the site outside the network, I get a site not responding error.
My cable modem is a Motorola SB5100, when i access the configuration page of the modem. I don't see any option to block http traffic. The modem came from my ISP (Adelphia). Do you think if i replace the modem that would solve the problem?
Also i constantly getting this request. Could this by my ISP testing if i have a http server running???
I am having the same problem. I'm running an SB4100 with Adelphia. I bought my modem at Best Buy 2 years ago so I don't think Adelphia has done anything to your modem. I am running Suse 9.2 and have everything set up the same as a friend of mine on his system that works (he has Time warner is the only difference). I can access my linux website internally (XP) thru my external name just fine. When I try to access my site from outside my network using a work pc or friend's pc it just times out. I can't do http or ftp externally. I'm in the same sinking boat. I have tried everything, read forums and books. I even had friends take a look, no luck. Know your pain.
A friend of mine, networking pro, has Adelphia in So. Calif. For many years they have blocked HTTP and similar ports to discourage web servers. I presume they port-block in their routers not the cable modem.
He has always used high port numbers for his web servers - and has found some free or nearly so redirectors on the internet -to redirect a domain and http port 80 address to his address and high port numbers (i.e., make it transparent to others). As I recall, they have high tier ($$$$) service which does not port-block.
I have Time Warner/RoadRunner which has not blocked ports - instead the supposedly monitor and challenge bandwith hogs.
