If you have visited us before, you will have noticed a big change.  After a decade of being on line, we have made the site a bit more dynamic.  With no bells and whistles, we are far from being "cool".  But hopefully, we are more useful than before.

We started off in 1996 as a father & son team and leased what was then a "super fast" 128Kbits ADSL (copper) line with a handful of fixed (static) global IP addresses.  Unlike the broadband lines with one dynamic IP address available to most consumers, the multiple fixed IP address line allowed us to learn the ropes of the Internet with hands-on server experience.   Those were the days before the "Dynamic DNS" technology came into being which allowed connecting a server to a dynamic IP address and still be accessed by the Internet community.

Yes, we could learn from technical  books, from on-line documentation, the open-source community, newsgroups, forums and more recently from blogs.  We also learned from the corporate internet/intranet environments that we integrated and maintained. But much of what we know come from putting them into practice (even if temporary) using our own (now 100Mb fiber optic) Internet pipe with fixed (static) global IP addresses.  

Unlike corporate environments with the strict rule of "Don't fix it if it ain't broke", our environment allows us to "fix" and inadvertently break our own servers or watch outsiders break them.  We are free to tweak and experiment and do not have any sense of panic when things go wrong.

From honey pot clients and servers, to production web, email, DNS, FTP servers, and the like, we learned and continue to learn.   And yes... we continue to have our own share of headaches, such as spam, DDoS such as Syn Flood, vanilla DoS, XSS, content vandalism, bandwidth theft, viruses, trojans, spyware, or just plain brute force break-ins.   We strive to learn from these real-world problems.

That's what makes computing truly interesting... it is an endless learning experience.

Because we continue to learn from the Internet community, we share here some of our two-cents worth of experience.   They are trivial to be sure, but for those who are in urgent need of these solutions, we hope our humble efforts help somewhat.

We sincerely thank you, the Internet community, for this stimulating experience.
