And get this

I have been around the computer world using *nix long before freebsd came 
along. That does not mean what I say today deserves to be judged other than 
on its face value. However what over 40 years in IT has encouraged me to 
think  that those who invite people to judge a book by its cover have either

I am sure you have a lot of knowledge and experience but I doubt whether your 
collegiality is more attractive than your sense of humour. 
I recall you once said:
"remember sometimes my jokes are crude"
 judging by your contributions to this thread am I not entitled to wonder if

Now please take note;
1. This thread is entitled Limitation of Ports System. Please stay on topic.
2. If you want people to take you seriously either post some technical 
information relevant to the topic that gains you some credibility or press 
the delete key and keep quiet.
3. Please stop trolling.
4. You could start a thread "Why we should not discuss the limitations of Port 
System and keep your contributions on topic there. I can assure you that I 
will not be trying to highjack that dialogue.
