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.

not quite... my ISP si a sdpd fck (sorry about the language). He told me that in order to resolve my host (for example the IRC) I had to wait some time in order for the host to propagate (????? don't ask me I don't know what it means) I told him to take a better look at his server.
I don't know what more to say... I guess he has to look in /etc/hosts or /etc/hosts.conf or at his named server (I'm not quite good at dns so tell me if I'm wrong).
To be more explicit:
My ip is 22.214.171.124
When I connect to an IRC server it gives me "Your forward and reverse DNS do not match, ignoring hostname. [126.96.36.199 != 188.8.131.52]"
My host is alex.tehnoprest.com and on irc it doesn't resolve.
The argument was very.... I guess I have to look for another ISP.
Wow, that's a lot of info, you might consider adjusting those numbers a bit to not show your actual IP if you haven't already.
What I think he was telling you is that there is a lag between the time when you add 'alex.tehnoprest.com' to your A record and the time it hits all the nameservers, especially your IRC servers nameservers. Usually (IIRC) I've never seen longer than an hour, however, it may vary.
This lag is very unlikely to take that long, however, if he/the company is in charge of your domain/host then it's possible a wait time they have (back logs and such). If you control your own zone, then once you add the info, I've never heard of a week. The most I remember hearing (and I believe this was in reference to something else) was 3 days.
thank you.... the interesting think is that yesterday the reverse worked fine... I didn't mess with my config. They say is my fault. I'm 100% sure that is theirs.
an off topic question:
1. 953/tcp open rndc
what's this what does it do how can I kill it
2. how can I change the time remotely from a console
3. if I enter an ip that is already asigned and that host is up is it possible that I "kick" that person out ? or I only get an Ip conflict message and that host continues working unbothered ?
thanks a million )
