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 213.233.122.108
When I connect to an IRC server it gives me "Your forward and reverse DNS do not match, ignoring hostname. [213.233.122.98 != 213.233.122.108]"
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.
Anyway...
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.
WRT DNS:
There are like 12 (or 24?) main backbone DNS "authorative" servers. These are all over the world. It takes a while for your new 'host' to arrive in their servers. This is the lag mentioned
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 )
