Double Copies Double Copies

Hey Y'all, why am I getting double copies of every email on this list 
today when it wasn't happening yesterday?  Isn't happening on any of my 
other email.

How does a linux DHCP machine inform DNS of its name and obtained address

I am using a number of DHCP devices on a network. Working fine with 
CentOS  5 x86_64.
My question is now how do I tell the DNS (after I get my DHCP address) 
about my devices
name and IP address so that others can find me by my machine name?

I thought that was an automatic thing - but it appears not.

Thanks,

Jerry

I wrote this years ago, so it might need updating, but the basics should
still be the same.

What you want is called "Dynamic DNS" (or DDNS for short), and it needs to be 
active on the DNS server, if it is to work. You cannot make that work only by 
configuring the client.

It is not automatic by default because in principle it can represent a 
security vulnerability, if not used properly.

HTH, :-)

Yes another "I can't open port 53 for Bind DNS"

Hi,
          It's just past 3am and for the past 6 hours I've been 
configuring a secondary name server to replace one that just crashed.  
My problem appears to be that port 53 is not open for some reason on my 
server even though I have this:

[root <at> tribe etc]# netstat -an | grep ":53 "
tcp        0      0 205.211.154.3:53            
0.0.0.0:*                   LISTEN
tcp        0      0 127.0.0.1:53                
0.0.0.0:*                   LISTEN
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*
udp        0      0 205.211.154.3:53            0.0.0.0:*
udp        0      0 127.0.0.1:53                0.0.0.0:*

But with a test from
http://www.yougetsignal.com/tools/open-ports/
it says port 53 is closed.

I'm using CentOS 6.0 and BIND 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2

Obviously those commands are all on one line

so the  '--state' is followed by 'NEW,' and not line wrapped as in this 
e-mail

I think you will find this a good resource:

I still get only one mail, as it should be.

Maybe your server-client connection is getting berserk. do you have 
webmail access so you can check if duplicate mails are on the server also?
