I have bind installed and default config running.  I have not applied my
customizations yet.  The first step I am taking is getting rndc.key
created.  So reading the guide I am trying to run (while logged in as
root, and in /etc):

dnssec-keygen -a hmac-md5 -b 256 -n HOST rndc.key

The system is just sitting there and doing nothing.  I have sshed as
another session and do not see any processing being done by dnssec-keygen.

Has anyone else done this?  Am I doing things in the right order? If it
works for others, then there is something wrong with my setup...

It's working fine for me.

I'm using the command ldns-keygen to generate keys though - e.g.

ZSK=`/usr/bin/ldns-keygen -a RSASHA1-NSEC3-SHA1 -b 1024 ${zone}`

and

KSK=`/usr/bin/ldns-keygen -k -a RSASHA1-NSEC3-SHA1 -b 2048 ${zone}`

ldns-keygen is from the ldns package.

Mine is currently all scripted and automated, has been for months - I started with an Ubuntu tutorial though, not CentOS documentation, and adapted it.

I'll have to look at the scripts I wrote more carefully when I get home (wonder if I should be using different than SHA1 now too? I'll have to research that)

Right now all I want working is rndc.  dnssec will be worked on come spring.

With all I do in security, it bothers me that the Centos documentation specifies MD5. Should be at least SHA1, if not SHA256.
