I'm running the BIND9 on AIX 5.3. My OS does have /dev/random and /dev/urandom.
# odmget CuDvDr | grep -p random
CuDvDr:
resource = "ddins"
value1 = "random"
value2 = "34"
value3 = ""
crw-r--r-- 1 root system 34, 0 Feb 26 2009 random
crw-r--r-- 1 root system 34, 1 Feb 26 2009 urandom
I'm running BIND9 on 4 DNS servers with same build, same OS. 2 of DNS servers
are running with no problem. The other 2 show error in the dnssec log:
13-Apr-2010 15:17:17.122 dnssec: debug 3: validating @202be918:

(keyid=47948): You must use the keyboard to create entropy, since
your system is lacking
/dev/random (or equivalent)

Did you build BIND yourself? When BIND starts does it log anything
like: "--with-randomdev=<something>"?
What operating system, etc? You haven't really provided very much
useful information in your question...
DNSSEC needs entropy for signing -- it believes that your system does
not provide a useful source of entropy (do you have a /dev/random?)
and so it want you to add some. This is not a BIND problem, it is an
OS (or more likely configuration issue).
