Just some config documentation for DNS to get bind running quickly: http://everythingsolaris.org/articles/dfd/index.html#introduction

And a quick article on snoop, the equivalent of tcpdump - to be able to check what DNS is doing: http://www.softpanorama.org/Net/Network_security/Sniffers/snoop.shtml

Looks like bad DNS configurations can slow solaris down like crazy from what I am finding...

How to get more diag out of Solaris:

To set so machine won't auto-boot, at ok prompt:

ok >   setenv auto-boot? false

then >

ok >  reset-all

now, shouldn't auto-boot.

Back to running the diags, try:

ok > setenv diag-level max

and also:

ok>  setenv diag-switch? true

ok>   setenv diag-script normal

that's what I meant by the setting the 'diag' something type commands.

you can see all the variables with the :

ok>   printenv                 command.


then power off/on and see if more diagnostic code displayed which will help solve problem.
