DHCP Usage

I don't think anybody reads this blog, but...

If anybody is reading (Hello? Is this thing on?) I have a question... How extensive is your use of DHCP? I'm slowly migrating almost every network device to statically assigned DHCP, including servers. Do you use DHCP for servers and other fixed devices?

Just wonderin'...

Upgrading RHEL from 5.3 to 5.4

I was having all sorts of strange problems while upgrading my test box from RHEL5.3 to RHEL5.4.  I did a search, but it didn't seem to turn up much... just a link to an unrelated problem, and a Russian website.  Well, I don't know Russian but I was able to decipher a hint: "yum clean all".  That did the trick.  I think I'll run that prior to upgrading all my production boxes.  Here's the error I was getting:

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
