dhcpd on redhat 6.1 sparc is broken.
ftp the older version from 6.0 release, force install over the 6.1 dhcpd,
it works fine.
I believe the dhcp client is also broken?
Using pump (also packaged with RH 6.1) works fine on my SPARC machines for
the DHCP client... but yes, I had to use the server from 6.0 on my SS5/70
that does my DHCP serving...
This will be fixed in the next release.
