for starters "portmap-4.0-17.i386" is for the very ancient RH6 ( from the year 1999)
and not the current RHEL 6.3
Red Hat chanced it's naming back in `03
the very OLD RH6 is not the same as the current RHEL 6
it will never install on a modern OS
try this
Code:
su -
rpm -e portmap-4.0-17
----------- or ----------
yum remove portmap-4.0-17
what exactly are you trying to do ?
there is a RHEL 5 version but red hat changed a lot of things in RHEL6
rpcbind or NFS might likely be what you need to configure
