pump doesn't retrieve DNS server ip address - no /etc/resolve.conf is generated. As a consequence, a linux box using DHCP protocol could not lookup internet address by hostname. However, dhcpcd, which pump is supposed to replace, generates /etc/resolve.conf automatically. pump (or any startup scripts that use pump) should be modified to do the same.
This used to be a problem with earlier versions of the pump packages as orginally shipped with 6.0. It has been fixed in the latest release. Please download and install the latest pump rpm ftp://ftp.redhat.com/redhat/updates/6.0/i386/pump-0.7.0-1.i386.rpm Please reopen this report if the problem continues.
