Description of Problem: I use two configurations with eth0 interface of my laptop, one with fixed IP and another with DHCPD (when I'm roaming). The configurations are /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth0.dhcp. When changing back to configuration with fixed IP address (ifup eth0) from DHCP configuration (ifup eth0.dhcp), the pump daemon is left running and the IP address the pump ackquired is still assigned to the interface. In random intervals, pump overwrites the /etc/resolv.conf and when its lease expires, it removes the fixed IP address. Version-Release number of selected component (if applicable): initscripts-6.40-1 How Reproducible: Always. Steps to Reproduce: 1. On a host having fixed IP address on eth0, create alternative configuration using pump, e.g., cat > /etc/sysconfig/network-scripts/ifcfg-eth0.dhcp << EOF DEVICE=eth0 USERCTL=yes ONBOOT=no BOOTPROTO=dhcp EOF 2. Install pump (and uninstall dhcpcd): rpm -i pump-0.8.11-7* ; rpm -e dhcpcd 3. Activate dhcp configuration: ifup eth0.dhcp 4. Reactivate fixed IP configuration: ifup eth0 Actual Results: At step 4, adding default route causes a complaint as the route from DHCP still exists. Both IP addresses, one from DHCP and the fixed IP address, are active Pump is still running. $ ip addr show dev eth0 $ pidof pump Expected Results: Address from DHCP is released and pump is killed.
