Pump

pump is a program that acts a bit like dhcpcd or dhclient.

pump is a daemon that manages network interfaces that are controlled by either the DHCP or BOOTP protocol. In simple words, it asks the DHCP (usually: router) for an IP address.

Usage:

      pump [-krRsd]   
           [-c|--config-file FILE]   
           [-h|--hostname HOSTNAME]
           [-i|--interface IFACE]   
           [-l|--lease HOURS]    
           [-?|--help] 
           [--lookup-hostname]
           [--no-dns]  
           [--no-gateway]  
           [--no-setup]  
           [--no-resolvconf] 
           [--release]
           [--renew] 
           [--script= ISCRIPT]
