Why would netdump give the error "netdump: cannot arp [ip address]" at the start the service?

Issue

• Why would netdump give the error "netdump: cannot arp [ip address]" at the start the service?

• When starting the netdump following error message is noticed:

  netdump: cannot arp <ip address>
  bash: line 1: /var/crash/magic/: Is a directory
  netdump: could not ssh to server <ip address>
  netdump server ssh key exchange                            [FAILED]
  

or

# service netdump restart
netdump: cannot arp ada on eth0
netdump: cannot find 10.31.101.80 in arp cache
netdump: can't resolve 10.31.101.80 MAC address netdump server address resolution [FAILED]

• How do I use eth1 as the netdump device in Red Hat Enterprise Linux 4

  root@XXXXX sysconfig]# service netdump start 
  netdump: cannot traceroute XXXX on interface eth0 
  eth0: error fetching interface information: Device not found 
  netdump: cannot arp XXXXX on eth0 
  eth0: error fetching interface information: Device not found
