Below is a solution to the ifconfig problem: command not found. There may be times when network tools are not installed, i.e.. ifconfig, arp, netstat, rarp or route:

    -bash: ifconfig: command not found
    -bash: arp: command not found
    -bash: netstat: command not found
    -bash: rarp: command not found
    -bash: route: command not found
