    umm.. I think if we view the original post, it shows in his example "C:\ping."
    By just taking a wild guess I feel that were dealing w/ a windows related machine (booo!!) =(. In that case, there is no given command of "rarp."

    So think he should re word his post to, "how do I use rarp in windows?"

    I googled different things, and couldn’t really find it either. I checked the various ARP switches in MS-Dos, and i didn’t find anything that would translate hardware address to a Logical Address.

    But the thing is i don’t see the sense dealing w/ rarp when working with workstations. (Maybe some of you can enlighten me)

    Just wanted to make all aware. =)

    Thank you.

    <HW>=Use '-H <hw>' to specify hardware address type. Default: ether
    List of possible hardware types (which support ARP):
    strip (Metricom Starmode IP) ether (Ethernet) tr (16/4 Mbps Token Ring)
    tr (16/4 Mbps Token Ring (New)) ax25 (AMPR AX.25) netrom (AMPR NET/ROM)
    arcnet (ARCnet) dlci (Frame Relay DLCI) irda (IrLAP)
    x25 (generic X.25)
    This command can't be used to find that IP address that is being used by a given MAC address.

    A utility called arping can be used to accomplish that.

    hactar:~# arping 00:00:0C:92:A1:55
    ARPING 00:00:0C:92:A1:55
    60 bytes from 192.168.1.1 (00:00:0c:92:a1:55): icmp_seq=0 time=2.385 msec

    I'm using the version available from http://www.habets.pp.se/synscan/prog...hp?prog=arping.

    Service or command?

    IIRC, the phrase is "We could tell you, but then we'd have to kill you"

    started a topic ARP and RARP?

    ARP and RARP?

    These days i am reading the book <<TCP/IP Illustrated volume 1:Protocols>>,written by W.Rechard.Steven.It is really a wonderful book for me a beginner.And i have a question here:
    There are two hosts on an Ethernet:A(192.168.0.1) and B(192.168.0.2).Now i am operating on the host A.Now i want to get the MAC Address of B,so i type the command:
    c:\ping 192.168.0.2
    then
    c:\arp -a
    And in the arp cache i get the MAC Address.
    The question is if i have the MAC Address of B,how can i get its current IP Address?I know there is a RARP,how can i do it ?
    thanx.
Working...
