<DIV><FONT face=Arial size=2>Hi everyone.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This might not be the correct place for this, but
here it goes.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have made a little program using winpcap to send
rarp packets,</FONT></DIV>
<DIV><FONT face=Arial size=2>to find out the ip address of a specific mac
address.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When i have assembled my rarp packet i send it via
winpcap.</FONT></DIV>
<DIV><FONT face=Arial size=2>I am using ethereal to check if my packets are
correctly put together,</FONT></DIV>
<DIV><FONT face=Arial size=2>and according to ethereal, they is. The
packets that i send can nicely be</FONT></DIV>
<DIV><FONT face=Arial size=2>seen in ethereals window, with the correct
addresses and opcodes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now, the problem is that i never get a
reply.</FONT></DIV>
<DIV><FONT face=Arial size=2>According to rfc 903 rarp is mostly used for
diskless systems to find</FONT></DIV>
<DIV><FONT face=Arial size=2>out their ip when they boot.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>I have tried any combination of arp/rarp type
(0x0806 and 0x8035) and</FONT></DIV>
<DIV><FONT face=Arial size=2>any of the opcodes (1..4).</FONT></DIV>
<DIV> </DIV>
<DIV>Now, the question remains, are normal workstations/servers not
supposed</FONT></DIV>
<DIV><FONT face=Arial size=2>to answer rarp packets? I have a mixed environtment
with 50++ computers,</FONT></DIV>
<DIV><FONT face=Arial size=2>windows workstations, windows servers and linux
servers...</FONT></DIV>
<DIV><FONT face=Arial size=2>None of these answer my rarp packets.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Hopefully someone can shed some light on
this.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks.</FONT></DIV>
