Finding a Mac Addy on our HPUX over a network. ??

[someone_4]

Is there a script or command that can find a mac address over our network? I need to find a certain mac addy and know what hostname it sits on without having to telnet in everybox. And looking at each nic one by one. All of our boxes are trusted so I can do a remsh to all of them. Any one have any ideas?

Thanks

Richard

Hi Richard
lanadmin -a 4 (4 = NetMgmtID)
Put this in to the script.

foreach system(SYSTEMS)
remsh system -n lanadmin -a 4
end

Hi Richard,

One method is to simply arp -a.

You could also remsh to each machine and do an arp -a and capture that output.

What you really need is a reverse arp utility.

Hi Richard


Do a man arp and you will get the options .

for your local server
lanscan is the best
For network elements other hosts, printers ....
arp

Hi Richerd,

Your script is the following :

#Create a file including all your servers names one per line in /tmp/serversNames for example.

mac= // replace the name with your mac address
serversNames=`cat /tmp/serversNames`

for currentServer in $serversNames
do
currentMac=`remsh $currentServer -l root -n "/usr/sbin/lanscan" ? grep $mac`

if [[ $currentMac != "" ]]
then
lan=`awk '{print $5}'`
ip=`remsh $currentServer -l root "/usr/sbin/ifconfig $lan" ? awk '{print $2}' ? grep -v "flags"`
echo "### Mac address : '$mac' is on server '$currentServer' for ip address '$ip'. "

exit 0
fi
done

echo " !!! this mac $mac is not belonging to these servers $serversNames. "

Good luck.
