How to know an oscilloscope's MAC address?

[[email protected]]

HI,All

I have an oscilloscope in hands and I want to let it access to the
internet then I can "see and operate" it from distance (in an intranet
actually).BUT-this oscilloscope could obtain a dynamic IP address,
which is private IP address. This is the first step, next I must tell
this IP and MAC to the administrator to get a new IP address.
Here is the problem:
I must know the MAC or physical address because in my area the network
administrator only assigns IP address combined with MAC address.

How can I solve it?

Buy the way , it's a Tektronix one with E-scope function.

Thanks.

1) Look it up on the sticker.

If it has been removed:

2) Install (free) ethereal, connect scope to PC with a single switch, hub or
crosscable, start ethereal, turnon scope. I expect the scope to send out at
least one packet, which will show the MAC address (and possibly it's current
IP address.

Just in case it runs a windows user interface :

run "ipconfig /all" from the command prompt.

1) Your admin can find this information by looking at the current IP
assignment in his DHCP server; the MAC address will be listed there.
This is likely the same system where he will assign your IP address.

2) Your admin can look at the router's ARP table for the current IP
address.

3) You can ping the device from your PC and then issue the command 'arp
-a' on your PC (this must be done from the same IP subnet / block to get
the right MAC address).

The Address Resolution Protoocol (ARP) daemon keeps a cached mapping
of IP addresses to MAC address for all interfaces attached to the
computer on which the daemon runs. Got to a computer that has an
interface directly connected to the interface of the Tek, then at DOS
prompt:

arp -a

This will dump the cache for all interfaces in tabular form.

arp -?

This shows usage of ARP command.

Do you have the ability to set the settings on the scope? Just set it
for DHCP, and tell the sys admin that you have a DHCP device you're
plugging in. His DHCP daemon will assign an IP address, and retrieve
the MAC address, so he can run his script and update his configs. ;-)

Have Fun!

thank you all. solved.

Some admins 'lock down' their DHCP servers so they only issue IPs to
known MAC addresses.

Then, if he doesn't know, he'll have to check the unit's docs, and work
with the admin in either case - you never know - he might not bite.
