MAC address

Hi,

Can I perform a test on a MAC address instead of IP address?
And if so, how?

Thanks!

Kris

Sorry, HostMonitor does not support such feature. As I know, not every router has MAC-ping feature enabled, so it is not a common way. Could you provide the reason you want to use MAC address instead of IP address?

Max

Hi Max,

We use about 100 thin clients that are on DHCP.
That's why I can't use the IP address to indentify the client.
Using the MAC address whould do the trick.

Thanks,
Kris

All systems in the same LAN? Then you may use hostname...

The TC's are indeed on the same LAN.
I'll give it a try!

Thanks.

Well,

It does work on the local network segment, but it doesn't for the TC's on our remote sites.

I guess that still requires testing on MAC address

I suggest you download snmpsend utility and configure it on all remote computers so that it will send the HM server an snmp trap let's say every 5 minutes, so you will know both the ip of the computer and whether it is alive or not.

But you will need to use port forwarding on your firewall so that all traps are sent to the HM server.

Plus, in order to distinguise each trap, you can add a comment for each computer, like comment:hostname. Only trouble is that you will only need to add as many traps to HM as the number of computers that you have.

IMHO MAC will not work with most remote networks...
However I have added your request into "to do" list. Medium priority

Sorry, we have more important tasks. This one will not be implemented very soon.

What happens if you ping a hostname?
As Ping packets use IP-protocol, the hostname has to be resolved either via DNS / WINS (if available) or by broadcast. The latter is only possible within your local subnet, because broadcasts are not routed

What happens if you ping a MAC-adress?
As Ping packets use IP-protocol, the MAC-adress has to be resolved via ARP. As ARP is a braodcast, this is only possible within your local subnet, because broadcasts are not routed.

=> If the IP-adress of your remote TCs cannot be resolved, it will be difficult to ping them (except you can configure your routers to route the broadcasts).

IMHO there are at least two solutions:
a) Fixed leases on your DHCP-server
b) RMA in the remote subnet
