Wake On LAN

[jarednichols]

Is there any mechanism that folks know of to do wake on lan in Casper? I can't seem to find anything in the documentation. Or, do folks leave this up to ARD?

Thanks!

I don't recall anything specifically in the Casper tools, however, if you
define a maintenance window, you could use a pmset script to ensure
computers are on and awake at a certain time.

Hello,

This is a feature request - but I was looking for a way to do this today.

It would be nice if Casper Remote would automatically do a Wake-on-LAN if it fails to initially get an SSH connection - that way the computer would be awake when it retries SSH.

Just a thought.

I agree that this would be a good feature. This is fairly limited though for large networks because, normally, WOL packets get limited to the local subnet, at least in our environment. Do other people have this issue?

That would be our limitation as well Ryan. We would need to have a system on that segment that stays awake to send the packet. On the Windows side here that can be accomplished with Night Watchmen, which is what we use for power management for Windows. To the point that if the one system in that subnet goes down it's smart enough to wake one up before it goes down first so one system is always there under normal circumstances. We were going to look at a way to feed the information about the Macs network connectivity to it's database so it could send the packet as well, but the JSS doesn't collect enough of the network information we need to do it from initial conversation.

It would be a very helpful tool to have right in the JSS.

This would probably be more work on JAMFs part - but when I was testing out OCS Inventory NG, it had a great feature where it would use a client in a different subnet to issue commands that are limited by subnet.

For example:

JSS is in Subnet A
Client 1 is in Subnet B
Client 2 is in Subnet B

When Casper Remote could not SSH in the client 1 and couldnt do a Wake-on-lan because it was in subnet B -- Casper Remote would find a different client (2) in Subnet B that it could SSH into and have client 2 do a Wake-on-lan to Client 1.

Obviously it would be some work on JSSs/Casper Remotes part to find Client 2, but it could probably base that on Network Segment and last check-in time.
