WOL across Subnets ?

[marcS]

hi, we have 3 Networks with RR_Clients.

192.168.0.0/24 192.168.1.0/24 192.168.50.0/24
RR_Server is in 192.168.0.0/24 and can ping all Clients.
This is done via Routing, the other Networks are not physicaly connected to RR_Server.
arp -a will not list the MAC Adresses here.

- RR_Clients in 192.168.0.0/24 will do the WOL thing as expected. same Network
- RR_Clients in both other Networks will not wake through RR_Control -> Machine -> WOL
- If we send a WOL Paket via ether-wake from inside the Networks RR_clients will wake up.

I know WOL Packets are send to BCast,
- do we have to find a way to route the BCast Packets to udp 2304
from 192.168.0.0/24 to 192.168.1.0/24 and 192.168.50.0/24?

OR whats about this clue?
-We also have a RR_Server in 192.168.1.0/24 which is linked (relink_win.cfg) to the RR_Server
in 192.168.0.0/24 so i tought the "send WOL-info" will be created on the RR_Server in 192.168.0.0/24,
see that the targed Network is 192.168.1.0/24 send the WOL infos to the linked Server in
192.168.1.0/24 and send the WOL packet from the linked RR_server in 192.168.1.0/24 to clients in his
Network.

- whats about a pre-renderscript which will run in each network to send WOL Packets?

which direction you suggest ?

Hi

You can only run one server for a bunch of clients, so if you have a server in the other network, then you have to split clients and jobs.

Afaik it should work that WOL packets are send between different networks if the IP and the MAC address is set right in the client config. You can also specify the WOL post in rrConfig, tab clients global.
You also have to set the subnet mask right on that page.
One issue: if you use different subnet masks, then it could not work to WOL all clients in all networks.

Due we cant route directed broadcast pakets...

whats about a PRE script to wake RenderNodes across Subnets?
would like to create a PRE witch runs a windows cmdline.
i can use psexec inside to execute batch files on other hosts via cmdline. will have one online in each subnet to wake all other hosts in subnet.
what i need for is a variable or similar within hostnames oder ip's the job will be submitted for.

plan:
farm is offline accoss all subnets
submitter starts - my pre script is always selected.
operator select a pool of nodes (does not matter offline or online clients)
he submits the job to some nodes
pre script will wake up the list of selected nodes.
but any change to get a IP / hostname list as parameter for my pre script ?

or is there a way to edit the targed IP where RR sends the WOL Paket ? it should not be on 192.168.1.255

[schoenberger]

No, there is no way to get the list of all assigned clients in a prescript.
For now, I do not have any solution.
Perhaps if you could connect the rrServer with 3 network adapters to all subnets.

You have the setting in the client config for the IP range. (client menu or rrConfig tab "clients")
Then you have the addtional WOL settings in rrConfig tab "clients global" (perhaps you have to check "advanced" )
