How would I go about sending packets over the ethernet port on a Crestron processor (an MP2E)? I'm looking to do a bit of PC control / messaging, I can probably script what I want to do, but how do I get these packets onto the net? I'm thinking of writing a custom wake-on-lan module to go with this too (that gets it's mac address from a join, using a script that parses a text file stored in nvram that's already there for things like room name)

You either use a TCP/IP Client or Server (depending on how you want it to work) symbol OR if you're into your Simpl+ (this is how I would do it) you write a module that can open a direct socket connection to a specified IP address and port.

Check out the Simpl+ help file for more info on direct socket connections.

If you need more info post back I will post some screenshots of the relevant bits.

if your wanting to do wake on LAN its probably easyiest to use the SNMP part in simple although TBH i've never messed with it

you'll probably get a better response posting on the yahoo crestron programmers group

Pretty sure I can find the relevant symbol, but any more detail on implementation / how you would do it would be awesome. All my control at the PC end would be achieved using auto-it, with the exception of the wake on lan implementation. Currently the PCs come on automatically at 7.30 am and switch off automatically after 10pm (as long as there isn't a logged in user) - but people still switch them off, plus a couple of them have failed to come on in the past for whatever reason (duff bios I guess?)

I'm guessing that I don't need to bother going into scripting to send a simple message to an IP address / port in Simpl, but that the wake on lan part will require a little bit of code. It seems like we manage the PCs and the control systems independently at the moment, and that there's massive potential to combine the two, especially as it's the same people managing AV and IT - we also have some devices that aren't connected by serial, but that have PC based control software and USB ports, so it saves on extra Crestron hardware.

SeanT,

I've not forgotten about this thread just really tied up at the moment. When I get a bit of time I will get back to you...sorry for the delay.

[SeanT]

No problem, I've been waiting several weeks for some up to date original code for a couple of the rooms where I'm interested in doing this anyway - and can't implement major changes in term time either.

SeanT,

Have you managed to get this going yet? I'm not 100% sure that the TCP/IP client/server symbol is going to enable you to do this.

Forgive my ignorance, but when a computer with a WOL card is turned off, does it maintain it's IP address?
