Remote desktop

Inazuma · 30 Dec 2009 at 18:23

Hey everyone,

I want to set up remote desktop between my PC and my laptop (both use Windows 7). I want to be able to access my PC using my laptop from my flat (including turning it on remotely). The PC uses a Thompson Speedtouch router and the flat has a talktalk router (not sure what model).

Can you give me information of how to set this up? Including settings that need to be changed in the BIOS and router.

Happy new year

LogMeIn allows you to turn on a remote computer. You will need to turn on "Wake On LAN" or something similar in the bios.

I've found "Wake On LAN" to be very unreliable over the internet. I read that the wake-up data packets are often dropped by routers on the way.

Is is called "Wake On LAN" and not "Wake On WAN" after all.

And what software do I need to actually achieve remote desktop?

Ensure WOL capabilities are enabled. On my comp these are:
NIC Properties -> Configure -> Advanced -> "Shutdown Wake-On-Lan" and "Wake on Magic Packet"

Set the PC up with a static IP:
NIC Properties -> "Internet Protocol Version 4" -> Properties -> "Use the following IP address:"

Enable the telnet client in Windows 7:
Control Panel -> Programs -> Turn Windows features on or off

...or use something like PuTTY

Router setup:
Backup your Speedtouch config via the GUI. Also via the GUI, go through Toolbox -> Game & Application Sharing to create and assign a new entry to the PC for UDP forwarding, port range 7-7.

Test:
You should be able to wake the PC up from S3 sleep using this page, http://www.depicus.com/wake-on-lan/woli.aspx but only for a few minutes after you put the machine into standby.

Router config:
Telnet into the router and enter the commands:

ip arpadd intf=LocalNetwork ip={PC's IP address} hwaddr={PC's MAC address}
ip arplist - to confirm.

Notes:
1) The arpadd command might have to be issued using a computer with a different MAC address. This could be accomplished by temporarily configuring a "soft" MAC address via:

NIC Properties -> Configure -> Advanced -> "Network Address" field

Returning the option to "Not Present" when completed.

2) You may first have to delete the dynamic ARP entry by issuing:

ip arpdelete intf=LocalNetwork ip={PC's IP address} hwaddr={PC's MAC address}

if there is an existing line prior to "faking" the MAC address.

3) Increasing the telnet session timeout reduces frustration:

env set var=SESSIONTIMEOUT value=600 - in seconds, 0 to disable.
env get var=SESSIONTIMEOUT - to confirm.

Might work. I've not got two comps to check
