 |
|
Does anyone have a clue about how to use the RPC Service Interface? I am trying to use it with VDS so that I can copy a client program (that will shut down a computer) and run it on the remote computer on the network... Seems that I am very close to finishing a script I have been working on all year if I can figure this out... but until then, I'm stuck... 
| Quote: | | This client is working on the system account and is not required to have additional user's threads or user's rights to shutdown or restart. |
Thanks for any help

Hi FreezingFire,
I think the only VDS DLL out there that could come close to doing this would be my Gadget DLL. If you have either some C/C++ or VB example code that uses RPC send it to me and I would be glad to try and translate it to my Gadget's syntax for you.

If you really are to use Gadget, try the InitiateSystemShutdown API call in advapi32.dll.
BOOL InitiateSystemShutdown(
LPTSTR lpMachineName, // address of name of computer to shut down
LPTSTR lpMessage, // address of message to display in dialog box
DWORD dwTimeout, // time to display dialog box
BOOL bForceAppsClosed, // force applications with unsaved changes flag
BOOL bRebootAfterShutdown // reboot flag
);
I really doubt this allows the remote machine to be powered off though. |

Tommy,
According to the Win32 API help file that I posted to vdsworld.com's Doc's section it says
| Quote: | To shut down the local computer, the calling process must have the SE_SHUTDOWN_NAME privilege. To shut down a remote computer, the calling process must have the SE_REMOTE_SHUTDOWN_NAME privilege on the remote computer. By default, users can enable the SE_SHUTDOWN_NAME privilege on the computer they are logged onto, and administrators can enable the SE_REMOTE_SHUTDOWN_NAME privilege on remote computers.
Common failures include an invalid or inaccessible computer name or insufficient privilege. |
I am thinking of looking into SNMP and see if there is some simple examples that I can put together either with Gadget or with another DLL.
As for using RPC I will need to do some research on using this before I could say if it can be done or not.
I might add remotely shutting down PC's is not a good thing and if used in a bad way it could be very dangerous  . Security has to be accounted for here and any programs written should not be released to the general public.

Just my opinion here... Remotely shutting down PC's is not a good thing if used in a bad way. Yes it could be very dangerous if used in a bad way. Security does need to be accounted for. But I disagree that because a tool has the potential to be used in a bad way that it should not be released to the general public. Where would we be if all the tools that had the potential to be used in a bad way were never shared by their inventors for fear that someone might use it for something other than the intended purpose? |

I must agree with it that this is absolute nonsense. All things can be used to do bad things,
even a pen could possibly be used by someone out there to kill someone. |

Hi All,
The only thing I really have to say here is that locks are only there to keep an honest man honest.
I don't know about you but I would not be very happy if while working on my gadget DLL someone targeted my PC and shut it down and I loose everthing that I was working on. While I do have backups and I have taken steps to lessen the effects of something like this happening no system is 100% and until that happens I do not think that we should write software that can be destructive without taking the proper steps to control such power. That was all I was trying to say.
Also would you give the blueprints of where you hide your valuables in your house to a thef? I would not... Just food for thought...

A firewall such as ZA (Zone Alarm) should stop
unauthorized access to your PC, both from the
internet and/or a LAN...
Cheers, Mac

Also of course you could simply disable "Client for Microsoft Networks" on your internet-specific
connection. |

This program is intended for the administrators of a school's network. They then can remotely shut down a computer. So far, I have found no other way to power off a remote computer. There are plenty of programs out there that use the RPC Service Interface, including ones to shut computers down with. The program is not intended for bad use.
If anyone else knows about any ways to power off a remote computer on a network without using the RPC Service Interface, I'd like to hear it.

I think this will work for shutting down remote computers if you have Gadget:
| Code: |
external gadget.dll
%%STDCALL = 32
%%STDCALL_MS = @Sum(%%STDCALL,%%Microsoft)
%%advapidll = @Gadget(demo,loadlib,advapi32.dll)
if %%advapidll
gadget demo,declare,InitiateSystemShutdown,%%advapidll,InitiateSystemShutdown,lpMachineName As String;lpMessage As String;dwTimeout As DWORD;bForceAppsClosed As Long;bRebootAfterShutdown As Long,Long,%%STDCALL_MS
info @gadget(demo,InitiateSystemShutdown,backup,System is about to shutdown...,60,0,0)@cr()
gadget demo,freelib,%%advapidll
end
|
I don't think this will actually power off the computer though, I think it would leave the
"You can now safely power off your computer" message until manual reboot or poweroff. |

The ideal way to do it is (and I've seen it in action) to copy the client onto the network computer and run it (RPC Interface), and using VDSDLL shut it down. It seems simple enough, but is really hard to find out how to use RPC Interface.

I think using the utility I posted a link to, it won't even be neccesary to copy any tool
to the remote computer, I think the tool can power off the computer remotely on
its own. |

That article looks like it may a big help! Thanks, Tommy! 
I just have to look into that, but I don't know if that alone will lead me to an answer...
