Hi, a naive question, why do people open high port numbers on firewall?
|
|
|
|
|
Maybe because they need them open for return traffic from things that run on protocols like RPC.

Online games sometimes use high ports, coduo mostly uses port 28960...

Hi, I have a question relating to wireless router. I have dlink wireless router[^] 5 port (1 port for WAN and 4 port for LAN) and built in atena for support wireless router. My question is: I just want to turn on the router but turn off the wireless signal. Is it possible to do that? Because sometime i want to allow it run both or run only router port but disable wireless connection.

depends on the feature set of the router. My Netgear allows me to disable the wireless interface completely and just use it as a router.
If you can't disable yours can you remove the antenna? Some models allow you to unscrew the antenna.

Thank you very much for your information. I will check my router feature again and i found that the atena also could be remove. Does it affect the quality of the router if i remove the atena? Because i did not found any feature that allow me to remove the atena.

The antenna has no effect on the ability of the router to route packets. Removing the antenna will just cripple the usable range on the wireless transceiver, but not disable it completely.

Thank you very much for your comment. So how could we completely disable the wireless networking?
|
|

If your router doesn't supply some kind of settings in its management UI, you can't.
I've got a DLink 774. You can't turn off the wireless trans on it either.

wrapping it in tinfoil would further degrade reception, although there would still be leakage where your ethernet cables came out.
If you're willing to void the warantee, and risk breaking the router to permanantly disable wireless, you could try opening it up, and severing all the circuitboard traces coming out of where the antenna was connected.

 IF I wanted to disable my wireless, I'd consider it!

Hi, does anyone have a problem while using USB mouse with a laptop? I have a problem with my new laptop. If i use the touch pad to move the mouse and click it is fine. But when i connect the new USB mouse to the system, the mouse pointer seem to move slow from it orginal location while i did not touch the mouse or mouse pad. It really make me annoy with this mouse so much because i did not feel comfortable while using my PC. Does any one have any solution to fix it?
|
|
|
|
|
Try this:
Control Panel->Mouse->Pointer Options->Motion
|
|
|
|
|
Thank you very much for your comment. I just try to install new USB mouse and found it seem working very well. I will try this night and let you know the result.
|
|
|
|

I already test this option last and finally i could found the result. Whether i change the motion option with the mouse, but it still have a problem. The mouse still move itself while i did not touch it. But when i try to change the new mouse it is working fine and very comfortable for me. So i can say that, the problem came from the quality of the mouse. I'm gonna to change it soon.
Thank you very much for your big support

Hi,
I've also seen this happen many times with a notebook having both touchpad and USB Mouse. Usually, the trick is to deactivate the onboard touchpad. The PC gets confused with the X/Y coordinates information coming from two active pointing devices at the same time. I have seen the cursor begin to wander on its own without touching anything! Deactivating the touchpad solved my problem immediately.

Thank you very much for your comment. I already deactivate the touch pad but the problem still remain. As i reply in the previous thread, the problem came from the quality of the mouse. When i try to attach the problem with other PC it also have this kind of problem. And when i change the new mouse for my laptop the new mouse working fine wether i de/activate the touch pad.

Hi, i have a file in windows explorer of windows xp pro. I want to prevent the user to copy the file out of this computer. which method below that is appropriate to use:
- Turn of copy command in windows explorer menu or right click menu. Is it possible to do that in regedit?
- Hide all removeable media such drive A:, flash drive, CDRW, bluetooth...
- Turn of the Save As command in relate document editor.
- Turn off short cut key Ctrl + C in windows explorer.
- Encrypt the file (using windows encryption system or other external tool such as http://www.codeproject.com/dotnet/EncryptFile.asp[^]). But the owner could decrypt it back... I want admin to encrypt it but user just use it as normal but could not copy it to outside.
- Using Information Right Management?
If anyone of you used to challenge this kind of problem please let me know which solution that is good for me to choose.

That is pretty easy for WinXP pro.
Select Start->Run. Type "gpedit.msc" without qoutes and press ok.
then search under administration templates for setting. Then i suggest that you make sure that account is limited. If a user knows how to correct this setting, with admin rights he can return to previus setting

Thank you for your comment. I already check an option as your comment and found some option that could offer to my need but not completely. One of option that i found that is usefull is prevent the user to burn the file to CD. And around two or three more option are pretty good too. It is a little bit difficult stage while I allow the user to access while but try to prevent them from distribute the file out of my PC.

Thank you very much for your comment. I also concern about this issue too. I think the best option might be the Information Right Management. Because an introduction page give me an information that I search for. But I don't know that IRM could protect only Ms office file or to the overall file in windows such as the file create in QuickBook. I have the financial report in QuickBook file and what i want just allow the user to edit to the file in his profile but don't want to allow him to copy the file out of the computer.
How about auditing the file? Is it possible to audit the target file? For example, the date/time, user account that access the file... The behavior that make to the file such as rename, delete, copy... Is it possible to do that?

You can find in Group Policy
Remove Windows Explorer's default Context menu
Prevent access to drivers from My Commputer (You can select whitch drives)
Hide these specified drivers in My Commputer (You can select whitch drives)
and you must uninstall any FileManager (Or at least prevent the user to have the shortcut)
You said that you have disable CD burning featurs. But can you still burn with NERO?

Thank you very much for your comment. I will try to apply those setthing and check how secure it is to my financial file.
