Hi,
I have the following issue:
For an experiment I want to redirect requests from a device to a specific web address to a different system.
It concerns an embedded device that can connect to a number of websites, and for one of them I do want to redirect the traffic to a different server.
As it is an embedded device I cannot change the address or make local adaptations.
E.g. just adding the name of the website to the hosts file is not an option.
Anyone a clue on how this is easily achieved?
For now I have considered the following alternatives:
- run my own DNS server, tell the device to use that one and redirect that website to a different IP address and all other addresses to the "real" dns server. Not really sure if this is possible though (since I might have to serve the complete zone, instead of just redefining the one adddress).
- use modified Socks based proxy for this. Not too sure if I can find sources for this and not too sure if this will work as I am already behind a proxy.
- maybe trick my router (linksys wrt54g) into doing something (not really preferred as I would like a generic solution).
If you have suggestions on what would be the easiest (or see other simpler approaches) please let me know.
Thanks alot, Frans.
PS: this might be off-limits for this forum, but if there is a very simple linux-based solution that is definitely something I'd like to consider.

Found a solution inbetween.
I just set up posadis on a PC.
Posadis is an open source DNS server.
One can simply configure it as a caching DNS server (which just means it redirects DNS requests to another server and caches the results for later usage.
However with posadis it is possible to preload the cache. The original idea is that you could redirect addresses that you do not want to other addresses (e.g. 127.0.0.1). (so a form of blacklisting).
This could also be used to whitelist an address and specify its IP address upfront, which was exactly what I needed.
I installed this on a PC, configured the embedded device to use the DNS server running on the PC and all was set. Only thing I did not manage was to use this in combination with a proxy (as in that case the device immediately sent all its traffic to the proxy).
That was no big deal for me though.

Besides "Oracle OLAP Agent" and "OracleServiceORCL", what other services does Oracle use on Windows?

Thanks, but most of the pages returned by that search I had already visited.

If we disables anonymous access, windows launch an alert box of user name and password for authentication. Can anyone plz tell me that
1- Which mechanism is used by windows to launch this alert or message box
2- Which dll file is called by windows operating system during this authentication mechanism?
Please help me...

It wants you to use Windows Authentication by default if you turn off anonymous access. This is the same thing that happens when you log in to the network. It talks to the domain controller and authenticates you for the network. It (sometimes) asks you again if you try to connect to a server without anonymous access, particularly through a browser.
I do not know which DLLs are responsible for this. You can't hack them anyway. That would be bad...

Is this what it has come down to? Any question about how the system works inside is automatically deemed to be rooted in malicious intentions?
I recently posted a question about how the OS uses the BIOS, and people started assuming I was a virus writer.

No, I'm just saying you'd probably break the system if you tried to change it even slightly. Because Windows doesn't like it... not because it's morally wrong or something.

Your keyword: GINA.

What? Did I miss something? What is the meaning of that?

GINA is the name of the subsystem used by XP and previous versions for logging the user onto the system.
Do an MSDN search for GINA and you'll see.

The dialog is created - in XP and later - by the CredUIPromptForCredentials function.

You need to be a little more specific. Are you trying to access a network share, or a website? If it's a network share, then you'll be looking at SSPI challenge-response authentication, using NTLM or Kerberos, and LSASS.exe as the file that's handling it.
If it's a website, it could be attempting to use NTLM/Kerberos, or it could be using basic authentication. These two work in very different ways - Googling for IIS authentication methods will help you here.

Hi All,
Currently I am working on deployment of our application on Windows Vista based PC. The installer supplied by us is supposed to install a OPenSSH sever on the target machine and start it so that it is available for all users of the system. Till Windows XP it was fine but with Vista things have changed. The service is not getting started on Vista PC. I have tried various methods to make it work but none of them worked. Please if someone has an idea what could be the issue do let me know.
For you information I am using Installshield Professional 12.X for makining our installer. The following are the methods I have tried till now
1. Raising the elevation level of the installer exe (marked it as requireAdministrator)
2. Raising the elevation level of actual serivce (marked it as requireAdministrator)
For the above two I have embedded the modified manifest file. The one generated by the Installshield has privelege level set as "highest available"
If I am a member of admin group and I execute an installer exe which has embedded manifest containing requested privelege as "require administrator" then Vista UAC does not prompt me for elevation this means that the setup program is running with full admin priveleges. So any process started by it should also be running with admin priveleges, right?
Now once the installation is done and the setup ask to reboot the machine so as soon as the process exits I am back to standard user. So the next time I log into the machine I will be a standard user, however the service requires AdminPriveleges hence it did not started.
So how do I make my installer to install the service properly so the next time I or any user logs into the machine the service is in started state?
Does anyone is aware of some tool that shows me what is the difference when executing the application/service in WinXP Compatible mode. If I run my SSH server in WinXP compatible it does gets started and is available for all the users.
Can someone please let me know where I am going wrong? I do not want to do various group policity settings or run an application in compatibility mode.
Thanks and Regards

This:
1. Raising the elevation level of the installer exe (marked it as requireAdministrator)
2. Raising the elevation level of actual serivce (marked it as requireAdministrator)
Is going to piss off Vista in a big way. You need to make your service run in user mode. We need to get out of the habit of thinking that our programs need to run on an admin or system account. I was fairly impressed by this take on the issue:
http://www.interact-sw.co.uk/iangblog/2007/05/09/uacproblem[^]
With a service, maybe this doesn't have as much weight, but it's something to think about. I've completely changed my company's software because of this. Our software was pissing off Vista in a big way, but some small changes made it so the installer runs with no UAC warnings, and the program runs and self-updates with only one prompt to the user - "do you want to update now or later" - no annoying UAC pop-ups happen. I am using an MSI installer and a Clickonce installer. The users have the choice of choosing either download, whichever one works better for them, and after the first install, it updates itself.

Hi all,
Is a option in windows to control volume by shortcut keys ... if not is there any other way to control volume using keyboard...
Thanks in Advance............

There is no such option. My laptop has fn-key combos that mute and turn the system volume up and down, plus it has a wheel that I think is just a straight-up dimmer pot on the speaker circuits. I also have little buttons on the side that control pause and play, and skipping forward and back, but I've never actually touched them so I'm not sure what they do 
I think you can get 3rd part plug-ins that will let you do this, but I don't know the name of any. Sorry I couldn't be more help.

I need to write a debugger which will execute an process and I need to get notification when that process will write or modify any thing on the hard disk. Can we keep watch on any process for getting info when that process will write to hard disk? I have read something about "Win32 Debug API". Can any one guide me or give me any demo code for this?

Why do you post this question in so many forums? Isn't one enough?
And why write it yourself? There are good programs for this already.
