Packet filtering for pornography blocking

Thanks for your prompt reply.

We have one problem.
windows version is intended to be for single system.
for nat (internet sharing) packets can clearly be identified as being “forwarded” (am I correct?)
what if the local system is running a proxy server? the connection will be as if from local system. Can we identify those packets (from proxy)?

how about third party connection sharing software? how are the packets identified as?

Thanks in advance.

Hello again,

We have procured software from your company.

We have a problem for installation script on vista.
when we try any of the following commands as mentioned in the installation help,
snetcfg.exe -v -l ndisrd.inf -m ndisrd_m.inf -c s -i nt_ndisrd
snetcfg.exe -v -u nt_ndisrd

the commands are failing with error code 0x80070005

We have done everything as per the help. disabled driver signature enforcement option. all files are in single directory. tried on different computers. logged in administrator account.

we are using vista home.

Please do the needful.

Regards,

Anil Chandra K

1) Are you trying to install on Vista x86 or x64?
x86 – vista home is x86. we dont have x64 right now. (we ordered)

2) Have you taken the correct drivers, INF files and snetcfg matching the OS (32 bit driver for x86, 64 bit for x64)? May be the problem in snetcfg tool if you have taken the original version from DDK instead the modified one we use.

We are using snetcfg and other files from installation of winpkfilter.
After installing winpkfilter on vista, there is a directory (winpkfilter frameworkkerneldriver). the snetcfg tool and other files are taken from that directory.

3) Commands mentioned should be executed under Administrator account. You have mentioned that you tried, but I would recommend to recheck.
We have cross – checked the admin account. we are using under *administrator* account.

4) And the last, if you run WinpkFilter run-time installation does it install normally?
the winpkfilter installation on vista (x86) is installed smoothly and I am able to run test applications successfully.

going through reference install script will help. as we may be doing something wrong.

here are the steps we followed.

1) installed winpkfilter on vista x86.
2) copied winpkfilter frameworkkerneldriver directory.
3) uninstalled winpkfilter s/w
4) tried to run snetcfg from the copied directory on the same machine.
5) copied directory to second vista system and tried to run snetcfg from the copied directory.

both (4) & (5) steps failed with error code 0x80070005

6) repeated (1) to (5) on two different vista systems… unsuccessfully.

please send the install script.

Hello,

Thanks for the installation script.

Though we use different installation script, I studied the install script sent by you.

1) Filename: “{app}Kerneldriversigndrv.bat”; Parameters: “save”; StatusMsg: “Saving current driver install policy…”; Flags: runhidden
the signdrv.bat does not take parameter “save”
i get the error “Usage: signdrv.bat when I run that.

2) I get the same error for “restore” parameter.

i checked the signdrv.bat file to see the script. there are no options for “save” and “restore”. But my question is how they are successfully executed during installation of winpkfilter?

3) I found a set of files in winpkfilter frameworkkernelbinimdrvamd64 except for snetcfg, I tried to execute. without success.

I have following questions.

1) am I using different files?
I am sending the files to you. just check if I am working on correct files

2) when I use command prompt in vista, are the commands run as administrator? I dont understand windows as much 🙂

3) are the drivers different for amd machines? i am using amd processors for both the vista systems I am using. But if that is the case, why is the winpkfilter installation successful?

Thanks in advance.
