InetPing

[Ilanx]

Hello,

In my program ,I  need to ping a couple of PC's.

I use InetPing() function. On 3 different IP addresses indication was "machine is availeble",  but the fourth IP returns 0 meaning machine is not available.

i tried different timeout values.

But the regullar windows Ping.exe always works with this IP.

I use CVI8

Any idea how to solve the problem.

Thank you in advance.

Hi llanx,

Thank you for bring this to our attention. Is the fourth machine a 64 bit system. Our internal document indicates that the InetPing() function did not work on 64 bit systems. This issue has been fixed since CVI 2009. I hope this helps.

Regards,

Hi Josh,

Thank you for the quick response.

I checked the fourth machine (actually all of them are servers). It's an 32 bit Microsoft Windows Server 2003 R2.

used on AMD Opteron processor.

Rest of machines different models of servers but with 32 bit system.

Thank You

Hi llanx,

Thank you for the update. I think the AMD Opteron is a 64 bit processor. Below is the wikipedia article on this processor for your reference.

It looks like this machine is running with a 32 bit image on a 64 system.

Hi llanx,

What version of the CVI runtime engine are you using? Are you ok with installing the latest version of the runtime engine?

The runtime engine is free to all of our customers and they are backward compatible. Hopefully, this bug is fixed with a newer runtime engine.
