Libs/Deps required for RedHat UDP?

[DailyDose]

Hey all, I have a Red Hat machine that I am using as my test/development box and I am having issues communicating when using UDP.  We have various Red Hat servers that are running the exact same program, but an earlier build (very minor, if any, changes), and are having no issues.  It's been a few years since this thing went into production and in that time, the Linux IT guys have changed and ours do not know the answer to this question.  Are there libraries/dependencies necessary to make LabVIEW 2011 capable of using UDP to communicate?

As far as I know.the socket library for the interface that LabVIEW uses for its network interface functionality is part of libc and from there accesses kernel functions. It would seem unlikely that you can omit certain dependencies that would cause such errors without compiling your own kernel image with these functions being disabled.

More likely this is some tightening of the security settings in the firewall rules for your Linux installations.

You're correct.  The Firewalls were apparently blocking it.  Man that's annoying.  Thank you!
