tcp open connection works only if root

[supermaz]

It worked on RedHat 8. It doesn't work on RedHat 9. Anyone experienced the same problem?

This is normal default for linux. You may want to set the SUID bit on the tcp/ip open connection.

.... mmmm .... so why is it working on redhat 8.0?
BTW what do you mean exactly with "set SUID"? on a labview function???

Greetings again!

SUID isn't a Labview function; it's simply a file permission function in Linux. You might want to find the actual executable that opens when you request a tcp/ip, and see what the permissions are. Did you install Labview as root or as a user? This could determine how the default permissions were set.
Just a few things to check. If it Does work as root, then it's almost certainly a permissions issue.

Hi,
thanks for the answers but I found the solution and I can say that it has been a real hassle. The problem is due to the new POSIX thread library implementation that comes with redhat 9: users should disable the new NPTL implementation by issuing
export LD_ASSUME_KERNEL=2.4.1
prior of executing labview. The strange thing is that RH9 and LabView 6.0i works even with NPTL support enabled.
