Tony, If your Linux kernal will run the RedHat executables, then I'd suggest grabbing the Nharp executable from the binary distribution and seeing if that has a similar result. If so, then it is likely a configuration issue. If my binary works, then it would be a peculiarity with the OS environment. You might try ensuring that all files under $NAWIPS have read access by the user running Nsharp, incase something is messud up there. Try: cd $NAWIPS chmod -R a+r * Some Linux users have found that the user account configurations create problems with groups.
