Where to find error messages for tc?
I'm having a strange situation where it appears that some 'tc class' replace/add commands being run by a script are not actually taking place; and when the script later wants to remove these classes, it dies because the classes don't exist.
The strangest thing is that if I run the commands manually, there's no error and as far as I can tell, it happens at random.
Is there somewhere I can see errors that may be logged by tc? The script is not reporting any error when it tries to add the class; tc simply replies with an empty response; indicating success.
Any thoughts welcome.
