It doesn't run on a Red Hat Linux release 7.3 (Valhalla) with the error: find: invalid mode `/4000'

RHL 7.3... released May of 2002... 7 years ago. I think it's time to update your system, don't you? However, if you read the man page on find, you'll see that /mode is the preferred way over +mode, but both are identical, even if +mode is deprecated.

Some companies can't or don't want to upgrade the distro that their software is based on.

Of course. That's why the cracker community flourishes as well as it does. They expect people to not keep updated on patching or upgrading their systems. The more systems that sit unpatched, the more reason for your suffering.

I'm not defending the practice ;) I just happen to work for a company whose product is based on a 7-8 old linux distro release. Although, we've updated and repackaged so many of the packages and rewritten many config scripts that, at this point, it is pretty much our own distro.

@atoponce: not every machine is connected to the evil internet, so often there is no need to upgrade the boxens every week...
