Only if you can be more specific in what sort of guidance you need, and if you've already read through the existing documentation and still have questions. Otherwise, and no offense really intended, it's likely not to be a useful way for either of us to spend time. What "ppp-extension" are you talking about? Are you talking about the configuration options? The various basic PPP control features? The system-specific kernel modules and features? The possible add-on features? Or something else? As with other questions, and as I mentioned before, if you have a question about the documentation or about some error or debug message you're seeing, __please__ include a copy of that source material with your question. Providing more context would help. Based on the messages you've posted to the list so far, and my experience in the area, I suspect you need a different kind of assistance than I think you'll find available for free on mailing lists. I strongly recommend (as I did in a previous message) searching out organizations and products that can simplify your job. Surely, your time is worth something to you, and spending it on a reinvention of someone else's wheel can't be a good thing. The UNH IOL has both interoperability and conformance tests available for vendors at a very reasonable rate. I highly recommend them, and I know some of the folks there if you need pointers. In addition to the IOL, there are also commercial devices available that will do validation tests, such as IxANVL. They're by no means "simple" to operate and interpret, but they're much simpler and more effective than attempting to roll your own tests. -- James Carlson 42.703N 71.076W <carlsonj@xxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
