Yes, it supports data compression, and it's enabled by default. See the pppd(1M) man page for details. Note that compression schemes need to be built into your kernel, so what's _actually_ supported depends on what kernel modules you have. The debug log messages will be helpful here as well, as they indicate which compression algorithms are being negotiated. I'm not sure what sort of testing you want to do with it, though, so you'll need to be more specific. For what it's worth, I find that passing large amounts of highly-compressible data (such as the letter "A" repeated a few million times in a file) is one good stress test, and passing incompressible data (such as a large bzip2'd file) is another. Each explores a different end in the usual string-based data compression algorithm. The Canterbury Corpus is another fairly well-known test, and is probably a good middle-of-the-road test for passing compressible data. But there are other forms of "testing" that are possible here, including performance and interoperability, and those may require other sorts of testing schemes and other considerations, so I'm not really sure what it is you're after. -- 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
