| |
Hi everyone,
I've patched both the kernel and the ppp(d) distribution to support in-kernel packet filtering by the PPP driver. This allows you to restrict the packets that pass over the link, or to prevent certain packets from resetting the idle timer. The latter is useful if you rely on the idle option to bring your link down, but don't want e.g. DNS queries or routing information to prevent that from happening. See the pppd(8) man page for details, specifically, the bits on the active-filter and pass-filter options.
This is an 'alpha' release -- it's not my intent for this to be included in the official kernel or ppp(d) distributions (yet); I'd rather a few kind souls tried it out first <g>
The patches and usage instructions are available from <URL:http://www.loth.demon.co.uk/ppp/ppp.html>.
