Hi, I'm very interested in this, great work! :-) I can't load the kld on my Sun Sparc, I think I messed up ld yesterday trying to patch for a bug that show's in firefox and mozilla. It compiles, just doesn't run. As soon as I have it up and running I'll give you feedback.
Have you tested it with pf? If so can you give me some examples? I'm particularly interested in this for doing packed shaping, especially on P2P. Thanks for your work! On 6/10/06, Vadim Goncharov <[EMAIL PROTECTED]> wrote:
Hello All! I wrote new netgraph(4) node, called ng_tag, able to match packets by their mbuf_tags(9) and assign new tags to mbufs. This can be used for many things in the kernel network subsystem, but particularly useful with recently added ipfw(8) tag/tagged functionality (will be MFCed to RELENG_6 after Jun 24). With this node, in conjunction with ng_bpf(4), I was able to match and block (perhaps shaping is also possible, but this relies solely on ipfw) DirectConnect P2P data connections traffic - you know, they're using random ports, so you can't match them with usual firewall rules and must check data payload contents of the packets. See man page for example of how to do this. Download files from here: http://antigreen.org/vadim/freebsd/ng_tag/ Then do: make kldload ./ng_tag.ko Man page can be viewed as: cat ng_tag.4 | /usr/bin/tbl | /usr/bin/groff -S -Wall -mtty-char -man \ -Tascii | /usr/bin/col | more -s Please especially test tags with non-zero tag_len, if you can (though it's not needed for ipfw). P.S. BTW, what is correct subject prefix for new contributions? I think [PATCH] is not correct as these are new files, not patch :) -- WBR, Vadim Goncharov _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
