(It failed silently before.) You're matching for something, like a tcp_ACK flag, before doing something like an ip_len match. Since the latter comes first in the packet, you need to match for it first in your configuration. At least, that's what I recall the correct solution was. <snip> > I'm not sure when or why it stopped working, but I have a habit of doing > apt-get update;apt-get upgrade on debian unstable and not paying attention > to what gets updated.. so I may have gotten a new version of tcng without > realizing it. You did. You may wish to install apt-listchanges to view the full changelog for each package when you do an `apt-get upgrade` in the future. > Anyway, to get to the point, it is not obvious to me which line is causing > the trouble from that error message.

It's some line where you match into the header for some TCP, et al. option and then later try to match some IP header option. > Could any of you who are more familiar with tcng help me with this error? > > Thanks, > Jason > _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
