[Fwd: Re: Shorewall and SPARC]

I apologize for the long thread.  This was a discussion I had with the
shorewall maintainer for debian.  Might be a sparc issue?

I've never used Debian on Sparc hardware, so I don't know.  However,
according to Tom (the author of Shorewall), this is a common occurrence
on Debian and it has to do with iptables being built against an
incompatible set of kernel headers (as compared to the kernel against
which it is running).

If you try asking your question on the mailing list (and at least
mention that you have already been give an answer, but that you are
looking for more info), you might find a Debian+Sparc user who can help.
You might also try the netfilter mailing list, as this is not
