Message-ID: <20010523173940.A1704@spotteswoode.yi.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Organization: private X-PGP-ID: 0x214190AF X-Stamper-To: post@stamper.itconsult.co.uk Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG besides ipfw(8) there is another popular firewall package: ipfilter (ip-fil3.4.17.tar.gz) by darren reed. like ipfirewall(4), it contains utilities for defining rule sets and administration. it's documentation states it to be part of freebsd systems versioned 3 and up, but i found no trace of it in my freebsd 4.0 STABLE. ipfilter is quite portable and the source distribution contains kernel source-patches for a dozen systems. [] is ipfilter just another interface to the kernels ip functions which can be used independently without interference? how do the systems interact? [] after applying ipfilter's patches to the kernel sources i lost my backups, which is unfortunate, because they were already patched with several sets, one of which was hand-crafted and can't be restored, so installing them from the cd-roms won't do. can i get the kernel sources for, say, freebsd 4.3, make a new kernel and run the 4.0 user-programs with it, i.e. would this be binary compatible? [] where can i find a set of kernel sources for freebsd-current? [] where can i find good and detailed HOWTO's, FAQ's and usage documentations? i need online-info about rules, the administration of firewalled systems and experience reports for all sizes and scales. clemens fischer ps: please Cc: me as i'm not a list member.
