Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I was just thumbinb through the sysctl's of my freebsd -current box and a bsdi 3.1 box, and comparing the set sizes and options inboth sysctl trees on the OS's to the figures in vol. I of TCP/IP illustrated. What is the actual correct dflt MSS size? 512? or 536? Im asking for purely academic reasons. stevens says most BSD imlementations need to be multiples of 512 which ours is (512), but he also says if no mss option is found on the other end it defaults to 536. Whic is not a multiple of 512. I prefer ours of 512 sticking to the fact it has to be a multiple of 512, but on the other hand whats the point of setting our mssdflt to 512 if by default it goes to 536 if no mss option is found on the connection? Interesting indeed. Chris -- "I am closed minded. It keeps the rain out." ===================================| Open Systems Networking And Consulting.
