Message-ID: <20021204215129.Q77087-100000@mail.econolodgetulsa.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I run netstat -i fxp0 while _innside_ a jail: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs fxp0 1500 10.10.10.10/ host 7908671 - 39559 - and then, I transfer a large file from the jail to some external host. Name Mtu Network Address Ipkts Ierrs Opkts Oerrs fxp0 1500 65.248.2.133/ host 7910577 - 41292 - The file I transferred out was 4.3 megabytes. Opkts only increased by 1733 ... which means 2481 bytes per packet ... but ifconfig tells us: # ifconfig -a fxp0: flags=8843 mtu 1500 that the MTU is 1500 bytes. So, am I missing something, or is something pathological happening here ? thanks. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
