Message-ID: <20020204120158.A1583@nomad.lets.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Howdy! The following is from netstat -s on a busy NFS client (udp mounts) I was wondering about the line 172764 dropped due to full socket buffers in the "udp" section. Will increasing kern.ipc.maxsockbuf: 262144 help with this? Also will increasing net.inet.udp.recvspace: 41600 help with udp in general? thanx - steve netstat -s udp: 907568372 datagrams received 0 with incomplete header 2 with bad data length field 1 with bad checksum 0 with no checksum 1852 dropped due to no socket 9 broadcast/multicast datagrams dropped due to no socket 172764 dropped due to full socket buffers 0 not for hashed pcb 907393744 delivered 907648708 datagrams output ip: 2433057204 total packets received 0 bad header checksums 3 with size smaller than minimum 0 with data size < data length 0 with ip length > max ip packet size 0 with header length < data size 0 with data length < header length 0 with bad options 0 with incorrect version number 531096217 fragments received 0 fragments dropped (dup or out of space) 1304 fragments dropped after timeout 110782591 packets reassembled ok 2012140956 packets for this host 571538 packets for unknown/unsupported protocol 0 packets forwarded (0 packets fast forwarded) 0 packets not forwardable 0 packets received for unknown multicast group 0 redirects sent 2061766141 packets sent from this host 0 packets sent with fabricated ip header 0 output packets dropped due to no bufs, etc. 0 output packets discarded due to no route 7447090 output datagrams fragmented 36843330 fragments created 0 datagrams that can't be fragmented 0 tunneling packets that can't find gif 0 datagrams with bad address in header To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
