I'm actually working on the TCP observation. I saw the article http://www.psc.edu/networking/perf_tune.html Then, I tried to change the system variables of FreeBSD 2.2.6 to obtain a large TCP window size. (1) First question. I want to make the RFC1323 works on FreeBSD 2.2.6. Is there any special procedure I need to do ? (2) Second. Once the (1) question resolved, How can I make TCP's option "Window Scale" work on any connection such as FTP ? (3) Third TCPDUMP, as a real good utility to observe the traffic on TCP connection, I really want to use this. BUT, But, whenever I launch this "tcpdump [enter]", it tells me, tcpdump: /dev/bpf0: Device not configured. I tried to change chmod 666 /dev/bpf0, but no succeed. What is the problem here ?

As long as 'tcp_extensions=YES' in rc.conf, then those extensions are enabled, yes. You can confirm with the command: sysctl net.inet.tcp.rfc1323 If it's set to 1 then it is enabled. > (2) Second. > Once the (1) question resolved, > How can I make TCP's option "Window Scale" work on > any connection such as FTP ?

You need to build a new kernel with pseduo-device bpfilter 4 in the config file.

It currently has an ISA 3Com EL III (3C509-Combo) card, which works fine. However, I have some DEC Tulip (21040) based EISA cards that I would like to use in this machine, since it is EISA. Has anyone gotten the de0 driver to recognize an EISA Tulip card? The man page says this is supported, but I can't get it to recognize the card. I tweaked some of the defines in the source code for the driver, but (so far) to no avail. Obviously, I have also been fiddling with the kernel configs. (I am *not* a programmer, let alone a device driver programmer.) It appears that this driver was written and subsequently modified to work on all of the BSDs; has anyone gotten it to work on _Free_BSD with EISA, not PCI?

I have a server P100-32Mb with FreeBSD 2.2.5 and two interfaces NE2000 on it. "ed0" interface is outside network interface and has two IP (193.232.26.20 - legal IP, 192.168.5.1 - local IP for SLIP connections), "ed1" is inside network interface and also has two IP (193.232.26.77 - legal IP, 192.168.0.31 - local IP for local LAN network). Also it have a 8-channel multiplexor with 8 modems for SLIP connections. As proxy server - DelagateD, and router - GateD 3-5-7. I want to start it server as a router and gateway for "ed1" network (legal and local IP too). I am edit the options "gateway="YES" and "routed="YES", "defaultrouter="193.232.26.17" from ed0 in /etc/rc.conf. Used "ports" GateD-3-5-7 as a routed daemon. For it gated.conf file (attach). But it didn't work as a router between two interfaces. I am read the GateD documentation and HandBook, but don't understand, where I am wrong.

One has to be *very* careful with the UDP_STREAM test and really only report the recevie rate. There are some systems and/or drivers out there which do not report ENOBUFs when the transmit queues overflow. [you may have actually reported the receive rate, I am just paranoid when it comes to the UDP_STREAM test...I very nearly did not include it in netperf ] If you were indeed getting 95 Mbit/s with UDP_STREAM, it is possible that the window size, even at 65535 bytes was not enought to deal with the latency of the connection. One first-order appoximation of the limit of performance with TCP is W/RTT where W is the window size, and RTT is the round-trip time. Some NICs have higher latency than others...there have been some NICs with really bad latency, which is one reason why there is a TCP_RR test in netperf. If there is high latency (high is a relative term) increasing the window can help. It is also a good idea to check the netstat stats for retransmitted segments. The occasional loss of a datagram will not show-up in the UDP_STREAM results, but it can in a TCP_STREAM test. rick jones -- these opinions are mine, all mine; HP might not want them anyway... :) feel free to email, or post, but please do not do both... my email address is raj in the cup.hp.com domain...
