Throughput computation given cwnd and transmission time values?
Hey guys. :) Anybody have any idea how to compute for the throughput of a connection given the congestion window size of each segment, but not given the RTT? (I'm using TCP Reno as my protocol flavor.) My log file doesn't provide the individual RTT values, but I have the total transmission time though. When I sum the total congestion window size of the connection and divide it by the transmission time, I get unbelievably high throughput values like 20MB for my 802.11b connection, which I think has a ceiling of 11MB. Any form of reply will be extremely appreciated. Thanks in advance, Jamie __ Yahoo! Music Unlimited Access over 1 million songs.

Yeah, I tried that too.

Sending files to Win/Linux client from FreeBSD server?
Hi everyone :) I'd just like to ask if there's a specific command I can use to send files from my FreeBSD 4.3 server to my Windows XP/ Red Hat Linux clients. I'm totally stuck to mounting and unmounting a floppy disk and transferring the files by copying and pasting from PC to PC. There's got to be an easier way, but I can't seem to find anything on Google. Please help me. Thanks in advance, Jamie __ Do You Yahoo!? Tired of spam? Yahoo!

Re: Wireless access points for FreeBSD 4.3?
--- Chuck Swiger [EMAIL PROTECTED] wrote: Anyway, if you are stuck using 4.3 for unimaginable reasons, I suspect the atheros or PRISM-2/2.5 chipsets are what you are looking for. Yeah, I'm stuck using 4.3. I'd update if I could, but unfortunately I can't. Your question doesn't make it entirely clear whether you are looking for a wireless card/NIC for a FreebSD machine to talk to a base station, or whether you are having an issue sending traffic to or from a wired FreeBSD machine to some other Linux box via basestation to wireless...? I'm sorry, I assumed wireless access point = base station. Yes, I'm sending traffic from a wired FreeBSD machine to a wireless Linux box via a base station. It may be the case that you want to bridge or NAT a wireless subnet onto your LAN, but you should consult your basestation's docs for how to do that; FreeBSD would use nothing but normal TCP/IP routing to the basestation. Please correct me if I'm wrong... FreeBSD 4.3 doesn't care what type of base station I use, as long as I can configure the base station to make them see each other? 'Cause that's my real problem, as we only have relatively new base stations in the lab, and I don't know if 4.3 will work with them. If they won't then should I start scrounging about for older base stations?

Wireless access points for FreeBSD 4.3?
Hi, I've been searching the web for compatible wireless access points for FreeBSD 4.3. As of yet I've been unsuccessful in finding any kind of list. However we do have the following base stations in our lab: D-Link DI-524 Netgear ME 102 MS MN-500 Is there any way I can configure my FreeBSD 4.3 server to see any one of these? The set-up is, my server and base station are connected to a wired network, and then I have a wireless client running on Red Hat Linux 9 contacting the server through the wireless access point. If the models are too new for 4.3, can you instead recommend access points that *are* compatible? Thanks in advance, Jamie __ Do You Yahoo!? Tired of spam? Yahoo!

Linksys WMP11 on Freebsd 4.3
Hi, I would just like to ask if there is any way at all that I can configure the Linksys wireless PCI card (WMP11) to work on Freebsd 4.3? I know the card's not compatible, but if I can't make it work I'll have to buy a wireless card that IS compatible and I'm hoping I wouldn't have to do that. Any help at all would be appreciated.

freebsd kernel 'make' failed : undefined reference to...
Help! I'm a UNIX newbie trying to compile a custom kernel with modifications for TCP purposes. My system is FreeBSD 4.3 running on i386. My 'make depend' works fine, but when I geto to 'make', the following error occurs: tcp_usrreq.o: In function 'tcp6_connect': /usr/src/sys/compile/MYKERNEL/../../netinet/tcp_usrreq.c(text+0xfa5): undefined reference to 'tcpstat' The error repeats for other tcp*.o files, like tcp_output.o, tcp_subr.o, tcp_timer.o, and even in6_proto.o. There are undefined references to 'tcp_mssopt', 'tcp_delack_enabled', 'tcp_ccgen', 'tcb', 'tcbinfo', 'M_TSEGQ', 'tcp_mss', and 'tcp6_input'. Most are common to the tcp*.o files. What should I do?? Googling gives me different answers for this error, answers I don't even understand. Anyway if you could help I would be really grateful. Thanks! __ Do you Yahoo!? Yahoo!
