ports (audio) candidate
http://www.speech.kth.se/snack/ I came across this today. It compiles and runs under freeBSD ok, bit seems to have some small hickups and stuff I can't figure out. If there is a tcl/tk guru out there who can take a quick look.. This is a rather awesome sound analysis program designed to allow analysis for voice-recognition work. Seems to "Almost" work.. It keeps complaining about "losing focus" and occasionally core-dumping here.. A TCL expert may know the 'trick' needed to make it a reliable port. particularly the "wavesurfer" program. -- ++ __ _ __ | __--_|\ Julian Elischer | \ U \/ / hard at work in | / \ [EMAIL PROTECTED] +--x USA\ a very strange | ( OZ)\___ ___ | country ! +- X_.---._/presently in San Francisco \_/ \\ v To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
Re: Should URL's be pervasive.
Oh god, as everybody else is saying, I can't believe I'm getting involved in this, but... On Fri, Aug 31, 2001 at 09:58:21AM -0700, a little birdie told me that Richard Hodges remarked Why not parse it literally? For instance, http://www.ufp.org would imply TCP, dest port 80, and host www.ufp.org. For ping, that would imply that I want to test the three-way handshake on whatever is listening on port 80 at www.ufp.org For traceroute, I want to send a series of TCP SYN packets to www.ufp.org, port 80 with increasing TTL values. Perhaps this No, it doesn't. http://www.ufp.org/ does NOT mean TCP port 80. www.ufp.org:80 means port 80, I don't know of any simple common way to say TCP. http://www.ufp.org/ means the host 'www.ufp.org' using the protocol 'http' with the TCP port 80 implicity as a result of the 'http'. Traceroute is not going to use HTTP. Ping is not going to use HTTP. Rpcinfo is not going to use HTTP. A mail client is not going to use HTTP (this one is perhaps debatable, but I'm sure as hell not going there). If you want to take a URI passed to 'ping', say, and parse out a hostname, that's one thing which I'm sure we could have endless disagreement about.

gzipped crashdumps
Anyone else think this patch from NetBSD is worthwhile?
Should I also extend it to support bzip2'ed dumps now that that's in
the base system, or would that be overkill?

FreeBSD Monthly Development Status Report -- Request For Submissions
It's that time again! I'm in the process of preparing the August, 2001 FreeBSD monthly status report, and as such am interested in seeing submissions in much the same style as previous months. Generally, this means about one paragraph of text per project describing events that have occured since the last status report (or two paragraphs for new projects, so as to introduce them). Large projects can be broken down into multiple sub-projects with seperate reports reports. If multiple developers are working on the same project, they should coordinate so as to submit only one report (or split it up into parts as appropriate along logical boundaries). Reports should relate to the FreeBSD Project, but are not limited to on-going software development: documentation, public relations, management, application developer relations, technology transfer, etc, are all relevant. Please submit reports in the following format: Project: (name here -- required field) URL: (URL, if any, here -- omit field if none) Contact: (name and e-mail address of one or more contact points -- required field) One paragraph on the topic of project status since the last report, indented two spaces, and wrapped at column 78. Plain text only, please. Please send submissions to: [EMAIL PROTECTED] The deadline for submissions is September 7, 2001, at 3:00pm EST. The report will be released soon thereafter.

Routing Performance?
The new P4s are shipping with 800mhz RAMBUS memory modules. Wouldn't 2GB of 800mhz RAM go a long way to evening out the performance between a PC/FreeBSD box and all but the most specialized, packet-pushing ASICs?

SO_REUSEPORT on unicast UDP sockets
Hello!
According to UNPv1 SO_REUSEPORT on UDP sockets can be used to bind more than
one socket to the same port (even with same source ip address). But quick
look on /sys/netinet/udp_usrreq.c function udp_input() shows that this will
work as expected (data stream duplicate) only on multicast/broadcast local
addresses. Please pay attention to the following code fragment comments:
if (IN_MULTICAST(ntohl(ip-ip_dst.s_addr)) ||
in_broadcast(ip-ip_dst, m-m_pkthdr.rcvif)) {
struct inpcb *last;
/*
* Deliver a multicast or broadcast datagram to *all* sockets
* for which the local and remote addresses and ports match
* those of the incoming datagram. This allows more than
* one process to receive multi/broadcasts on the same port.
* (This really ought to be done for unicast datagrams as
* well, but that would cause problems with existing
* applications that open both address-specific sockets and
* a wildcard socket listening to the same port -- they would
* end up receiving duplicates of every unicast datagram.
* Those applications open the multiple sockets to overcome an
* inadequacy of the UDP socket interface, but for backwards
* compatibility we avoid the problem here rather than
* fixing the interface. Maybe 4.5BSD will remedy this?)
*/
Is there still any real need in such backward compatibility? Can such
functionality be added (fixed) with possibility to switch it off using sysctl
or kernel-build option?
I find such possibility realy useful at least for NetFlow data processing and
believe that it would be useful for many UDP-based protocols.

Vladimir.
