how to write a raw socket server using UDP
hello all, i m a new comer. i wrote a raw socket client using setsockopt (sock, IPPROTO_IP. IPHDRINCL, )using UDP. ihave followed MS_Press network programming . it is showing 19 bytes sent successfully. when trying to send more than 19 bytes using sendto(sock, ...) function , it is showing socket error on sending. i want to know how to write a raw socket server program so that to catch and display the data sent by the client. thanks a lot, keep fit, regards, spike.

Updated procstat(1)
Dear all, I've updated the procstat(1) kernel patch and userland tool; the updated version can be found at: http://www.watson.org/~robert/freebsd/20071127-procstat.tgz The new version includes a number of changes from the old version, including: - A number of bug fixes and cleanliness improvements in the layout of output, etc, including fixes for bugs reported by Skip Ford. - -a now means all processes, and the old -a has become -c, and the old -c has become -s. I.e., All, Command line and Security rather than Args and Credential. - Threads and processes are now sorted by pid and then tid. If processes are specified manually by pid, they are not sorted, although their threads will be. - A new -k has been added, which prints the kernel thread stacks for threads in a process (although not swapped out or actively running threads). This is extremely useful for answering questions of the sort But *why* is the process blocked in UMA. It has both a simple mode (-k_, which lists just kernel function names, and a slightly more detailed mode (-kk), which adds the offset into the function. The last of these required new kernel changes, including an MD component. I've tested the MD parts only on i386, although I have quick hacks at what they should look like on amd64, arm, powerpc, sparc64, sun4v. I don't promise these compile or work, but they might do. I think procstat(1) is getting a lot closer to commitable state for 8-CURRENT, but further feedback would be most welcome (including reports of success on non-i386 architectures, and possibly patches to fix them).

bin/118292: Add support to remove all msg/shm/sem ids with ipcrm
Hello, A friend of me has submitted this PR and I promised him that I would see if I could get it implemented. I couldn't find anybody directly responsible for the ips/iprcm tools, so I throw it in here for discussion. Description: I've observed that linux apps running under the linuxulator have a habit of leaving behind shared memory segments which are unused, but which eventually cause the system to run out of free segments and these apps will stop working. ipcrm(1) currently only allows removal of unused message queues, shared memory segments and semaphores on an individual basis, or those having a matching (non-zero) key. However it would often be convenient to just do a complete cleanup of everything, usually as root. The attached patch allows removal of all message queues, shared memory segments or semaphores by specifying an id of -1 (ala kill(2)). The code to lookup ids was taken from ipcs.

That said, the results to date have been extremely promising, and I anticipate that we will continue to find ways to better exploit multiprocessor hardware, especially in the network stack. I just want to add my 2 cents, that my recent experience with FreeBSD MP has been extremely positive. I tend to use highly CPU bound MP programs, typically lots and lots of floating point operations. It used to be that Linux beat FreeBSD hands down - now FreeBSD seems to have a slight edge! Basically my program runs about twice as fast when I run two threads as opposed to one - I cannot see doing any better than that! pure computation does not need kernel operations most of the time.. ie. multi-threading kernel wont help much ;) It has an indirect benefit by (presumably) not being in contention with the userland process, and not needing slap Giant on the whole system every few milliseconds.

handling pdfs?

What I'd kind of like to do would be able to perform cut'n'paste among different pdfs, 5 pages here, 10 pages there, until I put together maybe 100-200 pages, and sit back and read it. What I can't do is print just a few pages out of several 800-plus page specs, and perform paper cut'n'pasting. Is there some sort of util that will allow me to do cut'n'pasting among different pdfs, or at the very least, only to print certain ranges out of pdf docs, so I could do paper-wise cut'n'paste?

I think procstat(1) is getting a lot closer to commitable state for
8-CURRENT, but further feedback would be most welcome (including reports of
success on non-i386 architectures, and possibly patches to fix them). For
FreeBSD developers with P4 access, you can also check out
Thank you for this. I think procstat(1) is going to be very useful.

Re: Updated procstat(1)
Robert Watson wrote: I've updated the procstat(1) kernel patch and userland tool; the updated version can be found at: http://www.watson.org/~robert/freebsd/20071127-procstat.tgz The new version includes a number of changes from the old version, including: - -a now means all processes, Thanks. :-) I'm a little surprised. You seemed pretty dedicated to a per-process tool. I personally would change it to allow either the all flag or a list of pids, rather than at least one of. For pathname, command-line, and credential information, the output will likely not change between showing the pid in the all output and the list output so you're just outputting it twice. If one really wants the same pid to be output multiple times for threads, kstack, or file descriptors, then I'd expect procstat -k 0 0 0 0 0 to be more useful for that. I would think a mistake in usage has been made if a list of pids is specified along with the all flag. But, no real harm is done by doing it the current way. - Threads and processes are now sorted by pid and then tid. If processes are specified manually by pid, they are not sorted, although their threads will be. Nice. - A new -k has been added, which prints the kernel thread stacks for threads in a process (although not swapped out or actively running threads). This is extremely useful for answering questions of the sort But *why* is the process blocked in UMA. It has both a simple mode (-k_, which lists just kernel function names, and a slightly more detailed mode (-kk), which adds the offset into the function. This is excellent. Does this absolutely have to depend on DDB and KDB? The last of these required new kernel changes, including an MD component. I've tested the MD parts only on i386, although I have quick hacks at what they should look like on amd64, arm, powerpc, sparc64, sun4v. I don't promise these compile or work, but they might do. In sys/amd64/amd64/db_trace.c on line 537, change SWWAPPED to SWAPPED. The newly introducted function stack_save_td() doesn't panic in the MD powerpc code like it does for other arches. I have no idea if this is correct, it just doesn't match the others. Unfortunately, I can only test i386. -- Skip ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
