Bluetooth mouse does not work after reboot
Hello,
I bought a Logitech V470 bluetooth mouse for my laptop. I followed this
website to configure mine :
http://astralblue.livejournal.com/357664.html
It had worked correctly yesterday (when I setup everything) now nothing
happens, after the reboot if I put the mouse in the association state it
does not associate with my laptop (the mouse led is blinking all the time).
There is no messages at all and bthidd, hcsecd are running too.
in my /etc/bluetooth/hosts I have :
00:1f:20:0f:62:31 mouse
in my /etc/bluetooth/hcsecd.conf I have :
[..snip..]
device {
bdaddr 00:1f:20:0f:62:31;
nameLogitech V470;

}
in my /etc/bluetooth/bthidd.conf I have :

I don't know how to compile a code file Here is how to compile in mit-scheme User’s Manual 4.1 Compilation Procedures cf filename [destination] [procedure] This is the program that transforms a source-code file into native-code binary form. If destination is not given, as in (cf foo) cf compiles the file ‘foo.scm’, producing the file ‘foo.com’ (incidentally it will also produce ‘foo.bin’, ‘foo.bci’, and possibly ‘foo.ext’). If you later evaluate (load foo) ‘foo.com’ will be loaded rather than ‘foo.scm’. If destination is given, it says where the output files should go. If this argument is a directory, they go in that directory, e.g.: (cf foo ../bar/) will take ‘foo.scm’ and generate the file ‘../bar/foo.com’. If destination is not a directory, it is the root name of the output: (cf foo bar) takes ‘foo.scm’ and generates ‘bar.com’. I can't understand .

Neither have been broken with their complete number of rounds. Versions of both can be broken with a reduced number of rounds. See http://www.schneier.com/paper-blowfish-oneyear.html for some analysis of blowfish, and e.g. http://www.schneier.com/paper-rijndael.html for several attacks on Rijndael with reduced rounds. It looks like both are viable choices today. Certainly good enough to protect your data in case of hardware theft. No encryption method is secure against lead-pipe cryptanalysis.

It's fully possible that a similar approach can be used for requesting a specific terminal width given in characters, rather than inches or centimeters (from a predefined value). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Keyboard repeat issues with Dell Optiplex 980s
We've recently upgraded a few desktop workstations from Dell Optiplex 960s to Optiplex 980s. We were running FreeBSD 8.1-RELEASE. The migration was performed by simply swapping the drives into the new systems. Immediately after switching people over, they all began to report bizarre keyboard issues - things like infinite key repeats (letters, numbers, enter) for keys they did not hold down. The key repeats continue indefinitely until another key is pressed. Occasionally, even mouse input will trigger similar infinite keyboard input repetition. In addition to the repeat issue, sometimes physical key-presses are not registered by FreeBSD, leading to typos and angry developers. We've tried doing fresh installs of FreeBSD 8.2-RC2 on two of these systems, and the issue persists. Because of the observed behavior, I'm thinking that this is due to new hardware in the 980s which isn't timing or handling interrupts correctly under the FreeBSD kernel. Looking at a 'pciconf -lvb' from each system, I noticed that the 980 has two USB controllers which probe under ehci(4), while the 960 (which does not exhibit this problem), enumerates six uhci(4) controllers and two ehci(4) controllers. To cut to the chase here, the 960 users' keyboards probe under a USB1.0 uhci(4), while the 980s only have ehci(4) devices to attach to. So, I guess what I'm asking is - has anyone else seen any keyboard repeat or other USB craziness with ehci(4) ports or otherwise Intel PCH controllers?Any fellow Optiplex 980 users?

Re: harddrive encryption
no at installation if you use standard installer. as i don't use standard installer at all, i don't have such a problem. i use any bootable FreeBSD media (actualy my own made pendrive), and then make labels, do newfs, mount, unpack files etc. if you can't do that then you may follow my advice install as usual, but make partitions like a: root - 10-20GB b: swap - as you need d: rest - don't allow to directory install on a and b. then after booting your system, and building and installing your kernel with GEOM_ELI inside: geli init -s 2048 (or 4096 whatever fragment size you plan) /dev/ad0d (or ada0d or how is your disk named). geli attach /dev/ad0d newfs options here /dev/ad0d.eli mount /dev/ad0d.eli /mnt cd /mnt tar --exclude /usr -cf - /|tar xpf - so you have copied all data except /usr to /mnt then edit /mnt/etc/fstab make ad0d.eli as root and ad0a as /usr then edit /mnt/boot/loader.conf add vfs.root.mountfrom=ad0d.eli then reboot to single user mode after booting /sbin/mount /usr - should mount fine cd /usr ls and delete with rm -rf everything except usr subdirectory then mv usr/* . rm -rf usr cd / rm -rf boot ln -s /usr/boot . then press CTRL-D and you have your encrypted system up. You don't have /usr encrypted as your software packages are not secred data. /usr is a: partition so bootloader boots from here. /usr/boot is linked to /boot to make it accessible for system programs as usual. but your /usr/local/etc may be secred so cd /usr/local mv etc /etc/local ln -s /etc/local etc this is how i configure my system everywhere i use geli. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Fully agree. In most cases, using big desktop environment *A* prohibits using programs of big desktop environment *B* and vice versa. So if the OP wants to use Gnome in the first place, he can go with Evolution or Sylpheed or Claws (as they are Gtk applications). The same problem appears when you're not using a desktop environment at all (instead a powerful window manager only) - but if you do, you traditionally will be very picky about the efficiency of the applications you use, so Bloatware doesn't have a chance. :-) I'm sure there are other GUI MUAs out there that are not so aggressive in inviting all their friends when starting up, keeping the system occupied for nothing. :-) I switched to claws, which seems excellent. I've been a Sylpheed user for many years and just a bit disappointed by the fall of speed and accessibility with the switch from Gtk1 to Gtk2. I do NOT want to say that text mode MUAs can't be easy to use, versatile, powerful and _FAST_. In fact, pine was one of the first MUAs I've ever used, and there's nothing about it's too complicated or other stupid nonsense. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

rusage and pthreads
Hi, I'm trying to figure out the interactions between rusage and pthreads. Peeking around in the kernel (7.2) I see updates occurring in various places. kern_clock.c, for instance, appears to increment the memory occupancy (*rss) counters. This would make it appear that every thread gets part of the count, but also that only the process that happens to have the CPU at that moment gets its count updated, even if it holds the memory. Am I misreading this? And the context switch counters also appear to be updated per-thread, but in mi_switch(), in kern_synch.c. Is this true? If the answer is yes, it's per-thread, then how does a process report its usages without putting the requisite code in each thread, along with the machinery to divert from whatever the thread is doing (even waiting on I/O) to get the report at (nearly) the same time in all threads? Is there a big design hole here?

This makes it impractical for an attacker to install modified software while geli is detached - although you are still vulnerable to hardware and firmware modifications. The other main advantage is that it prevents information leakage. If you just encrypt data, you should also give some thought encrypting the swap partition with a one-time key and using tmpfs. There's also /var/tmp which may be mitigated by setting appropriate environment variables to keep user data in home directories. Private information may leak through log or cache files. Some people think it's easier and safer to encrypt the lot. What do you folks think of the relative merits of AES vs Blowfish for disk encryption? At the higher levels of paranoia Blowfish's 64 bit block size is a cause for concern, but unless you are going up against serious crypto-analysis I doubt it matters much. However you may need to take account of performance. My fairly old cpu uses 100% of it's single core copying large files between geli partitions. Journalling makes things even worse. If you have cores and cycles to spare you probably wont notice, but it's still there. Blowfish is faster than AES, but some CPUs may be able to offload AES to hardware accelerators. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: rusage and pthreads
Chuck, I'm trying to figure out the interactions between rusage and pthreads. There largely isn't any-- struct rusage is per-process, not per thread. Peeking around in the kernel (7.2) I see updates occurring in various places. kern_clock.c, for instance, appears to increment the memory occupancy (*rss) counters. This would make it appear that every thread gets part of the count, but also that only the process that happens to have the CPU at that moment gets its count updated, even if it holds the memory. Am I misreading this? Nope. statclock() is fired off periodically (with some fuzz, to avoid clever games by processes trying to avoid being sampled) to update the stats for the currently running process. And the context switch counters also appear to be updated per-thread, but in mi_switch(), in kern_synch.c. Is this true? Probably. If the answer is yes, it's per-thread, then how does a process report its usages without putting the requisite code in each thread, along with the machinery to divert from whatever the thread is doing (even waiting on I/O) to get the report at (nearly) the same time in all threads? The process doesn't have userland threads updating this information. The kernel keeps track of it, and it updates the information periodically when the scheduler does context switches, when statclock() fires off, when disk I/O completes, etc. I'm looking at kern_clock.c::statclock(int usermode) The code in question begins struct rusage* ru; struct vmspace* vm; struct thread *td; struct proc *p; ... td = curthread; p = td-td_proc; and continues further down ru = td-td_ru; ru-ru_ixrss += pgtok(vm-vm_tsize); ru-ru_idrss += pgtok(vm-vm_dsize); ru-ru_isrss += pgtok(vm-vm_ssize); This looks to me like it's accumulating the data in per-thread counters. What's more, it's consistent with what I'm seeing on the user side. Note that this is 7.2; if 8.x behaves differently I'd like to know.

Re: rusage and pthreads
Chuck, I forgot to add: Nope. statclock() is fired off periodically (with some fuzz, to avoid clever games by processes trying to avoid being sampled) to update the stats for the currently running process. Which would mean that a process that is occupying memory but doesn't happen to be running on that clock tick doesn't have its memory counted toward the total ... right?

I wonder if all of the threads in a process might be pointing to the same struct rusage? Nope, checking kern/kern_resource.c kern_getrusage(), there is a per-proc struct rusage_ext which gets the sum of the per-thread td-td_ru counters via rufetch() / ruxagg()...so you're right that the counters are now per-thread.

Run it under gdb, look at the backtrace.

Since the environment stuff the script does is required for it to start, temporarily editing the script and running firefox3 is probably the easiest thing to do. Hmmm. OK. I did this: $ gdb /usr/local/lib/firefox3/firefox-bin 10388 This results in Firefox being locked and non-responsive to the user interface. It can't even draw the screen if I switch to that desktop, there's just a window frame hanging there. Even clicking the close button (the X in the top corner of the window) doesn't do anything... nor does right-clicking on the window title bar and selecting close. If I quit gdb, then firefox becomes responsive again. But it does put this in the console where I ran GDB (there's a lot). there are 11 [New Thread x (LWP y)] lines, and one error line.
