Re: ssh with bridged ap
Again, your /var/log/auth.log should be very helpful in this matter. Connect on your server with WIFI then do this: tail -f /var/log/auth.log Then, try to connect using the wired connection and see if you get any logs. If you do, post them here :) If you're connecting from a non-windows box, please pass the -v flag to your ssh client to toggle verbose output and post that here too.

Recommended SWAP space for large amounts of ram (8GB)
Good morning all, Each operating system seems to have different documentation regarding what a decent swap size is for systems with large amounts of RAM. My system only has 8GB of RAM. Some people have gone with the general idea that 2X the amount of RAM is sufficient but for systems with large amounts of memory 1X the amount of RAM is fine. I was also told that anything over 2GB of SWAP space will cause performance issues on the system and that it is not recommended.

The old rule of thumb of swap = 2 x RAM dates back to the days when
128MB RAM was a big deal. Nowadays, you're likely to have that much in
your phone, and systems with 128GB RAM are not unknown.
In these days of plentiful RAM, the new rule of thumb is if you're
swapping, then you're doing it wrong. You don't need anything like as
much swap nowadays, at least, not as compensation for lack of RAM. You
may need swap to back eg. tmpfs filesystems. You don't need swap
nowadays for system dumps -- any partition with ephemeral data (or no
data at all) can be used for dumping, and given that minidump capability
exists now, you don't even need to supply the 1 x RAM + delta required
for a full dump.
That swap 2GB resulted in performance problems was certainly true
once, but I doubt very much that it is still the case in HEAD or the
upcoming 9.0-RELEASE, nor probably in {7,8}-STABLE. IIRC the problem
was due to avoiding integer overflow in some calculations deep inside
the VM system, which is usually not a hugely difficult problem to fix.
My recommendation: for systems with 1GB RAM or more, and that don't make
heavy use of memory filesystems and the like, then 2GB swap is ample,
and you can probably get away with as little as 1GB at need.
Cheers,
Matthew

Thinkpad audio question
A friend of mine has an IBM T500 Thinkpad which is nearly identical to the one I have. We both have interesting audio issues. Any ideas as to why the problems explained below exist would be greatly appreciated.

However, the speaker audio is muted when the headphones are plugged in. I have tried two different head sets to rule out flawed hardware. My friend's T500 is more up-to-date than mine (likely 8.2-STABLE) but in his case headphone audio works perfectly and he has had no luck in getting audio out of his built-in laptop speakers.

I think your response follows the excellent pedagogical principle: a little inaccuracy saves a lot of explanation. But... disk is still (by far) the cheapest commodity, and the opportunistic paging algorithm manages VM very well. VM is not by any means obsolete, and seeing paging behavior is not a sign of a misconfigured system. Well, yes. I was certainly glossing over a lot of complexity -- but I would maintain that I am fundamentally correct. Having some pages swapped out is absolutely not a problem. True. In fact, it's a positive benefit: swapping out memory pages that are exceedingly rarely referenced makes more room in RAM for more actively used pages. On the other hand, having pages continually swapping in and out definitely is a problem in terms of performance, given that disk IO takes of the order of milliseconds, while reference to main RAM is of the order of microseconds or less. Orders of magnitude faster. Now, while disk may well be the much the cheapest storage medium available, that's only part of the expense. In fact, up-front capital expenditure on the kit (perhaps several thousand pounds/euros/dollars) is outweighed by the operational expense (power, cooling, hardware support etc.) over the life of the equipment, so spending a bit more (capex) on components that run at lower power (opex) makes a lot of sense. Even more, if the server is being used for eg. e-Commerce, then the volume of the transactions and the data processed by the server makes all the difference to your margin: the more you can do with the same hardware - viz, the more efficiently and faster you can make the hardware run - then the more profit you make. Buying more RAM is peanuts on that scale.

Brother MFC-8890DW printer
I have an opportunity to pick up a Brother MFC-8890DW printer at a fantastic price. There is a Linux driver for CUPS available at: http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/instruction_prn1c.html This is obviously not a high end unit; however, I feel I could probably get fair results out of it. It is not a color printer so it will only be used for normal b/w documents. I plan to hook it up to my router using a wireless setup on my home network. I am not worried about my Windows machines since it will obviously work; however, I want to know it this printer works as designed with FreeBSD. I doubt that the FAX function would be used at all via FreeBSD, if it is used at all. I have a dedicated FAX.

My 0.02: For printing you will most likely get IPP printing a generic PostScript driver to work with this printer, and obviously by using the provided PPD by Brother. In this case FreeBSD CUPS server will act as a client to the printer which really is it's own print server. If you get it to work with IPP you shouldn't really need a driver as such, just the appropriate filter to work (i.e. the PPD file). Scanning is probably going to be harder. All front-end sane programs support the net driver but I think that is limited to saned, the networked version of sane. I have used saned and I scan remotely with saned but the actual sane driver is running on the machine that has the device physically attached to it. Again in your case, the scanner itself provides some scanner protocol (i.e. the scanner is the scanning server sever) and it's probably not open nor compatible with the front-end sane applications. Sane as such has poor support for Brother: http://www.sane-project.org/sane-mfgs.html#Z-BROTHER But, many times these multi-function machines are OEM by others (Samsung, Xerox, etc) especially if the scanner is ADF maybe the hw is actually Canon or Fujitsu. So maybe the chipset is actually compatible with other sane drivers. On the other hand, Brother seems to be quite Linux friendly: http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/index.html From what I saw real quick it could be quite possible to get the Linux Brother network scanner driver to work on FBSD/Sane by means of Linuxator, even the network scanning: http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/instruction_scn1b.html So resuming: - It's very probable that a CUPS server (actually client in this case) will print on this network device. Probably via IPP using the provided PPD by Brother or generic Postscript I think will work for sure. - The networks scanner seems to be supported by Brother on Linux, IMO if you set-up sane at the linuxator level and you get scanimage to work inside linuxator, it will be a breeze to enable saned and scan natively from sane on FBSD. In this scenario, the native front-end sane programs (scanimage, xsane, etc.) will talk to a saned network driver daemon in Linuxator and this one in turn will talk to the networked scanner. -- Alejandro -- Jerry ā jerry+f...@seibercom.net Disclaimer: off-list followups get on-list replies or ignored.

This question recently came up on hackers, and someone posted top output from a 12GB system showing a 23GB openoffice process and 21GB of swap in use after opening a large spreadsheet file. I think there's a reasonable case for providing enough swap to cope with abnormal memory use. ___ 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: Thinkpad audio question
According to Jakub Lach jakub_l...@mailplus.pl on Wed, 09/14/11 at 13:10: See man snd_hda, you probably need to set device.hints. For example, I with T400 have something like this in device hints: hint.hdac.0.cad0.nid22.config=as=1 seq=15 hint.hdac.0.cad0.nid24.config=as=3 hint.hdac.0.cad0.nid26.config=as=1 hint.hdac.0.cad0.nid29.config=as=2 Thanks. This looks very promising. It is too bad the man page is so busy and complex... :-( I had viewed this man page before, but I hoped I would never have to deal with the details. And I haven't until now... :-) One thing that could be made more clear is the lack of how to invoke the verbose or reporting mode. The word verbose appears just three (3!) times in the man page, but there is no explicit description of how to get the driver to provide a verbose report. The word report in the EXAMPLES section refers to an HP/Compaq system housing a Realtek ALC888 HDA codec whose driver can list the default pin configuration as show. Except the man page never explains how. :-( After a great deal of back and forth, I finally discovered the hint dev.hdac.%d.pindump just above the EXAMPLES section. As soon as I put that entry in my /etc/sysctl.conf file (dev.hdac.0.pindump=1) and did a reboot, the following appeared in my dmesg(8) output: :-) Intel 82801I HDAC mem 0xfc02-0xfc023fff irq 17 at device 27.0 on pci0 High Definition Audio Controller Driver Revision: 20100226_0142 HDA Codec #0: Conexant CX20561 (Hermosa) HDA Codec #1: Conexant (Unknown) = this seems confusing...

Re: Thinkpad audio question
For maximum verbosity you can also try setting in sysctl.conf hw.snd.verbose=3 and $ cat /dev/sndstat then. Not sure if you really need it though. As for man page, that was my experience as well, and I just shamelessly copied device.hints some kind spirit provided, so I'm not exactly pinout expert either :) On a lighter note, once correct pinout will be set, you shouldn't have any more problems with CX20561, it's common and well supported chip. regards, - Jakub Lach -- View this message in context: http://freebsd.1045724.n5.nabble.com/Thinkpad-audio-question-tp4802936p4804292.html Sent from the freebsd-questions mailing list archive at Nabble.com. ___ 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

I note that there is only one AS (15, or is that 14?) and only one seq (0) which doesn't mesh well with your earlier T400 suggestion: hint.hdac.0.cad0.nid22.config=as=1 seq=15 hint.hdac.0.cad0.nid24.config=as=3 hint.hdac.0.cad0.nid26.config=as=1 hint.hdac.0.cad0.nid29.config=as=2 For example, where did 'AS'es 1, 2, 3 come from?

I do hate just copying something without knowing what the heck it means -- just the pedantic engineer in me, I reckon... :-) The snd_hda(4) man page is not very helpful in explaining what your four hints would do for my T500 problem, but I guess it is worth a try.

GTK file chooser dialog does not open in current directory
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I updated my system and now have gtk-2.24.6. Now when I open a file in, for example, scite-2.28, and then open another file the file chooser dialog opens Recently Used view whereas previously it showed directory listing for the directory in which the current file was. As you might imagine this is very annoying as I have to navigate to the same directory over and over again. How can I restore the old behavior of opening directory listing of the current/last opened directory? I found some references to a filechooser.ini on the Internet but I've been unable to find any documentation for this file. -BEGIN PGP SIGNATURE- Charset: UTF8 Note: This signature can be verified at https://www.hushtools.com/verify Version: Hush 3.0 wsBcBAEBAgAGBQJOcQqeAAoJECOi9ArdI/mVr5cH+gPHIvCzrnZOx6vR24AuJn/hfs7H SWAnz8/rinuUXWiOOvh4P43WluXP6gj/aguvyF0onQs6vhHhtm70s7xehaf15hOk6XrG 8mWKHH114ttBsTdsOv3PT+t+XJ+Tqam3ro3TNmGgpyuVCzZBA8sLUoWJMntm1ILghKKU VUhlR2QF8awUchnPiYDgMkJCkJF7Rq644aQpVCfliBqrrUXR28L6lSlBQGk3WwA8FzGN qDhLzYHZRoF9liYPePHe1nBCson7uZ34U3h+CRFsY89xkpJvemwT4OIKK6DNnsbbkEHJ 0mTcBATPChddtMqeDflRmzpHYLSe1i/fzv3/JWnVDPw= =iMhM -END PGP SIGNATURE- ___ 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: Thinkpad audio question
It was mav (Alexander Motin), he proposed those hints after I complained that sound stopped working after update. He wondered how I got sound to work in the first place, with hints I had previously. I don't think pushing those specific hints somewhere would be so beneficial, subtle hardware revision could change pin associations. (e.g. Your friend's T500?) I don't think man page is missing something, it's verbose and exhaustive, with 4 examples of hints for various purposes. (The truth is out there! heh.) The problem is, most people don't want (or don't know they need) to swap line-out and speaker functions, to split headphones and mic to separate device etc. They do not know why default pinout is not working as it should, and what they should change. They just want to have headphones and speakers working as intended :) But I'm afraid this can't be directly addressed, as possibilities of default wrong pin associations are endless. If you think otherwise you are free to submit PR as well :) best regards, - Jakub Lach PS. I suspected that If by chance my device.hints will just work, the pedantic engineer in you would be silenced somehow :P -- View this message in context: http://freebsd.1045724.n5.nabble.com/Thinkpad-audio-question-tp4802936p4805409.html Sent from the freebsd-questions mailing list archive at Nabble.com. ___ 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
