If anyone is interested in a talk on SSDs, chime in. I can present my experiences with these devices. I've evaluated the performance of several vendors' products, ranging from the poor to the exemplary. I can talk about the modifications made in the block layer to accommodate for these devices, and the current implementation of the block discard support (which maps to ATA TRIM, which is important for device lognevity and performance) and how that is wired up to file systems such as ext4. Cheers, Jeff

vmbuilder - Ubuntu Lucid?
by John Stoffel 01 Mar '10

01 Mar '10

Hi, Anyone else using vmbuilder with Ubuntu's 10.x Lucid Lynx (Alpha3, I know) and cursing the change in options that just happened recently? I've been playing around building VMs (based on Karmic) and tossing them away since it was so quick. Now that I've upgrade to a newer version of Lucid, it's all busted. Sigh... This would be a good talk too, about building and using VMs. Here's the script I whipped up to help automate things, which is now busted. Sigh... I realize I need to just look in the docs, but they a) suck and b) aren't easily found. Nor is any list of changes in the options listed nicely either. Grrr!!!!

I've noticed that not too many people have putting in meeting topic requests, so I thought that if anyone's interested I'd volunteer to throw together some slides on BtrFS. For those of you who haven't heard of it, BtrFS is the next generation linux filesystem. Though still in heavy development, it was included in the mainstream kernel last year. It promises to scale to filesystems well beyond what any of the current offerings can handle (including ext4), as well as offering far greater flexibility and better data security for data admins.

[OT]Seeing SCSI devices in Solaris
by Chuck Noyes 14 Feb '10

14 Feb '10

Hi All, This may a bit [OT], but ... At work we have several Sparc servers running Solaris 10u8 that are connected to storage arrays via fiber cables and switches. Some of these hosts can have thousands of connections and can take hours to boot! Does anyone know a way to view the scsi connections in Solaris? In RedHat, I can do a cat /proc/scsi/scsi and see the connections. How can I do this in Solaris? devfsadm doesn't seem to give me what I want, and Google doesn't provide too much help. TIA, -Chuck

Upcoming meetting reminder
by Andy Stewart 06 Feb '10

06 Feb '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, I've just updated the website...sorry that I let it get so out of date. We have a meeting coming up on Thursday, February 11th in that meeting room next to the Morgan Hall dining center. It is very close to the former Access Grid room where we used to meet. If anybody is interested in leading the discussion or giving a presentation, please let me know, or just bring it to the meeting. If I know in advance, I'll announce it on the website - this often attracts more people to the meeting. Our last meeting was rather lightly attended, perhaps because I didn't get the reminder out in enough time. I pulled together a talk about how I used libHaru to generate PDF output from a program that I wrote. I could bring in another program (Perl script) that I wrote to get data out of a ham radio related piece of test gear. It is the very first native Linux program in the world to talk to this device. I know because I asked for (and received!!!) a previously unpublished specification from the vendor. Sweet! I will be releasing this program under the GPL v3 shortly. I'm looking forward to seeing lots of people at the next meeting. Of course, we'll go out after the meeting for pizza and socializing.

201 CMR 17 - "Standards for the protection of personal information of residents of the Commonwealth" - takes effect March 1
by Ryan Pugatch 01 Feb '10

Hello all, Just wanted to remind everyone that 201 CMR 17 takes effect March 1! If you're not familiar with this regulation, it specifies policies, procedures, and security requirements that are needed if you store a minimum of first initial and last name in conjunction with a social security number, drivers license/id number, financial account number (credit, debit, bank account number), or an access code or PIN/password that would allow access to a bank account. This doesn't just apply to companies that accept credit card payments. Think of it from an HR point of view as well.

GPS
by Mike Leo 30 Jan '10

30 Jan '10

I have a great little Lenovo netbook and I haven't found a good use for the expresscard 34 slot I've been researching GPS devices but can't find an ExpressCard 34 style GPS device. I could get a normal GPS device with a screen and junk, but that would defeat the purpose of my search. Does anyone have experience with using a laptop with a GPS device? FYI: I already have maxed out the ram and have a 150gig hard drive, plus a webcam and bluetooth...if anyone can think of a better use of the Expresscard, I'd like to hear that, too! Ciao

Problem with wireless access point(?)
by Andy Stewart 31 Dec '09

31 Dec '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi gang, I just purchased a Linksys WRT54GL wireless access point. Currently, it is running the stock firmware (upgraded to the latest version). I may put Linux on it sometime in the near future. While I can get connected to it with my Linux laptop, I notice that file transfers start at a screamingly fast rate, and within a minute or two, drop to barely a trickle. When I used an entirely hard wired connection, I have no such problem. Has anybody else noticed this with the Linksys WRT54GL? If so, will the Linux software solve this problem? I don't believe that the problem lies with the wireless hardware/software in my laptop since I have used it on other wireless access points without problems.

Re: [Wlug] Wlug Digest, Vol 74, Issue 14
by Karl Lind 31 Dec '09

Karl had posted an answer about the Linksys (under the subject line "Re: [Wlug] Wlug Digest, Vol 74, Issue 13") One comment in there I found very interesting: > Now this is going to blow your mind, but if there is ANY difference in the Workgroup name between the router and the computers, it causes the router to "restrict" bandwidth. Does this only apply to various forms of filesharing, or to all wireless traffic through the WRT54GL? I (and my housemates) are not doing big downloads, and not using Samba. Maybe one of the Windows PCs here might occasionally d/l a movie. But in experimenting with wireless here, using one or other of my Debian PCs, Tomato on the Linksys, I also thought the wireless worked rather slow, even though we have a +20MBps connection. Mostly what I was doing was browsing. Do all computers using wireless here have to belong to the same Workgroup, no matter what kind of internet traffic they're doing? If I do need a Workgroup name for the router, how do I do that? Thanks, Liz J Hi Liz What's humorous is the difference between the words "Default" and "default". Most routers may allow you to log on, but subsequent packets of data may not verify correctly, hence the speed loss. As noted by Andy, wireless always defaults to the slowest speed connected. (I seem to have a lot of neighbors that try to break in to my network and when they do at G, B or even A speed the router slows and that tells me that somethings up and I can do something about it.)

FYI WRT54GL Linksys released the *WRT54GL* in 2005 to support third-party firmware based on Linux <http://en.wikipedia.org/wiki/Linux_kernel>, after the original WRT54G line was switched from Linux to VxWorks<http://en.wikipedia.org/wiki/VxWorks>, starting with version 5. The WRT54GL is technically a reissue of the version 4 WRT54G. Cisco was sued by the FSF<http://en.wikipedia.org/wiki/FSF_vs._Cisco>for copyright infringement, but the case was settled. [6]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#cite_note-GPLInfringemen…> Version [image: ↓] <http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> CPU <http://en.wikipedia.org/wiki/Central_processing_unit> speed [image: ↓]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> RAM <http://en.wikipedia.org/wiki/RAM> [image: ↓]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> Flash memory <http://en.wikipedia.org/wiki/Flash_memory> [image: ↓]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> S/N <http://en.wikipedia.org/wiki/Serial_number> Prefix [image: ↓]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> Notes [image: ↓] <http://en.wikipedia.org/wiki/Linksys_WRT54G_series#> 1.0 200 MHz 16 MB 4 MB CL7A New model line, released after the version 5 WRT54G, which returns to a Linux-based OS as opposed to the VxWorks firmware. SpeedBooster <http://en.wikipedia.org/wiki/SpeedBooster> is not enabled in stock firmware, however third-party firmware will enable the feature. The hardware is essentially the same as the WRT54G version 4.0. One alteration is that the internal numbering scheme of the 4-port switch changed in this model, from 1 2 3 4, to 3 2 1 0. 1.1 200 MHz 16 MB 4 MB CL7B CL7C As of August, 2009, this version was shipping with firmware revision 4.30.11. This pre-loaded firmware allows the user to upload a 4MB firmware image, whereas the pre-loaded firmware on version 1.0 limited the image to 3MB. Firmware version 4.30.13 is now available for both hardware versions. Fully supported by Tomato <http://en.wikipedia.org/wiki/Tomato_Firmware>, Sveasoft<http://en.wikipedia.org/wiki/Sveasoft>, OpenWrt <http://en.wikipedia.org/wiki/OpenWrt>, and DD-WRT<http://en.wikipedia.org/wiki/DD-WRT> . Hardware versions affect firmware compatibility As of January 2006, most third-party firmware is no longer compatible with version 5 of both the WRT54G and the WRT54GS. The amount of flash memory in the version 5 devices has been reduced to 2 MB, too small for current Linux-based third-party firmware. (See table above for information on identifying the version based on the serial number printed on the bottom of the unit, and on the outside of the shrink-wrapped retail box.) Some users have succeeded in flashing and running a stripped down but fully functional version of DD-WRT called 'micro' on a version 5 WRT54G.[21]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#cite_note-20> [22] <http://en.wikipedia.org/wiki/Linksys_WRT54G_series#cite_note-21> An easier method not requiring any disassembly of the device has since been devised for flashing v5-v8 to DD-WRT.[23]<http://en.wikipedia.org/wiki/Linksys_WRT54G_series#cite_note-22> [24] <http://en.wikipedia.org/wiki/Linksys_WRT54G_series#cite_note-23> To support third-party firmware, Linksys has re-released the WRT54G v4, under the new model name *WRT54GL* (the 'L' in this name allegedly stands for 'Linux'). It is also possible to replace the 2MB flash chip in the WRT54G with a 4MB flash chip. The Macronix International 29LV320BTC-90 is a suitable part although others may work as well. The user must first install a JTAG header <http://en.wikipedia.org/wiki/JTAG_header> and use a JTAG cable to backup the firmware,then replace the chip and restore the firmware with the JTAG cable. After testing for proper functionality of the modified unit,3rd party firmware can be flashed using the JTAG cable and a suitable image file. Now this is going to blow your mind, but if there is ANY difference in the Workgroup name between the router and the computers, it causes the router to "restrict" bandwidth. Crazy, but true. Also make sure your hardware all matches. (802,11B, G, N) Have you tried disabling DHT and NOT forwarding UDP? (In case it's a memory issue) Just my two cents....

Mounting Windows Shares on Solaris
by Chuck Noyes 15 Dec '09

15 Dec '09

Hi All, Maybe a bit [OT], but I've got a Solaris 10u8 host, and I'd like to be able to mount a Windows share on the Solaris box. I don't think Solaris supports the smbfs or cifs file systems (at least I can't find any evidence of it). So a command like: "mount -F smbfs //windows-host/share /mnt" won't work. Has anyone done this? I've installed all the samba executables in /usr/bin and in /usr/sbin on the Solaris box, so there is samba support in Solaris, but I can't seem to mount the Windows share. TIA, -Chuck
