cheap Compaq at Staples
by Bill Mills-Curran Jan. 5, 2005

Jan. 5, 2005

Staples has a low-priced machine advertised in the Globe: $199.94 for a Compaq Presario with an AMD Sempron processor. Any idea how this might work with Linux? I picked up a cheap Compaq at Walmart a year ago, and I returned it because it was such a dog. TIA, Bill

lock down /etc
by Justin Odom Dec. 31, 2004

Dec. 31, 2004

Not sure if anyone has experience with this, but I would like to lock down the /etc directory so common users cannot run through the directory and read all the files. However, programs still need to be able to read the files to work. I'm trying to do this because we have several users on our system that like to peruse the files within /etc. Anyone have any suggestions? Thanks for your help, Justin

Trouble with SATA DVD burner
by Andy Stewart Dec. 28, 2004

Dec. 28, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI all, I'm having problems with an SATA DVD burner (Plextor 712). I can't get Linux to see it. Any advice you might offer would be appreciated. Kernel 2.6.10 x86_64 The (I think) salient portion of /var/log/messages is shown below. I get this when I "modprobe sata_via": amdtux kernel: libata version 1.10 loaded. amdtux kernel: sata_via version 1.0 amdtux kernel: sata_via(0000:00:0f.0): routed to hard irq line 10 amdtux kernel: ata1: SATA max UDMA/133 cmd 0xB800 ctl 0xBC02 bmdma 0xC800 irq 20 amdtux kernel: ata2: SATA max UDMA/133 cmd 0xC000 ctl 0xC402 bmdma 0xC808 irq 20 amdtux kernel: ata1: dev 0 cfg 49:0f00 82:0000 83:0000 84:0000 85:0000 86:0000 87:0000 88:0407 amdtux kernel: ata1: dev 0 ATAPI, max UDMA/33 amdtux kernel: ata1: dev 0 configured for UDMA/33 amdtux kernel: scsi3 : sata_via amdtux kernel: ata2: no device found (phy stat 00000000) amdtux kernel: scsi4 : sata_via The chipset is VIA VT8237. The rest of the system: MB = MSI K8T Master2 FAR (2xOpteron 244) adaptec 29160 with 1 scsi disk atapi dvdrom sata plextor 712 crappy pci-based sound card ATI Radeon 7500 onboard Gb ethernet onboard usb Another data point: I booted KNOPPIX V3.6 (kernel 2.6.7), in the hope that its generally good hardware detection might make this device magically work. It notices the drive quite nicely and tries to make it available as "hde" (as seen in dmesg). However, once KNOPPIX comes up, I cannot successfully do anything with the drive. I'll burn a KNOPPIX V3.next CD and try this to see if the result changes (since that CD will probably have a more recent kernel). This gives me some hope that this device *might* work with Linux. FYI: When buying HW to build this system, I ordered the Plextor 712 ATAPI version, figuring I'd have trouble like this with SATA. The vendor shipped me the SATA drive at the cheaper ATAPI price...go figure.

I believe it was 2.6.8+ that changed the way cd burning (SCSI generic or ATAPI SG_IO) support worked. This was done to fix some security issues where a user could e.g. reflash the firmware on your drives, rendering them toasters. There is now some SCSI command filtering done to prevent such things. Fedora has pretty much abandoned ide-scsi and has switched instead to the SG_IO API directly on the underlying ATAPI device. This allows applications to send SCSI Generic commands by using the ATAPI device instead of the SG device which required the ide-scsi hack for ATAPI devices. I know this change broke a lot of things, mainly people's expectations on which device to use with cdrecord et al. It is now as simple as: cdrecord dev=/dev/hdc or similar.

Proliant 1600 for sale
by Mike Leo Dec. 28, 2004

Dec. 28, 2004

I go back and forth on this, but I have a Compaq Proliant 1600, dual 450 (or 500, i forget), with 6 18gig drives, plus an F1 full of 18gig drives, plus some spares. I can also put in a DLT drive. It runs fine, but is loud. I go back and forth with wanting to sell it 'cause I didn't think anyone would be interested. But is anyone? $600 for the whole shabang. I can get more specific specs once I get home. I can bring it to a lug meeting, or can arrange shipping. Let me know... Mike __________________________________ Do you Yahoo!?

Sun's x86 Strategy
by Gary Hanley Dec. 23, 2004

Dec. 23, 2004

Hello all. I came across this article today that some might find interesting. It touches on Sun's disadvantage with regard to Solaris development costs compared to Linux and how it plans to deal with that, as well as the probable demise of UltraSparc. http://www.techuser.net/sunx86.html -- Gary
