Re: FreeBSD compatible mini-itx board

I've had VIA boards but flacky disk controller and other problems have made me look for something else. So, going all Intel, I hope there will be no hardware problems. I'm looking at The Intel D945GSEJT with an Atom N270 processor and the following specs: Mobile Intel 945GSE Express Chipset Intel 82945GSE Express Chipset Graphics/Memory Controller Hub Intel 82801GBM I/O Controller Hub (ICH7-M) Intel GMA950 RealTek 8111DL Gigabit Ethernet Controller Does FBSD support this? I don't care about graphics basic VGA is enough as this will be a headless server. But I do care that the disk controller is fully supported as well as the NIC. Any suggestions of alternative boards? AFAIK the N270 is single core 32bit, a dual core and/or 64bit alternative would be interesting. Also: The Intel manual mentions: Support for DDR2 533 MHz SO-DIMMs (DDR2 800 MHz and DDR2 667 MHz validated to run at 533 MHz only) Will faster RAM result in a less stable system? And what is Serial Presence Detect RAM? I've never seen this advertised. Lots of questions, I know... Thanks, Erik ___ I'd recommend the below instead, DDR2 is deprecated. http://www.intel.com/products/desktop/motherboards/db-D525MW/D525MW-overview.htm I've had good results with these. These can do 8GB on amd64 (though the aforementioned page only states 4GB) with 2x4GB DDR3 1066 SODIMMs. AHCI GbE work fine. The D525MW is dualcore+HT, there's also the 425KT single core+HT variant. The latter doesn't have GbE...not worth it IMHO. ___ 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 may need to pinch pennies if I have to finance my next servers out of pocket. Stupid idea, I know, but I really want to know if there's a reason to skimp. Specific models that you're considering would be good. For WD, if you're referring to the WD's GreenPower (non-RAID Ed), there are 2 gotchas 1) no support for TLER any longer - this IMHO is a deal breaker for RAID 2) ridiculously low sleep times (6s) to maximize power savings - in a server, this would cause extreme load cycles, however this setting can be set to less extreme numbers using wdidle. The main technical criterion for any HDDs to be used in a raid IMO should be TLER support IMO. Speed/capacity would be secondary concerns. regards, TJ ___ 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: Wester Digital 'deep recovery cycle' and gstripe?

My concern, is the disks are 'consumer grade' disks. Western Digital mention not to use them with a raid controller as they have a potential, 'deep recovery cycle', which an last up to 2 minutes. This would theoretically result in them being dropped from the array. Despite this, I've heard successful uses of these disks via gmirror. (Granted, not the same as gstripe). Again, in theory, if one disk enters a 'deep recovery cycle' and is dropped from the array, and during that time another disks does the same the array is toast, right? Umm...what are the odds of this occurring? War stories? (The more I type this out, the more it's starting to sound like a bad idea.) Thoughts, ideas? -Modulok- google for WDTLER.EXE. I've had good results setting the recovery time to 7 seconds on the Caviar Greens Blacks. FWIH, it only works up for WD drives up to 1TB.

Re: hdd voltage
2009/11/18 Dánielisz László laszlo_daniel...@yahoo.com: Hello, My computer get starts to reboot all the time I do a higher hdd use (like: fsck, copying more GB of data). I was sure that my power supply its not enough so I changed it (300W-450W), now it does the same. I'm looking for a tool to measure the exactly power consumiton (voltage and amper) of my hdd, cpu and ram on FreeBSD. Do you have any idea? Thank you! László You don't mention details on mobo/ram, but if you have 4gb ram on amd64, you might want to try reducing ram to =4gb. I had one mobo (Intel DG965RYCK) that was exhibited odd behaviour with more than 4gb ram installed. Simple file copies (on ZFS), buildworlds etc caused various panics or outright hangs (!). Usually this would be a clear indication of faulty RAM, but it passed all memtests. Changed everything (ram, psu, hdd, cables, RMA'd the mobo), no difference. Turned out to be a BIOS bug, some linux list had discussions on the same bug. ___ 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

What are some good practices for securing this SSH server. Is using a stored key safer than a password in this instance? I have no experience with port-knocking, but I'd appreciate some tips or suggested beginning references... I welcome any and all advice. Note: I do require X11 forwarding (not sure whether that's relevant information) I have password authentication disabled on my public SSH server. You can accomplish this by setting: ChallengeResponseAuthentication no in /etc/ssh/sshd_config. See sshd_config(5) for more information. This allows you to enforce the use of stronger authentication methods (e.g. public key). Keep in mind, however, that this setup will only be secure if you keep your alternate credentials (e.g. private key) secure as well. If for some reason you would prefer to use password authentication, I would recommend that you look into automatic brute force detection. There are a number of utilities in ports available for this purpose, including security/sshguard and security/denyhosts. I'd recommend changing the listening port to something other than 22. This reduces brute-forcing attempts by script-kiddie tools. Public key authentication should be mandatory, in addition to having a passphrase to your private key. Make sure your laptop is secure. Stay on top of the security lists for openssh vulnerabilities. ___ 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: CPU/motherboard recommendations

The ideal motherboard would be small on bells and whistles (onboard NIC, video, and RAID are optional (even undesirable) though a decent sound chip would be good) and big on reliability, expandability (this machine might end up with 8gbytes memory and many storage devices), and good layout.
