So as networks expand, you get more and more of those pesky cat5e/cat6/serial/etc cables. Keeping track of which port on what goes to what is helpful, but when you need to do work it is very, very nice to know which cable is what on the switch/patch panel. So far it seems like there are three...

So for those of you who manage multiple environment clusters with different tasks, how do you do it? Currently I use a script that just ssh's to every server and runs a command, ie: ssh_all.sh "rpm -U /tmp/newpackage-2.0.rpm" This is less than ideal since it isn't threaded and can't really...

So my workstation has been plenty fine for a long time. Incredibly stable, I've had multiple 30+ day uptimes, usually having to shutdown because I'm going on vacation and not because the system has issuse. I've lost power to the machine maybe twice in the past year and nothing ever directly...

Alright a friend of mine needs a website to host a college club, which will consist of meeting dates/info and club-related information in general. They're also going to take photos of the various protests they do, so a photo gallery with some level of integration is desired. These people are...

This is sort of weird, last night I noticed on my test array that I was getting 210mb/s writes and 170mb/s reads when I set it up with raid0. Now I have it setup as a rebuilt raid5 (8 hour rebuild weaksauce) and I'm getting about 130mb/s writes, and 110-115mb/s reads. The CPU is absolutely...

I decided to make a new thread for this instead of posting in the other thread. Dell is currently selling a 5 Pack of Intel Pro/1000 PT Dual port (PCI-E 4x *NOTE* THIS WILL NOT FIT IN A 1x SLOT!) server cards for that price, but there is sort of a catch. Their website makes an explicit claim...

I've got my two systems, each with 4 gigabit ports, 2 from skge/forcedeth and 2 from the Intel Pro/1000 PT Dual Port Server card (bonded into two different virtual nics using roundrobin). Linux 2.6.18. The Intel nic's are connected to each other using a crossover, so they are directly connected...

So I got my new test file server running, and initial reports are kinda, weird. In a single nic configuration using master/slave, I'm getting about 660mbit/s speeds. Not bad, not perfect, my workstation is only a single gigabit link on the a8n32 so I can't really say whos fault this is. CPU...

Alright, in my effort to do some heavy duty analysis on building cheap storage pools, I wanted to get some real cost analysis on all my different options. The first phase of this was to get some pretty pictures of different raid levels combined with different drives and being able to see exactly...

I wasn't sure if I should have placed this in the motherboards section or in the networking section, but I'm looking for a motherboard that has dual gbit nics that both support jumbo frames (ideally 9000 or higher). Ideally the price would be ~$100, have strong linux/bsd support, and has 4+ SATA...

Ok so in our LUG we have a lot of cheap hardware. As we all know, cheap hardware tends to fail a lot. So for the past while I've been tinkering a lot with clustering, trying to make a very high availability solution. So far, I've come to discover a lot of software that can be glued together to...

I'm looking for something very secure to replace my gentoo hardened selinux machine that currently runs some basic services (rsync+non transparent squid). I'm toying with OpenBSD 3.9 at the moment, though I'm running into a few issues. Primarily, how hard is it to update the base system? I...

I'm a little bored and want to pick up ap project before school picks up and I can't do anything fun anymore. Is there currently anything out there that can take a range of IP addresses, and quickly map the network (routers and such) in some sort of distributed fashion. Optional features might...

Alright, my boss has tasked me and the other tech with building a high performance storage solution. The only specifications for the system are: -full redundancy -hot swap -high-bandwidth interconnect desirable (My assumption is he wants 10-20gbit capability incase we ever go infiniband on...

Thinkgeek supposedly has production samples and says it'll be available mid-September. http://www.thinkgeek.com/computing/input/88ee/

So I'm looking at a 360, around here I've got Gamestop, Best Buy, Circuit City, and maybe a few other shops (southern california). I'm reading threads about people losing their 360, and I'm worried that mine will die after a while (it is a pretty big investment). How do the different warranties...

Theres been a lot of good stuff so far here at Defcon. Thought I would keep the [h] people informed of the latest tricks and traps. First and foremost, the coolest thing I've seen so far at defcon would have to be an advanced NTFS filesystem called FragFS or something like that, basically what...

I'm a little curious as I'm delving into high-availability clustering, what kind of hardware/clustering HardOCP uses? I'd be very interested in how bottlenecks were overcome with running such a big site. Thanks! -hoka

http://www.defcon.org/html/defcon-14/dc-14-schedule.html Anyone else going this year? I'll be there again :cool:

So I just built a new mini system of the one in my sig, specs are as follows: Antec P180 a8n32sli Seasonic S12 600w evga 7900gt corsair xms 3200-2048c2 (2x1gb sticks) amd64 4000+ (single core) Basically, I turn on the system, the fans start turning, but nothing comes up on the screen. I...

Currently I've got the machine in my sig, only one drive is there for windows and the Areca drivers arn't even installed since I use the areca array exclusively for linux. I want to build a fairly identical machine, but move to a single core and the ideal situation is to not have to reformat...

My first piece of Cisco equipment, a 24port switch 2924C-XL... should be 1 unit. I'm looking forward to the rewiring and the managing of something :D For $150 how could I really be let down. Now all I need is for it to show up and to get a cisco router! *dance*

Well, I had so many great times with my Areca 1220 that I decided to spring on a 1110 at work when we lost a software raid array for the third time. The weird thing is that it only picks up the drives sometimes? And its degraded itself two times already. I'm hoping an actual install on it and...

So my roommate started to build a file server but software raid sucks the big one for support on Linux (not the first time either I guess). Anyways, I'm looking for a 4-8 port real hardware raid controller, works on PCI 32bit 33mhz (standard PCI), and has linux support. Cheaper the better, do...

Well, I went to the dark side, bought a new drive and downloaded XP64 (free, thank you MSDNAA!). The first thing I decide to do is install Steam and get some CS:S on, but that means downloading it at a whopping 3.6gb if I saw those numbers correctly. Now that wouldn't be so bad if it was...

So I was asked today to make it so that when you log into a system, your profile is for that machine only. Currently we're running Samba 3.0.14-r2 as our controller, but I'm not sure what really to Google for. Any ideas?

Well, I've decided to bite the bullet and switch from reiserfs to XFS. I needed full uptime from it, and it croaked horribly this morning. So I've spent my morning so far trying to get LiveCDs to work, and eventually discovered that there was enough life left in reiser to copy over critical...

I went a little crazy on craigslist. They're P3 800mhz with 128 or 256mb of ram. I'm hoping to use it for database clustering, apache test clustering, linux virtual server, and hopefully some folding inbetween :D using my kvm switch to work between them / my multimedia box, and its own switch...

I've got a 533fsb 2.26 p4 cpu cooler that is incredibly loud, and i'd like to make it quieter. Theres a 80mm fan basically right next to where the cpu cooler for system cooling and the system doesn't ever really see a heavy load. Would it be safe to underclock the system a bit and run it without...

A Dell Inspiron 1300 with 512mb ram, 1.7ghz pentium m, dvdrw, and all the other typical goodies. I really needed a cheap machine to lug around to class. No need for gaming on it but I'm installing Linux the second its in my hands :D Is it still pretty easy to upgrade ram on the Dells? That...

I'm stuck in sort of a pickle here. I've got 4 solid drives in raid 5. I just got one more in and I'm ordering the other 3 shortly for a total of 8 on my Areca 1220. Except that you can't convert from raid5->raid6 (downgrade only it seems). This leaves me with either expanding 3 more drives...

So I've been working on building a system that doubles both as a workstation and as a home theatre. Basically one system runs a monitor and a TV completely separately with the ability for the workstation to run things on the TV. So far I'm using Kubuntu as a base running two completely separate...

So I picked up 4 panaflos for my stacker 830 a while back, and they were a little on the loud side at night for sleeping, so I decided to pick up a fan controller (Vantec 3.5" thingymajig, PWM I guess). So now when the setting is at the minimum (7v I think?), the panaflos sound just like they...

Alright, I've got both my SATA cages in my Stacker 830, and with 2 cd/dvd devices, that only leaves one 5.25" slot. But the problem is I have 6 IDE hd's that I'd still like to use a few of (who wouldn't mind an extra 700gb?). Is there some way to have an external cage with the standard IDE plug...

So I've got an Areca 1220 hooked up to the 2nd pci-e 16x slot of an a8n32 with 4 WD 320GB RE's in a hot swap cage from Newegg (Chieftec or something). I'm running Gentoo 64bit (reiser3) using gentoo-sources with the areca code hijacked from the matching -mm sources, and for the first day or so...

So I got my retail Opteron 175 and everything looks fine except that the bar you flip back and forth (to loosen/tighten) doesn't have a latch like it does in the sample "video" / pictures. When I put the heatsink on it went alright, I pulled it back but it seems like it doesn't want to get...

Was looking around to find a local shop to get my stacker at, and I found out that Micro Center had 2 in stock and it's only $223.99, ran and picked one up an hour later. Appears to be the cheapest price around (and they are listed on Cooler Masters site as an official dealer)...

So on Monday I show up to work and theres a seemingly simple task: replace a bad power supply from a rack mount server we had purchased entirely from Monarch. The replacement power supply was there, so all we had to do was yank it and plug it in. Upon opening the case and making sure everything...

Building a new workstation for mostly software development, some photoshop things, some video editing, otherwise lots of multitasking (python/lots of firefox/office documents). Suggestions/comments welcome. Stacker 830/810 with Panaflo's for cooling wherever applicable Seasonic S12 600w...
