data exchangers? I have much more respect for government workers,
crypto experts, mathematicans now than ever.

2012/8/29-11/7 [Computer/SW/Security] UID:54467 Activity:nil | 8/29 There was once a CSUA web page which runs an SSH client for logging
on to soda. Does that page still exist? Can someone remind me of the
URL please? Thx.
\_ what do you mean? instruction on how to ssh into soda?
\_ No I think he means the ssh applet, which, iirc, was an applet
that implemented an ssh v1 client. I think this page went away

2012/5/8-6/4 [Computer/SW/Unix] UID:54383 Activity:nil | 5/8 Hello everyone! This is Josh Hawn, CSUA Tech VP for Spring 2012.
About 2 weeks ago, someone brought to my attention that our script
to periodically merge /etc/motd.public into /etc/motd wasn't
running. When I looked into it, the cron daemon was running, but
there hadn't been any root activity in the log since April 7th. I
looked into it for a while, but got lost in other things I was

Hall server room reorganization (we're being moved to a neighboring
server cabinet). Downtime will hopefully be minimal. --jordan
\_ Thanks for all your work keeping the machines running! It's
been awesome having soda actually working again.
\_ Update: this is tentatively scheduled for Saturday afternoon.

four month old daughter to SIDS. What is the correct response here?

2012/1/4-2/6 [Computer/HW/Drives] UID:54281 Activity:nil | 1/4 I want to test how my servers behave during a disk failure and
a RAID reconstruction so I want to simulate a hardware failure.
How can I do this in Linux without having to physically pull
a drive? These disks are behind a RAID card and run Linux. -ausman
\_ According to the Linux RAID wiki, you might be able to use mdadm
to do this with something like the following:

another long nightmare of poor hardware reliability!

2011/2/18-4/20 [Computer/SW/Unix] UID:54044 Activity:nil | 2/18 Why does the system seem so sluggish lately?
\_ Slow NFS is basically always the answer. --toulouse
\_ Any truth to the rumor that soda will be decommissioned this summer?
\_ Absolutely none. Soda might go down temporarily while disks are
reorganized and stuff so soda doesn't suffer from such shitty
performance nearly as much, but no, we've gotta maintain NFS and

2009/7/28-8/6 [Computer/HW/Drives] UID:53216 Activity:nil | 7/28 Does it make sense to defragment disks on VMWare? My 80GB disk
on VMWare isn't really using 80GB, it just uses what it needs.
Will defragment do anything to it?
\_ If you want to speed up disk operation in your VM, it's best to
defragment the disks in your VM, then defragment the disk on your
host machine where the VM files are.

2009/5/2-6 [Computer/HW/Laptop, Computer/HW/Drives] UID:52933 Activity:kinda low | 5/2 I have a 1Gbps switch. It is connected to a SANS RAID-1 with
two WD Green 1T that takes 1Gbps connection, as well as a laptop
that is also 1Gbps. Online benchmarks show *sustained* transfer
rate of about 1/2 of 1Gbps with the WD Green... cool!!! But
in practice, I'm only getting 68Mbps (read SANS->PC file transfer),
far below what I expected. The switch says both devices are using

2008/12/10-16 [Computer/HW/CPU, Computer/HW/Drives] UID:52220 Activity:moderate | 12/9 Another idea for the CSUA that lets you spend money and maybe get some
cool toys. Instead of buying a beefy server (like say, a massive server
with 20 386DX processors), buy a few cheap machines (like the ones
mentioned below) that have good disks and work on failover / load
balancing. A netscaler or other piece of hardware is complete overkill,
but maybe hacking an OpenBSD box could do the trick. The idea is that

might be able to hit Intel up for donated/partially donated (reduced
price) Core i7 Xeons when they come out? Who would be a good person
to contact about something like that? We're of course willing to put
out for them - perhaps we'll tattoo an Intel logo on toulouse if that's
what they want :-p -- steven

I'm wondering what the best alternatives for virtualization are, and
how best to cut my teeth on messing with non-linux platforms (or I
guess interesting stuff on Linux would work too). Right now I've got
FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am
somewhat at a loss as to how to use it. (More details: bridged

what's a good buy?
\_ I did a bunch of research and ended up with Dlink DNS-321. It
is newer than DNS-323 with less problems. It doesn't have as
much buffer as DNS-323, but if you're transfer files bigger
than 32 megs, the sustained rate for both are equivalent. I
