Flaky disks or controller?
by Andy Stewart June 10, 2003

June 10, 2003

HI Everybody, Having recently rebuilt my "good" computer, I'm now seeing a bunch of disk I/O errors in my system log. I have 3 SCSI disks connected to a Symbios controller using the sym53c8xx module and a 2.4.20 kernel. At first, I suspected an individual drive, as it is nearly 4 years old, and all of the errors were there. I have since physically removed that drive, and now the other drives are logging errors rather sporatically. Typically, I see an error message from reiserfs about how it couldn't write to the drive, and a disk I/O error in the log. The system is then wedged and requires a reboot. With the problem showing up on all 3 SCSI drives, I'm now suspicious of the (used) controller which I received as a "present" from a guy at work. If it should be the controller, do you folks have recommendations about reasonably priced SCSI controllers? I have 6 SCSI devices in my system and I need 68-pin as well as 50-pin capabilities. One of my disks is U160, and I think the others are slower, but with disks always getting faster, I'd probably want a U160 controller. I don't think I want to pay the premium for a U320 controller. Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Linux and wireless 802.11b
by Chuck Noyes June 7, 2003

June 7, 2003

I haven't had any luck getting a Netgear MA401 802.11b PCMCIA card working. I'm using RH 7.3 (2.4.18 kernel). I rebuilt the kernel to turn on support for the card, but I can't get a connection to my access point (a Netgear WG602). The kernel boots and tries to start the eth0 interface, which doesn't exist, since there's no CAT5 cable pluggeg into the ethernet port. The output of ifconfig shows the only interface that's up is the loopback (lo) interface. I have an HP Pavilion zt1180 laptop. Is there anything else I need to do? Thanks, Chuck -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

Old drive - new machine?
by Richard Goodman June 3, 2003

June 3, 2003

I have a RedHat 7.3 server that is sick. It would appear that there are all kinds of hard disk errors but I don't think its the hard drive because its done it with two new hard drives. I'm guessing its the on-motherboard disk controller. It will boot up okay, but after a (steadily decreasing) amount of time the errors begin again and the hard drive light stays on. The question is: the motherboard is an old Socket-7 AT Epox which I can't replace exactly -- what are the issues involved with swapping the drive (which I believe is okay) into a new machine with a different motherboard, without reloading RH 7.3 or my data?

NEW Pioneer DVD-RW A05 for sale
by Skip Gaede June 1, 2003

June 1, 2003

Folks, Ever made a mistake? I did. I purchased a new DVD-RW drive to replace the unit I thought was defective. After the unit arrived (Thursday) I subsequently trace the problem to an intermittent IDE cable. I'd like to sell the new one if anyone's in the market. The A05 is a 4X drive, and I paid $225.00. for it. I'd be happy to sell it for a reduced price of $200.00 if anyone's interested. Thanks, Skip

How reliable is the ls -l listing. In other words is it possible to modify a file and leave false timestamp on it. Thanks, -- Michael Long <mlong(a)datalong.com>

http load generators
by twg3＠attbi.com May 20, 2003

May 20, 2003

Does anyone have any recommendations of open source tools for generating very high volume http traffic simulating large numbers of clients form multiple IP addresses? I did a search on sourceforge and most of the projects have not released any new code in 18 months or more - so not sure of status on most of them. I need to test an application that uses HTTP as its transport layer (but not HTML) so open source tools would allow the customizations I need, with out haveing to write everything from scratch.
