Re: [Wlug] invincible processes

OK, I found a discussion about uninterruptible sleep, and I'm sure the problem is with the usb flash device. It did the same thing in the new installation. Killing my bash shell and logging in again allowed me to unmount the device. I think I might have toasted it a few days ago when I accidentally unplugged the ps2 mouse instead of the usb. It's got a bunch of files with unintelligible names on it now, so I guess I'll try formatting it again.

I rebooted the offending drive, and everything seemed to be working fine until I plugged in my usb stick and tried to save a file to it. KWrite would not die. Copying from command line stalled, and control-c wouldn't end it. When I looked back at system messages from Friday, I found this: Jul 16 01:23:43 linux kernel: Filesystem panic (dev 08:01). Jul 16 01:23:43 linux kernel: FAT error Jul 16 01:23:43 linux kernel: File system has been set read-only Jul 16 01:23:43 linux kernel: Directory 230: bad FAT Jul 16 01:23:43 linux kernel: attempt to access beyond end of device Jul 16 01:23:43 linux kernel: 08:01: rw=0, want=131201, limit=125936 But that didn't happen when the problem occurred today.

Are they in 'D' or 'Z' state? Does "dmesg" show any kernel errors?

Thanks. The root partition (including /tmp) is only 80% full. I know I've had it higher than that in the past with no problems.

invincible processes

by Gregory Avedissian

I just had some strange stuff happen to my SuSE 8.2 installation - it's stalling when I try to copy files and run some programs. If I try to kill the process, it doesn't go away (kill -9 pid, as root), and the machine won't shut down because stuff is still running. This coincidentally happened the same day that I started to prepare a replacement hard drive, so it's not on a critical installation (in fact, it's going to be wiped), but I'd still like to know what's going on. Note that I totally disconnected this drive when I was installing on the new one, just to make sure I didn't do anything to hurt it. Any ideas on what this could be or where to look would be appreciated. Greg

Re: [Wlug] Flowchart software

Yea but open office draw doesn't have the flowchart "stencils," which means I'd have to create all the basic flowchart types myself. Xfig kinda falls under the same category. I'm really looking for something that does flowcharting out of the box and I've yet to find it. This is one of the few things that keeps me rebooting into my windows partition.

Re: [Wlug] Encrypted USB pen drive

by Chuck Haines

Yea, I ended up following the loop-aes and it work beautifully. The only problem is that the mount it root:root and can't be changed. However I was able to create a directory that is owned by my user and use that directory underneath just fine. It's actually really neat to have and was easier than I thought with Fedora Core 2.

Re: [Wlug] Encrypted USB pen drive

by Brian Waite

What about looking at /proc/scsi/scsi? You can probably parse out the Vendor/Model to decide what ID you are. That is just off the top of my head tho.
