421  Linux Stuff / Kernel / Re: Clock drift? on: August 06, 2009, 04:38:02 PM
If hardware clocks were accurate no-one would have written ntp.
30ppm isn't much.  Far better than my typing skills.
422  General Category / General Discussion / Re: How to do fsck on the root file system? on: August 06, 2009, 03:02:32 AM
The other way to do it, which occurred to me later and is what I do for the CompactFlash card on my Asus wl500g, is to shut the system down, take out the card and fsck it on another Linux system.

Whoopee do!  My shipping status has changed to "Shipped via FedEx International" this evening!  Ordered 27 June (well - it was for me, but GT's date has the 26th, and they shipped it in the morning).

You're both missing the point.  Use emacs  Smiley.

But, if you are setting the hardware clock it presumably has one.  Why would you want to set it everytime?  Why not read from it to get the time first, rather than hardwire January 2009?
The time to set it is on shutdown. And every hour with a cron job (to cover crashes, which don't have a shutdown).

The "usual" thing to do is to give forcefsck as an additonal boot parameter (or create a /forcefsck file before rebooting). At least it s for RedHat and Mandriva. Have a look in yor /etc/.rc.sysinit file.  It will then fsck all disk mounted at boot time, including the root partition (but if it changes anything there it will reboot immediately afterwards).

You may not want to run that as is anyway.  It's going to set the system time to a fixed time (18:00, Jan 26, 2009), and then set the hardware clock based on that.  Seems a very strange thing for a boot script to be doing.

Your problem is not unique.
This just showed up on slashdot (haven't read any of it beyond the intro, yet...)

There is this Entropy Gathering Daemon, which might enable you to gather sufficient randomness?

Perhaps there's hope for my June 26 order seeing progress shortly, then.

On the subject of response to mails I reported yesterday that their website had no horizontal scroll bar in Firefox, but did in IE.  A bit annoying when the LOGIN button is on the R/h side (or, in my case, underneath the bezel  Sad ).  Pointed out that it was caused by "overflow: -moz-scrollbars-vertical; " in the style sheet.  I had a reply back today - and it's fixed!
431  Linux Stuff / Kernel / Re: Problem with /dev/random ? on: July 31, 2009, 03:28:16 PM
Now, the next questions are why is it empty, and how can I change that?..
You could try using /dev/urandom, which won't block (but won't be "as random" if not being fed enough randomness.
432  General Category / General Discussion / Re: fsck / never in fstab? on: July 29, 2009, 04:42:12 PM
They're all either kernel-based (sysfs, proc), or built-from-scratch-at-boot (tmpfs).
Expect /, which is rootfs.  But I think that is built at boot time too? (I'm sure someone will correct me if wrong).
So there's no point fsck'ing them as they all only just been created.
433  Linux Stuff / General Linux questions / Re: Memory usage tip on: July 25, 2009, 05:07:01 PM
If You get nervous seeing plug's mem too extensively used try this:

sync
echo 3 > /proc/sys/vm/drop_caches
You may need to do this twice (from experience on x86_64 systems).    Also - it doesn't really "free" much memory. It can free up some slabinfo tablespace , but most of what it releases is only in use because nothing else needs it.  So if the memory usage in top frightens you, just remember that most of the space in "buffers" is free-to-be-used-when-needed anyway.
434  General Category / Application ideas and development Q/A / Re: Has Anyone Built A Live CD for Development? on: July 24, 2009, 10:14:53 AM
I'm having trouble with the file. I ran an md5sum on it and got:
f5cf081d4361ea32230449226efebec6  ubuntu-8.04.2-desktop-i386-sheevaplug.iso
Hmmmm....I get:
3121280126852919f4372aab24e754ba  ubuntu-8.04.2-desktop-i386-sheevaplug.iso
-rw-r--r-- 1 me... mine.. 735832064 Jul 21 22:12 ubuntu-8.04.2-desktop-i386-sheevaplug.iso

When I check the actual iso, I find that three files don't match the internal checksums. Two of them are manifest files and should not matter.
Indeed, but if you diff them on the CD you'll find that they do not differ, so why would they have diifferent md5sums (which md5sum.txt claims)?
Quote
The third is ./casper/filesystem.squashfs. I'm sure that does matter.
Given that the other files in casper/ are wrongly listed in md5sum.txt, I'd assume that it is the list which is wrong.

I was unable to burn a cdrom of the iso file. I suspect that it is just a hair too big. I burned it onto a USB key instead.

2 -- Has anyone actually successfully booted from this disk?
Sort of.  I'd actually burnt it to a DVD (I needed an iso image for a test and knew where this one was, so used it.  Just tried it for you and it certainly booted (I'm now looking at a heron on my laptop).
435  Hardware and U-Boot firmware / U-Boot stuff / Re: Trouble using ext2ls/ext2load on: July 24, 2009, 05:46:28 AM
2. For some reason, the ext2ls and ext2load commands are only capable of accessing the first partition on an SDcard.
I'm still waiting for my Plug to be sent, so can't test anything.
But - I can make a random guess at a possibility.
When you say "second partition", do you mean that, or do you mean "another partition".  Is this second partition really (e.g.) /dev/sda2, or is it /dev/sda5, which would be a logical partition?
