One of the configuration parameters I believe is how much the time can be
out befor it is considered insane. I know it exists in chrony, and believe
it also exists on ntp.

(eg on chrony it is the parameter maxupdateskew)

However you probably also want to figure out why backups are destroying
your clock. Somehow the timer interrupt is being ignored. You may have set
the priority on disk interrups too high somehow.

Effectiveness of ntp under Redhat Linux FC3

Posted: 20 May 2005 11:39 AM PDT

Sounds old, isn't the FC3 update kernel even more recent?
 

Ntp can be configured to ignore this behavior which does indicate
some serious problems. IIRC it will ignore the problem only once
and exit if this happens again. Should be all in the fine manual
'man ntpd', should be the first thing to try, checking the docs
coming with the package.

If the backup happens at a scheduled time, you could run a script
from cron or the backup software, stopping ntpd and later using
ntpdate to set the clock and restart ntpd. Sure this is a bit
clumsy but the real problem is related to your broken hardware.

New linux user - partition / mbr question....

Yes, i have indeed foobarred myself by the sound of it. I can't put the
partition back can I? Or just putting a partition there should do the
trick? Is there not a way to reconnect the winxp installation with the
appropriate boot files, rather that trying to recreate the partitions
that existed when it was installed?

I've tried putting a new installation of XP on, but when it goes to
reboot during setup, the reboot leads back to the blank screen, so that
doesn't seem to be an option.

Linux native unicode support?

Posted: 19 May 2005 04:18 AM PDT

Yes, depending of what is understood under "Unicode". Linux knows what to do
with UTF-8 if set up properly. It will have problems with UCS-2 (as used by
Windows). Both may in some sense be called "Unicode" :)
 

So what? As long as Unicode in the input encoding is displayed properly?
 

Yes, that is (may be) a problem. Linux text console has room for 512
characters only (I have heard of pathes that enable font switching on the
fly) so you probably cannot stuff very much in it. GUI is better but even
then konsole does display quite a lot of rectangles when I cat KDE desktop
file with all translations. In any case, you need not *one* font but font
set that covers those Unicode planes you need.
 

You mix viewing and processing. Program may process Unicode correctly even
if system is not setup to display it. (less is not unicode aware BTW at
least w.r.t. to editing command line so you cannot enter search string if
character set is multibyte).

LILO+RAID+LVM or EVMS (+GRUB) ?

Posted: 18 May 2005 03:07 PM PDT

Peter T. Breuer wrote: 

It was the robustness I was going for, but maybe a 4 disk RAID1 is a bit OTT.

Maybe 2x2 disk RAID1s as swap partitions. The server "shouldn't" ever start to
swap though, they are there "just in case", so back to plan A with swap on
RAID then :)
 

I think a root-RAID is a good thing, and lilo supports automatic update of all
the MBRs in a RAID1 setup using the raid-extra-boot option.
 

My root has /boot on it, I didn't want to mess about with another partition.
 

Yepp :)

grub problems: rootnoverify / chainloader problem

Posted: 15 May 2005 11:17 PM PDT

org a écrit : 

This is not an error message. This is the normal way for grub to boot WinXP.

What happen when you just wait?

You could also try to use the autocompletion of grub when booting to
guess what are the different partitions you can boot on:

when you first see the boot menu of grub, just press c to get into the
command mode.

Then try to write "rootnoverify (" and then press the 'tab' touch. Grub
should guess your different partitions.

As for the question of choosing sda, sd0, hda hd0, remind you that sd
calls for scsi devices and hd for ide ones. Then the linux system uses
letter a,b,c,... (depending on which ide place it is linked and if it is
a master or a slave) and the grub system uses number 0,1,.. in the same
order as it appears in the bios list of hard drive.

Hope to help you.

DHCP issues with Fedora 3

Jon,

Haven't got much troubleshooting methodology to offer but I just installed
and in rapid succession upgraded Fedora Core 3 on a new Dell 470
Workstation.

Before I moved this machine into prime position it was sitting at the
other end of my home network receiving DHCP assignments faultlessly from
its aged bretheren 410 workstation running RH8.0. Now that the tables are
turned, the 410 is getting its IP and DNS assignment uneventfully from the
470.

I've upgraded the stock kernel twice, first to 2.6.11-1.14 and then to
2.6.11-1.20 with no change in the behavior either time.

Of course, it's necessary to review fire wallsettings, but a kernel
upgrade won't alter that.

So, the only value of this is to let you know it can work.

Frank

p.s. Scanned your posting one last time before hitting send and need to
tell you that I've also updated all applications on the FC3 machine
through apt/synaptic from freshrpms, ayo, and planetccrma, so that should
be pretty close to your experience. One last thing - you might want to
post exactly what was working that isn't now. Is it only DHCP? How about
IP forwarding (Internet connection sharing), or SAMBA (accessing Window's
shared resources)?

problems with Gentoo (messages on startup, installing gnuplot, running KDE)

The solutions:

# USE="-hardened" emerge gcc
# USE="-svga" emerge gnuplot
# emerge -C xorg-X11
# emerge -C ccache
add "-fPIC -pie" to USE in make.conf
# emerge xorg-X11
Configure X server.
When configuring kernel tick off option like 'mount /dev on booting',
rebuild kernel.

Thanks to all who gave any clues (usenet, maililng list, gentoo forums).

How many partitions?

Posted: 14 May 2005 09:17 AM PDT


"Ben Wylie" <com> wrote in message
news:gwphe.2917$ntli.net... 

CentOS is not really a "kind of server". It's a "kind of OS". If you're
running a news and email server, for example, you will want your news or
mail spool to be a partition that handles lots of little files very well,
such as a ReiserFS or ext3 partiton with "noatime" set. If you're running a
development box on which you're building lots of kernels, it may be handy to
have /tmp, /usr/tmp, /usr/src, /usr/local/, etc., etc. all on the same
directory so that you don't have to worry about re-allocating space from one
to the other.

A lot of the reaon for lots of small partitions has to do with old, small
disks that couldn't hold much material, and backup tools that had to be
bootstrapped onto a teeny little / directory, then botstrap things onto
/etc, then restore the other directories from backup tapes. This forced
people to break things up into lots of different partitions.

These days, a 200 Gig drive is easily allocated into a 40 Gig space for the
OS, another 40 Gig space for home directories in case you want to swap OS's,
and another 120 Gig of scratch space, with say 4 Gig set aside for swap
space.

grub:how it works under the hood

Posted: 10 May 2005 03:10 PM PDT

com writes:
 
 

No, it does not. It uses the bios to read the appropriate raw sector of the
disk containing the kernel. Grub uses the bios to read a small (but larger
than Lilo) grub program which can also read the sector containing the
description file to tell it where the various possible kernels are. Ie,
instead of saving them in the MBR it saves them in a file which is read in.

 

It uses the info in the grub.conf file.
 

 

list subdirectories on a particular partition

Well, this isn't a HPUX newsgroup, and it isn't a Linux (it's a branded
Unix), but what else does 'df' tell you? It should show disk usage for
all mounted partitions. Thus, if there is only one partition, you're
out of luck. If it has MORE THAN one partition listed, then look at
what they are mounted as:

[compton ~]$ df
/dev/hda1 608785 550356 26981 95% /
/dev/hda3 1247309 1040146 207164 83% /home
[compton ~]$

The first line talks about root. The second line refers to another
partition that is mounted as /home. This means /home (and everything
below /home) isn't on the first partition, and that everything below
home is mounted on the second listed partition.
 

'df' and 'find' should do the trick.
