David,
I'm not running SixXS tunnel on CentOS right now. I'm planning to have
some. Right now I have one tunnel on OpenWRT and I'm using this script.
Regards,
DH

ip tunnel add sixbone mode sit remote ipv.addreess.of.sixxsendpoit
ip link set sixbone up
ip addr add ipv6:address:of:tunnel::2/64 dev sixbone
ip route add default via ipv6:address:of:tunnel::1
ip link set mtu 1280 dev sixbone
ip tunnel change sixbone ttl 64

If you finished your dd_rescue/ddrescue copy, you may want to look into 
the testdisk utility to see if somehow the partition-table was not 
tampered with. testdisk can provide you with different layouts based on 
filesystem patterns. And it also saves the original layout so you can 
restore that as well.

Also beware that a complete image includes the partition table, and 
loop-back mounting by default expects the filesystem image. So you may 
have to provide also an offset= option to tell mount where to look for the 
actual filesystem on the image !

If the files on the disk are a common format and the filesystem for some 
reason is nuked, photorec might help recover data from the disk. But 
beware, it may be very time-consuming to restore whatever photorec thinks 
it can identify. For simple digital camera media this works much better 
than a full disk with eg. operating system.

Before trying an fsck on a backup copy, first try an fsck -n and see if 
the output is only minimal or not. Possibly try with different 
superblocks as well. You don't want to have to make another copy just 
because the filesystem is so broken, it can never be restored using fsck.

Good luck, and provide feedback, we might learn a trick or two :)

exactly, and there are additional packages in 6.1 that weren't ready
when 6.0 was released.

Considering that it took them 3 months to get out the 5.6 update and
that upstream is adding packages that weren't ready when 6.0 was
released, I would think that one month is highly optimistic but two
things are certain. Upstream released exactly 6 months ago and still
nothing and apparently today's target date has slipped, and 2) until
CentOS admits that there is a problem, nothing will actually change.

6.1 will be already released. So there will be no security updates for
C6.0, and it will be better to stay under SL6, until the release of
C6.1. I already installed three machines under SL6, and it works fine.


Once 6.0 packages are figured out (how to compile them), newer versions
of those packages in 6.1 will be much easier to compile, so I expect no
more then one month to pass from C6.0 to C6.1


Do you expect the C6.0 -> C6.1 differences to be more complex, or less 
complex than the C5.5 -> C5.6 differences ?


And given that C5.6 took 3 months, are there any reasons why C6.1 would 
take no more than 1 month ?

Re: [CentOS] ipv6 to ipv4 tunnel private replies requested

[David Mehler]

Hello,
I am afraid a comment in my last message was misinterpreted. I
previously had this configuration, linux and ipv6 tunnel through a
tunnel broker. It was on a Ubuntu 9.10 box that a friend of mine set
up. That box has been retired and replaced with CentOS 5.6. I am now
trying to get the tunnel broker working with the centos box, and
having many frustrations with it. I do have the ubuntu network files
from backup, but I to date have not been able to make them work,
settings wise, with the way centos does networking, I would almost say
forget the backup files just take the numbers out of them. I
appreciate any help. Again, private replies please.
Thanks.
Dave.

binary drivers are *very* kernel version specific.

you could install centos 5.4 with those drivers, then yum update

I am sure it doesn't. I have booted 5.5 and 5.6 in linux dd mode. Then I have 
loaded the drivers from: aacraid-driverdisk-CentOS.iso . Still, the installer 
sees no hard disk. I have read somewhere, that the adaptec driver to that 
controller works only with Centos 5.4, but i need a newer version of Centos. 
Maybe using drivers from RHEL 5 / 6 would be a better solution here?

 And this is normally done, except I was in the middle of working on 
something when I needed to reboot for non-related reasons.  So for the 
most part I have a backup, but it's about 24 hours behind where I was.  
That's 24 hours I don't necessarily want to lose.

 I don't know about that particular device, but I've seen RAID
 controllers where you had to run their bios setup utility to add disks
 and create volumes even if you only want a single disk per volume.  The
 OS only sees the volumes as logical drives.  Or have you already done
 that step?

Yes. The problem is that Centos 5.6 has no valid driver for Adaptec 6405

mke2fs -n /dev/hde1 should list you the block addresses where copies of
the superblock would be found.

Set ASB=any one of the alternate blocks listed.
Then, try mount -t ext3 -o sb=$ASB /dev/hda2 /mnt

[CentOS] Drive recovery?

[Ashley M. Kirchner]

 I have a CentOS 5.6 system (recently installed) that, for some 
reason, has decided to mangle one of its drives, specifically /dev/hde1 
...  No errors anywhere, just rebooted the machine over the weekend and 
it's gone.  Up till the reboot, the drive was fine, I was writing to it 
without a problem.

 fdisk tells me:

--
# fdisk -l /dev/hde

Disk /dev/hde: 160.0 GB, 160041885696 bytes
240 heads, 63 sectors/track, 20673 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Device Boot  Start End  Blocks   Id  System
/dev/hde1   *   1   20673   156287848+  83  Linux
--

 There are no hardware errors in the boot log (dmesg).  The only 
error is that it can't find the ext3 fs that was on that drive.  
Unfortunately, it's not a drive I can simply reformat and call it a 
day.  There's data on it I need.

 When I try to mount it, I get: hfs: unable to find HFS+ 
superblock.  Obviously that's not right as the drive was formatted as an 
ext3.  So if I force it, I get this:

--
mount -t ext3 /dev/hde1 /mnt/hde1
mount: wrong fs type, bad option, bad superblock on /dev/hde1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail  or so
--

 So, is this just an indication that the partition table is hosed?  
Is there anything, any tool, any way of reading the data off of this 
drive and put it elsewhere?

Re: [CentOS] ipv6 to ipv4 tunnel private replies requested

[Steve Clark]

Yes,

We are using one to HE and one to SIXXS. We don't rely on any of the standard
redhat config stuff - we do it all thru our own configs.

Been working great.

I'm not quite clear on your answer: are you saying that you created
logical RAID volumes, added the physical drives to it, and initialized
each volume?

Maybe it needs a newer aacraid driver than what is included.  Have you 
tried the 1.1.7 driver disk that you can download from the adaptec site?

I have and array setup in the controlers BIOS. What i need to do is to install 
centos on the logical volume. Still, Centos 5.6 seems not to have any drivers 
for Adaptec 6405.

I remember fighting with this kind of issue.
let's see
OK, I have this in my .bash_profile :

# no default locale, this is BAD and breaks eg normal sort!
#export LC_ALL=C
# commented that to try to use UTF8 (be more modern), and it
# broke printing with evince because the stupid program looks
# at LC_PAPER for that (and prints in letter with the default
# en_US.UTF-8 locale)
# en_GB should print in A4 by default
export LC_PAPER="en_GB.UTF_8"

I don't know about that particular device, but I've seen RAID 
controllers where you had to run their bios setup utility to add disks 
and create volumes even if you only want a single disk per volume.  The 
OS only sees the volumes as logical drives.  Or have you already done

[CentOS] Changing default paper size to A4 on CentOS 5 (Kyocera FS1920 printer)

[Mathieu Baudier]

Hello,

I have a Kyocera FS1920 network printer, and I run an up-to-date
CentOS 5.6 x86_64 workstation.

When I try to print with evince or Firefox the default paper size is
always set to US Letter whereas the printer use A4.

I have searched and other people seem to have the problem, but the
only recommendations that I have found boil down to setting the
default paper size to A4 in the CUPS printer settings.
I had done that already and double-checked via the Printer config UI
or the CUPS web interface (http://localhost:631), but to no avail.

What is a bit weird is that I do not remember having such problems
with my previous printer (an Epson Stylus RX500).

I would be grateful for any hint / idea.

Cheers,

Mathieu

Re: [CentOS] RHEL 6/CentOS

[Kevin K]

If I had to guess, it would be that the OS is considered an "enterprise" OS, 
and that the CPU is too low end, now, to be considered that.  It is kind of low 
end now for even personal use.

Not that people only use the OS for high end server hardware :)

At work, we still have to support 500MHz Pentium IIIs with 128MB of RAM.  
Hopefully that requirement will be dropped before we migrate to 6.  We had to 
make kernel modifications to even get the PCMCIA support to work on it.

Once 6.0 packages are figured out (how to compile them), newer versions 
of those packages in 6.1 will be much easier to compile, so I expect no 
more then one month to pass from C6.0 to C6.1

When I visit servers to make changes, I almost always check
/var/log/messages and dmesg for latent errors or other issues that I can

Thankfully, the only in-place upgrades I'll really consider is to 
cross-grade SL6 to C6. I've started testing with SL6 and will happily 
report to everyone how the cross-grade goes as soon as C6 is out!



-Ben




Hi,

The problem is that when C6.0 will be released, it is likely that RHEL 
6.1 will be already released. So there will be no security updates for 
C6.0, and it will be better to stay under SL6, until the release of 
C6.1. I already installed three machines under SL6, and it works fine.
