Ugh, hasn't RedHat fixed that?  Sun have (for a long time) automatically

*sigh*.

So my previous mail should really be
  df -Pkl | awk '/^\/dev\// { avail += $3/1024 } END { printf("%d Mb 
used\n",avail)} '
  

Hi,

This is work well on my laptop that running Fedora 9 with no LVM but on 
CentOS 5.2 with LVM it cann't calculate the LVM volume, below is output 
of my system :


[EMAIL PROTECTED] ~]# df -kPl
Filesystem 1024-blocks  Used Available Capacity Mounted on
/dev/mapper/VolGroup00-LogVol00 274405432  18584656 241656808   8% /
/dev/sda2   101105 19096 76788  20% /boot
tmpfs  1682508 0   1682508   0% /dev/shm

and with the command of Stephen :
[EMAIL PROTECTED] ~]# df -Pkl | awk '/^\/dev\// { avail += $3/1024 } END 
{ printf("%d Mb used\n",avail)} '

18173 Mb used

So it seam to be bot calculated on /dev/mapper/VolGroup00-LogVol00
I am just a newbie with Linux and stupid enough to not to know how to 
fix the command so just post it and hope you guys can improve the script ;)


Thanks for the tip.

Have fun.

One book you might consider purchasing is "Fedora 9 and Red Hat
Enterprise Linux Bible"  (Wiley)) (Paperback). I do not have
that edition, which just came out, but I have several previous
editions. I am certain there are many other great books about RHEL.
CentOS
is a binary clone (with few exceptions) of RHEL. In addition to the
great data on the CentOS WIki, you can download some of the manuals
from our upstream (RH) on the CentOS web site. Possibly more manuals
are available on the RH web site that you can download. As another
poster pointed out, if you subscribe to and read this mailing list,
you WILL learn. Another good method is "learn by destroying".

To prevent the mix-up of partitions sequence during installation, here's
what I do (sorry for the copy paste :))
1. Build a 100MB RAID-type partition on each disk
3. Build a RAID 1 device over the small partitions
2. Build a second RAID-type partition taking the remaining space on each
disk
4. Build a second RAID 1 device over the bigger ones

That way /dev/{sda1,sdb1} will surely be /dev/md0, and /dev/{sda2,sdb2}
will be /dev/md1.

To address the second issue of grub is not installed on the second RAID1
disk, I thought it was an old bug in Centos4.0 which since then has been
fixed. I'm not sure if it's related, but as a workaround you can try
labeling the raid array so that it wont matter if the computer
recognizes it as sda or sdb. Here's a good article:
http://cgerada.blogspot.com/2008/07/software-raid-on-linux.html

Going to google, "tightvnc IPv6":
http://www.tightvnc.com/related.html
which then points (at the bottom):
http://jungla.dit.upm.es/~acosta/paginas/vncIPv6.html

so it looks someone has compiled TightVNC with IPv6 support.

Try the new font fix, and see if it works

 You would think installing via yum would handle dependencies, but

 Anyway, I installed tightvnc to test out its IPv6 support.

 Installed ok (after I erased regular vnc). But when I tried to start it,
 I got 5 warnings about:

 Font directory '/usr/X11R6/lib/X11/fonts/misc' not found - ignoring
 (then the same message for Speedo, Type1, 75dpi, and 100dpi).

 Then a fatel server error about: could not open default fount 'fixed'

 So I looked in the repos (curtesy of yumex) and did find a few 75dpi a
 100dpi fonts, but there seemed to be a lot of these two. I installed a
 ocuple of them and tried again. Got the same errors.

 So how do I fix this one?

Robert, I noticed the same thing, so what I did is the following:

cd /usr/X11R6/; mkdir lib; cd lib; ln -s /usr/share/X11 .

Now try it.  Seems like the repository from which I got TightVNC has
issues in directory compatibility  but at least I got it working.

I didn't have a misc fonts directory, and my $HOME/.vnc/xtartup has:
#!/bin/sh

# Red Hat Linux VNC session startup script
exec /etc/X11/xinit/xinitrc

If that still doesn't work, I'll post the /etc/init.d/vncserver script
that works for me (possibly from an older install of tightvnc - 1.2.9
I believe).

If there's a more elegant solution, someone please let us know!  :-)

S400 is 400 megabits, while USB 2 is 480 megabits. Firewire has less 
packet overhead, which might explain WD's claim that the FireWire 
interface is a little faster.

And isn't firewire DMA capable while USB is PIO?

My experience with Firewire has not been all that good.  I figured that
since Apple had been using it for years, and it is an IEEE standard, that
Firewire would be more reliable than USB.  I was also a bit wary as the USB
disk drivers on SuSE gave warning messages saying they might not be very
reliable.

I first used Firewire external drives in 2003 on whatever was the current
version of SuSE Pro at the time, and on a FreeBSD 4.8 system, and have
Firewire drives on several SuSE systems up to SuSE Linux Enterprise 10.

The FreeBSD machine has never shown any problems with its FW drive, but the
SuSE systems often seem to stop talking to the drive for no apparent
reason.

At this time, most of our Linux boxes are running USB 2.0, and the external
Firewire-only drives are all on our Macs which seem to have far better FW
support than Linux.

[CentOS] DRBD 8.2 crashes CentOS 5.2 on rsync from remote host

[Chris Miller]

I've got a pair of HA servers I'm trying to get into production.
Here are some specs :

Xeon X3210 Quad Core (aka Core 2 Quad) 2.13Ghz (four logical
processors, no Hyper Threading)
4GB memory
Hardware (3ware) Raid 1 mirror, 2 x Seagate 750GB SATA2
650GB DRBD partition run on top of an LVM2 partition.

CentOS 5.2 2.6.18-92.1.6.el5.centos.plus
DRBD 8.2 (drbd82-8.2.6-1.el5.centos)
Kernel Module kmod-drbd82-8.2.6-1.2.6.18_92.1.6.el5.centos.plus

I've been trying to rsync data from a remote server and it's crashed
a couple of times now. It does not happen immediately, but over
time. I connected a serial console and got the below panic message.
The last file copied was ~1GB in size, but previous files up to 4GB
had been copied. I do not have kernel core dumping enabled, but
that's a possibility if needed. Not sure if this is a bug or is
caused by something I've done. This isn't my first DRBD install
(although first on top of LVM) and I believe I've gotten everything
setup correctly. I did have a full sync rate (110M) enabled over
Gbe, if that's relevant. Thoughts?

Chris

dump is 200 GB, and I've found the "one file" dump more reliable and 
efficient than the multi-file feature, which breaks the dump into lots of 
little 1 GB files.


I format mine with NTFS for OS interoperability and mount using the ntfs-3g 
FUSE filesystem.


Say the partition is labeled "Backup1". Then I can mount it with:

mount /mnt/Backup /dev/disk/by-label/Backup1 -t ntfs-3g

Ouch!
Sure /boot/grub/grub.conf still needs editing...
That's why you really, really WANT both partition tables to be identical...

[CentOS] rtc in /proc/interrupts

[Jerry Geis]

Hi - I am using centos 4.6 on an ebox 4300. Everything seems to be 
working except the
/proc/interrupts rtc is always constant. On other machines the rtc 
(which ztdummy from asterisk) is always incrementing.

the uhci_hcd and ehci_hcd are both running.

What can cause this?

Re: [CentOS] can't get Ethernet SNMP information

[Marc Grimme]

Hi,
I didn't follow the whole thread but had the same problem when using net-snmp 
with bridges (an I see peth0 and that rang the bell). The problem seems to be 
that net-snmp does not like nics with same ips (I didn't find very much on 
that topic). You should see some errors from net-snmp in the syslogs of your 
managed servers. What does your syslog say?

I solved it by changing the bridge configuration from the scripts provided by 
xen /etc/xen/scripts/network-bridge to using ifcfg bridges. Then cacti could 
monitor the interfaces like normal.

Hope that helps.

It certainly looks like cacti is finding a bunch of stuff, what
does the status column say to the left of the green circle? For
my test system it says -

Success [24 Items, 4 Rows]

When you go to the 'Create graphs for this host', do you see just
the Header with nothing below it? (Data Query [SNMP - Interface Statistics])

What version of cacti? Though it shouldn't matter this is a pretty
basic thing.

[CentOS] Boot from degraded sw RAID 1

[Eduardo Grosclaude]

OK, this is probably long, and your answer will surely make me slap my
forehead really hard... please help me understand what goes on.

I intend to install CentOS 5.1 afresh over software RAID level 1. SATA
drives are in AHCI mode.

I follow basically [1] though I have made some mistakes as will be
explained. AFAIK GRUB does not boot off LVM, so I:

1. Build a 100MB RAID-type partition on each disk
2. Build a second RAID-type partition taking the remaining space on each disk
3. Build a RAID 1 device over the small partitions
4. Build a second RAID 1 device over the bigger ones
5. Declare /boot as ext3 to live on the smaller RAID 1 device
6. Declare an LVM PV to live on the bigger one
7. Build a VG on the PV, then build LVs for swap, / and /data on the VG

Only problem is, I numbly have failed to follow [1] in that I left
Disk Druid to make partitions wherever it chooses, so now I have
cross-named partitions... md0 is the bigger RAID 1 device with
/dev/sda2 AND /dev/sdb1... and md1 is the smaller one with /dev/sda1
AND /dev/sdb2. Oh well, things can't get complicated on this, I tell
myself.

Installation goes on well, system boots. I update the system. Now I
want to be able to boot from whichever disk survives an accident. If I
take out sdb, system boots. If I take out sda, system refuses to work.
Aha. GRUB is not installed into sdb's MBR. Reconnect sda, reboot.
Prepare for GRUB device juggling as in [1].

Into GRUB console I do
> find /grub/stage1
hd(0,0)
hd(1,1)
> device (hd0) /dev/sdb
> root (hd0,1)
Filesystem type is ext2fs, partition type 0xfd
> setup (hd0)
 Checking if "/boot/grub/stage1" exists... no
 Checking if "/grub/stage1" exists... yes
 Checking if "/grub/stage2" exists... yes
 Checking if "/grub/e2fs_stage1_5" exists... yes
 Running "embed /grub/e2fs_stage1_5 (hd0)"...  15 sectors are embedded.
succeeded
 Running "install /grub/stage1 (hd0) (hd0)1+15 p (hd0,1)/grub/stage2 /grub/grub
.conf"... succeeded
Done.
> quit

The rationale for this being that, when the faulty disk is removed at
boot, the remaining one (currently /dev/sdb) will be addressed as
/dev/sda (i.e. hd0 in GRUB parlance).

Now I prune /dev/sda and reboot. I see:

root(hd0,0) <--- interesting
Filesystem type unknown, partition type 0xfd
kernel /vmlinuz-2.6 ro root=/dev/VolGroup00/LogVol01 rhgb quiet
Error 17: Cannot mount selected partition
Press any key to continue...

Not quite what I expected. I enter GRUB console at boot and repeat the
above device juggling.

> find /grub/stage1
hd(0,1)
> root (hd0,1)
> setup (hd0)
> quit

However, 'quit' seems to fail as grub keeps prompting me without
really quitting. After a forced reboot I get the very same error
message as above.

I edit the GRUB configuration entry at boot (with e command) and see
root (hd0,0)
as the first line

It should be root(hd0,1), so probably GRUB did not write down my
modifications. I edit it to read so (e command again), and then boot
(b command). Now it works. I rebuild the arrays succesfully. However,
I have made a one-time edit and the problem is still there.

I understand the error message from the booting process was
reasonable: hd(0,0) carries an unknown filesystem -- an LVM device.
[1] was right, you definitely want to have exact disk duplicates to
keep your life simple.

However, I can't see why it shouldn't work the way it is. I can
probably rebuild the secondary disk to mimic the primary's partition
numbering and "fix" my problem...

But, Am I right about the GRUB console commands I was issuing? How can
I make them permanent then? I KNOW I did 'quit' from the grub console
the first time, when from inside bash, when the system was running.
What am I missing?

Thank you in advance

Have you actually tried to solve this problem yourself? I know nothing about

sounds a lot like what you describe.

in google you might just get the info you need. Do not forget to include the

This is the exact problem we were having here. Rebooting is the only
solution.

And as already mentioned further down the thread it was attributed to
this https://bugzilla.redhat.com/show_bug.cgi?id=453094

My solution was to extract the patch from the upstream kernel in 
http://people.redhat.com/dzickus/el5/103.el5/src/
called
linux-2.6-fs-lockd-nlmsvc_lookup_host-called-with-f_sema-held.patch

and reroll the latest centosplus kernel srpm with it. Servers have been
fine for 6 days running this kernel.

As much as I hate carrying custom kernel rpms this is a showstopper for
us, and it looks like it won't make in until 5.3. 

Personally given the limited scope of the patch and apparent
unwillingness of redhat to include it in an update I'd advocate CentOS
carrying it as a custom patch.

I remember playing games with Matlab to get it to find it's own fonts. I 
think it went something like:


mkdir

mkfontdir

Like you say, maybe just a link to /usr/share/X11/fonts/misc would do 
the trick.


Perhaps a vnc/X startup script somewhere is hardcoded?

Very strange, can you include the output of the verbose query? What
version of cacti?

This is what I get, though I don't use this method to get network
stats from my systems, I have scripts that gather it for me(they
return about 20 points of data that I put into a single RRD per-host,
vastly improving performance by 10x+, though it's a labor intensive
process to add a new system to cacti for me as cacti wasn't designed
for doing things the way I'm doing them).

The GNU readline library, which is where bash gets it's command-line

Personally I think the only vi command one needs to know is ":q!".

Try restarting nfslock on both client and server when it occurs?
Or try setting up a cron to restart nfslock hourly on all systems

Actually I tried restarting both nfslock(on clients and server) and 
nfs(on server) but it didn't help.

Is my solution with mounting it nolock bad?

I was also thinking about mounting the nfs shares as soft, is this a 
good idea? Could it help me? And also, what's the difference between 
soft and intr?

Read the manual and I thought they were pretty similiar.

And cacti still doesn't see the interfaces? Did you change
the snmpd.conf after adding the device into cacti? Cacti
doesn't automatically pick up new devices, you have to tell it
to re-issue the SNMP query. In the device page for the server
click on the little green circle, I think that's the link that
tells cacti to re-scan the device.

My cacti consoles aren't easily accessible from where I'm at
so I can't verify exactly right now.

I've never seen cacti not pick up the interfaces when
the SNMP permissions are correct. And it sounds like yours
are fine, at least right now.

Take a look at system-config-kickstart to help build your kickstart
files.

Anyway I think what you are looking for is,

# Clear the Master Boot Record
zerombr
# Partition clearing information
clearpart --all --initlabel

Copy the DVD put the ks.cfg file in the root of the DVD files

vi //isolinux/isolinux.cfg and edit the append line or add a
new entry like this

label yourlabel
  kernel vmlinuz
  append initrd=initrd.img ks=cdrom:/ks.cfg

Make iso and burn as described here:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/x8664-multi-
install-guide/s1-steps-install-cdrom.html

Boot DVD and type "yourlabel" to activate your kickstart file.

Run a snmpwalk against your system's full tree and count the lines
just to verify that it's wide open

snmpwalk -v1 -c public localhost .1 | wc -l

One of my systems returns over 4500 lines, if yours is returning

Clonezilla is designed with your intent in mind. I believe it should 
support lvm & sw raid.


www.clonezilla.org


Clonezilla is great for single disk images and can handle lvm and 
windows partitions, but it doesn't do software raid unless you create it 
yourself and use partition copy mode.  Clonezilla will be the fastest 
way if the machines have a single disk or hw raid - it is very fast and 
you'll only have to change the hostname and IP of the finished copies. 
For a few machines you can use the clonezilla-live bootable iso and 
connect to a network drive for the images via nfs, smb, or ssh.  For a 
large number of machines you can install the companion drbl program to 
pxe-boot into clonezilla with the image storage already mounted.


Next best in speed would be a kickstart install - and again you can use 
a minimal-setup approach for a small number of machines by dropping the 
file created by your initial install onto an existing web server and 
giving the URL at the boot prompt of a DVD or NFS install, and the 
simple way to do additional setup is to export an NFS share with the 
content and install script you need do drop it in.  It's a couple of 
command lines to mount the share and execute the script.  If you have a 
very large number of machines you can automate it completely with 
cobbler - or the drbl progran can be configured to do kickstart installs 
too.

Where did you install TightVNC from? RPMforge/DAG has an
RPM for it (version 1.3.9-3.el5.rf for CentOS 5).
  


Yes. That is what I have and where I got it.


If that still does not fix your problem, then try installing
"fonts-xorg-100dpi" and "fonts-xorg-75dpi" as well.
  

For Centos 5, there are a number of fonts-xorg-100dpi, a '14' a '15' and I
don't recall what else I found with the help of yumex.



I only have xorg-x11-fonts-ISO8859-1-100dpi and
xorg-x11-fonts-ISO8859-1-75dpi installed here, and I never had
problems with fonts.

ISO8859-1 is a character set also known as Latin-1, it has fonts for
most western alphabets.

ISO8859-14 and ISO8859-15 are character sets with special characters
for (I believe) easter European countries. I believe one of those is
the same as Latin-1 but with an extra Euro sign, for example. I don't
think you need those, at least not to run TightVNC. Your problem is
probably not there.

I have all of these :)

Well, that's the thing, in Cacti there' an option, "SMP Interface
Statistics" - which you need to enable first, and then select the different
interfaces. It's supposed to list eth0 - xenbr0, and everything in between,
but it doesn't.

I'm not an expert on Cacti, but... are you sure you configured the

eth0?

Yes, you may try to create symbolic links to have the fonts on the
other path. I'm not an expert on X11 here, but I don't think
applications would have font paths hardcoded. It might be worth the
try though. Where did you install TightVNC from? RPMforge/DAG has an
RPM for it (version 1.3.9-3.el5.rf for CentOS 5).

I only have xorg-x11-fonts-ISO8859-1-100dpi and
xorg-x11-fonts-ISO8859-1-75dpi installed here, and I never had
problems with fonts.

ISO8859-1 is a character set also known as Latin-1, it has fonts for
most western alphabets.

ISO8859-14 and ISO8859-15 are character sets with special characters
for (I believe) easter European countries. I believe one of those is
the same as Latin-1 but with an extra Euro sign, for example. I don't
think you need those, at least not to run TightVNC. Your problem is
probably not there.

[CentOS] libc.so.6(GLIBC_PRIVATE)(64bit) is needed but I cannot find it in CentOS 5.2

[Erez Zilber]

Hi,

I hope it's the right list. Anyway, I'm using CentOS 5.2. I wrote a
program that uses rtkaio (so my Makefile contains -lrtkaio). The
program runs successfully. The
problem began when I wanted to create a rpm for my program. I was able
to generate a binary rpm, but when I tried to install it, I got the
following error:

[EMAIL PROTECTED] tmp]# rpm -i /tmp/mypkg-1.0.x86_64.rpm
error: Failed dependencies:
   libc.so.6(GLIBC_PRIVATE)(64bit) is needed by mypkg-1.0.x86_64.rpm

I checked the dependencies:

[EMAIL PROTECTED] tmp]# rpm -qRp /tmp/mypkg-1.0.x86_64.rpm
/bin/bash
/bin/sh
/bin/sh
/bin/sh
/usr/bin/python

libpthread.so.0(GLIBC_2.3.2)(64bit)
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rtld(GNU_HASH

The problem is that librtkaio uses GLIBC_PRIVATE:

[EMAIL PROTECTED] tmp]$ nm /lib/rtkaio/librtkaio-2.5.so | grep PRIVATE
U __libc_dlopen_mode@@GLIBC_PRIVATE
U __libc_dlsym@@GLIBC_PRIVATE

w __pthread_clock_gettime@@GLIBC_PRIVATE
w __pthread_clock_settime@@GLIBC_PRIVATE
U __pthread_unwind@@GLIBC_PRIVATE
U _rtld_global@@GLIBC_PRIVATE

But I couldn't find where these symbols are defined (e.g.
__libc_pwrite@@GLIBC_PRIVATE).

The workaround that I found is to add the following line to the spec
file: "provides:libc.so.6(GLIBC_PRIVATE)(64bit)"
I guess that there should be a better solution for that. Any idea?

Thanks,

[CentOS] Storesonline, Website Design For Ecommerce The Three Things You Must Get Right

[Mister Nice Guy]

*Storesonline, Website Design For Ecommerce The Three Things You Must Get
Right*

If you're planning to sell goods or services online, you'll need an
ecommerce website. As this will be your shop front, your showroom, your
salesman and your cashier, you'll appreciate how important it is.
Essentially, the success of you ecommerce website depends on getting three
factors right - design, usability and search engine optimization.*Storesonline
* provides  these services for the client.

First, let's look at design. Design is important as it influences the
impression your visitor gets of you and your business. Your website should
be attractive and solidly professional. This assures the first time visitor
that you are the right company to do business with.* Storesonline* software
offers you point and click design. In addition, your website should reflect
your brand and mission statement.

Next there's the matter of usability. *Storesonline* software allows for
easy navigation for customers. This determines how easily your visitor can
navigate your site. The first thing you have to consider is the mechanics of
your business model. You have to decide what you want your visitor to do and
then give him clear means to do it.

One factor that promotes clear navigation is making sure all links are well
labeled. For example, "Click here for more details on our refrigerators" is
much more useful that just 'click here' or 'more information'. And your
visitor should always know his location and how to return to your home page.
Remember if your visitor gets lost on your website, he'll just click away,
probably never to return.

Re: [CentOS] Help setting up external drive via Firewire

[Noob Centos Admin]

Scratch that last message. I removed the drive to verify the copied content
on another machine and realized I forgot to copy one folder. Plugged it
back, with the wrong connector, using the Firewire instead of USB, probably
because my mind was still on the Firewire issue.

This time round, gnome desktop automounted the drive and there it was on my
desktop to my surprise.

Checking with mount
/dev/sde1 on /media/My Book type vfat
(rw,noexec,nosuid,nodev,shortname=winnt,uid=502)

I've no idea why or what happened, just glad it works! :D

Now testing it out with another day's data about 112G worth and Nautilus is
estimating about 60 minutes, so that's about 31.8MB/s or 29% faster.
Although Nautilus was a bit optimistic with the previous transfer so the
Firewire still likely a good 20% to 25% faster.

The problem with Firewire is that you need
a) a "good" chip in the controller
b) a "good" chip in the Firewire-to-SATA controller in the external 
unit (there are no native firewire disks...)


That's what makes IEEE1394 always a bit of a gamble.


There's a reason someone came up with this eSATA stuff...

However, now I'm stuck as the system does not appear to detect the drive 
when I connect the firewire cable and turn it on.

I've followed some of the suggestions to check the drive status like
"fdisk -l" but this only shows the drives already installed in the system
"tail -f /var/log/dmesg" shows no new messages when the drive is 
connected/powered on


So I'm at a loss as to what else I should be doing to get Firewire to 
work and will appreciate any help on this.


Thanks!




2 things jump out:
	1. As has already been pointed out that is not a Centos Plus kernel. 
Did you reboot after installing the new kernel? (You have to reboot for 
a kernel update in order to be running the new kernel).
	2. 1 hour to copy 100GB sounds like a very good speed. Obviously the 
eSATA interface will be the fastest as it will the the same as having it 
plugged directly into the SATA controller. For reference I recently 
copied 73GB from an internal SATA drive to an internal (software) raid0 
array (made up of 2 SATA disks), and that took 1.5hours.

Re: [CentOS] conntrack-tools and Session syncing

Also: cat /proc/net/nf_conntrack


Okay, that was good (it is ip_conntrack, but never mind). Now I now that 
the kernel connection table does NOT get updated. Just have to find out 
why.



The doc says you must have kernel 2.6.18 or later. It looks like there
are some iptables features that you can use that will not allow this to
work. Are you in compliance with all of the dependencies listed in
http://conntrack-tools.netfilter.org/conntrackd.html ?


Yes, the libraries are installed. The kernel should meet the prerequisites:
CONFIG_NF_CONNTRACK=m: yes
CONFIG_NF_CONNTRACK_IPV4=m: no, did not find it, could not enable it
CONFIG_NETFILTER_NETLINK=m: yes,
CONFIG_NF_CT_NETLINK=m: yes, it is called NF_CONNTRACK_NETLINK=m
CONFIG_NF_CONNTRACK_EVENTS=y: yes

So only CONFIG_NF_CONNTRACK_IPV4 module is missing, but I thought that 
connection tracking would not work at all (even on just one netfilter 
instance) if a dedicated module für IPv4 additionally to the general 
NF_CONNTRACK module would really be needed.


Is there a debug mode for conntrackd where I can get more verbose logging 
to find out why conntrackd does not update the kernel connection table? 
Docs do not mention a debug mode, but maybe ...


By the way, when committing manually (conntrackd -c) I get the following 
entries in the log:

[Tue Aug 12 12:51:49 2008] (pid=22668) [notice] Committed 139 new entries

Why can not all cache entries be committed? I did not find much about this. 
My kernel is a 2.6.18-92.1.6.el5 (CentOS 5).


Thanks for your help.

If that is the output, you are not running the centosplus kernel. It
is supposed to be:

Linux 2.6.18-92.1.10.el5.centos.plus

(See http://www.centos.org/modules/newbb/viewtopic.php?topic_id=15788&forum=37 )

Unfortunately this didn't work. Although I could see a whole lot of MIB's
now, Cacti still doesn't graph the network interface

The error I'm getting is :

 This
data query returned 0 rows, perhaps there was a problem executing this data
query. You can run this data query in debug
modeto
get more information.


When I enable debug mode for the interface, this is all I get:

[CentOS] Help setting up external drive via Firewire

[Noob Centos Admin]

I got a WD 1TB My Book with eSATA/USB/Firewire400 connectivity to backup
data on a client Centos 5.1 machine.

USB 2.0 works fine out of the box but is rather slow, Nautilus predicts
about 1+ hour to fully backup just one day's worth of data or about 100GB.

So I was hoping Firewire would be faster, which is why we got the version
with all 3 interfaces to experiment with first.

Following the suggestions given to another user here
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=15767&forum=37

I updated the system's kernel to the CentoPlus
[EMAIL PROTECTED] ~]$ uname -s -r
Linux 2.6.18-92.1.10.el5

After a reboot, everything appears to work as expected, with the
motherboard's TI Firewire controller detected
[EMAIL PROTECTED] ~]# lspci | grep 1394
04:07.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000
Controller (PHY/Link)

However, now I'm stuck as the system does not appear to detect the drive
when I connect the firewire cable and turn it on.

"fdisk -l" but this only shows the drives already installed in the system
"tail -f /var/log/dmesg" shows no new messages when the drive is

So I'm at a loss as to what else I should be doing to get Firewire to work
and will appreciate any help on this.
