[CentOS] Centos 5: e1000 question

[Mogens Kjaer]

I have a machine running Centos 5, x86_64.

It has an Intel NIC:

# lspci
15:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet 
Controller (Fiber) (rev 06)


The machine has two dualcore cpus.

If I look at /proc/interrupts I get:

   CPU0   CPU1   CPU2   CPU3
  0:  144873228  220741831  173615012  220733357IO-APIC-edge  timer

Yes, they threw the example files into the doc directory.

How about the doc section on www.centos.org?

Why would you expect that rebuilding it will make it work for SELinux ?

[CentOS] Static linking against glibc

[Anand Buddhdev]

I'm building an RPM of a DNS server called NSD on CentOS 4.4. I'm going to 
be using it for some heavy-duty DNS traffic, so I want to minimise its 
dependencies on external libraries. I have therefore attempted to link it 
statically.

The package does build, and even runs fine. However, during the build 
process, gcc emits warnings like these:

nsd.o(.text+0xfba): In function `main':
: warning: Using 'getpwnam' in statically linked applications requires at 
runtime the shared libraries from the glibc version used for linking

My understanding of this is because glibc uses dlopen to load other shared 
objects at runtime. I therefore need a Requires: line in the RPM which 
requires glibc-2.3.4-2.36, or whatever version I used to build nsd.

Now, what I want to ask is: if the version of glibc is upgraded to say 
2.3.4-2.48, what happens? What do the numbers after the version number 
mean (2.48) and what effect will that have on packages which are 
statically linked against glibc?

Another question which has occured to me is this: NSD also uses other 
libraries, such as openssl. Is there any way to know if any of the 
openssl libraries use dlopen to load in other shared objects? If they do, 
then it introduces dependencies that I may not be aware of, and doing 
static linking wouldn't be as beneficial as I first thought it would be.

Comments from experienced developers will be most appreciated.

Rebuilding the code won't solve the problem. You'll have to modify the
selinux rules so that these actions are allowed. For Centos5 and rhel5
this is pretty easy.

1. Enable selinux in permissive mode, and capture the selinux error
messages. They'll likely be in /var/log/audit/audit.log or
/var/log/messages
2. Run audit2allow -i selinux.log -M localpolicy
3. Next you load the module you just created with 'semodule -i localpolicy.pp'

Lather, rinse, repeat.

Actually, I don't think this is a very good idea (I know it is suggested
in upstream documentation). For instance, suppose that clamav is tagged
as, say 'bin_t', and executing clamav was rejected. The above will
usually add a allow rule for executing bin_t binaries for the context of
the caller. This obviously punches a big hole in a policy if it does not
allow such thing.

Make your own policy modules for local policy (you could create a start
with command (2)), but add and check rules and contexts manually.
audit2allow is a nice tool to see what was denied, but its output should
not be copied verbatim.

Your terms are confusing. Did you install php the first time via rpm?
If so, that is not 'compiling'.  RPM does not modify code on the
system, it either installs or replaces files. It is not used to alter
build options.


download the source and run ./configure again ? what about yum ? it was
great if yum or
rpmbuild could save the current config and just add the new extensions.


Still not sure what you're looking at or what you're attempting to do

Eh, call me lazy... I didn't want this to become a 'how to create
selinux policy modules' discussion, so I paraphrased the upstream
documentation. It may not be the most secure method (Obviously) but it
is the same support upstreams users are paying to get, at least at the
tier 1 support level.

Re: [CentOS] bind on centos 5

I'm having a little trouble to get this working on my box.

I have two domains I need to host on my machine. I have named
starting, but I'm having trouble getting it to do the lookups for the
two domains. The caching-nameserver is working.

I removed all the bind stuff and reinstalled it all, minus the chroot
because I was having problems getting bind to start at all with that
there.

I can post my named.conf file as well as my two domain files if
someone could give me a hand.

thanks.

[CentOS] Nautilus displays open document files of OpenOffice.org2 as ZIP files

[Boris Folgmann]

Hi,

the openoffice.org2 RPMs for CentOS 4.5 work very well, but there seems to 
be some integration missing. OO2 saves all files in the new Open Document 
Format, e.g. .ods, which is displayed by nautilus as a simple ZIP file 
(which isn't that wrong).

But this means that you can't open the files directly by using a double click.

/usr/bin/file seems to have the same problem, it doesn't know that data 
type exactly, too. file reports it as "Zip archive data, at least v2.0 to 
extract"


Does anybody know if it's planned to improve the integration, so that it 
works like for the old OpenOffice.org?

[CentOS] logwatch reports not benig emailed

[Kanwar Ranbir Sandhu]

Hello,

I have a couple of CentOS 5 servers, and third running in a FC6 domU.
I've configured postfix on those servers to not deliver any email to the
local system, but to instead relay mail to an internal mail server.  I
also set up /etc/aliases to send all mail to root to me, ksandhu.

I can send mail on the command line, and I get it at my email address,
delivered to the internal mail server: great!  But, every night when
logwatch runs, the damned reports never make it to my mailbox.  What's
worse is that I can manually run logwatch (logwatch --mailto root), and
I get the report in my mailbox!  All CentOS 5 servers are exhibiting the
same behaviour.

I've setup postfix like I always have.  CentOS 4 servers with the same
config are sending their logwatch reports properly.

I've tried explicitly setting the path to sendmail
in /etc/logwatch/conf/logwatch.conf:

mailer = "/usr/sbin/sendmail -t"

but, it hasn't helped.

Does anyone have any ideas?  I must be missing something obvious.

Regards,

Ranbir

[CentOS] Module install: warning about weak-updates?

Hi all,

I'm wondering about the warnings I got below on an updated CentOS5 box:

$ sudo rpm -ivh zaptel-modules-1.2.18-21.2664.2.6.18_8.1.6.el5.lc.i686.rpm

WARNING: Can't read module

What is causing these warnings and how can I prevent them?

Thanks for any pointers.

[CentOS] iptables rule (MAC filtering)

[Jordi Espasa Clofent]

Hi all,

I've a CentOS box which as two NIC; this box is also a router for LAN 
subnet:



| eth0 (external) 172.0.0.1|
| eth1 (internal) 192.168.1.1 |

  |
   LAN clients (192.168.1.2+)

I want to allow http acces only for two LAN boxes; an only http access, 
which means that others protocols as smtp, pop3, imap and so on will be 
permited. The rest of LAN boxes will be redirected to a local http 
service (192.168.1.1:80)


I think the best way is creating a iptables rules based on MAC address. 
So, the rules I've made are:


iptables -t nat -A PREROUTING -p tcp -s 192.168.1.0/24 -m mac 
--mac-source ! xx:xx:xx:xx:xx:xx --dport 80 -j DNAT --to-destination 
192.168.1.1:80


iptables -t nat -A PREROUTING -p tcp -s 192.168.1.0/24 -m mac 
--mac-source ! xx:xx:xx:xx:xx:xx --dport 80 -j DNAT --to-destination 
192.168.1.1:80


Please, note the exclamation symbol, which means a logical negation.

But it seems doesn't work correctly: all the LAN clients can suffer the web.

Yes, but ORing the two, all clients should have gone to the local http
service.

The best thing, in this case, is to use chains:

iptables -t nat -N twoboxen
iptables -t nat -N others

iptables -t nat -A PREROUTING --mac-source aa -j twoboxen
iptables -t nat -A PREROUTING --mac-source bb -j twoboxen

Thanks for your reply Dag.

Sorry for not responding sooner.  I was hoping to report on a fix for
the xen kernel but haven't yet had time to resolve that problem.

I got suspend to ram and suspend to disk working on May 27 but didn't
follow up since no one on this list seemed interested in this thread.

The graphical card was never an issue for me; the machine wouldn't
suspend in the first place.

I've included some notes for those who might have similar troubles.


SUMMARY:
- I knew about adding "acpi_sleep=s3_bios" to the kernel boot parameters.
- Using that, and "resume=/dev/sda2" (my swap partition) did the trick.
- But not for the xen kernel.
- Reference information in  
  http://thinkwiki.org/wiki/Swsusp
- A quick way to tell if it's going to work is to run
"lshal |grep suspend"
  ...
  power_management.can_suspend_to_disk = true  (bool)
  power_management.can_suspend_to_ram = true  (bool)
  power_management.can_suspend = true  (bool)
- The kernel provided by CentOS does support suspend to ram and
  suspend to disk.


DETAILS:

- When using GNOME to suspend or hibernate the computer it points to
  the following website, implying that the feature isn't available in
  the kernel.

  http://live.gnome.org/GnomePowerManager/FAQ

Entry:
8. Why does GNOME Power Manager not let me suspend or hibernate?
   Says:

% lshal | grep suspen
  ...
  power_management.can_suspend_to_disk = false  (bool)
  power_management.can_suspend_to_ram = true  (bool)
  power_management.can_suspend = true  (bool)


- Get and install the kernel source:
http://wiki.centos.org/HowTos/I_need_the_Kernel_Source
% yum list 'kernel*'
  ...
% yum install 'kernel*'
...
Total download size: 63 M

http://mirror.centos.org/centos/5/os/SRPMS/
Got kernel-2.6.18-8.el5.src.rpm from above and installed it.

rpmbuild -bp --target i686 kernel-2.6.spec


That produces a config file in
  /usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i686/.config


- It looks like the kernel does support the suspend.
  This can be viewed in the config file

% grep SUSPEND .config
CONFIG_SOFTWARE_SUSPEND=y
CONFIG_SUSPEND_SMP=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_USB_SUSPEND is not set

  It can also be viewed via the kernel config gui
% make xconfig &


- This ThinkWiki page provides the answer

http://thinkwiki.org/wiki/Swsusp
...
NOTE!
For some people suspending did not work if resume_partition was
specified in the kernel config. In such case specify the resume
partition as a kernel parameter instead.


- All that's required is to add this to the boot parameters:
  resume=/dev/resume_partition  (swap partition)
  resume=/dev/sda2


- Add this to grub and boot from this config.
  Added to grub:
title CentOS (2.6.18-8.1.4.el5 hibernate)
root (hd0,0)
kernel /vmlinuz-2.6.18-8.1.4.el5 ro root=LABEL=/ rhgb 
resume=/dev/sda2 acpi_sleep=s3_bios quiet
initrd /initrd-2.6.18-8.1.4.el5.img


- Now lshal looks better
  % lshal | ma susp disk
...
power_management.can_suspend_to_disk = true (bool)
power_management.can_suspend_to_ram = true  (bool)
power_management.can_suspend = true  (bool)

- It can now suspend to ram or disk using gnome or these commands:

  To suspend to ram:
echo mem > /sys/power/state

  To suspend to disk:
echo disk > /sys/power/state


- ThinkWiki is an excellent resource that I've known about for quite
  some time.
  Why didn't I notice the note on the Swsusp page earlier?

  I've tried the suggestions on this page in the past but with kernels
  that didn't support them.  I still can't get it working with the xen
  kernel.


Thanks again Dag.

Thanks also to the CentOS team and this mailing list for their

Your terms are confusing. Did you install php the first time via rpm?
If so, that is not 'compiling'.  RPM does not modify code on the
system, it either installs or replaces files. It is not used to alter
build options.


download the source and run ./configure again ? what about yum ? it was
great if yum or

RPM won't help you with this. The only way you could use it to solve

Re: [CentOS] iptables rule (MAC filtering)

It's understandable example; so, it's enough.

IP addresses are very easy to change. The idea is only a two concrete

Yes, but ORing the two, all clients should have gone to the local http

iptables -t nat -A twoboxen -j ACCEPT
iptables -t nat -A others -p tcp --dport 80 -j REDIRECT


I think this is a "large" solution. Two iptables code lines should be 
enough. I've modified the lines:

You could use the PHP SPEC file to build your own rpm with your own
options, this way you can keep the version changes of the package
within th package manager (RPM).

Two of these for each of the two hosts? That's what I don't understand.

Let's suppose you have host A, B, C, D, E, and want only A and B to have
access to the web. So, the rules would look like:

1. iptables -t nat -A PREROUTING -p tcp -i eth1 -m mac --mac-source ! 
 mac(host A) --dport 80 -j DNAT --to-destination 192.168.1.1:80
2. iptables -t nat -A PREROUTING -p tcp -i eth1 -m mac --mac-source ! 
 mac(host B) --dport 80 -j DNAT --to-destination 192.168.1.1:80

Ditto for -A OUTPUT.

So, what happens when C, D or E send a packet? They don't match any mac
address, so they will be DNAT'ed to 192.168.1.1.

What about A? It doesn't match rule 1, but it matches rule 2, so it will
be DNAT'ed also.

And host B? It matches rule 1, so it is DNAT'ed.

Thus the use of chains, to send each host to the proper chain and there
do the work (dnat or don't dnat).

Ok. It's a typo: I wanted to write 172.26.0.0/24 :P

Yes, of course. Almost for advanced users or sysadmins. But in this case 
the LAN clients are Win machines with "normal" users. I think they don't 
know even what's a MAC address.



Two of these for each of the two hosts? That's what I don't understand.

Let's suppose you have host A, B, C, D, E, and want only A and B to have

[CentOS] How can I set NIC duplex before installation?

[John Horne]

Hello,

I have installed CentOS 5 onto a server this afternoon using NFS. The
NFS 'server' has a 100Mb/full-duplex interface, the server I installed
CentOS on to has 4 x 100Mb interfaces. However, the installation was
painfully slow to start with, and by using ctrl-alt-f2/f4/f5 I could see
that contact with the NFS server was intermitently failing. Soon after
some of the packages had installed the 'ethtool' command was then
available, and I could see that the (installation) server NIC had been
set to 100Mb but at half-duplex. This was causing numerous collisions
and errors on the NIC interface. As soon as I reset the NIC to
full-duplex (via ctrl-alt-f2 and using ethtool), then the installation
speeded up and seemed to cause no more errors.

My question is, how can I tell anaconda to set the NIC interface options
such as speed and duplex? I have another server to install which has 2 x
gigabit NICs and 2 x 100MB NIC's. My concern is that anaconda will again
use wrong NIC parameters, and the installation will again be very slow.
Surely it is possible to set the NIC options?



John.

On the boot line, use the following to set your first ethernet interface to use
100Mb/s full-duplex ethernet:

eth0_ethtool="autoneg=off speed=100 duplex=full"

Okay, that seems easy enough :-) Thanks.
However, is the anaconda NIC ordering the same as those listed by the
bios? For a mixed NIC server it could be important.

not always.I've got some Intel SE7501WV2 based dual xeon servers 
which have dual intel pro1000 NICs onboard...the BIOS, MS Windows, 
etc think the one labled '0' on the outside is in fact the first port, 
but RHEL2.1 and RHEL3 at least thought that they were swapped, and that 
eth0 was the port labeled '1', while eth1 is the port labeled '0'.


I know I could probably force the issue, instead, I just live with it.   
those servers have been SO reliable I've never had to dink with them.

Hmm, well I guess I could use the bios ordering to set the first NIC
options, and if anaconda thinks anything different then just restart the
installation using whatever it (anaconda) thinks is the first NIC. A
pain, but basically it's either going to be 100Mb or 1000Mb! :-)

Once the installation has done, we tend to bond the interfaces together
(using active-backup mode). I have found that by creating simple udev
rules, the NIC ordering no longer changes over reboots. I can then
correctly set the NIC options in the ifcfg-ethx files.

Fantastic - thanks for your explanation and the SRPM James. For the record,
James appears to be completely correct and his SRPM fixes my problems here
on CentOS 4.5 - woohoo!

His patch also applies cleanly to the current CentOS 5 package and fixes 
the problem there as well - a patched SRPM is available here for anyone else
experiencing the problem:
 
  http://www.openfusion.com.au/labs/dist/OpenIPMI-2.0.6-5.of.el5.3a.src.rpm

(and binary packages are in http://www.openfusion.com.au/mrepo/).

Cheers,
Gavin

I've also reported the problem upstream:
