1. Get list of interfaces that are up:

Then load the module:
modprobe forcedeth

Then check interface status again to see which has come up (if any):
ip l l

If no interface has come up, post the error on screen (if any), then 
check the logs to see if any errors are reported and post them back here 
as well.


(not sure if on C7 immediately initiates a DHCP request when the 
interface comes up)


Check if interface has an IP address:
ip a l

If no IP address, then request one via DHCP:
dhclient 

Browse the net... Done!

If no DHCP server on network, then set one manually as indicated below:
ip a a 1.1.1.1/24

then bring it up:
ip l set  up

then add a default route:
ip r a 0/0 via

Subject: [CentOS-announce] ABRT for CentOS Linux is now live
Message-ID: <5469eedc.4050...@centos.org>
Content-Type: text/plain; charset=utf-8


ABRT is a collection of scripts that makes it easier to report bugs and
crashes in various components of the distribution to a central server.
Metadata from this allows developers and upstream projects to evaluate
their priority chain, and also get crucial information on why their
software might not be performing as expected on CentOS Linux.

This information is sent to the server in a json format text file, the
contents of which will never contain private date. The entire
specification for this report format is available at :
https://github.com/abrt/faf/wiki/uReport and I encourage everyone to
read it once, so as to build confidence in the process.


You can enable ABRT reporting by running:
/usr/sbin/abrt-auto-reporting enabled

this script is provided by the 'abrt' rpm package.


More details on ABRT on CentOS are available on the CentOS wiki at
http://wiki.centos.org/TipsAndTricks/ABRT ; The entire ABRT
documentation is available online at :
http://abrt.readthedocs.org/en/latest/ - this includes both user and
developer information.

For those looking to get started with hacking on ABRT, start by reading
through the advanced usage examples at :
http://abrt.readthedocs.org/en/latest/examples.html


The reports posted by CentOS machines will currently land at the Fedora
Project hosted retrace server at : https://retrace.fedoraproject.org/


For any problems or issues with the abrt code included in CentOS Linux,
or for any problems associated with abrt user experience on CentOS Linux
: please post reports at http://bugs.centos.org/ by selecting the right
Distribution version and component as 'abrt'.

All other conversations around abrt on CentOS Linux should goto the
CentOS-devel mailing list ( http://lists.centos.org/ ).

[CentOS] Fwd: Centos and logs

[Alan Holt]

Hello,

may be anyone familiar with some tool for viewing logs.
I mean web-interface based, simple solution.

I have developers, and I can't give them access to my Centos servers, but
they want to see logs of Apache. I want to give them address like
172.17.17.21/logs and they will be able to watch logs of Apache in browser.

I was looking a lot for something like this, but didn't find.
Alex.

you say 'servers': plural, which leads me to think you're doing
load balancing or otherwise have multiple servers which seems
like another layer to consider for your puzzle.

I would consider something like splunk (or more likely one of the
free alternatives) and a setup like:

(users) ---public interface --> [webserver] -private interface --\
-- for logs-->[splunk/log collector]<(developers)

and make sure there are acls/firewall rules in place to just allow
your developers access (http logs may well include some data that
you don't want to get out to the public, like if someone implements a
cgi as a get instead of a post but has sensitive data included)

[CentOS] Centos 7 Nvidia openGL breaks vncserver

[Stan Cruise]

Bare metal Centos 6.5, vncserver running, client able to connect with 
perfect resolution. Nvidia GT240, driver 331.49.


Upgrade to Centos 7 with nouveau basic driver, all still works fine. 
Resolution poor on wire connected monitor, but perfect on vnc client 
session (1920x1080).


Upgrade Nvidia driver via elrepo. 340.58; removed nouveau via 'Software' 
manager. Excellent wired monitor resolution.


But >> Client vnc connect receives the dreaded 'oh no, something has .'

Backed out Nvidia  340.58, back to nouveau, client vnc works again. Also 
tried 304 driver (only other one in elrepo for el7) - same problem.


Research seems to indicate that openGL does not play well with vnc. I 
cannot see any solutions posted as yet.


So, what are my options?

Maybe change out the video card for AMD? I cannot know if the Catalyst 
driver will work, but there is a much more active and extensive open 
driver community, which could work better than nouveau?


And I noted the Linus 'salute' to Nvidia... Good timing.

If it's of any help to you I have just restored the last 331.xx series
driver (331.89) to the elrepo repository. It's currently syncing and
should show up on the mirrors shortly. At least now you should be able
to make a like for like driver comparison with your el6 install.

Re: [CentOS] Fwd: Centos and logs

[Jeremy Hoel]

With splunk you get 500mb/day free.  So you can collect logs with rsyslog,
drop the stuff you don't want to see ever and then forward the rest to
splunk.  This could help save on license issues.

You also have tools like greylog.  It can be fed from logstash also and is
very impressive.  ELK, as Keith mentioned, is awesome.. as is a tool called
ELSA.  Lots of ways to look at logs via the web.  the harder part is
knowing what you are looking for, field extraction and correlation.

Are you maybe trying to run Gnome3 through vnc by any chance? Because
Gnome3 requires 3D acceleration, and I'm not sure that nvidia driver
would simulate 3D stuff in software (nouveau should fall back to mesa
in case hardware acceleration fails --- typical of a vnc session).

So my suggestion is to try KDE or XFCE or LXDE or Mate or... any other
DE which doesn't require 3D features to work. Such DE should work
through vnc using nvidia driver no problem --- the only exception is
Gnome3.

You don't want to guess which driver you need. Use the nvidia-detect
utility from elrepo, it will tell you which driver to install.

My choice would be to try a less demanding DE first.

Catalyst driver has always been a pure gamble for me (i.e. worked 50%
of time, supported 50% of video cards, and could be installed on 50%
distributions... or so...). The open-source radeon driver is much better
supported.

That said, the radeon community is not any more active or more extensive
than the nouveau community. It's just that AMD has released the specs
for their cards, so they have a much easier job of maintaining the
radeon driver than the nouveau community (which basically needs to RE
everything from scratch).
 
HTH, :-)

You could use NFS, exportfs the apache log directory to 127.0.0.1 only,
make a directory somewhere accessible to the developers outside the root of the 
server
and mount the apache log directory to that dir READONLY.

Alternatively you can change the log directory location in http.conf to
somewhere the developers can access it but outside the root of the server. 
Since apache AND the developers must be able to access it this should be no 
problem.

Anthony K's suggestions will not be persistent (won't last a

@Anthony,
Thanks for sharing your examples.
I've gotten spoiled by using the "ip addr show" shortcut of "ip a s".  So
much so that I try to do "ip l s" for "ip link show", which doesn't work.
Given the error message: Not enough information: "dev" argument is
required. I figure ip tools thinks I'm attempting to set something on the
interface.  Anyhow, your "ip l l" shortcut appears (see my manpage comment
below) to evaluate to "ip link list", which is awesome!  Shortcuts for the
win.

On a CentOS 6.6 system per the ip manpage, it seems that "list" is
undocumented for link and addr.

(Certainly correct me if I'm wrong ... I did find a TLDP page with an
example of "ip link list", so it's known by some.)

​This issue has been discussed over at the freeipa-users list. The
solution, for now, is to build jackson-jaxrs-json-provider yourself.

Thanks Mike.

I use Ubuntu on the laptop and in the manpage for the ip command it has 
the following:


COMMAND
   ...*As a rule, it is possible to add,**
**   delete and **show (or list )**objects, but some objects do not 
allow all**

**   of these operations or have some additional commands.* ...

Seems to be vaguely documented - I can see how *(or list )* part can be 
misleading as you might think they are just saying that show 
_will_list_  and not necessary that *list* can be substituted for *show* 
- it's all in the wording!


Oddly, the man page for ip (iproute-2.6.18-13.el5) on CentOS 5 is way 
more comprehensive (it has way more examples on where list can be used) 
than that on Ubuntu 14.04.1 with iproute-3.12.0-2! But then, Ubuntu has 
a man page for each ip object:


$ man ip-
ip-address  ip-monitor  ip-ntable   ip-tunnel
ip-addrlabelip-mroute   ip-routeip-xfrm
ip-l2tp ip-neighbourip-rule
ip-link ip-netconf  ip-tcp_metrics
ip-maddress ip-netnsip-token

Subject: [CentOS-announce] ABRT for CentOS Linux is now live
Message-ID: <5469eedc.4050...@centos.org>
Content-Type: text/plain; charset=utf-8


ABRT is a collection of scripts that makes it easier to report bugs and
crashes in various components of the distribution to a central server.
Metadata from this allows developers and upstream projects to evaluate
their priority chain, and also get crucial information on why their
software might not be performing as expected on CentOS Linux.

This information is sent to the server in a json format text file, the
contents of which will never contain private date. The entire
specification for this report format is available at :
https://github.com/abrt/faf/wiki/uReport and I encourage everyone to
read it once, so as to build confidence in the process.


You can enable ABRT reporting by running:
/usr/sbin/abrt-auto-reporting enabled

this script is provided by the 'abrt' rpm package.


More details on ABRT on CentOS are available on the CentOS wiki at
http://wiki.centos.org/TipsAndTricks/ABRT ; The entire ABRT
documentation is available online at :
http://abrt.readthedocs.org/en/latest/ - this includes both user and
developer information.

For those looking to get started with hacking on ABRT, start by reading
through the advanced usage examples at :
http://abrt.readthedocs.org/en/latest/examples.html


The reports posted by CentOS machines will currently land at the Fedora
Project hosted retrace server at : https://retrace.fedoraproject.org/


For any problems or issues with the abrt code included in CentOS Linux,
or for any problems associated with abrt user experience on CentOS Linux
: please post reports at http://bugs.centos.org/ by selecting the right
Distribution version and component as 'abrt'.

All other conversations around abrt on CentOS Linux should goto the
CentOS-devel mailing list ( http://lists.centos.org/ ).

regards,


Thanks KB and anyone else involved.  I was one of the ones that first 
complained asking "Why are you even distributing this tool that will only 
send reports to RH, but RH rejects them."

[CentOS] Centos 7 Nvidia openGL breaks vncserver

[Stan Cruise]

On 18/11/14 5:42 MT, Stan Cruise wrote:

Well I found the Nvidia 331.89 dvr and kmod on the elrepo site; installed OK.
Reboot, works fine on wired monitor. Still same problem on vnc client.

Another post on this forum suggested to try the Nvidia driver download directly 
from Nvidia. Better still, I actually had the original
NVIDIA-Linux-x86_64-331.49.run file which worked on Centos 6.5. I did a manual 
install (run level 3 etc). It installed fine.
Same problem though.

So, at this point it seems associated with the new C7.

Either we can hope for a fix in C7, or I will have to try a non-Nvidia card.

Some Background:
I learned how to get tigervnc-server working on C7 thru
many failed attempts on VMs. I found if I did the following steps exactly, it 
works. There may
be some variability in the sequence that works but I did not try all 
permutations.
But, if I don't do this list exactly, then I would also get the 'oh no ... 
error at the client.
All this to note that getting this to work on C7 with systemd/systemctl is 
quite sensitive.

Steps:
Create new VM on hyper-v or kvm (both work fine)
Fresh 'DVD' install of C7 1406: both iso file and straight DVD install tried on 
different VMs.
Update software via Software app
Install tigervnc-server
copy usr/lib/systemd/system/vncserver@:.service to 
usr/lib/systemd/system/vncserver@:x.service; modified @:x file with
user info
systemctl enable vncserver@:x.service
verify that the vncserver@:x.service symlink is in 
/etc/systemd/system/multi-user.target.wants/
systemctl start vncserver@:x.service

Then go to client and start up vnc .

If it's of any help to you I have just restored the last 331.xx series
driver (331.89) to the elrepo repository. It's currently syncing and
should show up on the mirrors shortly. At least now you should be able
to make a like for like driver comparison with your el6 install.

Gnome3 it is. I naively figured that this was the 'default' but alas it 
is a selection which I did make.


I had seen hints of this in discussions elsewhere and did try KDE, but 
that is tough sledding on C7, and I got impatient. I should have stuck 
it out. (KDE has a bug on vncserver enable and creates the wrong symlink 
in /etc. At least it is different and requires work to get it right).


Mate is my next try.

I did try the nvidia-detect and it did say to use 340.58.

Thanks again for helping me converge. I will be silent for a bit to try 
out different DEs.

Are you maybe trying to run Gnome3 through vnc by any chance? Because
Gnome3 requires 3D acceleration, and I'm not sure that nvidia driver
would simulate 3D stuff in software (nouveau should fall back to mesa
in case hardware acceleration fails --- typical of a vnc session).

So my suggestion is to try KDE or XFCE or LXDE or Mate or... any other
DE which doesn't require 3D features to work. Such DE should work
through vnc using nvidia driver no problem --- the only exception is
Gnome3.

You don't want to guess which driver you need. Use the nvidia-detect
utility from elrepo, it will tell you which driver to install.

Catalyst driver has always been a pure gamble for me (i.e. worked 50%
of time, supported 50% of video cards, and could be installed on 50%
distributions... or so...). The open-source radeon driver is much better
supported.

That said, the radeon community is not any more active or more extensive
than the nouveau community. It's just that AMD has released the specs
for their cards, so they have a much easier job of maintaining the
radeon driver than the nouveau community (which basically needs to RE
everything from scratch).
 
HTH, :-)

yes, you can, but it's true that with the massive anaconda/storage
section rewrite, it's not as obvious as it was with anaconda in CentOS 6.
I've no screenshot/howto to show, but do you think that it's something
that's worth blogging about ?

PS : just a quick "centos 7 raid 1" google search shows some
