Re: [CentOS] Suddenly increased my hard disk

2016-04-18 Thread Chandran Manikandan
Hi Geleem,
Please have a look below of my result.

For my system shows like below.
df -h

Filesystem  Size  Used Avail Use% Mounted on
/dev/sda2   909G  576G  287G  67% /
tmpfs   3.9G 0  3.9G   0% /dev/shm

/dev/sdb1   916G  382G  488G  44% /bkhdd

First hard disk /dev/sda
Second hard disk /dev/sdb

The problem is in first hard disk show above size but my email box folders
having below result.

du -hs /*
8.0K/backup
7.5M/bin

/bkhdd is mount in /dev/sdb

/ is mount in /dev/sda

But the size is not match in /dev/sda

I am running Centos 6.5 32 bit with CLI Mode.
How do i check the cache size in this mode.

Bump.

Please answer the original question (again) CentOS folks.

Where are we with getting the RHEL version of Chromium available for CentOS?

There should be no technical reason why we can't get a working, up to date,
and therefore secure version of chromium running on CentOS 6.7!!

ok. look at size from a diff perspective.

in a virtual terminal, enter df -H, then df -h, followed by df -k.

are you sizes closer with "-k" ?

if in wonder, open second v-term, enter man df to get an understanding
of how block size and rounding cause interesting results.

same applies to du.

neither have a -b to see actual bytes, which i believe is because disk
usage is by blocks, not bytes.

Unfortunately, I have neither the time, nor expertise to partake in such a
project.

Since Mr. Hughes had already gotten earlier versions of chromium to build
under CentOS 6 (c.f. http://people.centos.org/hughesjr/chromium/6/), and he
indicated it was merely a matter of getting RHEL to give permission for him
to redistribute it more "formally" to the community, I was hoping progress
had been made with that.

Have you, as the CentOS project lead ever asked RedHat if they can make
their version of Chromium for CentOS 6 available for us? If not, can you
please?

Since this seems to come up periodically, there is a demand for it out
there.

I wouldn't worry too much about this until it actually happens.  It
pretty much means that Google is not willing to support running Chrome
on CentOS, but then they never did to begin with anyways, it just so
happens that the statically-built RPM for Fedora runs on CentOS 7
without issue.  It's a scary and pretty much meaningless message.

Eventually Chrome will likely require some newer version of a library
than is available on CentOS 7, this happened in 6 a few years ago, and
when that happens hopefully someone can work on a solution to fix it
(possibly back-porting the newer version of said library).

Right, Johnny Hughes (I think) used to build it, but IIRC he had to stop
for reasons that you can find by searching this mailing list.

Note that I'm personally not interested in getting chrome to work for
CentOS 6, but I have a vested interest in keeping it working in 7, so
when the time comes I'll very likely find a solution myself and share it.

I think Richard Lloyd had (has?) versions that work, but are usually a bit
old.  
At present, CentOS-7 works with the rpm for Fedora on Google's site. I
don't think RedHat had their own official rpm for either RHEL-6 or 7, did
(do) they?

I eventually updated to CentOS-7 on my main home machine, so I haven't kept
up.

is there someone else on here who can help ? I think if we can
demonstrate some traction, it would go a long way in both the upstream
engagement and the conversation with Red Hat - since we can then

Johnny, can you perhaps quantify the effort a bit ? And if you need
help what sort of help you might need for this ? I suspect a large
part of that is just going to be time in day.

This is just a script that pulls some libraries from a Fedora repo.
Unfortunately that approach won't hold muster with security auditors .

We have over 150 workstations still on CO 6.7 while we are stuck dealing

Thanks. I imagine (hope?) there shouldn't be too much effort to get this to
work, since it's already been done upstream. RedHat continues to push out
updates even. E.g. https://rhn.redhat.com/errata/RHSA-2016-0638.html

that looks like Supplementary content - we've never had that before.

what we might need to do here is work the upstream beyond Red Hat
where this works done, that makes it Supplementary content and not
completely open source. Do we atleast know at this point what that
might be ?

I suspect it has to do with their "pepperflash" flash plugin.

Clearly flash is on the way out, so any support for it is not necessary.

Re: [CentOS] VPN suggestions centos 6, 7

2016-04-18 Thread david





Folks

I would like to have my windows 7 laptop communicate with my home 
server via a VPN, in such a way that it appears to be "inside" my 
home network.  It should not only let me appear to be at home for 
any external query, but also let me access my computers inside my home.


I already have this working using M$'s PPTP using my home Centos 6 
gateway/router as the PoPToP server.  However, I am concerned about 
the privacy/security of such a connection.


I have seen discussions of OpenVPN, OpenSwan, LibreVPN, StrongSwan 
(and probably others I haven't noted).  I'd be interested in hearing 
from anyone who wishes to comment about which to use, with the 
following requirements:


1)  As noted, it should be secure (anti NSA?)
2)  Works on Centos 6 and Centos 7 and Windows 7 (and for the 
future, Windows 10)

3)  Can be set up on the server with command line interfaces only (no GUI)

And, should not be a nightmare to set up.

Any thoughts?

David


FOLLOWUP & REPORT

I had lots of suggestions, and the most persuasive was to try 
OpenVPN.  I already had a CA working, so issuing certificates was 
easy.  The HOW-TO guides were less helpful than I could hope, but 
comparing several of them, applying common sense, and trying things 
out, I arrived at a dead-end.  Here's essentially what happened:


- None of the HOW-TOs were very clear about the need to add some 
attributes to a certificate, keyUsage and extendedKeyUsage.  They had 
different values for server and client.  OpenSSL documentation was a 
big vague on how to add them, but I think I did - the print out of 
the entity certificates showed the values.  The attempt to connect 
failed.  The client log is below.  I think it's complaining that the 
CA certificate doesn't have the ke Usage extension, which makes no 
sense to me.  Such an extension should be in the end-entity 
certificate, not the CA's, unless I'm wrong.  I checked the server 
and really think that the certificates are in the right place.

Re: [CentOS] VPN suggestions centos 6, 7

2016-04-18 Thread Paul Heinlein

On Mon, 18 Apr 2016, david wrote:


FOLLOWUP & REPORT

I had lots of suggestions, and the most persuasive was to try 
OpenVPN.  I already had a CA working, so issuing certificates was 
easy.  The HOW-TO guides were less helpful than I could hope, but 
comparing several of them, applying common sense, and trying things 
out, I arrived at a dead-end. Here's essentially what happened:


- None of the HOW-TOs were very clear about the need to add some attributes 
to a certificate, keyUsage and extendedKeyUsage.  They had different values 
for server and client.  OpenSSL documentation was a big vague on how to add 
them, but I think I did - the print out of the entity certificates showed the 
values.  The attempt to connect failed.  The client log is below.  I think 
it's complaining that the CA certificate doesn't have the ke Usage extension, 
which makes no sense to me.  Such an extension should be in the end-entity 
certificate, not the CA's, unless I'm wrong.  I checked the server and really 
think that the certificates are in the right place.


Here's how I managed that in my openssl.cnf file. Lots of bits ellided 
for clarity's sake:


### start ###
[ ca ]
default_ca = CA_default

[ CA_default ]
x509_extensions = server_cert

[ server_cert ]
basicConstraints=CA:FALSE
keyUsage = nonRepudiation, dataEncipherment, digitalSignature, keyEncipherment
extendedKeyUsage = serverAuth, clientAuth
nsCertType = server, client
### end ###

I think the nsCertType directive may be unnecessary these days, but I 
keep it around because it doesn't hurt anything.


The important bit is the extendedKeyUsage line; I'm pretty sure that 
an OpenVPN server needs the serverAuth extension. For instance, here 
is the X509 extensions configuration for a server used by EasyRSA:


  basicConstraints = CA:FALSE
  subjectKeyIdentifier = hash
  authorityKeyIdentifier = keyid,issuer:always
  extendedKeyUsage = serverAuth,clientAuth
  keyUsage = digitalSignature,keyEncipherment

You can ask openssl to tell you the purpose of a certificate:

[bash]$ openssl x509 -noout -purpose -in cert.pem  | grep SSL
SSL client : Yes
SSL client CA : No
SSL server : Yes
SSL server CA : No
Netscape SSL server : Yes
Netscape SSL server CA : No

Anyway, those are the extensions that should do away with these 
errors:

Francisco, OU=Certificate Authority, O=, CN=X.X.X

[CentOS] Machine-readble cloud-image list

2016-04-18 Thread Barak Korren
Hi there, I would like to write a script to download the CentOS
generic cloud images with the intention of making them eventually
available to oVirt users via the oVirt public Glance repository.

For that purpose I need to:
1. list the CentOS generic cloud images
2. list mirrors from where I could potentially download those images

I could try to parse the HTML here [1], but I'd rather just get the
lists from somewhere in some machine readble format if possible.

So is this information or parts of it available in some
machine-readable format somewhere?

[1]: http://cloud.centos.org/centos/7/images/

Thanks,
Barak

Have you gone to the CUPS page (http://localhost:631), to the printer, and
see if there's an option for grayscale only?

Unmount /bkhdd temporarily, and then run "du -hs /*" again.  One 
possibility is that you ran a backup while /dev/sdb1 was not mounted, 
and now you are consuming a bunch of space that you can't see because 
you've mounted another filesystem on top of it.

What commands?  I suggested that you look for deleted but open files using:

If you see any, you won't see their size.  All you'll really see is the

Do you see deleted files when you run the command above?

How is your switch configured?

The CentOS configuration you described would only work when you set 
GATEWAY, and when the port it's connected to has no VLANs configured for 
untagged access (or no VLANs that you need to access), and when the VLAN 
you DO need to access is tagged.


Are you providing access to one VLAN using tagged packets?

Thanks, I was kind of indulging my laziness, mentioned the command name
and assumed keen person will look up command usage him/herself. But on a

[CentOS] Is there a comprehensive documentation about CentOS7?

2016-04-18 Thread Shawn Fang
Hello everyone,
  I visited https://www.centos.org/docs/ and found no documentation
about CentOS7. Is the documentation about CentOS5 still suitable?

Thanks.

welcome and welcome to the 'lzpc', lazy people club'. charter members
excuse it as terse. B-)

being aware aware of your knowledge from your past post, i was a bit
amazed at your reply.

there is nothing wrong c&p. i am of habit when opportunity presents
itself. it lessens typos and need for thinking about spelling.

also good for adding a list member's name to my email address book. ;-)

in the early days I had a json file that had the details in there, but
it was dropped almost a year ago. If you file a requst at
bugs.centos.org and point me at it ( ideally assign the issue to me ), I
can work out the required bits.

What sort of info would you expect to see in this beyond
- filename
- date of last upates
- centos ver
- arch
- file format
- sha256um

regards

That's exactly the same thing that "ls -l /proc/*/fd/* | grep
'(deleted)'" will do. So how is lsof better, exactly?


lsof will show the sizes of the deleted files.

 lsof | grep deleted | sort -k7n

That's a reasonable G.D. answer.

The only problem is that on my system, the default output includes a
TID column that is present in only some of the lines, so the size
column is 8 for many lines and 7 for the others, so sort doesn't work
as expected unless you change lsof's output.

And you probably should "grep ' (deleted)$' unless you want to see
files like 
/home/gordon/.thunderbird/xxx.default/calendar-data/deleted.sqlite.

Still, I guess I learned one thing.

Re: [CentOS] 答复: How to configure VLAN in CentOS7

My guess would be that the switch isn't configured to give you access to 
VLAN 5 with tagged packets.  In that case, there's no need for you to 
configure eno1.5


Specifically what are you trying to accomplish by configuring a tagged 
VLAN interface?

[CentOS] 答复: 答复: How to configure VLAN in CentOS7

2016-04-18 Thread liyulei
Thank you again.

I am deploying Liberty Neutron, according the official document, there are
two NIC at least, but my physical machine has only one. Someone suggested me
I could create a vlan interface, then everything would be ok. Until now,
though I created the vlan interface, it can't attach to the Internet. 

Could other methods created virtual interface instead of vlan interface?

Thanks

Li yulei

Thanks for the quick response!

I've opened a request here: https://bugs.centos.org/view.php?id=10730,
but it does not seem I can assign it to you directly.

What about the mirror list? is that already available or does it need
to be requested as well?
