No one has mentioned Dconfig by Dag Wieers. I think it work really good.

[CentOS] package manager CentOS

[Raghu Narasimhan]

Hi folks,

I have some doubts with regards a Python module called paramiko (used to
automate ssh related stuff)

1. Does Paramiko 1.7.2 and 1.6.4 work with CentOS 4

2. If yes, what is the exact 'yum' command to install paramiko on CentOS 4?
I have tried all possible ones without success.

yum install paramiko
yum install python-paramiko(with and without version numbers)
python-paramiko.noarch

*[ru...@host]# yum search paramiko
Loading "fastestmirror" plugin
Loading "priorities" plugin
Searching Packages:
Setting up repositories
extras100% |=| 1.1 kB00:00
update100% |=|  951 B00:00
base  100% |=| 1.1 kB00:00
addons100% |=|  951 B00:00
Loading mirror speeds from cached hostfile
Reading repository metadata in from local files
0 packages excluded due to repository priority protections
No Matches found
*

Installing it without yum throws dependency problems which are never ending
: starting with python-crypto and python(abi) - which I am unable to find;
which will no doubt lead to other dependencies.

Is there any change that has to be made to the yum repository to point it to
look in a different place?

3. Alternatively, I also have apt-get on the CentOS box - can you tell me
some repos that I can add for apt-get as well?


Thanks,

Hi

Maybe you need to add the "rpmforge" repository.

Thanks Marcelo. That certainly helped.

Although, now I keep seeing this message:

*[r...@mpvmpc19 paramiko]# yum install Crypto.Util.randpool
Loading "fastestmirror" plugin
Loading "priorities" plugin
Setting up Install Process
Setting up repositories
not using ftp, http[s], or file for repos, skipping - ~
Loading mirror speeds from cached hostfile
Reading repository metadata in from local files
336 packages excluded due to repository priority protections

*

In the yum configuration file, there are may mirrors listed in a few files:
What should the priorities be? (I wnt to make sure no packages are excluded.
336 is a very large number)

Second: I was able to install python-paramiko. It seems to work with
Python2.3 (Python2.3 comes as default with CentOS). I have installed Python
2.4.6 and need the same to work with that. Any tips?

Hi

To be honest, I had never seen this messages before. I'm not familiar 
with CentOS 4, but seems that something is wrong.

About the python version. I would say that depends on how did you 
installed it. If you installed python from sources, then I think you 
have to build paramiko also. But I'm not sure.

M.

Re: [CentOS] package manager CentOS

[Raghu Narasimhan]

Thanks for your response.

I did install paramiko only after installing python2.4, so I am not sure why
it installed itself into the site-packages folder in
/usr/lib/python2.3/site-packages

(2) this is my /etc/yum.conf
*[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
installonlypkgs=kernel kernel-smp kernel-devel kernel-smp-devel
kernel-largesmp kernel-largesmp-devel kernel-hugemem kernel-hugemem-devel
distroverpkg=centos-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1
plugins=1

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
*
As you can see there are no exlcude parameters, so any idea where that 336
number is coming from?

This has nothing to do with mirrors. You definitely *want* priorities to keep 
your core CentOS files intact and not overwritten by rpmforge. Make sure that 
none of your repos has a lower priority number than centos-base and updates.

Super, thanks for the tip. Turned out the 'enabled' parameter was 1. Changed
it to 0 and all is well. Now 0 packages are excluded  due to priorities.

Can anyone share a default CentOS-Base.repo file here, please? Just for my
verification.

Happy to report resolution in the Paramiko problem too. The power of soft

Dare I venture another query:

I need to install python - matplotlib (pylab) on CentOS 4 with Python 2.4.6
(installed).

Yum (with romforge) and/or apt-get isn't able to get anything relevant. Has
anyone attempted this before? Even the offiical pages have no mention of
CentOS.

Do I need to add more to the repo file? I currently have base, update,

You choose to install different python version than the system one,

addons, extras, centosplus, contrib.

I'm not trying to hijack this thread but do you find any significant
overhead involved with using the ULOG target or packet loss in your
statistics?  Would you have a ULOG target very early on in your FORWARD
filter to log all packets?  Do those packets go to a ulogd instance and
then to disk (rrd to limit disk usage) for nfsen to use?

I'm concerned with losing packets in my current ntop configuration (not
using pf_ring) and am looking at less obtrusive alternatives like gulp
or ulog to first get ALL of the packets and with as little overhead as
possible move that data to a location where analysis can happen using
ntop or nfsen.  Thanks.

[CentOS] (off-topic)Update sii-3512A serial ata controller - which flash memory?

[Marcelo M. Garcia]

Hi.

I had to update the BIOS of a Silicon Image 3512A Serial ATA controller. 
I'm not using RAID.

When I run the updater program (updflash.exe), it asks me to choose 
flash memory from a list, something like: AMD Am29F010B (1 Megabit), AMD 
Am29LV01B (1 Megabit), etc.

How can I find out which is flash memory of the controller?

Thanks

You clearly did not understand what the priorities plug-in is and what
it is used for. By excluding a repository, 0 packages are excluded by
the priorities plug-in, but at the same time all the others that were
available in that repository will no longer be available anymore, so
in fact you have *less* packages than you did before.

Please read here:

If you're installing Python 2.4 on CentOS 4, it means you still did
not grasp the concepts of an Enterprise Linux distribution.

Please see:
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=17299&forum=38#forumpost62162
http://wiki.centos.org/FAQ/General#head-472ce8446ebcfc82ca1800f775ba0e629ac835c7
http://www.redhat.com/advice/speaks_backport.html

You will probably not get any support from this list for your Python
2.4 install on CentOS 4, since that is clearly not part of CentOS
itself.

Luckily for you, if you really need Python 2.4, you can move to CentOS
5, it will be present there.

If you want to stick to the bleeding edge, you'd better look into
distros such as Fedora and Ubuntu.

What you have done would be equivalent to buying a new automobile, and then
replacing the engine with one from another manufacturer. You are free to do
so, but you can't expect the dealership to be able to work on it anymore.

Did you read my reply? You *want* to have this enabled! It's fine that so many 
packages get excluded. Read what I wrote about priorities. There's also good 
tutorials on wiki.centos.org about this. So, no excuse to not know about it.

Re: [CentOS] Keepalive...

[John Doe]

I changed my apparently faulty nic, but it does not change anything...

I can reproduce this:

I bring down keepalived on lvs1.
Keepalived on lvs2 says it switched to MASTER but does nothing.
2 possibilities:
- If no VIP, as soon as I manualy add the VIP, everything is unlocked and he 
forward the requests...
- If there is a VIP, a ifdown+ifup of the interface linked to the web servers 
will unlock keepalived.
I bring up keepalived on lvs1, and it does not setup the VIP.
On lvs2, it says: "removing protocol VIPs", but the VIP is still there.
A ifdown+ifup on lvs2 of the interface linked to the web servers will unlock 
keepalived on lvs1...
And, from times to times, it will work as expected...

One thing I really do not understand is why restarting the nic linked to the 
webservers will unlock the vrrp on the other nic...

The only thing that almost never work is the service checks...
After one check, or a few at best, they just disapear...

On a slightly more helpful note, once you know the name of the rpm
which provided the package, you can use 'rpm -qd packagename' to see
the documentation included with that package. Not everything has a
manpage, but there might be a readme or other doc with info.

[CentOS] GNU Screen - emacs mode frustration

[Sean Carolan]

I like Gnu screen, but the choice of CTRL-A as the command sequence is
extremely unfortunate.  Like many other bash users, I use CTRL-A to
get back to the beginning of the line (emacs editing mode).

How do you all get around this problem?  Also, I'm wondering if there
is an easy way to get mouse scrolling to work when reviewing terminal
history in screen.  It's a pain in the arse to CTRL-A then ESC to be
able to scroll back.

If anyone else is looking for mouse wheel scrolling in GNU screen,
here's the solution I found.  I added this to my .screenrc and it
works quite well:

Hi

I tried. I think the chip is under the raiser for the second processor. 
Which I tried to remove but I couldn't. But it shouldn't ask this kind 
of stuff, which flash memory is in the chip. It seems very strange.

Thanks anyway.

Have you considered freenx and the NX client from 
http://www.nomachine.com instead?  It gives you the same 
disconnect/reconnect capability but with a full GUI desktop and fairly 
efficient cross-platform remote access.  I like it better than screen 
even when most of my windows are xterms.

Or, using the "f" option
  % rpm -qdf /usr/sbin/ss

Which could be combined with a simple grep:

  % grep -lw ss $(rpm -qdf /usr/sbin/ss)
  /usr/share/doc/iproute-2.6.18/RELNOTES
  /usr/share/doc/iproute-2.6.18/ss.ps

They're the 2 files I'd look at!

Jim Perrin tried to teach you to fish, but as you found out, there are a lot
of fish in lake Google!

OK.. Here is the fishing lesson.

"which ss" gives you a path

"yum provides /usr/sbin/ss" gives you a package name

"ls /usr/share/doc/$packagename" gives you some files to look at.

in that listing was ss.ps. Find a way to open or read ss.ps like gv or ggv and
you have some info.


CSI it ain't!

True. A better written flash program should be able to query the chip and ID
it. Silicon Image is a chip manufacturer, not a board designer. So the tools
are usually more generic.

Is it an add in card or is it built into the motherboard?

If it is built into the motherboard, the flash image is sometimes bound in
with the system bios, and is much harder to replace.

You can use the "Ctrl-A a" (minus a) keystroke, as described in the 
manual page:

DEFAULT KEY BINDINGS

   C-a a   (meta)Send the command character (C-a) to window. 
See escape command.

Re: [CentOS] GNU Screen - emacs mode frustration

[Brian Mathis]

To get a "Ctrl-A" to go to the bash shell to move to the beginning of
the line, use "Ctrl-A A", which sends the Ctrl-A through to the
program.

You can change the key to something else by adding the "escape"
command in your .screenrc.

bash in centos also usually understands the "Home" key on a regular PC
keyboard to move the cursor to the beginning of the line.

man screen; look for option '-e'. for the lazy : 'screen -e^Zz'; and ^z 
becomes the command char.

[CentOS] xen on CentOS 4.7

[Agile Aspect]

Hi - has anyone gotten Xen on CentOS 4.7 to run successfully
using Windows XP as  the guest OS?

I tried VirtualBox but it doesn't appear to work (at least for
Windows XP) for a CentOS 4.7 on a Dell Precision WorkStation
390 (quad.)

In fact, it pretty easy to crash the machine using the
command line interface.

There's blurb on the wiki

Move a native CentOS4 installation into a Xen DomU

but that appears to be Xen running on CentOS 5 install of
Xen.

I've installed the package kernel-xen.

I'm new to Xen and I'm not familiar with the jargon.

Any help would be greatly appreciated.

Xen is a full hypervisor that boots in FIRST, then loads a supervisory 
master OS into "dom0", typically this is CentOS5 (or another late model 
linux distribution) which Xen is bundled with Then you can load 
other guest OS's into dom1, dom2, etc which are collectively known as 
domU (eg, U = 1,2,3...).

VirtualBox is a guest hypervisor that runs under a parent OS.If you 
couldn't get Virtualbox working, you might try VMware Server, I've had 
very good luck running this on CentOS 4, and hosting both linux and 
windows domains under it.   


Note there are some constraints with all these virtualization systems... 
To run a 64 bit guest OS you need a processor that supports hardware 
virtualization assist, AMD-V or Intel VT.   Early Opteron and Xeon 64bit 
CPUs didn't support this, later ones do.

[CentOS] Firefox plugins gone (but only for one user)

[Rob Kampen]

Hi gurus
I have a CentOS 5.2 current x86_64 that has Thunderbird and Firefox 
working well for one user account (my wife) but will not play nice for 
my account.
I have uninstalled thunderbird and firefox (via yum) and re-installed - 
no change.
I have just wiped the .mozilla folder and started afresh, but it still 
shows no plugins, yet the /usr/lib/mozilla/plugins/ has the 
libflashplayer.so link etc.


How does all this stuff get hooked up.

I have previously installed firefox direct from their site and not used 
the CentOS supplied rpm, but now that RH say the light and provides a 
current version, I use the yum process to get my firefox installed.
Everything was working a week or so ago, but when I tried fixing things 
yesterday, all went rapidly pear shaped.
In firefox I pressed the Check Now button under Firefox > Preferences > 
Advanced > System Defaults and now its gone and lost all my plugins

Any idea how to get them back?

Looking on the support.mozilla.com/firefox site provides little linux 
help and seems oriented to windoze users.
Appreciate some insight from those who know how this distro hangs it all 
together.

I'll second John's suggestion to go with VMWare Server. Being also
pretty new and noob to all these, my first attempt at running WinXP
and Win2003 Server in VMWare server was almost plain sailing.

Xen on the other hand, well, let's just say I spent more time on it
and that machine was re-installed with a non-Xen kernel. And that was
on CentOS5 which supposedly works better with Xen. Maybe it's my
noobness, but the same noob skill applied to VMWare worked fine so...

Given VMWare's long history, I think Xen probably just needs more time
to all the details right.

Have you tried creating a new profile (not new Linux account) in
Firefox and see if the new profile will work with new installs of the
plugins? In Windows, profile manager starts by running firefox
-profilemanager, not sure exactly if the same works in Linux or you
gotta to a firefox --profilemanager.
