Reset adapter

sebastian — 2012-05-23T09:49:47

Hi,

one of our rented root-server has a problem with the network-adapter.The 
network is interrupted from time to time and i can not longer connect to 
our server. We can only reboote (remote) the server and restart the network.
I think it was an network-driver-problem from an "Intel Corporation 
82574L Gigabit Network" --- e1000e
But now i have install a new kernel-driver and i have the same problem 
again.

Here an extract of the logs:

Re: Centos 6 - vnc - authentication is required to set the network proxy used for downloading packages

John Stanley — 2012-05-23T08:25:50

Best way I found was to remove PackageKit and all its packages (Desktops
it causes a major user whine and loads of complaints).


That'll work also but for that one user account


Also yes packagekitd is a binary but controled by DBUS.  I think that is
just silly because it has no service command to stop it.  Stopping
'dbus' should take care of it but then you will prolly be stopping
really needed things.

Re: Repositories in CentOS 5.8

There are repositories that might not have such policies.
There are rpm downloads that are not yum-ified.

Re: Secure VNC access from iPad

Peter Brady — 2012-05-23T06:22:41

I use iTeleport.  The security settings inside it let me set up the ssh
tunnel and which port the VNC server is running.  iTeleport seems to
work with Linux, MacOSX and Windoze VNC servers no problem.  It even
lets me set up an ssh tunnel to a gateway machine and then port forward
to other machines behind the firewall.

The general procedure is:

1) create a new connection
2) set the name and port of the machine that is running VNC.  NOTE: this
does not have to be the same as the SSH gateway.
3) In security go to encryption and select SSH.  This is the machine
that is running SSH and as I said it can be a gateway machine or the VNC
itself.
4) Select the OS you are connecting to.  I suspect that iTeleport has
different click settings depending on what you are connecting to.

You are now done.

Good luck,
-pete

Hi,

How about using commercial vnc enterprise with aes encryption:

it requires vnc commercial, but it works ..

Secure VNC access from iPad

david — 2012-05-23T04:32:21

Dear Gurus

If any of you have been successful in using an iPad as a VNC client 
with SSH tunnelling, I'd love to know how it's done.  I have tried 
using the iSSH application, but without success.

I know that the server is accessible from a Windows client (using 
TigerVNC), via an SSH tunnel, so the server is properly configured.

If you have a working example, please let me know what magic sauce you used.

Thanks

David

Re: Centos 6 - vnc - authentication is required to set the network proxy used for downloading packages

John Stanley — 2012-05-23T04:12:45

Sounds like PackageKit to me. DBUS controls it.  I find it really
annoying....

/etc/yum/pluginconf.d/refresh-packagekit.conf
/usr/sbin/packagekitd

Alternatively you can set the yum proxy.

Centos 6 - vnc - authentication is required to set the network proxy used for downloading packages

Frank Cox — 2012-05-23T00:26:34

A window keeps popping up on my remote desktop stating "authentication is
required to set the network proxy used for downloading packages.  An
application is attempting to perform an action that requires privileges.
Authentication as the super user is required to perform this action" and asking
for the root password. If I hit cancel it comes back several minutes later.

I've found several references to this issue doing various google searches, but
nothing that clearly states a solution.

How can I get rid of this?

Centos 6 - tigervnc - numbers on keypad

Frank Cox — 2012-05-23T00:21:22

I have a ncurses-based program that runs on a vnc desktop on a remote
computer.  On Centos 5 you could enter numbers into the program using the
numeric keypad.  I just installed a new machine running Centos 6 to do this
same job and now numbers can only be entered using the numbers across the top
of the keyboard.  The program still recognizes the keys on the keypad when
numlock is not set (so you get home, pgup, left and right cursor, etc.) but I
get nothing when I set the numlock key.

Having said that, I do see activity when I set numlock and run the xev program,
so the keypresses are obviously getting through.

How can I make this thing accept numbers from the numeric keypad on Centos 6?
Do I have to re-write the ncurses program to recognize some different
keycodes?

This also does not count BGP routers, appliances, firewalls, many mail
servers, etc. It's a sample of web-facing web servers only.

I know in the shop I used to work at, only a fraction of our CentOS
servers were facing the web at all, and only a couple of those ran apache.

Re: CentOS in the world

Johnny Hughes — 2012-05-23T00:10:52

Well, these guys measure specifically webserver usage on the top websites:

http://w3techs.com/technologies/history_details/os-linux

We were #1, now we are #2 behind Debian.

BUT ... this does not show cpanel and plesk installs as they us custom
httpd that does not identify them as CentOS.

It is also web servers and does not include other things in the enterprise.

Re: Centos 6 - Networking: Some Queries

Somewhere on the net, undefined time ago (last 2-3 months?) I was asked 
same question and I investigated on my laptop that has NetworkManager 
service enabled. But I can not remember when/where I posted results. I 
think it was in "Linux" Facebook group but search gives nothing.

Do not take my word for it, create NM connection and observe what is 
happening. And I will run my laptop tomorrow and see if I wrote the 
search results somewhere.

Re: CentOS in the world

Digimer — 2012-05-22T23:57:13

There is no central recording of who uses what distributions. For this
reason, accurate numbers are impossible to get. Some projects try to
track by asking people to volunteer their usage info, but these are
hardly scientific and are likely highly inaccurate.

The best you can say is that CentOS is extremely popular and is one of
the most commonly used distribution in the server world. Whether it is
more or less popular than Debian, Ubuntu LTS, Red Hat Enterprise Linux
proper... No one can really say.

Any documents for python-kerberos package??

Gelen James — 2012-05-22T21:45:47


Hi all,

 I'm in a project to program Kerberos with Python. The headache encountered is, there is no documents on how to call the Kerberos module functions and results. 

when run 'help kerberos.checkPassword' in python, it just show things like:

Help on built-in function checkPassword in module kerberos:

checkPassword(...)
    Check the supplied user/password against Kerberos KDC.
(END) 
  
So the help doesn't give an idea on how to call the function, and what the the results and exceptions. 

Any one has successfully programmed python-kerberos, please shed a light on this. 

Thanks a lot.

Re: Repositories in CentOS 5.8

Les Mikesell — 2012-05-22T18:18:13

But with EPEL and others with policies to not overwrite base packages,
you won't get anything that you didn't explicitly install (assuming
you trust them to follow their policy...).    A possible exception is
that they consider RHEL as upstream so they might have a rare conflict
with something from centos extras or testing.

Also, you can make things a bit safer by setting 'enabled=0' in the
yum repo config file and then when you want to install or update a
package from there:
yum --enablerepo=repo_name install package_name

Re: Repositories in CentOS 5.8

2012-05-22T18:08:47

Following myself up, I just wanted to clarify that kmod-nvidia, and it's
required nvidia-x11-drv are the *only* things I pull from elrepo. Pulling
randomly would result in collisions, as one base or other repo package
would conflict on dependencies with an elrepo's dependencies.

Re: Apache error

John Stanley — 2012-05-22T18:07:55


It should just for a pointer...



Should also strace all subprocesses off the parent


You want to look for errors also.  You could post the entire thing to a
pastebin that bit is basically the start up.  If it is still doing it
the error should be in there and may be socket related also as your was.

But be aware that some Parent Processes are not aware of there Subprocs
and thus they can not be seen by the parent.  So that entails the error
will not be in the log!

Before you go any further:

httpd is running here
lsof |grep httpd
...
all process listed here

service httpd stop
lsof|grep httpd
...should show no processes listed
if you see any listed theres your problem maybe.

Your problem seems related to an older apache problem.
