Usul moves a notch up

Maxxed the RAM to 8 GB, just now.
Testing it right now while posting this.
Gnome 3 feels mighty snappy.

Usul's xorg.conf, another go...

What you know...
It's been a year or so, and the NVIDIA card (on the Thinkpad T410) has the same problem than while running Lucid Lynx.
The keyboard shortcut to lower or brighten the LCD doesn't work, it does launch the OSD icons for both up & down, but it doesn't actually do dink.
On the same laptop, with Lucid, it was necessary to do something similar.
Not a big deal.

We're a happy family

My current setup... Usul and Stilgar sharing the table.

And yet another one...

The third one (so far???) of those Fuzzy Panels on GNOME 3.
It seems like this has to be a software problem that goes beyond Unity; or maybe a hardware problem with the NVIDIA driver?

Falling down

Since last Friday, thankfully, temperature has been going down and down.
We had a brief, but really annoying, peak towards last Wednesday, with something close to 30 degrees.
May this winter never end.

From Precise to Gnome Remix

Last night did a wipe and clean install on Usul.
It had the Precise Pangolin, the first "production" install I did, back on May.

A plain vanilla 64 bits Precise, with a PPA added with an installation of GNOME 3, it performed A Ok, but I wanted a truly clean install, without all that Unity stuff that I'm positive I'll never ever going to use.

So, after an hour of base and updates installation, I've been restoring files all day long.

Tinker Taylor Thursday

Finally got to watch it last night.
Loved it, have to see it a couple of more times.
Got a bunch of new movies and series will be catching up a bit with some newer movies & classic TV series in the coming weeks.

The current Scientific Linux desktop

Green continues to be present...
Another one of those Mountain Lion wallpapers.

Chromium: reverse the controls

On Gnome 3, using Chromium with the option Hide system title bar and use compact borders and the option Use Classic Theme the window controls get reversed and set to the left of the window.

gconftool /apps/metacity/general/button_layout -t string -s "menu:minimize,maximize,close"

This puts things in order, and of course the change is instantaneous and doesn't need a logout or reboot.

Fuzzy Panel on GNOME 3 (2)

Another one of these...
This one after coming back from a Suspend, had to do a X Window re-init to get it back to normal.

CentOS 5: Install Rsnapshot via RPM

Another one, this time, Rsnapshot, my favorite backup utility...
Not as complex as the getting Nagios up & running on the CentOS box.

Get the RPM first:

wget http://pkgs.repoforge.org/rsnapshot/rsnapshot-1.3.1-1.el5.rf.noarch.rpm

And test how the thing would go...

# rpm --test -ivh rsnapshot-1.3.1-1.el5.rf.noarch.rpm 
warning: rsnapshot-1.3.1-1.el5.rf.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
       perl(XML::Simple) is needed by rsnapshot-1.3.1-1.el5.rf.noarch
       perl(XML::Validator::Schema) is needed by rsnapshot-1.3.1-1.el5.rf.noarch

First one its an easy one...

# yum install perl-XML-Simple

Installed:
  perl-XML-Simple.noarch 0:2.14-4.fc6                                                                                                                                                     

Dependency Installed:
  perl-XML-Parser.x86_64 0:2.34-6.1.2.2.1                                                                                                                                                 

Complete!

Another test...

# rpm --test -ivh rsnapshot-1.3.1-1.el5.rf.noarch.rpm

CentOS 5: Install Nagios via RPM

Last week took over an already running and in production box, with CentOS 5.8 (64 bits) installed and no extra repositories in use...
Since I don't want to add any extra repositorie to this production box, I've proceed to install the necessary packages by hand... First things first, so get it:

wget http://pkgs.repoforge.org/nagios/nagios-3.2.3-4.el5.test.x86_64.rpm

This one is a piece of cake:

# rpm --test -ivh nagios-3.2.3-4.el5.test.x86_64.rpm 
warning: nagios-3.2.3-4.el5.test.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
Preparing...                ########################################### [100%]

Lets see the how things go with the Nagios plugins:

wget http://pkgs.repoforge.org/nagios-plugins/nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm

And now the real fun begins:

# rpm --test -ivh nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm 
warning: nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
       perl(Net::SNMP) is needed by nagios-plugins-1.4.9-1.el5.rf.x86_64
       fping is needed by nagios-plugins-1.4.9-1.el5.rf.x86_64

Fping, no problems there:

wget http://pkgs.repoforge.org/fping/fping-3.1-1.el5.rf.x86_64.rpm
# rpm --test -ivh fping-3.1-1.el5.rf.x86_64.rpm

Full dressing test:

# ls -1

nagios-3.2.3-4.el5.test.x86_64.rpm
nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm

error: Failed dependencies:
       perl(Net::SNMP) is needed by nagios-plugins-1.4.9-1.el5.rf.x86_64

So get it, and run another test:

wget http://pkgs.repoforge.org/perl-Crypt-DES/perl-Crypt-DES-2.05-3.2.el5.rf.x86_64.rpm
rpm --test -ivh nagios-3.2.3-4.el5.test.x86_64.rpm nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm \
fping-3.1-1.el5.rf.x86_64.rpm perl-Net-SNMP-5.2.0-1.2.el5.rf.noarch.rpm perl-Crypt-DES-2.05-3.2.el5.rf.x86_64.rpm

Preparing...                ########################################### [100%]

Bingo! So, just do the install and that's it:

# rpm -ivh nagios-3.2.3-4.el5.test.x86_64.rpm nagios-plugins-1.4.9-1.el5.rf.x86_64.rpm \

Another one of these... Installation without repository declaration, except for the VirtualBox repo... Compared to the ones I did lately -specially VLC- this one is a real piece of cake...

First things first... So, install dkms...

Scientific Linux: Installing WINE via RPM

And here is another one... Installing WINE without using a third party repository, just like I did with VLC, mostly to -hopefully- avoid conflicts with dependencies on the long run...
This is on a Scientific Linux 32 bits with all the updates installed as of today.

First get the RPM package:

wget http://pkgs.repoforge.org/wine/wine-1.2.3-1.el6.rf.i686.rpm

And then test the RPM install to see how the thing goes:

> sudo rpm --test -ivh wine-1.2.3-1.el6.rf.i686.rpm 
[sudo] password for XXXXXXX: 
warning: wine-1.2.3-1.el6.rf.i686.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

 wine-esd = 1.2.3-1.el6.rf is needed by wine-1.2.3-1.el6.rf.i686
 wine-gecko = 1.0.0 is needed by wine-1.2.3-1.el6.rf.i686
 wine-jack = 1.2.3-1.el6.rf is needed by wine-1.2.3-1.el6.rf.i686
 wine-ldap = 1.2.3-1.el6.rf is needed by wine-1.2.3-1.el6.rf.i686
 wine-nas = 1.2.3-1.el6.rf is needed by wine-1.2.3-1.el6.rf.i686
 wine-twain = 1.2.3-1.el6.rf is needed by wine-1.2.3-1.el6.rf.i686

Things don't look so bleak as they did on the VLC install... So let's just start downloading some stuff... Get all of the packages onto the same directory on your box.

wget http://pkgs.repoforge.org/wine/wine-capi-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-cms-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-core-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-esd-1.2.3-1.el6.rf.i686.rpm
wget ftp://rpmfind.net/linux/dag/redhat/el6/en/i386/dag/RPMS/wine-gecko-1.0.0-1.nodist.rf.i386.rpm
wget http://pkgs.repoforge.org/wine/wine-ldap-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-jack-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-nas-1.2.3-1.el6.rf.i686.rpm
wget http://pkgs.repoforge.org/wine/wine-twain-1.2.3-1.el6.rf.i686.rpm

And then, once you are on the directory, give it another go...

> sudo rpm --test -ivh *rpm
[sudo] password for XXXXXXX: 
warning: wine-1.2.3-1.el6.rf.i686.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

 libesd.so.0 is needed by wine-esd-1.2.3-1.el6.rf.i686

This time, some of the packages are available on the repositories, pretty easy to install:

> sudo yum install xmessage
> sudo yum install esound-libs

You know how it goes... Another test:

> sudo rpm --test -ivh *.rpm
warning: wine-1.2.3-1.el6.rf.i686.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY
error: Failed dependencies:
 libmpg123.so.0 is needed by wine-core-1.2.3-1.el6.rf.i686

Get the last package using the hard wget way:

wget http://pkgs.repoforge.org/mpg123/mpg123-1.14.2-1.el6.rf.i686.rpm

Install it, and then, finally, test the WINE install:

> sudo rpm -ivh mpg123-1.14.2-1.el6.rf.i686.rpm
> sudo rpm --test -ivh wine-*.rpm
warning: wine-1.2.3-1.el6.rf.i686.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

Goes Ok, so here it goes the final bit:

Ciso: IP Phone Home

Yesterday got me a "new" Cisco phone from work.
The old and pretty crappy Budge Tone 201 that I have at home was nearly completely broken and totally beat up.

So the powers that be gave me a Cisco IP Phone 7940.

Setting it up on my LAN was pretty much a piece of cake, had to disable DHCP, gave it the IP address that the Budge Tone was using, etc... Only thing I had to do was to add a TFPT server IP address pointing to nowhere inside my LAN in order to accept the fixed IP address & settings.

It works perfectly well behind the D-Link DIR-601 router, no need to set anything special in terms of port forwarding or stuff like that.
The difference in craftsmanship between the two phones is amazing.
