Apache WebDav no Ubuntu

Link: http://www.digital-arcanist.com/sanctum/article.php?story=20070427101250622

This HOWTO will show you how to create WebDAV enabled directories hosted on your Apache webserver. I wrote this using Ubuntu Server 7.04, but it should work on previous Ubuntu releases and (with only minor modifications) any other Linux distro.

  1. What is WebDAV?
  2. WebDAV stands for Web-based Distributed Authoring and Versioning. It was designed to allow groups of individuals to edit and manage files stored on a web-server. The protocol allows the creation of "web-shares" which can be used for file storage, collaborative projects, editing websites themselves, and any number of other things. WebDAV supports features like editing, copying, and moving of files, file locks, resource lists, and file property modification. Most operating systems, including MS Windows, support WebDAV directories.
  3. Install the Proper Software
  4. The first thing you will need (obviously) is a functioning apache2 webserver. If you happened to have install Ubuntu Server Edition with the LAMP option, then you're set. Otherwise, you'll need to get a few things with apt. Do this however you want; I will use the command line. While you're at it, you might as well get PHP to go with it.
    
    apt-get install apache2 php5 libapache2-mod-php5
    
  5. Add Modules
  6. Fortunately, Apache 2.x comes with mod_dav already installed, we just have to activate it. We can do this by making some symlinks.
    
    cd /etc/apache2/mods-enabled
    ln -s ../mods-available/dav* .
    
  7. Create LockDB file for WebDAV
  8. Next we need to set up a DAVLockDB file for WebDAV to use. This is a very important step, as you'll wind up with Internal Server Errors if you try to use WebDAV without it.
    
    mkdir /usr/share/apache2/var
    touch /usr/share/apache2/var/DAVLock
    chown -R www-data:www-data /usr/share/apache2/var
    
  9. Setup Authentication and Add Users
  10. WebDAV can open your web server up to security risks. You don't want just anyone to wander in and change your files! There are several ways you can do authentication for your WebDAV directory, but htpasswd is the easiest and probably best for most cases. We'll make the passwords using MD5 and store them where we store the apache configurations and add an initial user while we're at it.
    
    htpasswd -m -c /etc/apache2/.htpasswd
    
    You can use this command to add more users later or change their passwords. Just remember to remove the -c option or you'll truncate your password db every time!
  11. Create the WebDAV Directory
  12. Okay, almost done. Let's make a directory in our web document root where we will run our WebDAV. I'm calling it myWebDAV. This is the folder in which your authorized users will be able to add, delete, and modify files. The directory will need to be writable by the web server.
    
    mkdir /var/www/myWebDAV
    chown www-data:www-data /var/www/myWebDAV
    
  13. Configure Apache
  14. Now all we need to tell Apache how to use WebDAV and where to enable it. This consists of adding a few definitions to the user-defined config file at /etc/apache2/httpd.conf. Open that file with an editor and add lines similar to those below.
    
    ## Location of the DavLock file
    DavLockDB /usr/share/apache2/var/DavLock
    
    ## Set up the myWebDAV directory to use WebDAV and authentication
    
    Dav On
    AuthName "WebDAV Login"
    AuthType Basic
    AuthUserFile /etc/apache2/.htpasswd
    ## Limit access for enhanced security
    
    require valid-user
    
    Order allow,deny
    Allow from all
    
    
  15. Restart Apache and Test
  16. That's it! Restart your web server and you're good to go. You and your friends/coworkers/etc can now login and modify the files at http://your.domain.com/myWebDAV.
    
    /etc/init.d/apache2 restart

Private IP Subnets

link: http://networking.ringofsaturn.com/IP/subnets.php

Private IP Addresses
RFC 1918 requests that organizations make use of the private Internet address space for hosts that require IP connectivity within their enterprise network, but do not require external connections to the global Internet. For this purpose, the IANA has reserved the following three address blocks for private internets:
10.0.0.0/8
127.0.0.0/8
172.16.0.0/12
192.168.0.0/16
IP's above 224.0.0.0 are used for both multicast and experimental purposes.

Instalação VMWARE Server 2 no UBUNTU 8.04


Instale alguns pré-requisitos:
sudo apt-get install build-essential

Crie um diretório para salvar os arquivos de download do site da VMWare.
sudo mkdir -p /usr/src/VMWare

Faça o download dos arquivos navegando pelo site: http://www.vmware.com/download/server
Assim você terá o free serial numbers fornecidos durante o processo de download oficial.

Execute os comandos de instalação:
sudo bash
cd /usr/src/VMWare
tar xzf VMware-server-2.0.0-122956.i386.tar.gz

cd /usr/src/VMWare/vmware-server-distrib
sudo ./vmware-install.pl

Select defaults.
Enter your serial # during the installation.

Start vmware (as a user, not root)

Entre com o comando abaixo para iniciar o vmware
vmware

Depois pelo Firefox:
https://localhost/ui

Siga estas instruções:
The first time you load the page, firefox will give you a warning. Go ahead and add an exception.
You will get a log in screen, log in as root.
Go to the "Permissions tab" -> click "New Permission"
From the pull down menus, add your user as an "Administrator"
Log out and back in as your user (rather then root).
To get the web interface working (console tab), first create a Virtual machine. Once you start your first VM you need to allow firefox to install an addon. To do this, start your new VM, then click on the "Console" tab. You will see a black window with a text message "The VMWare Remote Console Plug-in is not installed ..."
Click on the yellow "Install plugin". You will get a "warning" from firefox "Firefox prevented this site (127.0.0.1) from asking you to install software on your computer". Click the "Allow" button on the upper Left and install the plugin.
You will the need to re-start firefox, again log in and start your virtual machine. This time you will get notice that the VMWare Remote Console Plug-in has been installed. Again click the Console tab. You will now see a black screen with the VMWare logo. Click anywhere in this screen to start the VMWare graphical screen (in a separate window).
From the VMWare console you have some limited options for admin of the VM (stop / reboot and access to removable devices).
You can close Firefox and your Virtual Machine will continue to run. You can close the VMWare window or even log off and the virtual machine will continue to run

Unfortunately, there is not a menu option to re-start the console, you have to re-start firefox, log in, and again start the console.

Troca de acesso da pasta

Um comando que sempre preciso lembrar como é: alterar o proprietário e o acesso de pastas recursivamente.

Para alterar o proprietário e grupo de uma pasta recursivamente:
sudo bash
chown -vhR root:users /home/Data
chown -vhR root:users /home/Lixeira
chown -vhR root:users /home/Public

Um conteúdo adulto pode ser restrito para um usuário apenas, por exemplo:
sudo bash
chown -vhR root:aarvati /home/Data/Pictures/Sexo
chown -vhR root:aarvati /home/Data/Video/Sexo

Alterar a permissão de acesso de uma pasta recursivamente, por exemplo a estrutura de pastas abaixo terá suas configurações alteradas:
sudo bash
chmod -cR 770 /home/Data/Backup
chmod -cR 770 /home/Data/Example
chmod -cR 770 /home/Data/Fax
chmod -cR 770 /home/Data/Machines
chmod -cR 770 /home/Data/Music
chmod -cR 770 /home/Data/Pictures
chmod -cR 770 /home/Data/Softs
chmod -cR 770 /home/Data/Video
chmod -cR 770 /home/Data/WebSites
chmod -cR 777 /home/Public
chmod -cR 770 /home/Lixeira

Os números representam a permissão do proprietério, do grupo e de outros respectivamente.
A permissão de acesso é feita somando-se os números 4 para leitura, 2 para escrita e 1 para execução. Assim o número 7 = (4+2+1), significa acesso total de leitura, gravação e execução.
 

Como fazer backup do Evolution

LINK: http://www.avila.eti.br/2007/06/21/1182453660000.html


Saiba quais as pastas e arquivos necessários para o backup.

Se você, assim como eu, utiliza o Evolution no Ubuntu como cliente de e-mail, já precisou fazer backup de suas mensagens para passar para outro computador. Sinceramente, achei este esquema mais fácil do que os backups do Thunderbird.

Siga os seguintes passos para criar um backup dos e-mails/configurações do Evolution:

Passo 1: Encerre os serviços evolution e gconftool-2:

gconftool-2 --shutdown
evolution --force-shutdown


Passo 2: Crie um arquivo com os dados e os arquivos de configuração.

Nota: para salvar os dados e configurações completas do Evolution, você precisa salvar os seguintes arquivos/diretórios:
1. ~/.evolution/
2. ~/.gconf/apps/evolution/
3. ~/.gnome2_private/Evolution


O seguinte comando pode cuidar de fazer isto:
cd
tar -cvzf evolution-backup.tar.gz .evolution .gconf/apps/evolution .gnome2_private/Evolution


Passo 3: restaurar o backup

Agora o arquivo evolution-backup.tar.gz é o backup que você tanto queria. Você pode movê-lo para um outro computador com Ubuntu, e simplesmente descompactar o arquivo dentro do diretório /home/nomedousuario para restaurar o backup.

Para fazer isto:

gconftool-2 --shutdown
evolution --force-shutdown
cd
tar xzf evolution-backup.tar.gz
gconftool-2 --unload evolution_setting.xml
gconftool-2 --load evolution_setting.xml

Instalando uShare

Link sobre uPNP: https://coherence.beebits.net/wiki/Resources

link: http://ushare.geexbox.org/
At first you need to be sure that you have setup a multicast route for UPnP messages. If you don't but have a default route attributed, then this later will be used. Otherwise, simply declare a new route for UPnP multicasts (for example using eth0 interface) :
route add -net 239.0.0.0 netmask 255.0.0.0 eth0
uShare runs from the console only. It supports the usual --help option which displays usage and option information.
Options:
-n, --name=NAME              Set UPnP Friendly Name (default is 'uShare')
-i, --interface=IFACE        Use IFACE Network Interface (default is 'eth0')
-f, --cfg=FILE               Config file to be used
-p, --port=PORT              Forces the HTTP server to run on PORT
-q, --telnet-port=PORT       Forces the TELNET server to run on PORT
-c, --content=DIR            Share the content of DIR directory (default is './')
-w, --no-web                 Disable the control web page (enabled
by default)
-t, --no-telnet              Disable the TELNET control (enabled by default)
-o, --override-iconv-err     If iconv fails parsing name, still add to media contents (hoping the renderer can handle it)
-v, --verbose                Set verbose display.
-x, --xbox                   Use XboX 360 compliant profile
-d, --dlna                   Use DLNA compliant profile (PlayStation3 needs this)
-D, --daemon                 Run as a daemon.
-V, --version                Display the version of uShare and exit
-h, --help                   Display this help
uShare expects at least one directory argument (-c argument), specifying where multimedia files are stored. You should probably also use the -i option to specify which interface uShare should listen on.
ushare -c /shares
ushare -c /shares1 --content=/shares2
You can also perform remote control of uShare UPnP Media Server through its web interface. This let you define new content locations at runtime or update the currently shared one in case the filesystem has changed.

Just go to :
http://ip_address:port/web/ushare.html
See the manual page for more details :
man ushare
Instalando uShare
sudo apt-get install ushare

sudo dpkg-reconfigure ushare

sudo gedit /etc/ushare.conf

# /etc/ushare.conf
# Edit this file with 'dpkg-reconfigure ushare'
# Configuration file for uShare

# uShare UPnP Friendly Name (default is 'uShare').
USHARE_NAME=server_uShare

# Interface to listen to (default is eth0).
# Ex : USHARE_IFACE=eth1
USHARE_IFACE=eth0

# Port to listen to (default is random from IANA Dynamic Ports range)
# Ex : USHARE_PORT=49200
USHARE_PORT=49200

# Port to listen for Telnet connections
# Ex : USHARE_TELNET_PORT=1337
USHARE_TELNET_PORT=1337

# Directories to be shared (space or CSV list).
# Ex: USHARE_DIR=/dir1,/dir2
USHARE_DIR=/home/Data/Music,/home/Data/Pictures,/home/Data/Video

# Use to override what happens when iconv fails to parse a file name.
# The default uShare behaviour is to not add the entry in the media list
# This option overrides that behaviour and adds the non-iconv'ed string into
# the media list, with the assumption that the renderer will be able to
# handle it. Devices like Noxon 2 have no problem with strings being passed
# as is. (Umlauts for all!)
#
# Options are TRUE/YES/1 for override and anything else for default behaviour
USHARE_OVERRIDE_ICONV_ERR=

# Enable Web interface (yes/no)
ENABLE_WEB=yes

# Enable Telnet control interface (yes/no)
ENABLE_TELNET=no

# Use XboX 360 compatibility mode (yes/no)
ENABLE_XBOX=yes

# Use DLNA profile (yes/no)
# This is needed for PlayStation3 to work (among other devices)
ENABLE_DLNA=yes


E por fim:
sudo route add -net 239.0.0.0 netmask 255.0.0.0 eth0

sudo /etc/init.d/ushare restart

Instalando Pidgin com Skype

Link: http://eion.robbmob.com/
Alternativa: http://www.stumblerz.de/?p=122

Instale os programas com: sudo apt-get install skype pidgin

Os repositórios medibuntu serão acionados. Ver post específico.

Depois instale o pacote que permite acessar o skype pelo pidgin:
wget http://eion.robbmob.com/skype4pidgin.deb
sudo dpkg -i skype4pidgin.deb

Instruções detalhadas do site: http://eion.robbmob.com/README.txt


Skype plugin for Pidgin/Adium/libpurple
=======================================

If you've found this file then you'll probably realise that this is the Skype plugin for libpurple.  Yes, it does require Skype to be running as it uses the Skype API to communicate with a running copy of Skype.  The Windows and Linux versions were made by me in a week.  The OS X version has taken lots longer, but it needed reverse engineering of the Skype.framework before it was GPL compatable.


History/Ramble
==============

It seems people have wanted a Skype plugin for Gaim/Pidgin/Adium for a long time, however it seems to be rare to find a glib coder who uses Pidgin who also uses Skype.  There seems to have been a lot of stigma over Skype being closed-source and evil, however there has still been a demand for this plugin and the end-user has suffered for long enough.  That was kind of my motivation.  Plus I enjoy both Pidgin and Skype and it made sense to me to combine the two.  I know it's not the ideal solution (to still have Skype running), but if you're going to have it running, you might as well have your buddies in one place, right?


Installation
============

For the binary version of the plugin, either install the appropriate package or .exe for your distro or copy libskype to the appropriate plugins directory.  On Windows its normally C:\Program Files\Pidgin\plugins, on Linux it's normally /usr/lib/purple-2/ or ~/.purple/plugins
On OSX, double click on SkypePlugin.AdiumPlugin to install (may need a restart of Adium).  You may need to delete the old version which is at ~/Library/Application Support/Adium 2.0/Plugins.  If upgrading to Adium 1.2, you will need to delete the account and re-add it.

To install swanky looking icons, extract skype_icons.zip to the pixmaps/pidgin/protocols directory (on Windows, C:\Program Files\Pidgin\pixmaps\pidgin\protocols).
To have the right smilies/emotes in your Skype chat messages, copy themes into the pixmaps/pidgin/emotes/default folder.

To compile from source, the easiest way is extract libskype.zip into the ${PIDGIN_SOURCE}/libpurple/plugins/ directory and compile using "make libpurple.so" or "make -f Makefile.mingw libpurple.dll"


Known Issues
============

* Pidgin crashes at startup if Skype not running (Linux)
* No notification popup on file being received/notificaitons (Windows)

* Skype sounds still play even when it's hidden

* Adium doesn't show file transfer progress (OS X)
* Unable to send file from within Adium (API Limitation)
* Send file doesn't use the built in libpurple methods. (API Limitation)
* Linux version still opens up Skype message windows. (API Limitation)
* Linux/OSX version doesn't show buddy icons. (API Limitation)
* No typing notifications with official Skype clients. (API Limitation)


FAQ
===

Q: Does this plugin require Skype to be running?
A: Yes.

Q: Can you make a version that doesn't need Skype?
A: Not possible right now.

Q: What version of Pidgin do I need to be able to run this plugin?
A: You need at least version 2.1.1 of Pidgin.  You can download updates to Pidgin from www.pidgin.im

Q: What version of Adium do I need to be able to run this plugin?
A: You need version 1.2 to run the latest version of the plugin or 1.1 to run the older version of the plugin.  You can download updates to Adium from www.adiumx.com

Q: Where can I get the protocol icons?
A: Download skype_icons.zip from this website and install the icons into the appropriate pixmaps/pidgin/protocols directory.

Q: How can I hide the Skype icon from the tray?
A: I'm planning to automate and make this cross-platform.

Q: How can I hide the Skype icon from the tray on Windows?
A: Right click on the taskbar, click Properties, click the Customize... button, find Skype in the list, click on it, choose 'Always Hide' from the drop-down box.

Q: How can I hide Skype in OSX?
A: Focus (click on) the Skype window, press ⌘+H to hide the application.  Alternativly, focus the Skype window and choose 'Hide Skype' from the 'Skype' menu.

Q: How can I hide Skype in Linux?
A: A bit more tricky.  What works well for me, is turning off message windows in the Notifications settings in Skype (Options->Chat->Display an event notification).  Otherwise, you can leave the message window open, but move it to another workspace so that it doesn't bother you any more.

Q: The Windows version has feature "X", but the Linux/OSX version doesn't
A: The API on Linux/OSX is more restrictive than the Windows API.  Try keeping up to date with the latest versions of Skype to take advantage of these features as they are implemented by the Skype developers.

Q: Why is "Send file..." not in the conversation menu, but in the "More..." menu instead?
A: The short answer is that Skype doesn't allow file sending in the way that libpurple wants, so it has to do it through a Skype popup instead of a Pidgin popup

Q: I set my status to "Away" but Skype still shows me as "Online"?
A: For some reason the Skype tray icon isn't always what is being seen at the other end.  Just ignore it :)

Q: On OSX, I get bugged with the "Allow API Access" window from Skype every time Adium starts?
A: Turn on "access for assistive devices" See: http://images.apple.com/applescript/uiscripting/gfx/gui.03.jpg

Instalando eeepc-ubuntu on 1000H

Link: http://www.array.org/ubuntu/
Link: http://forum.eeeuser.com/viewtopic.php?id=38030

Primeiro instale o ubuntu através de um cartão de memória ou pendrive com o utilitário UNetbootin. É preciso que o cartão esteja formatado com FAT32 e tenha 1Gb.
Utilize a distro :
http://sourceforge.net/project/downloading.php?group_id=213463&filename=ubuntu-eee-8.04.1.iso&99571803
http://www.mininova.org/tor/1790364


Pode criar um USB distro com o software abaixo:
http://downloads.sourceforge.net/unetbootin/unetbootin-eeeubuntu-windows-238.exe?modtime=1214975248&big_mirror=0

Instruções em inglês no site:
http://www.ubuntu-eee.com/index.php5?title=Main_Page


sources.list
adicionar a linha: deb http://www.array.org/ubuntu hardy eeepc
com os comandos:
wget http://www.array.org/ubuntu/array.list
sudo mv -v array.list /etc/apt/sources.list.d/

chave pública:
wget http://www.array.org/ubuntu/array-apt-key.asc
sudo apt-key add array-apt-key.asc

Atualize o cache do apt: sudo apt-get update

Instalação do kernel personalizado para o eeepc:
sudo apt-get install linux-eeepc linux-headers-eeepc

Reinicie pelo novo kernel, se der tudo certo retire as referências ao kernel genérico:
sudo apt-get remove linux-generic linux-image-generic linux-headers-generic linux-restricted-modules-generic

opcionalmente instaale também:
sudo apt-get install linux-image-eeepc

Altere o /etc/fstab retirando a linha do cdrom para não ter conflitos no futuru:
/dev/sdc1       /media/cdrom0   udf,iso9660 user,noauto,exec 0       0

Depois crie o diretório: sudo mkdir /media/MMCSD
e acrescente no sudo gedit /etc/fstab :
/dev/sdb1 /media/MMCSD auto user,auto,exec,rw 0 0

Para trabalhar com telas pequenas faça:
gconftool-2 --set /apps/nautilus/preferences/desktop_font --type string "Sans 8"
gconftool-2 --set /desktop/gnome/interface/document_font_name --type string "Sans 8"
gconftool-2 --set /desktop/gnome/interface/font_name --type string "Sans 8"
gconftool-2 --set /apps/metacity/general/titlebar_font --type string "Sans Bold 8"
gconftool-2 --set /desktop/gnome/interface/monospace_font_name --type string "Monospace 8"

;;
# Fn+F9 -- increase volume
00000015)
acpi_fakekey 115
;;
esac

E depois:

sudo chmod +x /etc/acpi/eeepc-hotkeys.sh

sudo /etc/init.d/acpid restart

gconftool-2 --set /desktop/gnome/sound/default_mixer_tracks --type list --list-type string "[PCM]"

Executar módulos ao iniciar o eeepc:
sudo gedit /etc/modules

pciehp pciehp_debug=1 pciehp_force=1
acpi-cpufreq

Tem post que aconselha estes módulos:
fuse
lp
i2c-i801
eee
eeepc-acpi
p4_clockmod
cpufreq_ondemand
ath_pci
pciehp pciehp_debug=1 pciehp_force=1
snd_hda_intel model=auto

Mas este comentário é interessante:

NOTE: The EeePC does require extra modules not included in this list (like rt2860sta, atl1e, eeepc_acpi,
snd_hda_intel), but Ubuntu should automatically load them on startup. There is no need to explicitly specify these modules within this
file.

Fetchmail

Link: http://linuxpoison.blogspot.com/2008/07/fetchmail-configuration.html

First make an empty file named “.fetchmailrc” in your home directory. The easiest way for it is to use the command “touch”.
$ cd ~/
$ touch .fetchmailrc

Then change the permission of that file to 600 (that is, readable and writable only by the owner of the file).
$ chmod 600 .fetchmailrc

Now add these lines to .fetchmailrc file

poll SERVER with proto PROTOCOL
user REMOTE_USER there with password REMOTE_PASSWORD is LOCAL_USER here

You must replace all the capital-letter words with the real values.

SERVER is the name of server you use to receive e-mails.
PROTOCOL is the type of SERVER (for example, IMAP or POP3). If you don’t know, use AUTO.
REMOTE_USER is the user name of the account you have on the SERVER.
REMOTE_PASSWORD is the password for REMOTE_USER.
LOCAL_USER is the user name of the account you have on your machine. Don’t use “root”.

Example: You can have multiple account configuration

poll pop.anydomain.com with proto POP3
user nikesh there with password password is otheruser here

poll pop.otherdomain with proto POP3
user user1 there with password pass is user2 here

It’s the time to run fetchmail.
$ fetchmail

You can use “-v” option to see what is going on.
$ fetchmail -v

For an automatic pick-up of your mail, you could write your own script that calls fetchmail every hour and delivers the mail. But in stead of using the cron-daemon you can start fetchmail also in daemon mode. This is very easily done by this command : fetchmail –daemon 3600

Interval (3600) is a numeric argument that specifies the polling interval in seconds.

Link : http://www.howtoforge.com/debian_etch_fetchmail

Fetchmail is a program for retrieving emails from remote servers. Imagine you have five email accounts on five different servers. Of course, you don't want to connect to each of them to get your emails. This is where fetchmail comes into play. If you have a user account on a Linux server, you can make fetchmail download emails from remote servers and put them into just one mailbox (the one of your Linux user), from where you can retrieve them with your email client (e.g. Thunderbird or Outlook).
Or imagine you have an email account at a provider that doesn't do spam- and virus filtering. In that case you could use fetchmail to download the mails to your own server and pipe them through spam- and virus filters (e.g. SpamAssassin and ClamAV) before you download the mails with your email client.
I do not issue any guarantee that this will work for you!
apt-get install fetchmail
gedit /etc/default/fetchmail
# This file will be used to declare some vars for fetchmail
START_DAEMON=yes
gedit /etc/fetchmailrc

# /etc/fetchmailrc for system-wide daemon mode
# This file must be chmod 0600, owner fetchmail

set daemon        300                # Pool every 5 minutes
set syslog                        # log through syslog facility
set postmaster  root
set no bouncemail                # avoid loss on 4xx errors
# on the other hand, 5xx errors get
# more dangerous...

##########################################################################
# Hosts to pool
##########################################################################

# Defaults ===============================================================
# Set antispam to -1, since it is far safer to use that together with
# no bouncemail
defaults:
timeout 300
antispam -1
batchlimit 100

poll pop.someprovider.tld protocol POP3 user "falko@someprovider.tld" there with password "secret" is falko here
poll mail.otherprovider.tld protocol POP3 user "ftimme" there with password "verysecurepassword" is falko here fetchall
poll mailin.tillsprovider.tld protocol POP3 user "tbrehm" there with password "iwonttellyou" is till here keep

At the beginning of the file we have some global options such as set daemon 300 (which means fetchmail should retrieve emails every 300 seconds) that control the operation of the program. The meanings of the above options are as follows:
  • set daemon: Set a background poll interval in seconds.
  • set syslog: Do error logging through syslog.
  • set postmaster: Give the name of the last-resort mail recipient (default: user running fetchmail, "postmaster" if run by the root user).
  • set no bouncemail: Direct error mail to the local postmaster (as per the "postmaster" global option above).
Then we have the server and the user options options. These go together into the lines beginning with poll; if there are options that are the same for each poll line, we can as well specify them before the poll lines in a section that begins with defaults: (such as timeout, antispam, and batchlimit in our example).
  • timeout: Server inactivity timeout in seconds (default 300).
  • antispam: Specify what SMTP returns are interpreted as spam-policy blocks.
  • batchlimit: Specify the maximum number of messages that will be shipped to an SMTP listener before the connection is deliberately torn down and rebuilt (defaults to 0, meaning no limit).
The poll lines are self-explanatory; as you see fetchmail retrieves emails from both of falko's external email accounts and puts them into one account.
You will notice that the poll lines have different endings (e.g. nofetchall (default), fetchall, keep, nokeep). The meanings are as follows:
  • nofetchall: Retrieve only new messages (default). If nothing else is specified (e.g. fetchall, keep), this means nofetchall.
  • fetchall: Fetch all messages whether seen or not.
  • keep: Don't delete seen messages from server.
  • nokeep: Delete seen messages from server.
To learn more about all available configuration settings, take a look at man fetchmail
chmod 600 /etc/fetchmailrc
chown fetchmail /etc/fetchmailrc
/etc/init.d/fetchmail start

sudo apt-get install dhcp3-server
Note: Don’t be alarmed if the startup fails; that’s because you haven’t configured it yet.

First, we need to tell the DHCP server to only run on eth1:
sudo gedit /etc/default/dhcp3-server

enter the following line save and exit file.
INTERFACES="eth1"

sudo gedit /etc/dhcp3/dhcpd.conf
ddns-update-style none;
default-lease-time 600;
max-lease-time 7200;

#Broadcast que será utilizado na rede
option broadcast-address 192.168.2.255;
#Roteador da rede que neste caso será o próprio servidor DHCP
option routers 192.168.2.1;
#Servidor de domínio da rede (DNS) que também é o próprio servidor
option domain-name-servers 192.168.2.1;
#Nome do domínio da rede

option routers router.casa.lan;
}

Configurar interface ETH1
cp /etc/network/interfaces /etc/network/interfaces.old
gedit /etc/network/interfaces

auto eth1
iface eth1 inet static

http://www.ldap.org.br/modules/ldap/files/files///samba+openLDAP+qmail.pdf

Como fazer a instalação:

apt-get install slapd ldap-utils

Edite o arquivo /etc/ldap/slapd.conf e troque todos os dc para o dc que você quiser.
Por exemplo: dc=casa,dc=lan

Descomente a instrução:
rootdn "cn=admin,dc=casa,dc=lan"

E acrescente uma linha de senha que é gerada pelo comando:
slappasswd


Por ex:
rootpw {SSHA}vv2y+i6V6esazrIv70xSSnNAJE18bb2u


Reinicie o ldap server:
invoke-rc.d slapd restart

Ferramentas GUI:
apt-get install apache2 libapache2-mod-php5 php5 php5-cgi php5-ldap
apt-get install phpldapadmin

Talvez seja necessário aumentar a meméria disponível para o php5 no arquivo:
/etc/php5/apache2/php.ini
e reiniciar o apache com:
/etc/init.d/apache2 restart

Edit o arquivo /etc/ldap/ldap.conf

Ports for the Firewall
LDAP runs on port 389/tcp by default and LDAP over SSL is 636/tcp.

Para reindexar utilize os comandos:
invoke-rc.d slapd stop
slapindex -v
chown openldap /etc/ldap/*.conf
invoke-rc.d slapd start

Para acertar o log edite o arquivo /etc/syslog.conf e coloque no final:
local4.* /var/log/ldap.log

Reinicie o log:
invoke-rc.d sysklogd restart

Instale agora a ferramenta de gerenciamento da base via shell:
apt-get install ldapscripts
Se dermos um "ldapsearch -x" ele nos mostra a base inteira LDAP.

Pode ser usado em conjunto com samba:
Modify you smb.conf file to call the scripts :
# [...]
add machine script = /usr/bin/ldapaddmachine ‘%u’ sambamachines
add user script = /usr/bin/ldapadduser ‘%u’ sambausers
add group script = /usr/bin/ldapaddgroup ‘%g’
add user to group script = /usr/bin/ldapaddusertogroup ‘%u’ ‘%g’
delete user script = /usr/bin/ldapdeleteuser ‘%u’
delete group script = /usr/bin/ldapdeletegroup ‘%g’
delete user from group script = /usr/bin/ldapdeleteuserfromgroup ‘%u’ ‘%g’
set primary group script = /usr/bin/ldapsetprimarygroup ‘%u’ ‘%g’
rename user script = /usr/bin/ldaprenameuser ‘%uold’ ‘%unew’
# [...]

Instalando o libnss-ldap (muitas vezes isso é instalado no momento da instalação do ldapscripts):
# aptitude install libnss-ldap
Respostas:
host address: IP da máquina
destinguished name ou dn: dc=vivaolinux,dc=com,dc=br
ldap version: 3
login database: no
readable/writable: no
OK

Instalando o libpam-ldap (muitas vezes isso é instalado no momento da instalação do ldapscripts):
# aptitude install libpam-ldap
Make local root database admin: yes
Database requires logging in: no
root login account: cn=admin,dc=vivaolinux,dc=com,dc=br
root passwd: senha do admin
local crypt to use when changing passwords: crypt

Editar o arquivo /etc/nsswitch.conf:
passwd: compat ldap
group: compat ldap
shadow: compat ldap

O restante permanece a mesma coisa.

Agora iremos fazer com que o sistema busque os usuários na base LDAP.
Editar arquivo /etc/pam.d/common-account:
account sufficient pam_ldap.so
account required pam_unix.so
session required /lib/security/pam_mkhomedir.so skel=/etc/skel/ umask=0022
Editar o arquivo /etc/pam.d/common-auth:
auth sufficient pam_ldap.so
auth required pam_unix.so nullok_secure try_first_pass
Editar o arquivo /etc/common-password:
password sufficient pam_unix.so nullok obscure min=4 max=8 md5
password required pam_ldap.so try_first_pass
Editar o arquivo /etc/common-session:
session sufficient pam_ldap.so
session required pam_unix.so

Pronto! Sua base está autenticando no LDAP.

Coloque o schema samba disponível:
cp /usr/share/doc/samba-doc/examples/LDAP/samba.schema.gz /etc/ldap/schema/
gzip -d /etc/ldap/schema/samba.schema.gz

E adicione:
include /etc/ldap/schema/samba.schema
include /etc/ldap/schema/misc.schema

Altere a linha:
access to attrs=userPassword,shadowLastChange
para:
access to attrs=userPassword,shadowLastChange,sambaNTPassword,sambaLMPassword
 

Howto setup Handbrake including GUI from svn in Ubuntu

Link: http://onlyubuntu.blogspot.com/2008/07/howto-setup-handbrake-including-gui.html


First get the medibuntu version of ffmpeg (makes more codecs available),but first remove any old ffmpeg,open a terminal and enter.


sudo apt-get remove ffmpeg

then enter.

sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list

then enter.

sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

then enter.

sudo apt-get install ffmpeg

Next Install the dependencies for Handbrake and the gtk gui.

sudo apt-get update && sudo apt-get install automake build-essential jam libdvdcss2-dev libtool subversion yasm zlib1g-dev libbz2-dev dvdbackup xmlto texinfo g77 gfortran libgtk2.0-dev nasm doxygen libsdl1.2-dev gfortran-multilib gcc-multilib g++-multilib libesd0-dev libgtk1.2-dev libfftw3-dev electric-fence

Next install and build Handbrake.svn and gtk gui (enter each line seperately,it will take some time to build)...

svn co svn://svn.handbrake.fr/HandBrake/trunk HandBrake

cd HandBrake

./configure

make

sudo make install

cd Handbrake/gtk

./autogen.sh

make

sudo make install

HandBrake should be available from the Applications menu under Sound & Video



Dica:
The message tells you what's wrong: "no suitable assembler found. Install yasm" But if you check, you already did, so a quick search in the Ubuntu forums results in a post that states the yasm available in the repo is not a good one. Go to http://www.tortall.net/projects/yasm/wiki/Download to grab 0.7.0 or higher (I grabbed 0.7.1).

Once I did that, HandBrake built just fine. Of course, don't forget to remove the old yasm before installing the newer version.




 

Ubuntu com placa com saída para TV

Link: http://ubuntuforums.org/showthread.php?t=96765

Altere o arquivo /etc/X11/xorg.conf conforme indicado:

Save a backup copy of this file as xorg.conf.back before you do any editing and then edit the following sections:
In the "Module" section comment out these two lines:
#Load "GLcore"
#Load "dri"

and also make sure that the following line is in the "Module" section
Load "glx"

Then Go to the "Device" section and change the following line:
Driver "nv"

to:
Driver "nvidia"

And voila, you've successfully updated the driver to the nvidia driver. In order for this to take effect you'll need to restart the x-server, and if you've changed it properly a pretty NVidia screen should pop up before your login. If you want this screen to go away add the following line to the "Device" section:
Option "NoLogo" "1"

If this doesn't work, you should be loaded automatically into the command line, but if you're just staring at a blank screen hit CTRL+ALT+F1 to exit into the command line and type the following command:
$ cp /etc/X11/xorg.conf.back /etc/X11/xorg.conf

and then restart the x server.

Configuring 2 screens:


First we need to alter the "Device" section by altering the Identifier and adding a screen line:
Identifier "nvidia0"
Screen 0

Then we need to create a second "Device" section:
Section "Device"
Identifier "nvidia1"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 1
Option "TVOutFormat" "SVIDEO"
Option "TVStandard" "NTSC-M"
Option "ConnectedMonitor" "TV"
EndSection

IMPORTANT: make sure that the value of BusID is the same as the value of BusID in the first device section.

For the TVOutFormat and TVStandard values please substitute in the appropriate values (e.g. if you are using composite out then substitute "COMPOSITE" for "SVIDEO" or if you're standard is PAL-B substitute "PAL-B" for "NTSC-M"), for more on this see the nvidia readme appendix J.

What we've done here is divided our nvidia card into two seperate devices that are going to provide picture out to two seperate monitors each running its own screen.

Next we need to change the existing "Monitor" section's identifier to:
Identifier "Monitor0"

and then create a second monitor section for our TV:
Section "Monitor"
Identifier "Monitor1" #TV
Option "HorizSync" "30-50"
Option "VertRefresh" "60"
EndSection

Now that we've set up both of our monitors we need to set up the screens that will be displayed on each. In the existing screen section you'll need to change the identifier, device and monitor lines to match the following:
Identifier "Screen0"
Device "nvidia0"
Monitor "Monitor0"

and then you'll need to add a second screen section for your TV:
Section "Screen"
Identifier "Screen1"
Device "nvidia1"
Monitor "Monitor1"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "800x600"
EndSubSection
EndSection

Make sure that default depth for the TV is the same as the default depth for your other monitor. You may also have to screw around with the modes, 800x600 works for my tv and will probably work for most TVs, but if you have a better TV you may want to try 1024x768 or other resolutions.
The last thing we need to do is set up the "ServerLayout" section so that X knows how to set up your new configuration (Note: keep your own InputDevice settings for this):
Section "ServerLayout"
Identifier "SimpleLayout"
Screen 0 "Screen0"
Screen 1 "Screen1" leftOf "Screen0"

If your TV is to the right of your primary monitor change the leftOf to rightOf. Once you've finished this save your xorg.conf file, make sure your TV is hooked up to your computer and restart. You'll notice that if you watch a movie in full-screen on the TV it doesn't effect your primary monitor at all and you can use your computer to still do whatever you want.

Version Control with Subversion

 

NFS: Overview and Gotchas

Link: http://www.troubleshooters.com/linux/nfs.htm

Para reiniciar NFS digite:
sudo exportfs -a
sudo /etc/init.d/nfs-kernel-server start

Para a montagem segue:
sudo mount -t nfs 192.168.1.10:/export/share /import/share

Cuidado o programa "shares-admin" altera o /etc/exports

Outro How-to: http://ubuntuforums.org/showthread.php?t=249889

Para corrigir problema de internal error com o hardy, veja este patch:
https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/213444

Para resolver firewall e fixar porta veja o link:
http://gentoo-wiki.com/HOWTO_Share_Directories_via_NFS#Modify_EXPORTS

Edite o arquivo:

trocando a linha sobre opções do NFS conforme abaixo para fixar uma porta tcp:
sudo gedit /etc/default/nfs-kernel-server

com esta informação: RPCMOUNTDOPTS='--port 48080'

altere o arquivo sudo gedit /etc/hosts.allow com:
portmap: 192.168.1.0/255.255.255.0
lockd: 192.168.1.0/255.255.255.0
rquotad: 192.168.1.0/255.255.255.0
mountd: 192.168.1.0/255.255.255.0
statd: 192.168.1.0/255.255.255.0

Para confirmar as alterações em sudo gedit /etc/exports utilize o comando
exportfs -a
e depois:
/etc/init.d/nfs-kernel-server restart
/etc/init.d/portmap restart

Alguns comandos interessantes:
strings /sbin/portmap | grep hosts
rpcinfo -p
dpkg-reconfigure portmap

O conteúdo de /etc/exports poderia ser:
/homeserver/Data 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)
/homeserver/aarvati 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)
/homeserver/iarvati 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)
/homeserver/Public 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)
/homeserver/Lixeira 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)
/homeserver/SharedDocs 192.168.1.0/255.255.255.0(rw,no_root_squash,async,no_subtree_check)

O arquivo sudo gedit /etc/fstab pode ficar assim:
server.casa.lan:/homeserver/Data /home/Data nfs users,noauto,rw,hard,intr 0 0
server.casa.lan:/homeserver/aarvati /srv/aarvati nfs user,noauto,rw,hard,intr 0 0
server.casa.lan:/homeserver/iarvati /srv/iarvati nfs user,noauto,rw,hard,intr 0 0
server.casa.lan:/homeserver/Public /home/Public nfs users,noauto,rw,hard,intr 0 0
server.casa.lan:/homeserver/Lixeira /home/Lixeira nfs users,noauto,rw,hard,intr 0 0

Para quem tem nvidia ou ATI existe o pacote abaixo:

Driver Support With Envy
Another very useful tool I’ve found is the Envy tool, which will install required non-free driver support for nvidia or ATI cards for you. I’ll admit that I’ve only used this occasionally, considering I have intel graphics cards on my main laptops, but in the situations where I have needed it things have worked great.
sudo apt-get install envyng-gtk
sudo apt-get install envyng-core
sudo envyng -t
man envyng


Quem esta com interface gráfica tem o comando:
gksu displayconfig-gtk

Removing old deleted mails

With IMAP you can mark emails as deleted and some email clients will not even show them any more. But the emails are still there and occupy space. Usually there is an option to purge all marked emails but many users do not care. So Michael Weisgerber suggests to run this command frequently via crontab to remove such emails:
find /home/vmail/ -name '*,ST' -ctime +7 | xargs rm -f
