Reinstall all the packages that we used in our previous Ubuntu linux box (it also applies to Debian, etc.) can be a long, then maybe it is not said that we remember everything we used to, especially if they are full of facilities development of libraries or servers installations. To reinstall all the packages on the new boxes, but we can do everything with a few simple commands.

To generate the list of installed packages in your ubuntu linux box:

  dpkg - get-selections> installed-software 

To check and re-install all packages on your list, ubuntu linux box on the target:

  dpkg - set-selections <installed-software 

Finally, type the command

  dselect 

http://software.virtualmin.com/gpl/debian/dists/virtualmin-etch/main/binary-i386/

install the package with a simple: sudo dpkg-i-wrapper_1.0 procmail-2_i386.deb

Then you should check the permissions of the resi procmail-wrapper that you can find in / usr / bin:
rwsr-xr-x 1 root root 2.9K 11/28/2006 10:08 procmail-wrapper
actually it should already be ok after installation. In particular, if s does not appear in the user permissions you will have problems.

Finally we verify that postfix uses procmail our wrapper and not in a direct manner:

sudo nano / etc / postfix / main.cf

ensure that there is the following directive:

mailbox_command = / usr / bin / procmail-wrapper-o-a $ DOMAIN-d $ LOGNAME

To enable support PCNTL in php5 (tested on Ubuntu 10.10) in the first place you need to install php5-cli php5-dev, and, of course you must satisfy all the dependencies required by the system:

# Sudo apt-get install php5-dev php5-cli

After we have to put in the path where you can find the source of the module you intend to compile:

# Cd / etc/php5/cli/php5-5.3.3/ext/pcntl

The path may be different, depending on the distro and version of php (/ etc/php5/cli/php5-xxxxx/ext/pcntl). But after we go to the final steps:

# Phpsize

#. / Configure

# Make

# Make install

Alternatively you can also make install to copy by hand the module you just compiled:

# Cp modules / pcntl.so / usr/lib/php5/shared_location_modules

Finally add the. Php ini to load our form to:

# Echo "extension = pcntl.so"> / etc/php5/conf.d/pcntl.ini

Do not forget to restart apache then to apply our changes:

# / Etc/init.d/apache2 restart

If Ubuntu Server after you install and configure webmin + VirtualMIn there appears the error:

The procmail procmail command has 0 permissions, When It Should Be setuid and setgid to root. Email delivered or not may be properly checked for spam.

You can fix by following these steps:

1. Make sure that the postfix configuration file / etc / postfix / main.cf contains the following line:
   mailbox_command = / usr / bin / procmail-a "$ EXTENSION"
   if it appears: mailbox_command = procmail-a "$ EXTENSION" should be amended with the absolute path as above.
2. Change the group membership of / usr / bin / procmal from "mail" to "root." Chgrp root / usr / bin / procmail
3. Finally, set the following permissions procmail executable: chmod 6755 / usr / bin / procmail

Here are some links from which to get ideas for a better series, but in my case these three steps have solved the problem, tested on Ubuntu Server 10.04 and 10.10.

Needless to say, many have already made ​​the leap to version 8.04 of Ubuntu, so this little tips will be useful for users of VMWare and in particular users through the VMWare Server Console. Who tried to install the Console has encountered problems in all probability not find libraries at launch the application:

$ Vmware-server-console

Can be solved easily with the following commands:

$ Sudo ln-sf / usr/lib/libpng12.so.0
/ Usr/lib/vmware-server-console/lib/libpng12.so.0/libpng12.so.0

$ Sudo ln-sf / usr/lib/libgcc_s.so.1

Link to original source

On Ubuntu, Debian, but there is also a handy Python script youtube-dl. After making sure that you have installed the package just type the following link to the movie itself. The video is saved in. Flv, already viewable, but for those who want to just call with the appropriate parameters for ffmpeg to convert the video into a format DivX or XviD.

In summary:

# Sudo apt-get install youtube-dl

# Youtube-dl http://www.youtube.com/watch?v=TsNBs-iF590

# Ffmpeg-vcodec xvid-i video.flv-acodec mp3 video.avi

Optional but useful options for the conversion of the video:

-B video bitrate (default = 200)
-Ab audio bitrate (default = 64)
-Ar sample rate (default = 44100)
-S frame size (default = 160 × 120)

In this post we found an interesting article that helps us understand how to customize the image. ISO of Ubuntu. Every need is good, the sysadmin who wants their picture to streamline the work of everyday people who want to add or remove paccketti and functions of the Linux box.
