Linux adduser user@domain.tld with @ or . inside the userid and use it as an FTP account

If you want to add a new user to your linux box and it not contains any special char like an '@' or '.' there is no problem. In the other case you could not find an answer simply googling around. For this reason i have to make some tests on different kind of server (dedicated and vps ones). 

Via plesk or others gui i didn't find a way to add user with special chars inside the username, also via shell i had some problems with that. 

The final solution for me was using webmin or follow the instructions below:

# groupadd ftpusers
# adduser 1234455 -d /home/1234455 -G ftpusers
# passwd 1234455
# type and retype password
# chown 1234455:ftpusers /home/1234455/

Well, now you have a user without @extdomain.tld so to do that you have to modify two files:

/etc/passwd
/etc/shadow

edit in passwd:

old one
1234455:x:10005:505::/home/1234455:/bin/false
new one
1234455@extdomain.tld:x:10005:505::/home/1234455:/bin/false

edit the same in the shadow and be carefull when do that.

After doing these hacks you could access to your home directory via ftp using 1234455@extdomain.tld :)

[solved] MYSQL Can't start server: can't create PID file: No space left on device

Hi all dear friends of HTV, today i will explain how to fix a bug that affects MySQL server running on a Centos 5.0 Box.

The error in the /var/log/mysqld is :

Can't start server: can't create PID file: No space left on device MYSQL

If your MySQL can't restart and the /var/log/mysqld log show you this message, well, most probably you finished your partition space available.

To solve this issue you have to do the following steps:

1) check your partitions with the command:

df -h

this command will output your partitions conf:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              58G   53G   0  100% //dev/sda1              99M   12M   83M  13% /boot
/dev/sda2              58G   13G   42G  24% /media/sda2


Please notice that the full size of /dev/sda2 partition is 58GB, the used space is 53GB and the available once is 0 (100% use).


2) Now that we are aware of this we have to find the files (often they are huge log files) that fill our partition. So we could take a look in the /var directory or /tmp directory to find and move some of them via rsync into another partition or we could free some space deleting older logs and files not needed. (Be carefully when you are doing that).
To find big files over your system you could execute this command via ssh


 du -h --max-depth=3 /* > mybigfiles.txt


This command will write in the file all the output of the command du -h -max-depth=3 in the file named mybigfiles.txt all showing all the dirs in the system with theirs current size.

Navigating through this file you could find which directories are the biggest ones and after that you have to clean them before restarting MySQL server.

First of all do this command via cmd line:

yum clean all

To empty cached sources and packages in your RH distro.

Then if you would like to remove, for example, all the log files in a dir older then 3 days you have to execute the command :

find /var/log/mydirectorywithbigfiles -type f -mtime +3 -exec rm {}

or use this bash script

#!/bin/bash

find /var/log/mydirectorywithbigfiles -type f -mtime +3 -exec rm {} \;

  

that use a combo of find command and -exec rm {} that removes all the files inside that dir.

After that please execute again the command to check if you freed up some disk space.


df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              58G   13G   42G  24% //dev/sda1              99M   12M   83M  13% /boot
/dev/sda2              58G   13G   42G  24% /media/sda2



Once finished, please restart your Mysqld daemon, via /etc/init.d/mysqld start.

Setup and configure SSL / HTTPS with Verisign CA on Linux CENTOS [step by step tutorial]

If you need to install SSL certificates on your server web you have to follow this step by step tutorial about Verisign's certificate installation. (i get a 30 days trial cert to test it)

1) Install mod_ssl with command:

yum install mod_ssl


2) Create a directory in which we save our key files and move to it

mkdir /home/ssl/
cd /home/ssl/

3) Execute the follow command on a single line:

openssl x509 -req -days 365 -in www.domain_name.com.csr -signkey secure.domain_name.com.key -out www.domain_name.com.crt


4) Copy the key into .secure file.

cp www.domain_name.com.key www.domain_name.com.key.secure


5) Execute the command to generate the file

openssl rsa -in www.domain_name.com.secure -out www.domain_name.com.key

6) Type the following command to generate a private key that is file encrypted. You will be prompted for the password to access the file and also when starting your webserver. Warning: If you lose or forget the passphrase, you must purchase another certificate.

openssl genrsa -des3 -out www.domain_name.com.key 1024


7) You could also create a private key without file encryption if you do not want to enter the passphrase when starting your webserver:

openssl genrsa -out www.domain_name.com.key 1024

Note: i recommend that you name the private key using the domain name that you are purchasing the certificate for ie domainname.key

8) Type the following command to create a CSR with the RSA private key (output will be PEM format):

openssl req -new -key www.domain_name.com.key -out www.domain_name.com.csr

* Note: You will be prompted for your PEM passphrase if you included the "-des3" switch in step 6.

* 2nd Note: When creating a CSR you must follow these conventions. Enter the information to be displayed in the certificate. The following characters can not be accepted: < > ~ ! @ # $ % ^ * / \ ( ) ?.,&

8) Put the output of cat command in a txt file.

cat www.domain_name.com.csr > mycert.txt


9) Copy source from that file mycert.txt and paste it into the Verisign's CSR form validation.

10) wait for the Versign's confirmation email with the browser cert file that will be send to you within 24 hours.


Once you received that email you'll have to download and install the Test Root CA Certificate into your browser. This is the procedure to follow:

11.1) Save the test root CA certificate from Verisign website on a file with .cer extension (ex. browser.cer) and install it into your browser.

11.2) Copy the intermediate CA certificate content from verisign website into a file called (intermediate.crt)

11.4) Copy the certificate that you received with the email in a file called (public.crt)

11.5) Copy the content of the bundle (two cert) into a file ca-cert.crt

-----BEGIN CERTIFICATE-----
MIIEVzCCAz+gAwIBAgIQFoFkpCjKEt+rEvGfsbk1VDANBgkqhkiG9w0BAQUFADCB
.....
-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----
IEVzCCAz+gAwIBAgIQFoFkpCjKEt+rEvGfsbk1VDANBgkqhkiG9w0BAQUFADCB
......
-----END CERTIFICATE-----

11.6) Copy all .crt files (public.crt, intermediate.crt, ca-bundle.crt) into /etc/pki/tls/certs/ on your centos distribution.

11.7) Copy www.domain_name.com.key to /etc/pki/tls/private/ folder

11.8) Now you could check virtual host and insert these lines of code into your /etc/httpd/conf.d/ssl.conf file:


DocumentRoot /var/www/html/yourwebdir
ServerPath /var/www/html/yourwebdir
ServerName www.domain_name.com:443
ServerAlias *.domain_name.com:443
DirectoryIndex index.html index.php index.shtml
ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn
SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW
SSLCertificateFile /etc/pki/tls/certs/public.crt
SSLCertificateKeyFile /etc/pki/tls/private/www.domain_name.com.key
SSLCertificateChainFile /etc/pki/tls/certs/intermediate.crt
SSLCACertificateFile /etc/pki/tls/certs/ca-bundle.crt

SSLOptions +StdEnvVars

SSLOptions +StdEnvVars
SetEnvIf User-Agent ".*MSIE.*" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0

CustomLog logs/ssl_request_log \
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"



12) Now restart apache /etc/init.d/httpd restart


If everything goes [OK] you could check your https and ssl at your web address: https://www.domain_name.com


Good luck!

Add a custom script as a daemon on reboot of a redhat centos server

To enable a custom script in a redhat centos server linux box you have to follow those simple steps.
This is useful when you have to start a server process that don't return anything..
One example is openoffice server aka (soffice).
Suppose you have two files.
The first file A call the second file named B-so
The file A contains a code like this

# Source function library.
. /etc/rc.d/init.d/functions

[ -f /usr/local/sbin/B-so ] || exit 0


prog="B-so"
start() {
echo -n $"Starting $prog: "
daemon /usr/local/sbin/B-so 1> /dev/null 2> /dev/null &
RETVAL=$?
echo
return $RETVAL
}

stop() {
if test "x`ps aux | grep B-so | grep -v grep | awk '{ print $2 }'`" != x; then
echo -n $"Stopping $prog: "
killproc B-so
killall processname
echo
fi
RETVAL=$?
return $RETVAL
}

case "$1" in
start)
start
;;

stop)
stop
;;

status)
status B-so
;;

restart)
stop
start
;;

*)
echo $"Usage: $0 {start|stop|restart|status}"
exit 1

esac

exit $RETVAL


Copy the file A in the directory /etc/init.d/

Copy the second file B.so in the dir /usr/local/sbin/
The file B-so contains a code like this:


. /etc/rc.d/init.d/functions

LOG="/root/mail2fax/log/safe-B.log"


while :
do
...done some stuff ...
done


After that you have to add a line with the path to the service to start in the /etc/rc.local.

Check if permissions on those two files are set on 0755,then you could reboot your server and verify if the service start successfully.

If you use this tool with OpenOffice you could do very intersting different kinds of conversion...

[Solved] DocumentConverter.py via PHP on Linux RedHat Centos

This is a guide to fix the use of PYODConverter on linux RedHat Centos 5 box users.
If you wanna use DocumentConverter.py written by artofsolving, you have to follow those steps.

1)Install openoffice on your linux box or verify installation through commands:
Install Packages

yum install openoffice.org-xxx.

Check Packages

yum list | grep "openoffice".


2)Install python-uno bridge

3)Download DocumentConverter.py

4)Add the following line below "import uno"...

import sys
sys.path.append("/usr/lib/openoffice.org/program")


5)Run openoffice like a service with -headless and -nofirtstartwizard options.


/usr/lib/openoffice.org/program/soffice -nologo -nofirststartwizard -headless -norestore -invisible "-accept=socket,host=localhost,port=8100,tcpNoDelay=1;urp;"




The port 8100 must be the same for client and server obviously.


If you execute this php code



$cmd = "/usr/bin/python /var/www/html/DocumentConverter.py inputfile $outputfile.pdf 2>&1 | tee /var/www/html/mylog.txt"; // tee used to log output and errors of cmd
exec($cmd, $results);
printf("Exec Output: {".print_r($results).";}\n"); //print results of exec command


you'll probably get this error:


[Java framework] Error in function createSettingsDocument (elements.cxx).javaldx failed!
And other permissions problems on tmp dirs.

To solve this, simply add into your php script those lines of code

if (!file_exists("/tmp/ooohomedir"))
{
mkdir("/tmp/ooohomedir");
chmod("/tmp/ooohomedir", 0777);
}
putenv("HOME=/tmp/ooohomedir");

How to make a screencast on ubuntu linux video.

If you wanna be able to do a screencast on linux ubuntu you have to type on your ubuntu's shell:

sudo apt-get install recordmydesktop
sudo apt-get install gtk-recordmydesktop
sudo apt-get install mencoder
sudo apt-get install subtitleeditor
sudo apt-get install avidemux
sudo apt-get install ffmpeg

Then, to capture the video you have to type: recordmydesktop
To stop the video capturing you have to press the combo ctl+c
To run audio/video converter ffmpeg use:
./ffmpeg -vcodec mpeg4 -b 1000 -r 10 -g 300 -vd x11:0,0 -s 1280x1024 test.avi

./ffmpeg --help:
"1000" is the bitrate (increase it to get better quality, but more larger files).
"0,0" tells FFmpeg to record from the top-left cornet of the screen.
"1280x1024" screen resolution, or the window that you want to record.
In that case, you can use xwininfo -frame to get more exhaustive infos about a particular window's coordinates.




If you want to merge files and more other things, likes load multiple video clips, cut and paste portions of video/audio, and save it to an edit decision list (SMIL XML format). Most edit and navigation commands are mapped to equivalent vi key commands. Also, Kino can export the composite movie in a number of formats: DV over IEEE 1394, Raw DV, DV AVI, still frames, WAV, MP3, Ogg Vorbis, MPEG-1, MPEG-2, and MPEG-4 you could use Kino

Few days since the publication of the Ubuntu 8,04 LTS , the gNewSense was published 2,0 whose name in code is deltah.
It could not pass unobserved, the presence of this distro, cause we are supporter of the ideas of the FSF and of the Free Software, rather that of the open Source.
For this cause decided to install gNewSense 2,0 deltah.
The differences between this last and its cousin Ubuntu 8,04.
The beauty of it is that this distro has no copywrited software on it. It's totally free and use only free software.
