IP TABLE MODULE LOAD ISSUE ON OPENVZ

ftp connection to the server failed and it will throw an error like

[ajeesh@tech24 ~]$ ftp ftp.yourdomain.com
Connected to ftp.yourdomai.com (IP).
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 50 allowed.

Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
227 Entering Passive Mode ()
ftp: connect: Connection timed out

Solution:-

pure-ftpd you could add the port range 30000:35000 to TCP_IN and add the following line to /etc/pure-ftpd.conf and then restart pure-ftpd:

PassivePortRange 30000 35000

after that we need to enter the port range 30000:35000 on /etc/csf/csf.conf on the line ' TCP_IN = ' [Allow incoming TCP ports]

This will fix my issue

Related issue also fixed
*WARNING* Since the Virtuozzo VPS iptables ip_conntrack_ftp kernel module is currently broken you have to open a PASV port hole in iptables for incoming FTP connections to work correctly. See the csf readme.txt under 'A note about FTP Connection Issues' on how to do this if you have not already done so.

Testing ipt_recent...FAILED [Error: iptables: Unknown error 18446744073709551615] - Required for PORTFLOOD feature


=====================
To activate passive mode in Firewall Pf and FTP server PureFtp.
1. First we need to check the conf of pureftp PassivePortRange
Suppose it is 30001 32000
2. open your pf configuration file /etc/pf.conf and enter the following rule
pass in on $ext_if proto tcp from any to any port 30000 >< 32001 keep state
3. ipf -Fa -f /etc/ipf.rules;sleep 40;ipf -Fa :- for testing the firewall for 40 sec
4. if step 3 is ok then reload your pf firewall : ipf -Fa -f /etc/ipf.rules

FFmpeg FFmpeg-PHP Mplayer Mencoder flv2tool LAME MP3 Encoder INSTALLATION

Here We can discus how to install FFMPEG and it associated friends ( Supporting Software) on Linux Servers.
FFmpeg
FFmpeg-PHP
Mplayer Mencoder
flv2tool
LAME
MP3 Encoder

****************

For Installing FFMPEG and its friends we need to make sure the following packages already installed on your server
gcc,gmake,make, libcpplibgcc, libstdc++, gcc4, gcc4-c++, gcc4-gfortran, subversion, ruby ncurses-devel -y

If not please install these packages using yum
yum install gcc gmake make libcpp libgcc libstdc++ gcc4 gcc4-c++ gcc4-gfortran subversion ncurses-devel -y
Install Ruby, Ruby Gem, Fastthread, Mongrel and Rails on cpanel servers by using the command
/scripts/installruby
Please do the following Steps

cd /usr/local/src/

Next We need to Download the required MODULES .
wget www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
wget rubyforge.org/frs/download.php/9225/flvtool2_1.0.5_rc6.tgz
wget easynews.dl.sourceforge.net/sourceforge/lame/lame-3.97.tar.gz

wget superb-west.dl.sourceforge.net/sourceforge/ffmpeg-php/ffmpeg-php-0.5.1.tbz2
Or
wget http://space.dl.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2

wget downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
wget downloads.xiph.org/releases/vorbis/libvorbis-1.1.2.tar.gz

and wget http://www.tortall.net/projects/yasm/releases/yasm-0.7.0.tar.gz

After that extract these downloaded MODULES using ' tar zxf filename '

mkdir /usr/local/lib/codecs/

By using Subversion we can down load packages for FFMPEG and Mplayer
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
cd /usr/local/src/mplayer

svn update

PS: Please note that now the SNV version has been not updated for a long time so it is good to use git installation instead of SNV: 19-08-2011(Firday)
cd /usr/local/src/
mv /usr/local/src/essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

After that We can install one by one packages

LAME:-
cd /usr/local/src/lame-3.97
./configure
make && make install

LIBOGG:-
cd /usr/local/src/libogg-1.1.3
./configure --enable-shared && make && make install

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

LIBVORBIS:-
cd /usr/local/src/libvorbis-1.1.2
./configure && make && make install

FLVTOOL2:-
cd /usr/local/src/flvtool2_1.0.5_rc6/
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

MPLAYER:-
cd /usr/local/src/mplayer
./configure && make && make install

FFMPEG:-
cd /usr/local/src/ffmpeg/
./configure --enable-libmp3lame --enable-libvorbis --disable-mmx --enable-shared
make
make install

export LD_LIBRARY_PATH=/usr/local/lib/

ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51
ln -s /usr/local/lib/libavdevice.so.52 /usr/lib/libavdevice.so.52
ln -s /usr/local/lib/libavformat.so.52 /usr/lib/libavformat.so.52

FFMPEG-PHP Extension:-
cd /usr/local/src/
wget http://sourceforge.net/projects/ffmpeg-php/files/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2/download

[0.50 version throws me error once i have used this version fixed my error]

tar -xjf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0/
phpize
./configure
make
make install

make install will shows you the extension file directory for ffmpeg.so. This Exension should be include in your php.ini file

extension=/usr/lib/php/extensions/no-debug-non-zts-20090626/ffmpeg.so

Finally Restart Appache
service httpd restart

Veryfy: Create a info.php file (ie,) and verify this module is loaded or not.

While compiling ffmpeg-php Error:ffmpeg_frame.c:421: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)

***********************
update ffmpeg_frame.c and replace every instance of PIX_FMT_RGBA32 with PIX_FMT_RGB32

vi ffmpeg_frame.c

:%s/PIX_FMT_RGBA32/PIX_FMT_RGB32

:w :q!

Solve my issue

**********************
# ffmpeg -v
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

Fix:
location of these libraries is /usr/local/lib/ such as /usr/local/lib/libavdevice.so.52 .

ln -s /usr/local/lib/libavdevice.so.52 /usr/lib/libavdevice.so.52
ln -s /usr/local/lib/libavformat.so.52 /usr/lib/libavformat.so.52
etc ... like we done for ibavformat.so.50

Or we can fix by

/etc/ld.so.conf.d/libc.conf open with your favourite editor and include this line /usr/local/lib

if /etc/ld.so.conf.d/libc.conf not there create one called /etc/ld.so.conf.d/ffmpeg.conf (or even libc.conf) and add the line /usr/local/lib in it, then run sudo ldconfig -v.


Iam Expecting some valuable suggestions on this posting
 *******

Error :   [STDERR] PHP Warning: Module 'ffmpeg' already loaded in Unknown on line 0

This seems you have multiple entries for ffmpeg.so extension on your php.ini file. So you need to check this file and remove the unwanted extension for ffmpeg.

nest step please kill that process and re-execute your yum install again

This solve my yum install issue

RvSiteBuilder

Fatal error:

The license file /var/cpanel/rvglobalsoft/rvsitebuilder/rvsitebuilder.lic has expired. in Unknown on line 0

For fixing the issue do run the following commands
root@server1 [~]# rm -f /var/cpanel/rvglobalsoft/rvsitebuilder/var/INSTALL_COMPLETE.php
root@server1 [~]# rm -f /var/cpanel/rvglobalsoft/rvsitebuilder/rvsitebuilderversion.txt

# /scripts/makecpphp [It just rebuilds the copy of PHP that cPanel and WHM use (not your public version of PHP) and then makes sure that cPanel and WHM are set to use that version.]

Last
#Go to root WHM/RVSiteBuilder, it will automatically rebuild the database for you.

PHPMYADMIN

1. PHPMYADMIN is not showing the database which are creating

But while checking the databases through WHM/MYSQL you can see these data bases are available for that particular user.
Ans:- Please check the user privileges and grant the privilege for that user
Check the database username and cpanel user name are same or not. Most probably it is due to this issue (may be user cpanel user name is a invalid one like "."symbol something) so we need to change username in WHM.

COMMON TOOLS

1. Pidgin

in default linux (fedora) pidgin is there.
#yum install pidgin*
#yum update pidgin*

pidgin-guifications-2.16-4.fc12.i686 --> It is a Pidgin plugin that displays popups display if user writing a message , user log out/login etc ..

#yum install pidgin-guifications-2.16-4.fc12.i686
