pdf2svg on Centos 6.2 (powerfull toy)

To understand about pdf2svg, please visit author site on cityinthesky.co.uk and download the latest source code to compile, in my case it is pdf2svg-0.2.1.tar.gz And follow instruction there to compile the source code,
Extract it

tar -zxvf pdf2svg-0.2.1.tar.gz

Go to extracted directory

cd pdf2svg-0.2.1

Do configure

./configure --prefix=/usr/local

And make

make

in this step im not so successful, there is warning like this

pdf2svg.c:152: warning: incompatible implicit declaration of built-in function ‘free’

BUT i ignore it, just try my luck :D Final step is

make install

And check

which pdf2svg

giving me result

/usr/local/bin/pdf2svg

How to use Simple enough, just follow author website example (again)

pdf2svg pdf_testpage.pdf pdf_testpage.svg

now you can open pdf_testpage.svg on inkscape with all converted fonts (Yes !!! converted) and save it as eps file to open using Adobe Illustrator.

Postfix + Dovecot on Centos 6.2 Final Release

Important, first you must read the /tmp/iRedMail-0.8.3/iRedMail.tips, on the first installation I've not read it at all, but after got some trouble i came back to read it :D

$ cat /tmp/iRedMail-0.8.3/iRedMail.tips

Finish ??? Not Yet We must update bind configuration with Domain Keys Indentified Main (DKIM), now open your console again.

$ amavisd show keys

Or, if the above command complain about config file, "Config file "/etc/amavisd.conf" does not exist, at /usr/sbin/amavisd line 1799." you can use command below.

$ amavisd -c /etc/amavisd/amavisd.conf showkeys

In my case, the output loook like this

$ amavisd -c /etc/amavisd/amavisd.conf showkeys
; key#1, domain anekarupatera.lan, /var/lib/dkim/anekarupatera.lan.pem

Now test your DKIM key, it should be pass right now.

# amavisd -c /etc/amavisd/amavisd.conf testkeys
TESTING#1: dkim._domainkey.anekarupatera.lan => pass

Final check, Make sure you have /var/www/awstats/awstats.pl on /var/www/awstats/ directory, if you don't have it, you must create it using command below.

ln /usr/share/awstats/wwwroot/cgi-bin/awstats.pl  /var/www/awstats/awstats.pl

Now reboot your linux.

After Reboot :

TigerVNC on CentOS 6

According to the Tigervnc wiki, TigerVNC is a high-performance, platform-neutral implementation of VNC (Virtual Network Computing), a client/server application that allows users to launch and interact with graphical applications on remote machines. TigerVNC provides the levels of performance necessary to run 3D and video applications, and it attempts to maintain a common look and feel and re-use components, where possible, across the various platforms that it supports. TigerVNC also provides extensions for advanced authentication methods and TLS encryption.

To install TigerVNC, follow this step.

1. Create the repository config file /etc/yum.repos.d/slce.repo:

[slce]
name=Scientific Linux Cyrillic Edition
baseurl=http://downloads.naulinux.ru/pub/SLCE/6x/$basearch/CyrEd/RPMS/
enabled=0
gpgcheck=1
gpgkey=http://downloads.naulinux.ru/pub/SLCE/RPM-GPG-KEY-linux-ink

2. Install tigervnc-server rpm package:

# yum --enablerepo=slce install tigervnc-server

3.Create VNC user

As root :

# useradd lombok
# passwd lombok

4.Set VNC's user password

Switch user into the account for each user, and run: vncpasswd This will create a .vnc directory.

[~]# su - lombok
[~]$ cd .vnc
[.vnc]$ ls
passwd
[.vnc]$ exit
[~]#

4. Edit the server configuration

Edit /etc/sysconfig/vncservers, and add the following to the end of the file.

VNCSERVERS="1:lombok
VNCSERVERARGS[1]="-geometry 800x600"

5. Edit your iptables

6. Start the VNC Server

# /etc/init.d/vncserver start

7.Testing VNC Server

As user lombok :

# vncserver :1

At this point, your server is ready to accept connection from another computer.

Connect to TigerVNC Server

Start VNC Viewer Client, because vncserver starting at display 1 (vncserver:1) you must connect using IP:display_number, in this case : 192.168.110.75:1

Just enter user lombok password and press OK

And....

Optional

Another Option fow VNC Viewer is TightVNC Java Viewer version 2.5.0

Enter user lombok password and press login.

End.

X11vnc on Centos 6.0 (insecure connection)

Installing X11vnc

Often you will need remote access to an already logged in GUI session on a "real" console. Or you will need to help another user remotely with an GUI or visual issue. You will need either "vnc-server" or "x11vnc". The vnc-server option will be a module added to X11 for "allways on" vnc support, while x11vnc will allow for adhoc vnc support. vnc-server install will require no third party repos or source building.

x11vnc is a way to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows.

1. Download the latest rpm install from http://dag.wieers.com/rpm/packages/x11vnc/ to the host you want the vnc-client to connect to:

[root@edp-01 ~]# wget http://dag.wieers.com/rpm/packages/x11vnc/x11vnc-0.9.3-1.el5.rf.i386.rpm

2. Install, as root, via the yum or rpm programs on the host you want the vnc-client to connect to:

[root@edp-01 ~]# rpm -ivh  x11vnc-0.9.3-1.el5.rf.i386.rpm

Or

[root@edp-01 ~]# yum install x11vnc-0.9.3-1.el5.rf.i386.rpm

Configuring firewall option

The iptables rules in /etc/sysconfig/ need to be amended to open the VNC ports; as needed, if a local ipv6 setup is being used, those need to be amended as well: 

[root@edp-01 ~]# mcedit /etc/sysconfig/iptables

add folowing line to the iptables file :

-A INPUT -m state --state NEW -m tcp -p tcp -m multiport --dports 5900:5903,6001:6003 -j ACCEPT

So it look like : 

[root@edp-01 ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp -m multiport --dports 5900:5903,6001:6003 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT ... and then restart the iptables:

[root@edp-01 ~]# /etc/init.d/iptables restart

Starting x11vnc

Start the x11vnc process on the host you want the vnc-client to connect to. Please take a long look at the possible options from the x11vnc website. A very simple/insecure example for a trusted network setup (local network or VPN) is to have the user with the GUI console issue the command:

[root@edp-01 ~]# x11vnc -nopw -display :0.0

Accessing x11vnc

Install VNC viewer on client computer next. Download from the site below to install. http://www.realvnc.com/products/free/4.1/download.html Start VNC viewer after installing. Then following scrren is shown. Input [(Server's hostname or IP address):(display number)] like following example.

Just choose continue if you asked for encrypted connection.

 

And the result is:

 

End
