PDF Split and Merge Utility for Ubuntu Linux PDF Sam

If you deal with a lot of PDF files under Ubuntu and all you want is nothing but to extract certain pages... then you dont need PDF Sam, PDFMod should do it for you. But if you want more control over your PDF documents (meaning both split and merging with advanced features) then PDF Sam is a pretty good utility.

PDF Sam is an open source application written in Java and needs the Java virtual environment to run. It comes with two versions (both open source). One version is completely free (the one that Im using) but for the commercial version (they called it enhanced version), for that youll have to pay some fee.

Theres no "fee limits", even a single dollar will do it! OR you can download the enhanced versionss source code and compile it for free as well.

Not the best looking GUI... but it gets the job done!...

But the enhanced version has its own features such as the ability to encrypt or decrypt PDF files, add a front-page, etc. But for simple split/merger needs, the free version is more than enough. 

Main features...

*. Split PDF files with following options (few to mention):


Split the source file into single pages, manually define the starting page, split after a certain pages (1/2/ any page numbers) or use bookmarks as split points, change the output file meta data (Acrobat 6/7/8 or use the source meta data), change the output file location, etc.

You can add more than one PDF file to the list.

*. Merge is pretty simple actually.


You just locate/add your files to the list and then change few settings such as the above mentioned meta-data version, destination (enable "PDF documents contain forms" option if needed) and hit the "Run" button.

*. Play alert sounds (dont think it worked in my Ubuntu 11.04 though).

*. Few languages supported.

Although default GUI is pretty darn ugly :D, I changed it using the "Settings" section (youll have to re-start the app to apply the changes) and after that PDF Sam used the default GTK theme (an older version of the GTK actually) and it looked much nicer afterward.

You can install PDF Sam in Ubuntu 11.04 Natty Narwhal (perhaps in 10.10 and 10.04) by using the below command in your Terminal window.

sudo apt-get install pdfsam

Thats it.

PERMASALAHAN TIDAK DAPAT LOGIN WEBHTB DI UBUNTU SERVER

Sempat pernah hampir install ulang webhtb dan ubuntu server gara-gara gak dapat login ke webhtb. Perasaan password nya uda bener tapi kok gak bisa login ya...?
Hmmmmm.. Ternyata masalahnya karna ubah-ubah port ssh nya..
Bagi rekan-rekan sekalian yang port default SSH dirubah dan tidak bisa
menggunakan webhtb, syukur
allhamdulillah, saya berhasil
ngoprek, nih trik-nya: file2 PHP yg berada di folder /var/
webhtb/Net/
ubah baris pada
file yg bersangkutan : file SSH1.php >>>
function Net_SSH1($host, $port = 22, $cipher = NET_SSH1_CIPHER_3DES) file SSH2.php >>>
function Net_SSH2($host, $port = 22) angka 22 boleh diubah
untuk disesuaikan dengan port SSH
yg sedang berjalan.
Dan hasilnya...
Bingo...

Trims buat para master ubuntu..
Maaf bila terdapat kesalahan..
Namanya juga masih awam..
Hihihi..
Salam salaman dari agus wiana.

PORTSENTRY SEBAGAI PINTU KEAMANAN JARINGAN ANDA DAN KONFIGURASI NYA DI LINUX UBUNTU

SERVER LINUX DAN KONFIGURASI PORTSENTRY


Yang di bahas disini adalah bagaimana caranya mengamankan server liux dengan menggunakan portsentry. Program ini bersifart gratis yang memiliki licensi GPL. Portsenty merupakan tools yang digunakan untuk menghindari berbagai aktifitas scaning oleh hacker ataupun semacamnya. Portsentry akan membuat server kita seolah-olah menghilang bila terjadi aktifitas scaning dan juga dapat memblok ip address hacker tersebut.

Berikut konfigurasi nya, hal ini saya lakukan dengan menggunakan mesin ubuntu 10.10
install terlebih dahulu portsentry
#apt-get install portsentry

setelah terinstall lakukan sedikit perubahan
#nano /etc/portsentry/portsentry.conf


cari baris
#BLOCK_UDP="1"
#BLOCK_TCP="1"


ubah menjadi
BLOCK_UDP="1"
BLOCK_TCP="1"

dan pastikan pada baris berikut ini aktif
KILL_Route=”/sbin/route add -host $TARGET$ reject”

kemudian aktifkan portsentry
#/etc/init.d/portsentry start

untuk melihat ip target yang melakukan scaning atau ip yang di blokir
#tail -f /var/log/syslog
#tail -f /etc/hosts.deny

Dan untuk membuka ip yang diblokir oleh portsentry adalah membuang ip scanner (ip Yang terbokir) dari /etc/hosts.deny

Restart service portsentry nya
#/etc/init.d/portsentry stop
#/etc/init.d/portsentry start

Jika ingin membut whitelist (ip yang diabaikan oleh portsentry) dapat memasukan ip nya kedalam file yang ada pada :
/etc/portsentry/portsentry.ignore

untuk melakukan scaning ip nya dapat menggunakan nmap

Special thanks to all master ubuntu
