If you have copy-paste protected pdf, but you need to copy text, how to remove this kind of security. You need Linux only… and make two commands.
First, convert secured pdf to postscript file.
~$ pdftops secured_file.pdf out.ps
next, convert to pdf back
~$ ps2pdf out.ps converted.pdf
after done, you should have unsecured PDF file. Now you can copy and paste to translate.google.com 🙂
I’d like to describe how simple way to configure polish characters/locale inside terminal.
generate /var/lib/locales/supported.d/local from /usr/share/i18n/SUPPORTED:
cat /usr/share/i18n/SUPPORTED | grep "en\|pl" > /var/lib/locales/supported.d/local
This example shows all polish and english localization. You can find appropriate inside /usr/share/i18n/SUPPORTED file. If you choose add them to list.
generate all localizations
choose your locale:
You can check variables by writing:
In this step you choose langauge of your system and terminal.
How to create mms:// protocol handler in firefox:

2. Right click on the window and choose New, then String from the pop-up menu that appears.

netcat is very useful tool. I will try to describe few examples, how use it.
We can send message to remote host. On first host run nc listen for incoming connections:
nc -v -l -p 3456
- v verbose
- l listen
- p port
On second host:
nc first_host -p 3456
If you write something on first you send text on second and vice-versa.
We can send text, so why don’t send files?
Run nc on first host for listen.
nc -v -l -p 3456 > file
nc first_host -p 3456 < file
Another example – sending via tar pipe
on listening host:
nc -l -p 3456 | tar x
on sending host:
tar cf - * | nc remote_host -p 3456
on listening host we can watch process of the sending file with little program
nc -l -p 3456 |pv | tar x
Of course is is not end of ex. We can use stunnel for encryption these connection, dd for reading partition and sending directly on remote_machine…
We can use netcat as telnet – for checking services and sending text.
echo "GET / HTTP/1.0
"| nc http://www.host.com 80
Like netmap – port scanning
You can scanning port or few ports:
nc -v -i<seconds> -z remote_host <port>-<port>
-i interval in seconds
