EDIT /etc/init.d/rc.local

beressssss

sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 0

or just checking out the value in the /proc system:

cat /proc/sys/net/ipv4/ip_forward
0

As we can see in both the above examples this was disabled (as show by the value 0).

Enable IP Forwarding on the fly

As with any sysctl kernel parameters we can change the value of net.ipv4.ip_forward on the fly (without rebooting the system):

sysctl -w net.ipv4.ip_forward=1

or

echo 1 > /proc/sys/net/ipv4/ip_forward

the setting is changed instantly; the result will not be preserved after rebooting the system.

Permanent setting using /etc/sysctl.conf

If we want to make this configuration permanent the best way to do it is using the file /etc/sysctl.conf where we can add a line containing net.ipv4.ip_forward = 1

/etc/sysctl.conf:
net.ipv4.ip_forward = 1

if you already have an entry net.ipv4.ip_forward with the value 0 you can change that 1.

To enable the changes made in sysctl.conf you will need to run the command:

sysctl -p /etc/sysctl.conf

On RedHat based systems this is also enabled when restarting the network service:

service network restart

and on Debian/Ubuntu systems this can be also done restarting the procps service:

/etc/init.d/procps.sh restart

procedure TForm1.Edit1KeyPress(Sender: TObject; var Key: Char);
begin
  // #8 is Backspace
  if not (Key in [#8, '0'..'9']) then begin
    ShowMessage('Invalid key');
    // Discard the key
    Key := #0;
  end;
end;

autocompletion is literally what it’s name might suggest, you start to type something and it’s completed for you.This is usually enabled for simple things such as file and directory names, and by default it will be activated by the “TAB” key.For example if you wish to look at the system’s password file you might wish to run:

less /etc/passwd

To save keystrokes you can actually type:

lesTAB /eTAB/passTAB

As you proceed to type the words pressing TAB will automatically complete things for you.

In the Debian bash package there is a file installed called /etc/bash_completion, this adds a lot more useful behaviours to bash including:

• Auto completion of hostnames, for SSH
• Auto completion of Debian specific utilities

To cause your shell to use it run the following command, then login again:

echo ‘. /etc/bash_completion’ >> ~/.bashrc

This will now give you a lot more completions, most usefully I find the following :

apt-get upgTAB

This becomes the familiar “apt-get upgrade“, other apt-get, and dpkg commands suddenly understand completion too, so instead of typing “dpkg --search” you can cut this down to “dpkg --seaTAB“.

To be honest I don’t know the full extent of the completion offered as some of the code in the /etc/bash_completion file is pretty hard to follow, but I know it saves me time.

Why not have a look yourself?

$sudo apt-get install msttcorefonts

Ini hanya akan menginstall font standar yang telah disebutkan di atas. Apabila anda ingin menginstall font lain, caranya cukup copy font anda ke directory

~/.fonts/

Setelah selesai menginstall / copy font, LogOut atau restart komputer anda. Atau apabila anda tidak ingin merestart komputer, cukup ketikkan kode di bawah pada konsole :

$sudo fc-cache -fv

selamat mencoba

HTTP proxy server forbids port 5050 tunneling

Untuk mengatasinya, lakukan langkah2 berikut ini :

1. Buka file konfigurasi squid (/etc/squid/squid.conf)

2. Cari baris “acl CONNECT method CONNECT”

3. Tambahkan baris berikut ini :

acl port_saya port 5050

http_access allow CONNECT port_saya

4 . Tutup SQUID.CONF

5. Restart service SQUID (/etc/init.d/squid restart)

6. Set proxy di pidgin, dengan tipe HTTP

7. Selesai, Pidgin siap digunakan
