FileZilla Server: Implicit SSL part 2
On a local network FTP works just fine however when connecting to the Internet you need to consider a user (FTP client) more importantly the mode of transfer, active or passive. Everything is geared to make it easier for the client hence your server must support passive mode. The following covers this mode and the added complication of running a FTP server behind a wireless router with NAT.
FTP Basics
FTP uses two ports, a 'command' (control) port and 'data' port traditionally these are assigned ports 21 and 20 respectively. Depending on the operating mode, the data port is not always on port 20. Most browsers use passive mode for connection this mode changes the data port as follows.
Top
Passive FTP
In passive mode a client initiates both connections to the server. A client first opens two consecutive random unprivileged ports (ports above 1023). The first port contacts the server on port 21, and issues the “PASV” command. In response the server opens a random unprivileged port and sends the “PORT P” command back to the client. The client then initiates the connection from it’s second port to transfer data.
A secure FTP server follows the above procedure with one minor difference the command port used is reserved port 990.
What’s important when using a NAT device is the need to forward ports 20, 21, 990 and all unprivileged ports. In reality unprivileged ports are restricted to a small range for example 50000 to 50100.
During a data transfer the FTP server needs to send its visible IP address back to a client. Because of address translation through a NAT device the FTP servers has no way of determining this IP address. It needs to be set during FTP server configuration, not a problem if you have a fixed IP address however a dynamic IP is problematic.
The FileZilla team neatly resolves this issue by providing a dynamic IP address resolution service.
Top
Active FTP
If you have ever set-up an FTP client behind a NAT (Network Address Translation) router you will have been forced to changed mode from active to passive. Reason for this, active FTP will not work behind a NAT device.
Top
Summary
The above is intended to explain why you need to twiddle certain settings and how to choose options for your installation. All settings for passive mode are on a single page making the whole set-up process easier.
Top
Configure Passive Mode
1. Start the server by double clicking on filezila_start.bat
2. Start the administration interface, double click on filezilla_admin.bat
3. Select Edit > Settings
4. A) Select Passive mode settings
5. B) Default: Select this if directly connected to the Internet.
6. C) Use the following IP: If connected to the Internet via a NAT router and you have a fixed IP address enter it here.
7. D) Retrieve external IP address from: If connected to the Internet via a NAT router and you have a dynamic IP address select this radio button. Enables FileZilla’s dynamic IP address resolution service
8. E) Don’t use external IP for local connection. Default is checked, no need to change this.
9. F) Use custom port range: Check this box to enable, we do need to restrict the range of random ports. This also restricts (minimises) the ports that require forwarding in the router.
10. G) Enter range of ports you want to allow, 50000-50100 is reasonable. Allows 100 ports consider reducing this if you do not expect a high number of simultaneous connections.
11. H) Click OK

Configure NAT Router
You need to forward ports 20, 21, 990 and the range (50000-50100) to your PC’s IP address (192.168.1.6)
Replace the values in brackets with your own.
There is a vast range of routers hence I have not provided any detailed set-up instructions.
Again I point you to PortForwrd a website dedicated to this topic with detailed instructions how to forward ports on most routers.
When setting up your router, example shown on the right hopefully provides a clue what to look for.

FileZilla Server: Implicit SSL part 1
Implicit SSL
Due to the number of steps required setting up a secure FTP server is relatively difficult because of this I have split this over two pages. The procedure is incremental first create a server certificate ensure it runs on a local network and finally configure for Internet access.
Server certificate
FileZilla has a built in certificate generator making this process very easy.
Enable SSL support:
1. Start the server by double clicking on filezila_start.bat
2. Start the administration interface, double click on filezilla_admin.bat
3. Select Edit > Settings
4. From the left menu clcik on SSL/TLS settings A)
5. Check Enable SSL/TSL support B)
6. Default Allow explicit SSL/TLS on normal connections C)
7. Checks Force explicit SSL/TLS D)
8. Default Listen for SSL/TLS –only connections on port 990 E)
9. Click Generate new certificate F)
Note: No need to fill in Private key or Certificate files or Key password boxes.
Fill in certificate details:
11. Seclect Key size 4096bit G)
12. Insert 2-Digit country code H)
13. Fill in some real or dummy information a)-f)
14. Fill in Common name I) Use localhost or your real domain name
15. Use browse J) and navigate to folder *\udrive\filezilla_server
this is where the certificate will be saved.
16. Click Generate certificate K) this will take a while.
17. When complete click OK L)
Enable user to use SSL:
18. From admin select Edit > Users
19. Select a user account M)
20. Check Bypass N)
21. Check Force SSL for user login O)
22. Click OK P)
23. Restart server
Client
I am assuming your are using FireFox and FireFTP
1. Enter a host R) either use IP address 127.0.0.1 or host name localhost
2. Enter an Account name Q) Can be anything you like.
3. Enter login name S) e.g fred (ftp user name)
4. Enter password T) for fred (ftp user account password)
5. Click on Connection tab U)
6. From the drop down menu V) select Implicit SSL (Good)
7. Check the port number 990 is set W)
8. Finally click OK X)
Local test:
From FireFTP click the Connect button enter name an password.
Your browser will have a whinge, create a certificate exception.
FTP folder will display.
Local network test:
On another PC connected to your network repeat the above steps 1-11.
Note: At step 1 enter your PC’s IP address. (See previous page how to obtain IP address)
That confirms you can access the FTP server across your network.

[Solved] Error 1606: Could not access network location 0\” in windows Xp
The error was faced by one of our readers who was irritated with the problem that whenever he tried to install or uninstall any program there comes an error message reading “Error 1606:Could not access network location 0\”
Well the fix is not that difficult but requires some Registry Tweaking so it would be better if you have a backup of your registry, but if you are confident enough then you can do it without that as well.
Steps:
1. Type regedit in the Run box to open the registry editor.
2. Now navigate to HKEY_CURRENT_USER -> Software -> Microsoft -> Windows -> Current Version -> Explorer -> User Shell Folders
3. Locate the key named “Recent” in the right side and delete it by right clicking on it.
4. Windows may require a restart.
The problem would have gone but if it hasn’t then have a look at these MS articles.

Installing LAMP on Ubuntu 10.04 and 10.10
If you're developing websites, it's nice to be able to test your code in the privacy of your own computer rather that out in the public internet. In order to do that, you'll need to install a webserver on your development computer. LAMP (Linux, Apache, MySQL, php) is one of the most common web hosting platforms, so it's a perfect environment for you to build and test your website code. If you carefully follow these step by step instructions, you'll have your own LAMP setup running in no time.
Install LAMP on Ubuntu
The Ubuntu developers have made it easy to install the LAMP server packages with a single command. Simply open a terminal window and enter the following.
sudo apt-get install lamp-server^
No, that's not a typo. Please make sure to include the caret (^). The command will not work without it.
sudo apt-get install lamp-server^
The apt package manager will show all the packages that need to be installed. Hit to confirm that you want to install them.
LAMP packages
You will then be prompted to change the password for the root user on the MySQL database.
Set MySQL root password
Enter the password you want. You'll be prompted to enter it a second time to confirm.
After you confirm your password, apt will continue to install the rest of the packages.
Congratulations, your LAMP installation is now complete! That was the easy part, now you need to get a few things configured to make your system easy to work with.
Test Apache
Open a web browser and enter the address http://localhost/. You should see a web page that says "It Works!"
Testing Apache
Test php
Now that you know Apache works, you'll want to test the php installation. You'll need to create a file in /var/www called testing.php. Open a terminal and enter:
sudo nano /var/www/testing.php
Enter the following line into the text editor, save the file and exit.
Next, restart Apache with the following terminal command:
sudo /etc/init.d/apache2 restart
Now go back to your web browser and enter the address http://localhost/testing.php/. You should see a page displaying version information for your php installation.

Configure MySQL
Since I'm installing LAMP for a web development environment, I want the MySQL database to be bound to the localhost IP address. This should be 127.0.0.1 for your system. You can verify it with this terminal command.
cat /etc/hosts | grep localhost
You'll now want to verify that the correct bind address is set up in MySQL's my.cnf file.
cat /etc/mysql/my.cnf | grep bind-address
You should see a line that looks like this:
bind-address = 127.0.0.1
If the IP address doesn't match the one for your system, you'll need to edit the my.cnf file to correct it.
Install phpMyAdmin
You don't need to install phpMyAdmin, but it's a much easier way to get in and adjust things in your MySQL database if you're not familiar with MySQL's commands. You can install phpMyAdmin from the command line with:
sudo apt-get install libapache2-mod-auth-mysql phpmyadmin
The installation will prompt you to select a web server for automatic configuration.
phpMyAdmin Setup
This is important! Use the space bar on your keyboard to select apache2. Make sure there's a * next to apache2 like the picture below and then hit. (Click the picture to enlarge it and see what I'm talking about.)
phpMyAdmin Setup: select apache2
The next screen will explain some information about database configuration. Hit the key to move on.
phpMyAdmin database config
Another screen will come up asking if you want to configure a new database called dbconfig-common. Since this is a fresh installation, use the key to select Yes and hit .
phpMyAdmin dbconfig-common
You'll be prompted next to enter the MySQL root password. Enter the MySQL root password that you created earlier, hit to select Ok and hit .
MySQL root password
You'll then be prompted to enter a MySQL application password for phpmyadmin. You can hit and a random password will be generated. I chose to use the same password that I used for the root MySQL password.
MySQL application password
If you enter your own password, a password confirmation screen will come up. Confirm your password.
MySQL application password confirmation
Your phpMyAdmin installation and configuration is now complete.
Testing phpMyAdmin
Open your web browser and enter the address http://localhost/phpmyadmin/. You should see a page like this.
phpMyAdmin log in
You can log in with the username root and the root password that you created earlier.
Logged into phpMyAdmin
Congratulations, you're now ready to start building your local website. If you're only working on one site you can put all of your files into /var/www. If you'll be working on multiple sites you may want to consider some additional Apache configuration to keep things neat and clean on you system.
Install LAMP on Ubuntu
The Ubuntu developers have made it easy to install the LAMP server packages with a single command. Simply open a terminal window and enter the following.
sudo apt-get install lamp-server^
No, that's not a typo. Please make sure to include the caret (^). The command will not work without it.
sudo apt-get install lamp-server^
The apt package manager will show all the packages that need to be installed. Hit
LAMP packages
You will then be prompted to change the password for the root user on the MySQL database.
Set MySQL root password
Enter the password you want. You'll be prompted to enter it a second time to confirm.
After you confirm your password, apt will continue to install the rest of the packages.
Congratulations, your LAMP installation is now complete! That was the easy part, now you need to get a few things configured to make your system easy to work with.
Test Apache
Open a web browser and enter the address http://localhost/. You should see a web page that says "It Works!"
Testing Apache
Test php
Now that you know Apache works, you'll want to test the php installation. You'll need to create a file in /var/www called testing.php. Open a terminal and enter:
sudo nano /var/www/testing.php
Enter the following line into the text editor, save the file and exit.
Next, restart Apache with the following terminal command:
sudo /etc/init.d/apache2 restart
Now go back to your web browser and enter the address http://localhost/testing.php/. You should see a page displaying version information for your php installation.

Mengubah batas maksimum koneksi pada Windows XP
Sebagai pengguna komputer, mungkin pernah ada kejadian yaitu pada komputer yang menjalankan Windows XP atau Windows 2000, ketika kita mencoba untuk terhubung ke komputer Windows XP baik untuk sharing folder maupun printer, kita menerima sebuah pesan seperti berikut: "No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept". Hal ini bisa terjadi karena jumlah koneksi dari client ke komputer tersebut sudah mencapai jumlah maksimum yaitu 10 koneksi.
Segala bentuk koneksi baik itu sharing file/ folder, printer, dll yang tidak ada aktivitasnya selama interval waktu tertentu, secara otomatis akan diputuskan oleh sistem. Defaultnya, batas waktu untuk autodisconnect ini adalah sekitar 15 menit. Ketika koneksi ini diputus, maka salah satu jalur koneksi (dari 10 jalur koneksi) dapat dipakai oleh koneksi dari komputer lain yang sebelumnya tidak bisa terhubung (lihat message diatas).
Pada umumnya kita sering merestart komputer server, agar semua jalur koneksi kembali kosong, sehingga user lain yang membutuhkan koneksi ke server dapat segera terhubung. Hal ini tentu sangat merepotkan terlebih jika komputer server (dengan sistem operasi windows xp) ini memiliki jumlah client lebih dari 10. Artinya setiap client harus secara bergantian dalam melakukan koneksi ke server ini.
Untuk mengubah batas maksimum koneksi pada windows XP ini, kita dapat menggunakan program yang bernama Intelligent TCPIP.SYS Patcher (definisi Patch bisa dibaca disini)
Cara menggunakan :
1. Download file pendukung disini
2. Extract file PatchTCPIP.zip
3. Jalankan file PatchTCPIP.exe
4. Pada bagian Do you really want to change the limit to 50? (Y=Yes / N=No / C=Change limit), ketik "Y"
5. Tunggu sampai proses pengeditan berakhir
6. Restart komputer
7. Setelah login kembali, coba jalankan kembali file PatchTCPIP.exe, dan lihat pada bagian Current maximum concurrent half-open connection sudah berubah dari 10 ke 50. Artinya batas maksium koneksi ke windows XP tidak lagi hanya 10 client, tetapi menjadi 50 client.

Blok Facebook di Jam Kerja dengan Firewall di mikrotik Router
Buat firewall untuk block akses ke facebook
/system script add name="fb-unblock" policy=write,read,policy,test,sniff source={/ip firewall filter set [/ip firewall filter find content="facebook"] disable="yes"
/system script add name="fb-block" policy=write,read,policy,test,sniff source={/ip firewall filter set [/ip firewall filter find content="facebook"] disable="no"
Kemudian Atur jadwal sesuai kebutuhan Anda :
/system scheduler add name="fb-08:00" start-date=Nov/09/2009 start-time=08:00:00 interval=1d on-event="fb-block"
/system scheduler add name="fb-12:00" start-date=Nov/09/2009 start-time=12:00:00 interval=1d on-event="fb-unblock
/system scheduler add name="fb-13:00" start-date=Nov/09/2009 start-time=13:00:00 interval=1d on-event="fb-block"
/system scheduler add name="fb-17:00" start-date=Nov/09/2009 start-time=17:00:00 interval=1d on-event="fb-unblock"
