Langkah-langkah konfigurasi FTP Server (proftpd) di Ubuntu :
1. Download dan install program proftpd untuk FTP Server.
#apt-get install proftpd

——— IMPORTANT INFORMATION FOR XINETD USERS ———-
The following line will be added to your /etc/inetd.conf file:
ftp stream tcp nowait root /usr/sbin/tcpd /usr/sbin/proftpd
If you are indeed using xinetd, you will have to convert the
above into /etc/xinetd.conf format, and add it manually. See
/usr/share/doc/xinetd/README.Debian for more information.

Coba jalankan proftpd.
#/etc/init.d/proftpd start

2. Jika tidak ada repositori lokal, maka bisa dilakukan secara manual yaitu dengan menginstall file-file dependensi yang dibutuhkan. Install program proftpd (proftpd_1.3.0-24ubuntu1_i386.deb).
root@komputer02-desktop:/# dpkg -i proftpd_1.3.0-24ubuntu1_i386.deb
(Reading database ... 89245 files and directories currently installed.)
Preparing to replace proftpd 1.3.0-24ubuntu1 (using proftpd_1.3.0-24ubuntu1_i386.deb) ...
Unpacking replacement proftpd ...
dpkg: dependency problems prevent configuration of proftpd:
 proftpd depends on libmysqlclient15off (>= 5.0.27-1); however:
  Package libmysqlclient15off is not installed.
 proftpd depends on libpq5; however:
  Package libpq5 is not installed.
dpkg: error processing proftpd (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 proftpd

Dari pesan di atas bisa dilihat bahwa instalasi proftpd masih membutuhkan file dependensi: libmysqlclient15off dan libpq5.
Install dulu file dependensi dengan menggunakan perintah: dpkg -i namafile.deb
Jika sudah, coba install lagi proftpd (proftpd_1.3.0-24ubuntu1_i386.deb)
root@komputer02-desktop:/# dpkg -i libmysqlclient15off_5.0.45-1ubuntu3.4_i386.deb
(Reading database ... 89098 files and directories currently installed.)

Begitu juga dengan file libpq5 dilanjutkan dengan install proftpd.

3. Pilih standalone.


4. Membuat direktori
root@komputer02-desktop:/home# mkdir ftp_shared
root@komputer02-desktop:/home# cd ftp_shared/; mkdir upload download
Set security permission
root@komputer02-desktop:/home/ftp_shared# cd ..
root@komputer02-desktop:/home# sudo chmod 755 ftp_shared/
root@komputer02-desktop:/home# cd ftp_shared/
root@komputer02-desktop:/home/ftp_shared# sudo chmod 755 download/
root@komputer02-desktop:/home/ftp_shared# sudo chmod 777 upload/

5. Membuat user baru untuk FTP
Melalui menu System > Administration > Users and Groups kemudian klik Add user.
misalkan kita menambah user: wiwin, dengan folder homenya: /home/ftp_shared
 

6. Mengkonfigurasi proftpd server
Langkah akhir adalah mengkonfigurasikan proftpd. File konfigurasi proftpd berada di /etc/proftpd/proftpd.conf.
Sebelumnya backup dulu file proftpd.conf dan selanjutnya edit file tersebut.
root@komputer02-desktop:/etc/proftpd# cp proftpd.conf proftpd.conf.asli
root@komputer02-desktop:/etc/proftpd# pico proftpd.conf
#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.


# Includes DSO modules
Include /etc/proftpd/modules.conf

7. Restart service proftpd
root@komputer02-desktop:/# /etc/init.d/proftpd restart
 * Stopping ftp server proftpd [ OK ]
 * Starting ftp server proftpd [ OK ]

8. Sampai di sini, konfigurasi proftpd selesai. Sekarang bisa dicoba upload file dari komputer lain ke komputer yang sudah kita setting sebelumnya. Untuk melakukan transfer file (upload, download) di windows bisa menggunakan program FileZilla atau program FTP lain.
Host – > masukkan hostname/IP komp tujuan (exp. 192.168.1.2)
Username – > masukkan username yang telah dibuat sebelumnya (wiwin)
Password – > Masukkan password dari username
Port – > Masukkan portnya (2008)
Untuk lebih jelasnya bisa dilihat gambar berikut.


9. Untuk melakukan upload dan download dari atau ke komputer tujuan bisa dilakukan dengan drag dan drop.
