[root@localhost]# tar zxvf proftpd-1.2.10.tar.gz -C /usr/local/proftpd

3. Masuk Ke direktori baru hasil ekstrak:

6. Edit file konfigurasi proftpd dengan text editor

[root@localhostproftpd-1.2.10]# vi /usr/local/etc/proftpd.conf

7. Contoh file konfigurasi proftpd.conf untuk basic ftp server:

# This is a basic ProFTPD configuration file (rename it to

# ‘proftpd.conf’ for actual use. It establishes a single server

# and a single anonymous login. It assumes that you have a user/group

# “nobody” and “ftp” for normal operation and anon.

ServerName “latihan”

ServerType standalone

DefaultServer on

# Port 21 is the standard FTP port.

Port 21

# Umask 022 is a good standard umask to prevent new dirs and files

# from being group and world writable.

Umask 022

# To prevent DoS attacks, set the maximum number of child processes

# to 30. If you need to allow more than 30 concurrent connections

# at once, simply increase this value. Note that this ONLY works

# in standalone mode, in inetd mode you should use an inetd server

# that allows you to limit maximum number of processes per service

# (such as xinetd)

MaxInstances 30

# Set the user and group that the server normally runs at.

User proftpd

Group proftpd

# Normally, we want files to be overwriteable.

AllowOverwrite on

# A basic anonymous configuration, no upload directories.

RequireValidShell off

User ftp

Group ftp

# We want clients to be able to login with “anonymous” as well as “ftp”

UserAlias anonymous ftp

# Limit the maximum number of anonymous logins

MaxClients 10

# We want ‘welcome.msg’ displayed at login, and ‘.message’ displayed

# in each newly chdired directory.

DisplayLogin welcome.msg

DisplayFirstChdir .message

# Limit WRITE everywhere in the anonymous chroot

DenyAll

[root@localhost proftpd-1.2.10]# /usr/local/sbin/proftpd

10. Jika ada error, selalu lakukan cek di /var/log/messages

[root@localhostproftpd 1.2.10]# tail /var/log/messages

11. Jika tidak ada error, lakukan test dengan mencoba ftp server baru tersebut

[root@localhost proftpd-1.2.10]# ftp localhost

Connected to localhost (127.0.0.1).
