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

# "nobody" and "ftp" for normal operation and anon.

# from being group and world writable.

# 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

# in each newly chdired directory.

– Jalankan proftpd:
[root@taubat proftpd-1.2.4]# /usr/local/sbin/proftpd

– Jika ada error, selalu lakukan cek di /var/log/messages, anda akan menemukan informasi yg sangat berharga di situ 🙂
[root@taubat proftpd-1.2.4]# tail /var/log/messages

– Jika tidak ada error, lakukan test dengan mencoba ftp server baru anda 🙂

[root@taubat proftpd-1.2.4]# ftp localhost
