LinuxQuestions.org - proftpd asks for rsa key everytime, can it be done automatically?

Here is my proftpd.conf file: how do I make it so it doesn't ask for my cert passphrase each time the deamon starts? I remember reading a while ago on a way so it does it automatically...but forget where I saw it. Thanks.

Code:

 ServerName "Gentoo FTP"

ServerType standalone

DeferWelcome off

DefaultServer on

AuthPAM off

AuthPAMConfig ftp



Port 666



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

# from being group and world writable.



Umask 022



MaxInstances 30



# Set the user and group under which the server will run.



User nobody

Group nobody



# Normally, we want files to be overwriteable.

<Directory />

AllowOverwrite on

</Directory>







# chroot for all users of the group ftpuser

DefaultRoot ~ ftpuser



# grant login only for members of the group

<Limit LOGIN>

DenyGroup !ftpuser

</Limit>



# disable root login and require a valid shell (from /etc/shells)

<Global>

RootLogin off

RequireValidShell on

</Global>



UseReverseDNS off

IdentLookups off



# Logging formats

LogFormat default "%h %l %u %t \"%r\" %s %b"

LogFormat auth "%v [%P] %h %t \"%r\" %s"

LogFormat write "%h %l %u %t \"%r\" %s %b"



# logging



# every login

ExtendedLog /var/log/ftp_auth.log AUTH auth



# file/dir access

ExtendedLog /var/log/ftp_access.log WRITE,READ write





<IfModule mod_tls.c>

TLSEngine on

TLSLog /opt/var/proftpd/tls.log

TLSProtocol TLSv1



# Clients are required to use FTP over TLS when talking to this server

# off = clients can connect using insecure FTP or secure FTP/SSL

# on = clients can only connect using secure FTP/SSL

TLSRequired on



# Server's certificate

TLSRSACertificateFile /opt/etc/ftpd/server.crt

TLSRSACertificateKeyFile /opt/etc/ftpd/server.key



# CA the server trusts

TLSCACertificateFile /opt/etc/ftpd/ca.crt



# Authenticate clients that want to use FTP over TLS

# off = client SSL certificates are not requried

# on = client SSL certificates are required

TLSVerifyClient off

</IfModule>

EDIT: (SOLVED)

1. Remove the encryption from the RSA private key (while preserving the original file):

$ cp server.key server.key.org
$ openssl rsa -in server.key.org -out server.key

2. Make sure the server.key file is now only readable by root:

$ chmod 400 server.key
