Question: How to Enable tls/ssl in proftpd
Benefits of TLS/SSL
TLS/SSL provides numerous benefits to clients and servers over other methods of authentication, including:
– Strong authentication, message privacy, and integrity
– Interoperability
– Algorithm flexibility
– Ease of deployment
– Ease of use
1- Install Proftpd and openssl
apt-get install proftpd openssl yum install proftpd openssl
2- Create SSL Certificates
mkdir /opt/ssl/ cd /opt/ssl
3- Generate ssl certificate with
openssl req -new -x509 -days 365 -nodes -out proftpd.cert.pem -keyout proftpd.key.pem
Generating a 2048 bit RSA private key .....................+++ ..........+++ writing new private key to 'proftpd.key.pem' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:NL State or Province Name (full name) []:Adam Locality Name (eg, city) [Default City]:Adam Organization Name (eg, company) [Default Company Ltd]:Unixmen Organizational Unit Name (eg, section) []:Unixmen Common Name (eg, your name or your server's hostname) []:Unixmen-test Email Address []:@unixmen.com
4- Enable TLS In ProFTPd
Edit /etc/proftpf/proftpd.conf or /etc/proftpd.conf (Ubuntu/Centos)
<IfModule mod_tls.c> TLSEngine on TLSLog /var/log/proftpd/tls.log TLSProtocol SSLv23 TLSOptions NoCertRequest TLSRSACertificateFile /opt/ssl/proftpd.cert.pem TLSRSACertificateKeyFile /opt/ssl/proftpd.key.pem TLSVerifyClient off TLSRequired on </IfModule>
5- Check if proftpd ready with:
# proftpd -vv ProFTPD Version: 1.3.3g (maint) Scoreboard Version: 01040003 Built: Thu Nov 10 2011 16:20:47 UTC
Loaded modules: mod_lang/0.9 mod_ctrls/0.9.4 mod_cap/1.0 mod_vroot/0.9.2 mod_tls/2.4.2 mod_auth_pam/1.1 mod_readme.c mod_ident/1.0 mod_dso/0.5 mod_facts/0.1 mod_delay/0.6 mod_site.c mod_log.c mod_ls.c mod_auth.c mod_auth_file/0.8.3 mod_auth_unix.c mod_xfer.c mod_core.c
6- Now start proftpd
/etc/init.d/proftpd start Starting proftpd: [ OK ]
and is done!
