Ftp can be secured using ftps to connect. Below outlines a configuration to support such a setup using TLS/SSL.
I usually use the epel repository to install proftpd:
yum --enablerepo=epel install proftpdConfigure for tls/ssl connection:
<IfModule mod_tls.c>
TLSEngine on
TLSRequired off
TLSRSACertificateFile /etc/pki/tls/proftpd/server.cert.pem
TLSRSACertificateKeyFile /etc/pki/tls/proftpd/server.key.pem
TLSVerifyClient off
TLSRenegotiate required off
TLSLog /var/log/proftpd/tls.log
</IfModule>chroot and bindsocket to listen to single IP:
SocketBindTight on
DefaultRoot ~Setup passive ftp ports:
</Global>
...
...
PassivePorts 50000 51000
</Global>Create the certs:
mkdir -p /etc/pki/tls/proftpd
cd /etc/pki/tls/proftpd
openssl req -new -x509 -days 9999 -nodes -out server.cert.pem -keyout server.key.pemCreate /etc/pam.d/ftp so PAM can authenticate for proftpd:
#%PAM-1.0
auth required pam_unix.so nullok
account required pam_unix.so
session required pam_unix.soAdd "/bin/false" to "/etc/shells" file and use it as the shell type when creating new users:
useradd -s /bin/false <ftp_user>Bookmark/Search this post with:
