General Freelancing Networking Virtualbox Windows Windows 8 Linux Hardware Linux Commands Reviews Security Burp Suite Kali Linux Metasploit Server FTP Http Monitoring Smtp Super Tips How to configure vsftpd to use SSL/TLS (FTPS) on CentOS/Ubuntu CentOS FTP Ubuntu By Silver Moon On Jan 3, 2014 No Comments Securing FTP Vsftpd is a widely used ftp server, and if you are setting it up on your server for transferring files, then be aware of the security issues that come along. The ftp protocol has weak security inherent to its design. It transfers https://access.redhat.com/solutions/1375113 all data in plain text (unencrypted), and on public/unsecure network this is something too risky. To fix the issue we have FTPS. It secures FTP communication by encrypting it with SSL/TLS. And this post shows how to setup SSL encryption with vsftpd. Install vsftpd Vsftpd is available in the default repositories of all major distros including debian,ubuntu, centos and fedora and can be http://www.binarytides.com/vsftpd-configure-ssl-ftps/ installed without any hassles. There is only one configuration file named vsftpd.conf that resides in the /etc directory. # ubuntu/debian $ sudo apt-get install vsftpd # centos/fedora # sudo yum install vsftpd The remaining is to configure vsftpd to use ssl encryption for the ftp communication. It is just a 2 step process. Generate a SSL certificate The first step is to create an ssl certificate and key file that vsftpd is going to use for the encryption. The configuration parameter "rsa_cert_file" shall hold the path to the certificate file. It does have a default value that can be found in the man page. $ man vsftpd.conf | grep rsa_cert_file -A 5 rsa_cert_file This option specifies the location of the RSA certificate to use for SSL encrypted connections. Default: /usr/share/ssl/certs/vsftpd.pem Its different across Ubuntu and CentOS. We can store it at any location we like. Create an ssl certificate with the openssl command. We are putting the certificate and key together in a single file. # openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout /etc/ssl/private/vsftpd.pem -out /etc/ssl/private/vsftpd.pem Answer the questions that follow and in a few
of security. the default setup sends everything in the clear and anyone with packet sniffer can see https://community.wd.com/t/howto-securing-ftp-server-with-encryption/95725 your username and password and able to reconstruct the upload/download. This 5 http://www.linuxquestions.org/questions/linux-networking-3/vsftpd-login-problem-879790/ minutes changes will secure the FTP server with encryption key and no additional software. After the changes you will be able to use FTP with everything encrypted. you should be aware of using ssh and warranty thingy. Also, you should be able to use vi editor ftp error or whatever you are comfortable with. The procedure is straight forward: login to your wdmycloud with ssh 2 . do the following: [root@wdmycloud] openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout /etc/ssl/certs/vsftpd.pem -out /etc/ssl/certs/vsftpd.pem this will create an encryption certificate for vsfptd (wdmycloud standard ftp server). it will last for 365 days, and uses 1024 bit encrypted ftp error 530 key. You can change these. it will ask for information to populate the certificate, enter them as you wish. Make it meaningful so you can differentiate it from others. such as your name, city etc ... To configure vsftpd you edit the file /etc/vsftpd.conf and add the following lines: rsa_cert_file=/etc/ssl/certs/vsftpd.pemrsa_private_key_file=/etc/ssl/certs/vsftpd.pemssl_enable=YESallow_anon_ssl=NOforce_local_data_ssl=YESforce_local_logins_ssl=YESssl_tlsv1=YESssl_sslv2=NOssl_sslv3=NOrequire_ssl_reuse=NOssl_ciphers=HIGH Save the file. the FTP server will use ports 5000-5099 for data (look in vsftpd.conf) therefore you need to open (port forward) these on your firewall/router as well as port 21-22 and enable ftp in your dashboard 5. then do [root@wdmycloud] service vsftpd restart I also prefer to reboot, just in case to make sure the changes take hold. Now you need a FTP client that support TLS, Filezilla will do (but I prefer WinSCP). I also use similar on my ipad and laptop from work. The client will negotiate with the server and presented with certificate, accept it since you created it. all connection including username and password is now encrypted with the above key you created. NOTE: THIS WILL ENC
