Red Hat - CentOS - Fedora, Video Tutorials

After we have installed BIND as a master DNS server (centos01) (as explained in my recent video), we can now set up a secondary DNS server (centos02) with BIND on CentOS. centos02 acts as a backup if there are problems with centos01. This tutorial will show you how to setup and configure Secondary (Slave) BIND DNS Server on RHEL 6.x or CentOS 6.x Note: centos01.linuxlab.local is Primary (Master) DNS server for linuxlab.local domain We'll make centos02.linuxlab.local ( 192.168.0.22) as secondary dns server for linuxlab.local domain Steps: 1. Define centos02 as Name Server in the primary zone 2. Install bind on other server 3. Configure /etc/named.conf on centos02 (secondary dns server) 4. Allow zone transfer to only our secondary dns server in primary dns server allow-transfer { 192.168.0.22; }; 5. start…

How to Enable SSL Support for VSFTPD – RHEL 6 – CentOS 6

Red Hat - CentOS - Fedora, Video Tutorials

FTP, or file transfer protocol, was a popular way to transfer files between local and remote computers in the past. Traditional FTP is rather insecure. When you login, your username and password are transmitted in clear text, raising the possibility of your credentials being sniffed. If you still want to use FTP instead of a more secure alternative like SFTP, which uses the SSH protocol to implement file transfers, you can secure it somewhat by configuring FTP to use SSL. You can quite easily configure your vsftpd server to use OpenSSL encryption, so that usernames & password, and even data files, are encrypted during transfer. It takes just a few simple steps. Steps: 1. Check whether the latest mod_ssl installed locate mod_ssl 2. Install the latest mod_ssl via yum yum…
