Other servers
=============

The Fedora Security Lab Test bench is hosting some services which are usualy
not found on public accessible systems. ``telnet`` was replaced with more secure
systems. Nowadays ``tftp`` is mainly used for provisioning VoIP installations.
Print servers like cups are used in office environments.

To give the students the possibility to work with VPN, an OpenVPN setup with
a static key is included.   

* `openssh`_ (Port 22) encrypts communication sessions over a computer network
  using the SSH protocol
* `dropbear`_ (Port 222) is a lightweight SSH server
* telnet (xinetd) supports  bidirectional interactive text-oriented communication 
* `tftp`_ (xinetd) is a single port TFTP Server based on Trivial File
Transfer Protocol
* `OpenVPN`_ server with a static key
* `cups`_ is a standards-based printing system
* `ngircd`_ is a lightweight Internet Relay Chat server

The tftp server is serving a simple text file. ::

    [fab@laptop011 hhs-tb]$ ls
    [fab@laptop011 hhs-tb]$ tftp 10.0.0.64
    tftp> get info.txt
    tftp> quit
    [fab@laptop011 hhs-tb]$ ls
    info.txt
