Use the chkconfig command to deactivate telnet, even after the next tmp]# chkconfig telnet off You can also use the chkconfig -list command to verify that telnet will be started on the next tmp]# chkconfig –list | grep telnet telnet: tmp]# To set up a Telnet server use the chkconfig command to activate tmp]# chkconfig telnet on

Setting up the telnet server is easy to do, but the procedure differs between Linux distributions. Here is an example of someone logging into a remote server named smallfry from server bigboy. You enter the word telnet and then the IP address or server name to which you want to connect. The command to do remote logins via telnet from the command line is simple.

I’ll show you how to limit your exposure to Telnet’s insecurities are mentioned later in this chapter. Many network devices don’t have SSH clients, making telnet the only means of accessing other devices and servers from them. In spite of this, the older Telnet application remains popular. A more secure method for remote logins would be via Secure Shell (SSH) which uses varying degrees of encryption. This means that it is possible for someone to use a network analyzer to peek into your data packets and see your username and password. One of the disadvantages of Telnet is that the data is sent as clear text. The Telnet server RPM is installed and disabled by default on Fedora Linux.

Telnet is a program that allows users to log into your server and get a command prompt just as if they were logged into the VGA console. The chkconfig command does that for you automatically will also stops or starts the application accordingly too! Here is an example of the activation and deactivation of the Samba SWAT web GUI management tmp]# chkconfig swat tmp]# chkconfig swat off

You don’t have to edit these files to activate or deactivate the application. This governs whether xinetd is allowed to start them or not. Each configuration file has a disable statement that you can set to yes or no. Xinetd-managed applications all store their configuration files in the /etc/xinetd.d directory. To get xinetd configured to start at boot you can use the chkconfig tmp]# chkconfig xinetd on You can start/stop/restart xinetd after booting by using the following tmp]# service xinetd tmp]# service xinetd tmp]# service xinetd restart The starting and stopping of the xinetd daemon is controlled by the by scripts in the /etc/init.d directory and its behavior at boot time is controlled by chkconfig. Fortunately you usually don’t have to edit this file so that day to day xinetd operation is frequently limited to only starting and stopping xinetd managed applications. The xinetd RPM is installed by default in Fedora Linux and uses /etc/nf as its main configuration file.
